Android activates a compatibility mode for apps that declare orientation or
resizability restrictions. Compatibility mode ensures acceptable app behavior on
large screen devices and foldable flip phones but with suboptimal usability.

[Per-app overrides](https://developer.android.com/guide/practices/device-compatibility-mode#per-app_overrides) enable device manufacturers, virtual
device owners^[1](https://developer.android.com/guide/practices/device-compatibility-mode#fn1)^, and users to change app behavior to improve app layout or
prevent apps from breaking on select devices.

## Android 16

Android 16 (API level 36) ignores screen orientation, aspect ratio, and app
resizability restrictions to improve the layout of apps on form factors with
smallest width \>= 600dp.

The following per-app overrides are nonfunctional for apps that target API level
36:

- [FORCE_RESIZE_APP](https://developer.android.com/guide/practices/device-compatibility-mode#force_resize_app)
- [FORCE_NON_RESIZE_APP](https://developer.android.com/guide/practices/device-compatibility-mode#force_non_resize_app)

- [OVERRIDE_EXCLUDE_CAPTION_INSETS_FROM_APP_BOUNDS](https://developer.android.com/guide/practices/device-compatibility-mode#override_exclude_caption_insets_from_app_bounds)

### Opt out

Your app can target API level 36 but opt out of the Android 16 behavior, in
which case [OVERRIDE_ANY_ORIENTATION_TO_USER](https://developer.android.com/guide/practices/device-compatibility-mode#override_any_orientation_to_user)
is not applicable.
| **Warning:**
|
| - All overrides other than `OVERRIDE_ANY_ORIENTATION_TO_USER` are applicable even though your app opts out of the Android 16 behavior; and so, your app's screen orientation, aspect ratio, and resizability restrictions can still be overridden if device manufacturers have implemented the overrides.
| - Users can override app aspect ratio in **Settings** even if your app opts out. See [User
|   per-app overrides](https://developer.android.com/guide/practices/device-compatibility-mode#user_per-app_overrides).
| - Desktop windowing:
|   - Orientation restrictions are overridden despite your app opting out.
|   - Resizability restrictions are respected if your app opts out. However, scaled resizing can be applied.

#### Declare manifest property

To opt out of the API level 36 behavior, declare the
`PROPERTY_COMPAT_ALLOW_RESTRICTED_RESIZABILITY` manifest property.

To opt out for a specific activity, set the property in the `<activity>`
element:  

    <activity ...>
        <property
            android:name="android.window.PROPERTY_COMPAT_ALLOW_RESTRICTED_RESIZABILITY"
            android:value="true" />
        ...
    </activity>

To opt out for your entire app, set the property in the `<application>` element:  

    <application ...>
        <property
            android:name="android.window.PROPERTY_COMPAT_ALLOW_RESTRICTED_RESIZABILITY"
            android:value="true" />
        ...
    </application>

| **Warning:** The Android framework will eliminate the opt-out capability in API level 37. For apps that target API level 37 or higher, orientation, aspect ratio, and resizability restrictions will always be ignored on displays that are at least sw600dp.

## Reference devices

The following devices may require per-app overrides because of unusual
configurations or configurations that are not well supported by apps:

- **Tablets:** The natural orientation of some tablets, such as Pixel Tablet, is landscape. A device is in its natural orientation when [`Display#getRotation()`](https://developer.android.com/reference/kotlin/android/view/Display#getRotation()) returns [`Surface.ROTATION_0`](https://developer.android.com/reference/kotlin/android/view/Surface#rotation_0). If apps assume `ROTATION_0` is portrait, app layouts and camera preview can be mismatched to the device display.
- **Landscape foldables:** Some foldable devices, such as Pixel Fold, are in portrait orientation when folded, but landscape orientation when unfolded. If apps assume the unfolded orientation is portrait, [flickering
  loops](https://developer.android.com/guide/practices/device-compatibility-mode#flickering_loops) or layout issues are likely.
- **Foldable flip phones:** Unfolded flip phones are typically in portrait orientation. But, when folded, the phones usually have a small display in landscape orientation. Apps must identify and accommodate the different orientations of the displays.
- **External displays:** Select devices can start a desktop windowing session on external, connected displays. Apps must query external displays for information such as screen size and resolution; otherwise, apps may make incorrect assumptions about the displays, which can lead to incorrect app behavior.
- **Car displays:** Many, but not all, car displays are landscape. Developing [parked apps](https://developer.android.com/training/cars/parked) for car displays is similar to developing for tablets.

## Common compatibility issues

Apps experience compatibility issues most often because of app orientation
restrictions, resizability and aspect ratio restrictions, incorrect handling of
camera preview orientation, and misused APIs.

### Letterboxing

Letterboxing positions the app in the center of the screen or, on large screens,
to one side or the other for convenient access. Mattes (solid‑colored bars
or blurred wallpaper) fill the unused display area along the sides or top and
bottom of the app.

Letterboxing happens often on large screen devices because the dimensions and
aspect ratio of the device display are usually different from those of standard
phones, for which most apps are designed.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/letterboxing.png)  
**Figure 1.** App restricted to portrait orientation is letterboxed on landscape tablet and foldable.

#### Issue

App doesn't support all display configurations because the app has fixed
orientation, fixed aspect ratio, or is not resizable.

Configuration settings that control app orientation and resizability include the
following:

- [`screenOrientation`](https://developer.android.com/reference/android/R.attr#screenOrientation): Specifies a fixed orientation for
  an app. Apps can also set orientation at runtime by using
  [`Activity#setRequestedOrientation()`](https://developer.android.com/reference/kotlin/android/app/Activity#setrequestedorientation).

- [`resizeableActivity`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity): Indicates whether the system can
  resize apps to fit windows of varying dimensions. On Android 11 (API level
  30) and lower, specifies whether apps support multi‑window mode. On
  Android 12 (API level 31) and higher, specifies whether apps support
  multi‑window mode on small screens (compact
  [window size class](https://developer.android.com/develop/ui/compose/layouts/adaptive/use-window-size-classes)). On Android 12 and higher, apps
  support multi‑window mode on large screens (medium or expanded window
  size class) regardless of this setting.

- [`maxAspectRatio`](https://developer.android.com/reference/android/R.attr#maxAspectRatio): Specifies the maximum aspect ratio
  supported by the app. Only apps with `resizeableActivity` set to `false` can
  set `maxAspectRatio`.

- [`minAspectRatio`](https://developer.android.com/reference/android/R.attr#minAspectRatio): Specifies the minimum aspect ratio
  supported by the app. Only apps with `resizeableActivity` set to `false` can
  set `minAspectRatio`.

### App restricted to portrait orientation not usable on landscape device.

#### Optimization

App should support all device and [multi-window mode](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-multi-window-mode) display
orientations and sizes. Remove all orientation and fixed aspect ratio
restrictions from your app layouts and app manifest file.

check_circle

### App supports all device orientations.

#### Compatibility workaround

If an app with fixed orientation or fixed aspect ratio runs in a window where
the app does not directly support the window size or orientation, Android
letterboxes the app to preserve continuity.

Beginning with Android 12 (API level 31) and continuing with 12L (API level 32),
the platform applies a variety of enhancements to letterboxed apps. Device
manufacturers implement the UI enhancements. You don't need to do any additional
development for your app to benefit from the improvements.

Android 12 (API level 31) introduces the following aesthetic enhancements, which
can be configured by device manufacturers:

- **Rounded corners:** The corners of the app window have a more refined look.
- **System bar transparency:** Status and navigation bars, which overlay the app, are semitransparent, making icons on the bars always viewable over the letterbox background.
- **Configurable aspect ratio:** The aspect ratio of the app can be adjusted to improve the app's appearance.

![](https://developer.android.com/static/images/guide/practices/compatibility-mode/enhanced_letterboxing.png)  
**Figure 2.** Letterboxed app with UI enhancements.

12L (API level 32) adds the following functional improvements:

- **Configurable positioning:** On large screens, device manufacturers can
  position the app to the left or right side of the display, making
  interaction easier.

- **Redesigned restart button:** Device manufacturers can give the restart
  button for [size compatibility mode](https://developer.android.com/guide/practices/device-compatibility-mode#size_compatibility_mode) a new look
  for better recognition by users.

Android 13 (API level 33) adds a user education dialog about positioning the
letterboxed app on screen or including the letterbox in split‑screen mode:  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/enhanced_letterboxing_user_dialog.png)  
**Figure 3.** Letterboxed app with user education dialog.

### Size compatibility mode

Size compatibility mode is letterboxing that maintains the app aspect ratio and
includes a restart control. The control enables users to restart the app and
redraw the display. Android invokes size compatibility mode for apps that are
nonresizable. When an activity moves to a display container that is incompatible
with the activity's dimensions, the system may rescale the app to fill the
device display in at least one dimension.

Device configuration changes that can trigger size compatibility mode include
the following:

- Device rotation
- Foldable device folding or unfolding
- Change between full screen and split-screen display modes

#### Issue

Size compatibility mode typically applies to activities that are restricted in
orientation or aspect ratio and are configured (or determined by the system) to
be nonresizable.

Your app is considered to be resizable---and won't be placed in size
compatibility mode---if it meets any of the following criteria:

- Is resizable with [`resizeableActivity="true"`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity)
- Supports [picture-in-picture (PIP)](https://developer.android.com/develop/ui/views/picture-in-picture#declaring) mode
- Is [embedded](https://developer.android.com/develop/ui/views/layout/activity-embedding)
- Has the [`FORCE_RESIZE_APP`](https://developer.android.com/guide/practices/device-compatibility-mode#force_resize_app) per-app override applied by the device manufacturer (properties set by the app are ignored)

If your app *does not* meet any of the conditions, it is considered not
resizable and could be placed in size compatibility mode.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/size_compatibility_mode_issue.gif)  
cancel

### Nonresizable app crashes in multi-window mode.

#### Optimization

App should support all display sizes. Make your app resizable by setting the
`android:resizeableActivity` attribute of the [`<activity>`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity)
or [`<application>`](https://developer.android.com/guide/topics/manifest/application-element#resizeableActivity) element to `true` in the
app manifest. Design responsive/adaptive layouts for your app. For more
information, see
[Support different display sizes](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-different-display-sizes) and [Support
multi-window mode](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-multi-window-mode#resizeableActivity).  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/size_compatibility_mode_optimization.gif)  
check_circle

### App works in all window sizes.

#### Compatibility workaround

Android places an app in size compatibility mode when the system determines the
display of the letterboxed app can be improved by rescaling the app to fill the
display window in at least one dimension. The system displays a restart control
which recreates the app process, recreating the activity and redrawing the
display. See also [Processes and threads overview](https://developer.android.com/guide/components/processes-and-threads).  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/size_compatibility_mode_workaround.gif)  
warning

### Portrait-only app letterboxed in landscape orientation, rescaled by restart control.

### Display compatibility mode

Display compatibility mode prevents an app from restarting when the app moves
between different displays, which can trigger a configuration change such as a
[color mode](https://developer.android.com/guide/topics/manifest/activity-element#colormode),
[touchscreen availability](https://developer.android.com/guide/topics/manifest/activity-element#config), or
[screen density](https://developer.android.com/guide/topics/manifest/activity-element#config) change.

Display compatibility mode mode is enabled by default for games (based on the
[`android:appCategory`](https://developer.android.com/guide/topics/manifest/application-element#appCategory) flag) to improve stability and continuity.
Unlike size compatibility mode, display compatibility mode does not freeze the
app's configuration. The app can still receive all configuration updates through
APIs such as the [`onConfigurationChanged()`](https://developer.android.com/reference/kotlin/android/app/Activity#onconfigurationchanged) callback but is spared from a
disruptive restart. This means games that properly support APIs such as
onConfigurationChanged() can still responsively update their UI even if
they are in display compatibility mode.

To opt out of display compatibility mode and handle configuration changes in
your app, declare support for the configuration changes in the app's
`AndroidManifest.xml` file, and handle the configuration changes in the
onConfigurationChanged() callback.  

    <activity
        android:name=".MyGameActivity"
        android:configChanges="colorMode|touchscreen|density|...">
        ...
    </activity>

### Flickering loops

When an app doesn't support all display orientations, it might repeatedly
request new orientations when a configuration change occurs, creating an
infinite loop that makes the display flicker or the app rotate endlessly.

#### Issue

On Android 12 (API level 31) and higher, device manufacturers can configure
their devices to ignore orientation restrictions specified by apps and instead
enforce compatibility modes. For example, a foldable device could ignore an
activity's [`android:screenOrientation="portrait"`](https://developer.android.com/guide/topics/manifest/activity-element#screen)
setting when the activity is displayed on the device's landscape tablet-size,
inner screen.

If an app's orientation restrictions are ignored, the app can programmatically
set its orientation by calling
[`Activity#setRequestedOrientation()`](https://developer.android.com/reference/kotlin/android/app/Activity#setrequestedorientation). The call
triggers an app restart if the app is not handling configuration changes (see
[Handle configuration changes](https://developer.android.com/guide/topics/resources/runtime-changes)). After the
restart, the app's orientation restrictions are again ignored, the app repeats
the call to `setRequestedOrientation()`, the call triggers an app restart, and
so on in a self-perpetuating loop.

Another way you might encounter this is when the
[natural orientation](https://developer.android.com/reference/kotlin/androidx/browser/trusted/ScreenOrientation#NATURAL()) (the *usual* orientation as
determined by Android) of a device screen is landscape (that is, calling
[`Display#getRotation()`](https://developer.android.com/reference/kotlin/android/view/Display#getRotation()) returns
[`Surface.ROTATION_0`](https://developer.android.com/reference/kotlin/android/view/Surface#rotation_0) while the device has a landscape aspect
ratio). Historically, apps have assumed that `Display.getRotation() =
Surface.ROTATION_0` means the device is in portrait orientation, but this is not
always the case, for example, on the inner screen of some foldable devices and
on some tablets.

An app in landscape orientation on a foldable inner display, might check the
screen rotation, receive a value of `ROTATION_0`, assume the natural orientation
of the device is portrait, and call
`setRequestedOrientation(`[`ActivityInfo.SCREEN_ORIENTATION_PORTRAIT`](https://developer.android.com/reference/kotlin/android/content/pm/ActivityInfo#screen_orientation_portrait)
`)` to reconfigure the app layout. After the app restarts (in landscape
orientation), it might again check the screen rotation, receive a value of
`ROTATION_0`, call
`setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)`, and
continue the infinite loop.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/flickering_loops_issue.gif)  
cancel

### Landscape-only app on portrait display makes repeated calls to `Activity#setRequestedOrientation()`.

#### Optimization

Apps should *not* do the following:

- Set a default orientation with `Activity#setRequestedOrientation()` in the activity `onCreate()` method because the orientation request can be triggered unexpectedly by unhandled configuration changes
- Assume the natural orientation of the device (`ROTATION_0`) is portrait
- Set orientation based on signals not related to the current window size such as `Display#getRotation()`, presence of a [`FoldingFeature`](https://developer.android.com/reference/kotlin/androidx/window/layout/FoldingFeature), or [deprecated APIs](https://developer.android.com/guide/practices/device-compatibility-mode#misused_apis).

![](https://developer.android.com/static/images/guide/practices/compatibility-mode/flickering_loops_optimization.gif)  
check_circle

### App handles configuration change, does not have orientation restrictions, so does not enter a flickering loop.

#### Compatibility workaround

Android ignores calls to `Activity#setRequestedOrientation()` in the following
situations:

- The activity has already relaunched from a previous call to the method or
  the camera compat force rotation treatment has been enabled (see [Camera
  preview](https://developer.android.com/guide/practices/device-compatibility-mode#camera_preview) below).

  Device manufacturers can apply this behavior to an app with
  [`OVERRIDE_ENABLE_COMPAT_IGNORE_REQUESTED_ORIENTATION`](https://developer.android.com/guide/practices/device-compatibility-mode#override_enable_compat_ignore_requested_orientation).
- The activity made more than two orientation requests in one second, which
  indicates a loop has occurred. Of the two requests in the loop, Android uses
  the one that maximizes the app display area.

  Device manufacturers can apply this behavior to an app with
  [`OVERRIDE_ENABLE_COMPAT_IGNORE_ORIENTATION_REQUEST_WHEN_LOOP_DETECTED`](https://developer.android.com/guide/practices/device-compatibility-mode#override_enable_compat_ignore_orientation_request_when_loop_detected).
- Virtual device owners have overridden the method call on select devices.

| **Note:** Apps can opt out of both device manufacturer overrides, but can opt in only for `OVERRIDE_ENABLE_COMPAT_IGNORE_REQUESTED_ORIENTATION`.

### Camera preview

The camera preview (or viewfinder) of camera apps can be misaligned or distorted
on tablets, laptops, and foldable displays.

#### Issue

The [Android Compatibility Definition Document](https://source.android.com/docs/compatibility/cdd) states that a
camera image sensor "MUST be oriented so that the long dimension of the camera
aligns with the screen's long dimension."

Apps often assume that device orientation and camera sensor orientation are
portrait---a reasonable assumption on standard mobile phones. But the
natural orientation of tablets and laptops and their camera sensors can be
landscape. Also, new form factors like foldables can have multiple natural
orientations and multiple camera sensors in varying orientations.

Starting an activity with a camera orientation the app does not expect or
switching between different cameras or device screens (for foldables) can cause
a misaligned or distorted camera preview.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/camera_preview_issue.png)  
cancel

### Misaligned and distorted camera preview on large screen foldable.

#### Optimization

Camera apps must correctly identify and manage device orientation and camera
sensor orientation to present a correctly aligned and scaled camera preview.
Apps must calculate device rotation, sensor rotation, and screen or window
aspect ratio, and then apply the results to the camera preview. For detailed
guidance, see [Camera preview](https://developer.android.com/training/camera2/camera-preview) and [Introducing Camera
Viewfinder](https://android-developers.googleblog.com/2022/11/introducing-camera-viewfinder.html).  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/camera_preview_optimization.png)  
check_circle

### Camera preview correctly aligned and scaled in all device orientations.

#### Compatibility workaround

A device is in natural orientation when [`Display#getRotation()`](https://developer.android.com/reference/kotlin/android/view/Display#getRotation())
returns [`Surface.ROTATION_0`](https://developer.android.com/reference/kotlin/android/view/Surface#rotation_0). The system calculates
[`CameraCharacteristics.SENSOR_ORIENTATION`](https://developer.android.com/reference/kotlin/android/hardware/camera2/CameraCharacteristics#sensor_orientation)
from the device's natural orientation. Android aligns the portrait window of
portrait‑restricted apps with the natural orientation of the device, which
is what most apps expect. Android also crops the camera sensor image when the
sensor orientation is landscape and the camera preview is portrait. The specific
workarounds include the following:

- **Force rotate camera previews for portrait-restricted apps:** Apps
  restricted to portrait orientation expect the device's natural orientation
  and the camera sensor orientation to be portrait. However, on Android 12
  (API level 31) and higher, apps can run in multiple device orientations if
  device manufacturers ignore the orientation specification.

  When a portrait-restricted app is connected to the camera, Android force
  rotates the app to align the app portrait window with the natural
  orientation of the device.

  On some tablets (see [reference devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices)), the app
  portrait window is rotated to full screen portrait to align with the
  device's natural orientation. The app occupies the full screen after force
  rotation.  
  ![](https://developer.android.com/static/images/guide/practices/compatibility-mode/camera_preview_workaround_tablet.gif)  
  warning

  ### Tablet --- Force rotation of portrait-restricted app.

  On the landscape inner screen of foldables (see [reference
  devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices)), portrait-only activities are rotated to
  landscape to align with the unfolded natural orientation. The app is
  letterboxed after force rotation.  
  ![](https://developer.android.com/static/images/guide/practices/compatibility-mode/camera_preview_workaround_foldable.gif)  
  warning

  ### Foldable --- Force rotation of portrait-restricted app. The app is also letterboxed.

  | **Note:** Force rotation does not happen if your app is responsive and handles portrait and landscape orientations.
- **Inner front camera cropping:** The inner front camera sensor on some
  foldables is in landscape orientation. In addition to force rotating the
  camera preview on the foldable inner display, Android crops the inner front
  (landscape) camera field of view so that the sensor captures a view opposite
  the device orientation.

- **Force refresh camera previews:** The system cycles through activity
  methods `onStop()` and `onStart()` (by default) or `onPause()` and
  `onResume()` (applied by the
  [OVERRIDE_CAMERA_COMPAT_ENABLE_REFRESH_VIA_PAUSE](https://developer.android.com/guide/practices/device-compatibility-mode#override_camera_compat_enable_refresh_via_pause)
  per-app override) after force rotation to make sure the camera preview is
  properly displayed.

- **Aspect ratio scaling:** The system dynamically changes the aspect ratio of
  the force rotated camera preview to a higher minimum aspect ratio, which
  ensures the camera preview is properly scaled.

App developers can override these workarounds if the apps handle camera preview
correctly. See [Per-app overrides](https://developer.android.com/guide/practices/device-compatibility-mode#per-app_overrides).

### Commonly misused APIs

As Android has added support for features like multi‑window mode and
devices like foldables, legacy APIs have been deprecated and replaced by
up‑to‑date APIs that work for all display sizes and device form
factors. However, the deprecated APIs are still available for backward
compatibility.

Some `View` APIs are designed for special purposes that are not always well
understood by developers.

#### Issue

Developers continue to use deprecated `Display` APIs and incorrectly assume the
APIs return the app bounds instead of device display area bounds. Or developers
mistakenly use special‑purpose view APIs to get general display metrics.
The result is miscalculations when repositioning UI elements after app window
resizing events, causing layout issues.

**Deprecated and commonly misused Display APIs:**

- [`getMetrics()`](https://developer.android.com/reference/kotlin/android/view/Display#getmetrics)
- [`getSize()`](https://developer.android.com/reference/kotlin/android/view/Display#getSize(android.graphics.Point))
- [`getRealMetrics()`](https://developer.android.com/reference/kotlin/android/view/Display#getRealMetrics(android.util.DisplayMetrics))
- [`getRealSize()`](https://developer.android.com/reference/kotlin/android/view/Display#getRealSize(android.graphics.Point))
- [`getRectSize()`](https://developer.android.com/reference/kotlin/android/view/Display#getRectSize(android.graphics.Rect))
- [`getWidth()`](https://developer.android.com/reference/kotlin/android/view/Display#getWidth())
- [`getHeight()`](https://developer.android.com/reference/kotlin/android/view/Display#getHeight())

For more information, see
[Support multi-window mode](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-multi-window-mode#window_metrics).

**Misused view APIs:**

- [`getWindowVisibleDisplayFrame()`](https://developer.android.com/reference/android/view/View#getWindowVisibleDisplayFrame(android.graphics.Rect))
- [`getLocationOnScreen()`](https://developer.android.com/reference/android/view/View#getLocationOnScreen(int%5B%5D))

![](https://developer.android.com/static/images/guide/practices/compatibility-mode/misused_APIs_issue.png)  
cancel

### Deprecated API miscalculates app bounds. App content goes off screen.

#### Optimization

Never rely on physical display size for positioning UI elements. Migrate your
app to APIs based on [`WindowMetrics`](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowMetrics), including the following
`WindowManager` APIs:

- Platform:

  - [`getCurrentWindowMetrics()`](https://developer.android.com/reference/kotlin/android/view/WindowManager#getcurrentwindowmetrics)
  - [`getMaximumWindowMetrics()`](https://developer.android.com/reference/kotlin/android/view/WindowManager#getmaximumwindowmetrics)
- Jetpack:

  - [`WindowMetricsCalculator#computeCurrentWindowMetrics()`](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowMetricsCalculator#computeCurrentWindowMetrics(android.app.Activity))

  - [`WindowMetricsCalculator#computeMaximumWindowMetrics()`](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowMetricsCalculator#computeMaximumWindowMetrics(android.app.Activity))

![](https://developer.android.com/static/images/guide/practices/compatibility-mode/misused_APIs_optimization.png)  
check_circle

### API correctly calculates app window metrics.

#### Compatibility workaround

Two overrides adjust the deprecated `Display` APIs and misused `View` APIs to
return the app bounds:
[`ALWAYS_SANDBOX_DISPLAY_APIS`](https://developer.android.com/guide/practices/device-compatibility-mode#always_sandbox_display_apis) for `Display`
APIs; [`OVERRIDE_SANDBOX_VIEW_BOUNDS_APIS`](https://developer.android.com/guide/practices/device-compatibility-mode#override_sandbox_view_bounds_apis)
for `View` APIs. `ALWAYS_SANDBOX_DISPLAY_APIS` is also applied by default to
apps that qualify for size compatibility mode.

### Transparent activities

Transparent activities are the result of transparent background styles, for
example:  

    <style name="Transparent" parent="AppTheme">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
    </style>

Themes related to dialogs, such as `Theme.MaterialComponents.Dialog`, can
include styles that make activities transparent.

Transparent activities don't cover all the available display space, which makes
them difficult to manage because the available display area can change based on
configuration changes like device rotation, device folding and unfolding, and
multi‑window mode.

#### Issue

A transparent activity should conform to the bounds of the first opaque activity
below the transparent activity in the task activity stack. However, an opaque
activity that launches a permission dialog can be a
*trampoline* (an activity that launches another activity then disappears); and
so, the system can't determine the bounds of the trampoline activity that
launched the transparent permission dialog activity.

cancel

### Dialog mispositioned because the activity was launched from a trampoline.

#### Optimization

Transparent activities inherit their constraints from the top-most opaque
activity beneath them in a task's activity stack. The opaque activity must be
available for the entire lifecycle of the transparent activity, from activity
creation to destruction. For this reason, don't launch permission requests from
trampoline activities.

If a trampoline activity launches a permission request, the user might not be
able to see the permission dialog because the trampoline activity will have been
destroyed before the user has had a chance to respond to the dialog, and the
dimensions and position of the dialog activity might have been calculated
incorrectly.

Apps should always launch permission requests from activities that remain
visible until the user has made a permission decision.

##### Rounded corners

An activity can be transparent because of a style that specifies background
transparency or because the contents of the activity don't fill the available
display space. If a transparent activity fills the available display space, the
system automatically applies rounded corners to the activity when configured to
do so by the device manufacturer. But, if a transparent activity (like a
permission dialog) doesn't fill the available space, it's up to you to decide
whether or not to apply rounded corners.

Permission dialogs don't fill the available display space because the dialog
layout typically uses [LayoutParams.WRAP_CONTENT](https://developer.android.com/reference/android/view/ViewGroup.LayoutParams#WRAP_CONTENT) rather than
[LayoutParams.MATCH_PARENT](https://developer.android.com/reference/android/view/ViewGroup.LayoutParams#MATCH_PARENT).

### Dialog with rounded corners correctly positioned over visible launching activity.

#### Compatibility workaround

Keep activities that launch dialog activities visible until the user has
responded to the dialog.

The system ensures that a transparent activity inherits all constraints from the
first opaque activity beneath the transparent activity in the activity stack,
including constraints related to:

- Size compatibility mode
- Orientation
- Aspect Ratio

### Unity games

Unity games run on Android full screen or in multi‑window mode. However,
many Unity games lose focus and stop drawing content when the app is placed in
multi‑window mode.

#### Issue

Unity added a [`Resizable Window`](https://docs.unity3d.com/2019.4/Documentation/Manual/class-PlayerSettingsAndroid.html#resizable)
option in Unity 2019.4 to support multi‑window mode on Android. However,
the initial implementation did not react to the [activity lifecycle in
multi-window mode](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-multi-window-mode#lifecycle) correctly, causing
UnityPlayer to suspend playback when the app loses focus. The player rendered a
black screen or the last, frozen frame of the game. Gameplay resumed only when
the user tapped the screen. Many apps using the Unity engine face this issue and
render as a black window in multi‑window mode.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/unity_games_issue.gif)  
cancel

### Game loses focus in multi-window mode and renders as a black window.

#### Optimization

Upgrade Unity to 2019.4.40 or later and re‑export your game. Keep the
`Resizable Window` option checked in the
[Android Player settings](https://docs.unity3d.com/2019.4/Documentation/Manual/class-PlayerSettingsAndroid.html#resizable), otherwise
the game pauses when not in focus even though the game is entirely visible in
multi‑window mode.  
![](https://developer.android.com/static/images/guide/practices/compatibility-mode/unity_games_optimization.gif)  
check_circle

### Game renders content correctly in multi-window mode even when not in focus.

#### Compatibility workaround

Device manufacturers can apply the
[`OVERRIDE_ENABLE_COMPAT_FAKE_FOCUS`](https://developer.android.com/guide/practices/device-compatibility-mode#override_enable_compat_fake_focus)
per‑app override to provide a fake focus event to an app in
multi‑window mode. The override enables the activity to redraw content and
not be blacked out.

### Desktop windowing

When apps run in a desktop windowing environment, they may encounter
additional compatibility modes.

Apps with locked orientation are freely resizable. Even if an activity is locked
to [portrait orientation](https://developer.android.com/guide/topics/manifest/activity-element#screen), users can still resize the app to landscape
orientation.  
![Animation of a portrait app being resized to landscape.](https://developer.android.com/static/images/guide/practices/compatibility-mode/windowing_free_resizing.gif)  
check_circle

### Apps with locked orientation can still be freely resized.

However, if an activity is declared as nonresizable ([resizeableActivity =
false](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity)), the activity UI scales while maintaining the
same aspect ratio.  
![Animation of app being resized. UI scales to fill the desktop window.](https://developer.android.com/static/images/guide/practices/compatibility-mode/windowing_non_resizable.gif)  
check_circle

### Activities declared as nonresizable have their UI scaled.

#### Camera preview in desktop windowing

When apps in desktop windowing start a camera preview, the viewfinder has its UI
scaled while keeping its original aspect ratio. The rest of the app window can be
freely resized.

## Test your app for compatibility issues

To test your app and understand how it behaves on different form factors, take
advantage of the following resources:

- **Device streaming:** To test your app on production devices (including [reference devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices)) hosted in Google data centers, see [Android Device Streaming, powered by Firebase](https://developer.android.com/studio/preview/android-device-streaming)
- **Emulators in Android Studio:** For information on creating emulators for reference devices, see [Create and manage virtual devices](https://developer.android.com/studio/run/managing-avds)
- **Android Studio resizable emulator:** For information on accessing virtual devices, see [Run apps on the Android Emulator](https://developer.android.com/studio/run/emulator)

### Is letterboxed

Verify that each activity can use all of the display space available to the app.
First, declare the following code in your test folder:


### Kotlin

```kotlin
fun isLetterboxed(activity: AppCompatActivity): Boolean {
    if (isInMultiWindowMode) return false

    val wmc = WindowMetricsCalculator.getOrCreate()
    val currentBounds = wmc.computeCurrentWindowMetrics(this).bounds
    val maxBounds = wmc.computeMaximumWindowMetrics(this).bounds

    val isScreenPortrait = maxBounds.height() > maxBounds.width()

    return if (isScreenPortrait) {
        currentBounds.height() < maxBounds.height()
    } else {
        currentBounds.width() < maxBounds.width()
    }
}https://github.com/android/snippets/blob/1da1d9d645cd1a8e693981900e04d6bc32287a5c/misc/src/main/java/com/example/snippets/DeviceCompatibilityModeKotlinSnippets.kt#L33-L47
```

### Java

```java
public boolean isLetterboxed(AppCompatActivity activity) {
    if (activity.isInMultiWindowMode()) {
        return false;
    }

    WindowMetricsCalculator wmc = WindowMetricsCalculator.getOrCreate();
    Rect currentBounds = wmc.computeCurrentWindowMetrics(activity).getBounds();
    Rect maxBounds = wmc.computeMaximumWindowMetrics(activity).getBounds();

    boolean isScreenPortrait = maxBounds.height() > maxBounds.width();

    return (isScreenPortrait)
        ? currentBounds.height() < maxBounds.height()
        : currentBounds.width() < maxBounds.width();
}https://github.com/android/snippets/blob/1da1d9d645cd1a8e693981900e04d6bc32287a5c/misc/src/main/java/com/example/snippets/DeviceCompatibilityModeJavaSnippets.java#L29-L43
```

<br />

Then run a test to assert the behavior and make sure the target activity is not
letterboxed:


### Kotlin

```kotlin
@get:Rule
val activityRule = ActivityScenarioRule(MainActivity::class.java)

@Test
fun activity_launched_notLetterBoxed() {
    activityRule.scenario.onActivity {
        assertFalse(it.isLetterboxed())
    }
}https://github.com/android/snippets/blob/1da1d9d645cd1a8e693981900e04d6bc32287a5c/misc/src/androidTest/java/com/example/snippets/DeviceCompatibilityModeTestKotlinSnippets.kt#L28-L36
```

### Java

```java
@Rule
public ActivityScenarioRule<MainActivity> rule = new ActivityScenarioRule<>(MainActivity.class);

@Test
public void activity_launched_notLetterBoxed() {
    try (ActivityScenario<MainActivity> scenario =
        ActivityScenario.launch(MainActivity.class)) {
            scenario.onActivity( activity -> {
                assertFalse(activity.isLetterboxed());
            });
        }
}https://github.com/android/snippets/blob/1da1d9d645cd1a8e693981900e04d6bc32287a5c/misc/src/androidTest/java/com/example/snippets/DeviceCompatibilityModeTestJavaSnippets.java#L29-L40
```

<br />

Ideally, run this kind of test only until it passes and asserts that your app's
activities take up the entire display space available to the app. Test your app
on all device types to ensure consistent behavior.

## Per-app overrides

Android provides overrides that change the configured behavior of apps. For
example, the [`FORCE_RESIZE_APP`](https://developer.android.com/guide/practices/device-compatibility-mode#force_resize_app) override instructs the
system to bypass size compatibility mode and resize the app to fit display
dimensions even if [`resizeableActivity="false"`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity) is
specified in the app manifest.

Device manufacturers apply overrides to select apps---or all apps---on
specific large screen devices. On Android 14 (API level 34) and higher, users
can apply overrides to apps through device settings. On Android 16 (API level
36) and higher, virtual device owners apply overrides on select devices the
virtual device owners manage.
| **Note:** Per-app overrides are intended to fix broken app behavior or improve the user experience.

### User per-app overrides

On Android 14 and higher, a settings menu enables users to change the aspect
ratio of apps. Large screen devices such as the [reference
devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices) implement the menu.

The menu contains a list of all apps installed on the device. Users choose an
app and then set the app aspect ratio to 3:4, 1:1, full screen, or other value
configured by the device manufacturer. Users can also reset the aspect ratio to
the app default, which is specified in the app manifest.
| **Note:** If users override the app aspect ratio to full screen, the app becomes resizable and able to enter multi‑window mode, as if the app had been configured with the manifest attribute [`resizeableActivity="true"`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity).

Apps can opt out of the compatibility override by setting the following [`PackageManager.Property`](https://developer.android.com/reference/android/content/pm/PackageManager.Property) tags:

- **PROPERTY_COMPAT_ALLOW_USER_ASPECT_RATIO_OVERRIDE**

  To opt out of the user aspect ratio compatibility override, add the property
  to your app manifest and set the value to `false`:  

      <application>
          <property
              android:name="android.window.
              PROPERTY_COMPAT_ALLOW_USER_ASPECT_RATIO_OVERRIDE"
              android:value="false" />
      </application>

  Your app will be excluded from the list of apps in device settings. Users
  won't be able to override the app's aspect ratio.

  Setting the property to `true` has no effect.
- **PROPERTY_COMPAT_ALLOW_USER_ASPECT_RATIO_FULLSCREEN_OVERRIDE**

  To opt out of the full-screen option of the user aspect ratio compatibility
  override, add the property to your app manifest and set the value to
  `false`:  

      <application>
          <property
              android:name="android.window.PROPERTY_COMPAT_ALLOW_USER_ASPECT_RATIO_FULLSCREEN_OVERRIDE"
              android:value="false" />
      </application>

  The full-screen option is removed from the list of aspect ratio options in
  device settings. Users won't be able to apply the full-screen override to
  your app.
  | **Caution:** If [`PROPERTY_COMPAT_ALLOW_USER_ASPECT_RATIO_OVERRIDE`](https://developer.android.com/guide/practices/device-compatibility-mode#aspect_ratio_override) is `false`, this property has no effect.

  Setting this property to `true` has no effect.

| **Note:** To implement the property tags, your app must include the Jetpack [WindowManager](https://developer.android.com/jetpack/androidx/releases/window) library dependency.

**Optimize your app for all screens:** Don't set aspect ratio restrictions in
your app. Use [window size classes](https://developer.android.com/develop/ui/compose/layouts/adaptive/use-window-size-classes) to support different
layouts based on the amount of available display space.

### Device per-app overrides

Device manufacturers and virtual device owners (select trusted and privileged
apps) apply overrides on a per‑app basis on specific devices, including
tablets, foldables, ChromeOS devices, and car displays. The [reference
devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices) may apply some of the overrides to a variety of
apps by default.

Apps can opt out of most overrides (see the [Per-app
overrides](https://developer.android.com/guide/practices/device-compatibility-mode#device_manufacturer_overrides_table) table below).

You can test your app with overrides enabled or disabled using the compatibility
framework (see [Compatibility framework tools](https://developer.android.com/guide/app-compatibility/test-debug)).
When enabled, overrides apply to the entire app.

You can also use the [Android Debug Bridge (adb)](https://developer.android.com/tools/adb) to enable or disable
overrides and determine which overrides apply to your app.

Enable or disable overrides as follows:  

    adb shell am compat enable/disable <override name/id> <package>

For the [reference devices](https://developer.android.com/guide/practices/device-compatibility-mode#reference_devices), check which overrides apply to
your app:  

    adb shell dumpsys platform_compat | grep <package name>

| **Note:** If `dumpsys platform_compat` returns `true` for `OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION`, your app is *not* force rotated, as mentioned in [Camera preview compatibility
| workaround](https://developer.android.com/guide/practices/device-compatibility-mode#camera_preview_workaround).
|
| If `dumpsys platform_compat` returns `false` for `OVERRIDE_CAMERA_LANDSCAPE_TO_PORTRAIT`, your app is *not* inner front camera cropped (see [Camera preview compatibility workaround](https://developer.android.com/guide/practices/device-compatibility-mode#camera_preview_workaround)).

The following table lists available overrides along with guidance on how to
optimize your app so the app does not need to rely on overrides. You can add
property flags to your app manifest to opt out of some overrides.

### FORCE_RESIZE_APP

Forces the packages to which the override is applied to be resizable and able to
enter multi‑window mode. Applies to all displays sizes.

#### How apps can achieve same result as override

In the app manifest, set the [`android:resizeableActivity`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity)
attribute to `true`.

#### How to optimize apps

Use responsive/adaptive layouts to enable apps to adapt to all display sizes and
aspect ratios. See
[Support different display sizes](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-different-display-sizes).
| **Tip:** To support resizing while disabling multi‑window mode with `android:resizeableActivity=false`, add the following `<meta-data>` tag to the app manifest:
|
| `<meta-data
| android:name="android.supports_size_changes" android:value="true" />`

#### How to disable or opt out of override

Set the property flag `PROPERTY_COMPAT_ALLOW_RESIZEABLE_ACTIVITY_OVERRIDES` to
`false`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_COMPAT_ALLOW_RESIZEABLE_ACTIVITY_OVERRIDES"
      android:value="true|false"/>

#### adb commands to test override

To apply the override and make app resizable:  

    adb shell am compat enable FORCE_RESIZE_APP <package>

To remove the override:  

    adb shell am compat disable FORCE_RESIZE_APP <package>

**Note:** The commands only temporarily apply or remove the override.

### FORCE_NON_RESIZE_APP

Forces the packages to which the override is applied to be nonresizable and
enter size compatibility mode on configuration changes. Applies to all display
sizes.

#### How apps can achieve same result as override

Set both the `android:resizeableActivity` attribute and
`android.supports_size_changes` metadata flag to `false` in the app manifest,
and declare either an orientation or aspect ratio restriction.

#### How to optimize apps

All apps that behave well if resized should either have
`android:resizeableActivity` or `android.supports_size_changes` set to `true`.
Other apps should be improved to behave well when resized. See
[android:resizeableActivity](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity).

#### How to disable or opt out of override

Set the property flag `PROPERTY_COMPAT_ALLOW_RESIZEABLE_ACTIVITY_OVERRIDES` to
`false`.

#### Property flags to adjust override

#### adb commands to test override

To apply the override and make app nonresizable:  

    adb shell am compat enable FORCE_NON_RESIZE_APP <package>

    adb shell am compat disable FORCE_NON_RESIZE_APP <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_MIN_ASPECT_RATIO

The gatekeeper for all overrides that force a given minimum aspect ratio.

#### How apps can achieve same result as override

Set [`android:minAspectRatio`](https://developer.android.com/reference/android/R.attr#minAspectRatio) at the activity or app level.

#### How to optimize apps

Don't set aspect ratio restrictions in your app. Make sure your app [supports
different display sizes](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-different-display-sizes). Use window size
classes to support different layouts based on the amount of space your app has
on the screen. See the
[Compose `WindowSizeClass` API](https://developer.android.com/reference/kotlin/androidx/compose/material3/windowsizeclass/WindowSizeClass) and [View
`WindowSizeClass` API](https://developer.android.com/reference/kotlin/androidx/window/core/layout/WindowSizeClass).

#### How to disable or opt out of override

Specify an aspect ratio restriction or set the property flag
`PROPERTY_COMPAT_ALLOW_MIN_ASPECT_RATIO_OVERRIDE` to `false`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_COMPAT_ALLOW_MIN_ASPECT_RATIO_OVERRIDE"
      android:value="false"/>

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_MIN_ASPECT_RATIO <package>

### OVERRIDE_ANY_ORIENTATION

Enables the following overrides to override any orientation:

- [OVERRIDE_UNDEFINED_ORIENTATION_TO_PORTRAIT](https://developer.android.com/guide/practices/device-compatibility-mode#override_undefined_orientation_to_portrait)
- [OVERRIDE_UNDEFINED_ORIENTATION_TO_NOSENSOR](https://developer.android.com/guide/practices/device-compatibility-mode#override_undefined_orientation_to_nosensor)
- [OVERRIDE_LANDSCAPE_ORIENTATION_TO_REVERSE_LANDSCAPE](https://developer.android.com/guide/practices/device-compatibility-mode#override_landscape_orientation_to_reverse_landscape)

#### How apps can achieve same result as override

Set the [`activity:screenOrientation`](https://developer.android.com/guide/topics/manifest/activity-element#screen) manifest attribute,
or use the [`Activity#setRequestedOrientation()`](https://developer.android.com/reference/kotlin/android/app/Activity#setrequestedorientation) API.

#### How to optimize apps

Your app should support all orientations. An orientation change is a
configuration change, which can be handled either of two ways: letting the
system destroy and recreate the app, or managing the configuration changes
yourself. If you manage configuration changes yourself, the app state can be
retained by using `ViewModel`. In very limited cases, you can decide to lock the
orientation on small displays only, although doing so might not scale as well as
letting the user rotate the app as needed. On Android 12L and higher versions,
fixed orientation can be overridden by device configuration. For more
information about handling configuration changes and supporting all
orientations, see [Handle configuration changes](https://developer.android.com/guide/topics/resources/runtime-changes),
[ViewModel overview](https://developer.android.com/topic/libraries/architecture/viewmodel), and [App orientation restricted on
phones but not on large screen devices](https://developer.android.com/guide/topics/large-screens/large-screen-cookbook#restricted_app_orientation).

#### How to disable or opt out of override

Set the property flag
[`PROPERTY_COMPAT_ALLOW_ORIENTATION_OVERRIDE`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_COMPAT_ALLOW_ORIENTATION_OVERRIDE)
to `false`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_COMPAT_ALLOW_ORIENTATION_OVERRIDE"
      android:value="true|false"/>

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_ANY_ORIENTATION <package>

To remove the override:  

    adb shell am compat disable OVERRIDE_ANY_ORIENTATION <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_ANY_ORIENTATION_TO_USER

Enables app to fill the available display space. Overrides any orientation,
resizability, and aspect ratio restrictions specified in the app manifest. Also
ignores any calls to
[`Activity#setRequestedOrientation()`](https://developer.android.com/reference/kotlin/android/app/Activity#setrequestedorientation) or
[`Activity#getRequestedOrientation()`](https://developer.android.com/reference/kotlin/android/app/Activity#getrequestedorientation).

#### How apps can achieve same result as override

- Do *not* set the [`android:screenOrientation`](https://developer.android.com/guide/topics/manifest/activity-element#screen) manifest
  attribute, or set the attribute to `"user"`.

- Set the [`android:resizeableActivity`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity) manifest
  attribute to `true`.

  | **Note:** Settings for [`android:minAspectRatio`](https://developer.android.com/reference/android/R.attr#minAspectRatio) and [`android:maxAspectRatio`](https://developer.android.com/reference/android/R.attr#maxAspectRatio) are ignored if `resizeableActivity` is set to `true`.
- On small screens, to support app resizing while disabling multi‑window
  mode with `android:resizeableActivity=false`, set the
  `android.supports_size_changes` metadata flag to `true`. Do *not* set
  `minAspectRatio` and `maxAspectRatio`.

  | **Note:** On Android 12 (API level 31), all apps run in multi-window mode on large screens (medium or expanded [window size class](https://developer.android.com/develop/ui/compose/layouts/adaptive/use-window-size-classes)) regardless of app configuration. See [Support multi-window mode](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-multi-window-mode#resizeableActivity).

#### How to optimize apps

Enable your app to support all orientations; don't set a `screenOrientation`
specification in your app's manifest. Support app resizability,
multi‑window mode, and all display aspect ratios by setting the
`android:resizeableActivity` attribute in your app's manifest to `true`. See
[Support different display sizes](https://developer.android.com/develop/ui/compose/layouts/adaptive/support-different-display-sizes).

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_RESPECT_REQUESTED_ORIENTATION

Excludes packages from ignore orientation request behavior that can be enabled
by device manufacturers for a display area or the whole display.

#### How apps can achieve same result as override

Not applicable. The problem should be solved in the application logic.

#### How to optimize apps

See [`OVERRIDE_ANY_ORIENTATION`](https://developer.android.com/guide/practices/device-compatibility-mode#override_any_orientation).

#### How to disable or opt out of override

No opt-out. Disabling the override can be dangerous if the app is not compatible
with a device that has the device manufacturer ignore orientation request
setting enabled. Contact [Android Developer
Relations](mailto:android-devrel-ops@google.com) to disable the override.

#### Property flags to adjust override

No property flags for this override.

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_RESPECT_REQUESTED_ORIENTATION <package>

To remove the override:  

    adb shell am compat disable OVERRIDE_RESPECT_REQUESTED_ORIENTATION <package>

**Note:** The commands only temporarily apply or remove the override.

### NEVER_SANDBOX_DISPLAY_APIS

Forces packages to never have [`Display`](https://developer.android.com/reference/kotlin/android/view/Display) API sandboxing applied
for a letterboxed or size compatibility mode activity. The `Display` APIs
continue to provide display area bounds.

#### How apps can achieve same result as override

Declare activities resizable by either setting the
[`android:resizeableActivity`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity) manifest attribute to `true`
or the `android.supports_size_changes` metadata flag to `true`.

#### How to optimize apps

Apps that declare they are fully resizable should never rely upon display size
to position UI elements. Migrate your app to up‑to‑date APIs that
provide `WindowMetrics`. If you are using Jetpack Compose, take advantage of the
[`WindowSizeClass`](https://developer.android.com/reference/kotlin/androidx/compose/material3/windowsizeclass/WindowSizeClass) API to draw the UI based on how much screen
area the app has on the current display. See
[Use window size classes](https://developer.android.com/develop/ui/compose/layouts/adaptive/use-window-size-classes).

#### How to disable or opt out of override

No opt-out. Migrate from deprecated APIs.

#### Property flags to adjust override

No property flags for this override.

#### adb commands to test override

To apply the override:  

    adb shell am compat enable NEVER_SANDBOX_DISPLAY_APIS <package>

To remove the override:  

    adb shell am compat disable NEVER_SANDBOX_DISPLAY_APIS <package>

**Note:** The commands only temporarily apply or remove the override.

### ALWAYS_SANDBOX_DISPLAY_APIS

Forces packages to always have [`Display`](https://developer.android.com/reference/kotlin/android/view/Display) API sandboxing applied
regardless of windowing mode. The `Display` APIs always provide the app bounds.

#### How apps can achieve same result as override

Declare activities nonresizable by either setting the
[`android:resizeableActivity`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity) attribute to `false` or the
`android.supports_size_changes` metadata flag to `false`.

#### How to optimize apps

Apps that declare they are fully resizable should never rely on display size to
position UI elements. Migrate your app from deprecated APIs to
up‑to‑date APIs that provide `WindowMetrics`. See
[`WindowMetricsCalculator`](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowMetricsCalculator).

#### How to disable or opt out of override

No opt-out. Migrate from deprecated APIs.

#### Property flags to adjust override

No property flags for this override.

#### adb commands to test override

To apply the override:  

    adb shell am compat enable ALWAYS_SANDBOX_DISPLAY_APIS <package>

To remove the override:  

    adb shell am compat disable ALWAYS_SANDBOX_DISPLAY_APIS <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_SANDBOX_VIEW_BOUNDS_APIS

Forces packages to sandbox the following [`View`](https://developer.android.com/reference/kotlin/android/view/View) APIs to activity bounds:

- [`getWindowVisibleDisplayFrame()`](https://developer.android.com/reference/android/view/View#getWindowVisibleDisplayFrame(android.graphics.Rect))
- [`getLocationOnScreen()`](https://developer.android.com/reference/android/view/View#getLocationOnScreen(int%5B%5D))

#### How apps can achieve same result as override

Resolve the issue in application code by using APIs that provide the bounds of
the app window and offsets relative to the app window rather than the bounds of
the device display and offsets relative to the device display.

#### How to optimize apps

Apps should use `View` APIs, taking into account the possibility of letterboxing
and multi-window mode being applied to the app. See
[`WindowMetricsCalculator`](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowMetricsCalculator).

#### How to disable or opt out of override

Set property flag
[`PROPERTY_COMPAT_ALLOW_SANDBOXING_VIEW_BOUNDS_APIS`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_COMPAT_ALLOW_SANDBOXING_VIEW_BOUNDS_APIS)
to `false`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_COMPAT_ALLOW_SANDBOXING_VIEW_BOUNDS_APIS"
      android:value="false"/>

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_SANDBOX_VIEW_BOUNDS_APIS <package>

To remove the override:  

    adb shell am compat disable OVERRIDE_SANDBOX_VIEW_BOUNDS_APIS <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION

Disables force rotation. Improves the user experience on some apps.

#### How apps can achieve same result as override

camera compatibility guidance, see
[Introducing Camera Viewfinder](https://android-developers.googleblog.com/2022/11/introducing-camera-viewfinder.html) and [Support
resizable surfaces in your camera
app](https://developer.android.com/codelabs/android-camera2-preview#0).

#### How to disable or opt out of override

Set property flag
[`PROPERTY_CAMERA_COMPAT_ALLOW_FORCE_ROTATION`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_CAMERA_COMPAT_ALLOW_FORCE_ROTATION)
to `true`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_CAMERA_COMPAT_ALLOW_FORCE_ROTATION"
      android:value="true|false"/>

#### adb commands to test override

To apply the override, which removes force rotation:  

    adb shell am compat enable OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION <package>

To remove the override, which allows force rotation to happen:  

    adb shell am compat disable OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_CAMERA_COMPAT_DISABLE_REFRESH

Disables activity refresh after force rotation. Improves the user experience
when refresh causes state loss in apps.

#### How apps can achieve same result as override

To remove the override, which allows activity refresh:  

    adb shell am compat disable OVERRIDE_CAMERA_COMPAT_DISABLE_REFRESH <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_CAMERA_COMPAT_ENABLE_REFRESH_VIA_PAUSE

Makes the packages it is applied to do activity refresh using an `onResume()`
→ `onPause()` → `onResume()` cycle rather than `onResume()` →
`onStop()` → `onResume()` after camera compatibility force rotation.

#### How apps can achieve same result as override

Set property flag
[`PROPERTY_CAMERA_COMPAT_ENABLE_REFRESH_VIA_PAUSE`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_CAMERA_COMPAT_ENABLE_REFRESH_VIA_PAUSE)
to `true`.

#### How to optimize apps

See
[OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION](https://developer.android.com/guide/practices/device-compatibility-mode#override_camera_compat_disable_force_rotation).

#### How to disable or opt out of override

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_CAMERA_LANDSCAPE_TO_PORTRAIT

Forces camera output to be cropped to the opposite orientation when portrait
camera orientation doesn't align with the natural device orientation. Many apps
don't handle this situation and display stretched images otherwise.

#### How apps can achieve same result as override

Set property flag
[`PROPERTY_COMPAT_OVERRIDE_LANDSCAPE_TO_PORTRAIT`](https://developer.android.com/reference/android/content/pm/PackageManager#PROPERTY_COMPAT_OVERRIDE_LANDSCAPE_TO_PORTRAIT)
to `true`.

#### How to optimize apps

See
[OVERRIDE_CAMERA_COMPAT_DISABLE_FORCE_ROTATION](https://developer.android.com/guide/practices/device-compatibility-mode#override_camera_compat_disable_force_rotation).

#### How to disable or opt out of override

To remove the override, which removes inner front camera cropping:  

    adb shell am compat disable OVERRIDE_CAMERA_LANDSCAPE_TO_PORTRAIT <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_DISABLE_MEDIA_PROJECTION_SINGLE_APP_OPTION

Prevents apps from opting out of app screen sharing (see
[Media projection](https://developer.android.com/media/grow/media-projection#partial_screen_sharing_opt_out)). Implemented when apps misuse the
[`createConfigForDefaultDisplay()`](https://developer.android.com/reference/kotlin/android/media/projection/MediaProjectionConfig#createconfigfordefaultdisplay) API to force
full‑screen capture and jeopardize user privacy by exposing the contents
of notifications, which are captured with full‑screen but not app screen
sharing, and all apps regardless of windowing mode.

#### How apps can achieve same result as override

Allow the default media projection behavior (implemented in Android 14, API
level 34, with [`createScreenCaptureIntent()`](https://developer.android.com/reference/kotlin/android/media/projection/MediaProjectionManager#createscreencaptureintent)),
which enables users to decide whether to share the full screen or a single app
window regardless of windowing mode. Or call
[`createScreenCaptureIntent(MediaProjectionConfig)`](https://developer.android.com/reference/kotlin/android/media/projection/MediaProjectionManager#createscreencaptureintent_1)
with a [`MediaProjectionConfig`](https://developer.android.com/reference/kotlin/android/media/projection/MediaProjectionConfig) argument returned from a
call to [`createConfigForUserChoice()`](https://developer.android.com/reference/kotlin/android/media/projection/MediaProjectionConfig#createconfigforuserchoice).

#### How to optimize apps

Allow users to select whether to share the entire device display or an app
window during media projection, which as of Android 14 is the default behavior.

Make your app resizable ([`resizeableActivity="true"`](https://developer.android.com/guide/topics/manifest/activity-element#resizeableActivity)) to
support multi‑window mode.

#### How to disable or opt out of override

Because of the seriousness of user privacy, your app cannot disable or opt out
of this override.

#### Property flags to adjust override

None.

#### adb commands to test override

To apply the override, which cancels the app's opt out of partial screen sharing
(that is, enables partial screen sharing):  

    adb shell am compat enable OVERRIDE_DISABLE_MEDIA_PROJECTION_SINGLE_APP_OPTION <package>

To remove the override, which allows the app's opt out of partial screen
sharing:  

    adb shell am compat disable OVERRIDE_DISABLE_MEDIA_PROJECTION_SINGLE_APP_OPTION <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_ENABLE_COMPAT_FAKE_FOCUS

Enables sending fake focus for unfocused apps in split‑screen mode. Some
game engines wait to get focus before drawing the content of the app; and so,
fake focus helps apps avoid staying blacked out when they are resumed and do not
yet have focus.

#### How apps can achieve same result as override

Set property flag
[`PROPERTY_COMPAT_ENABLE_FAKE_FOCUS`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_COMPAT_ENABLE_FAKE_FOCUS) to
`true`.

#### How to optimize apps

You can avoid this issue if your app handles multiple orientations and
configuration changes well. Make your app large screen ready by following the
[Large screen app quality](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality) guidelines.

If you run the Unity game engine, upgrade to version 2019.4.40 or later and
re‑export your game. Keep the **Resizable Window** option checked in
the [Android Player](https://docs.unity3d.com/2019.4/Documentation/Manual/class-PlayerSettingsAndroid.html#resizable)
settings.

#### How to disable or opt out of override

Set property flag
[`PROPERTY_COMPAT_ENABLE_FAKE_FOCUS`](https://developer.android.com/reference/android/view/WindowManager#PROPERTY_COMPAT_ENABLE_FAKE_FOCUS) to
`false`.

#### Property flags to adjust override

    <property android:name="android.window.PROPERTY_COMPAT_ENABLE_FAKE_FOCUS"
      android:value="true|false"/>

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_ENABLE_COMPAT_FAKE_FOCUS <package>

To remove the override:  

    adb shell am compat disable OVERRIDE_ENABLE_COMPAT_FAKE_FOCUS <package>

**Note:** The commands only temporarily apply or remove the override.

### OVERRIDE_EXCLUDE_CAPTION_INSETS_FROM_APP_BOUNDS

When the override is enabled, the activity receives configuration coupled with
caption bar insets. Normally, caption bar insets are decoupled from
configuration.
| **Note:** The override applies only if the activity targets Android 14 (SDK level 34) or lower. See [Behavior changes: Apps targeting Android 15 or higher](https://developer.android.com/about/versions/15/behavior-changes-15#stable-configuration).

#### How apps can achieve same result as override

Enable edge‑to‑edge display or update the app's target SDK to API
level 35 or higher. See the following:

- Compose: [About window insets](https://developer.android.com/develop/ui/compose/system/insets)
- Views: [Display content edge-to-edge in views](https://developer.android.com/develop/ui/views/layout/edge-to-edge)
- Configuration: [Behavior changes: Apps targeting Android 15 or higher](https://developer.android.com/about/versions/15/behavior-changes-15#stable-configuration)

#### How to optimize apps

You can avoid this issue if your app enables edge‑to‑edge display or
targets API level 35 or higher.

#### How to disable or opt out of override

Enable edge‑to‑edge display or target API level 35 or higher.

#### Property flags to adjust override

None.

#### adb commands to test override

To apply the override:  

    adb shell am compat enable OVERRIDE_EXCLUDE_CAPTION_INSETS_FROM_APP_BOUNDS <package>

To remove the override:  

    adb shell am compat disable OVERRIDE_EXCLUDE_CAPTION_INSETS_FROM_APP_BOUNDS <package>

**Note:** The commands only temporarily apply or remove the override.
