## Tools to build scrcpy-server
## To build aidl
Source1:	https://android.googlesource.com/platform/system/tools/aidl/+archive/%{android_version}.tar.gz#/aidl.tar.gz
Source2:	https://android.googlesource.com/platform/system/libbase/+archive/%{android_version}.tar.gz#/libbase.tar.gz
Source3:	https://android.googlesource.com/platform/system/logging/+archive/%{android_version}.tar.gz#/logging.tar.gz
Source4:    https://android.googlesource.com/platform/system/core/+archive/%{android_version}.tar.gz#/core.tar.gz
# cmake file for aidl
Source5:	CMakeLists.txt

## To build d8
Source6:	https://android.googlesource.com/platform/dalvik/+archive/%{android_version}.tar.gz#/dalvik.tar.gz
## build core-lambda-stubs.jar

## To build android.jar
## noramlly we should use metalava on source files to generate signature files and stub java class.
## however it's not possbile to build metalava

## this jar is a zip of stub java file. (not compiled class file)
## to download single file "?format=TEXT" is required, however it is base64 encoded
## could download folder as a tar.gz, however other files may have license issue, like android.jar
## or the last way we manually craft all missing stub dependencies for scrcpy-server (about 3.2M / 8M of original stub.jar) (1.7M/4.9M of compiled)
Source7:	https://android.googlesource.com/platform/prebuilts/fullsdk/platforms/+/refs/heads/main/android-%{sdk_version}/android-stubs-src.jar?format=TEXT#/android-stubs-src.jar.b64

## framework.aidl
## https://android.googlesource.com/platform/prebuilts/fullsdk/platforms/+/refs/heads/main/android-36.tar.gz 
## however this contains properietry assets 
## The link is not downloadable
## https://android.googlesource.com/platform/prebuilts/fullsdk/platforms/+/refs/heads/main/android-36/framework.aidl
## The links' content is base64 encoded
## https://android.googlesource.com/platform/prebuilts/fullsdk/platforms/+/refs/heads/main/android-36/framework.aidl?format=text
## so we just craft our own framework.aidl with necessary imports in prep step.
