Android P has a feature of Restrictions on non-SDK interfaces.
=> https://developer.android.com/preview/restrictions-non-sdk-interfaces
If you have a method like below, you will face java.lang.NoSuchMethodException: setAnimationScales [class [F] error. This is because of the non-sdk interface feature.
private fun animationHandler() {
try {
val asInterface = Class.forName("android.view.IWindowManager\$Stub").getDeclaredMethod("asInterface", IBinder::class.java)
val getService = Class.forName("android.os.ServiceManager").getDeclaredMethod("getService", String::class.java)
val windowManagerClazz = Class.forName("android.view.IWindowManager")
setAnimationScalesMethod = Class.forName("android.view.IWindowManager").getDeclaredMethod("setAnimationScales", FloatArray::class.java)
getAnimationScalesMethod = windowManagerClazz.getDeclaredMethod("getAnimationScales")
windowManagerObject = asInterface.invoke(null, getService.invoke(null, "window") as IBinder)
} catch (e: Exception) {
throw RuntimeException("Failed to access animation methods", e)
}
}
To avoid the error, we can call below adb commands.
adb shell settings put global hidden_api_policy_pre_p_apps 1 adb shell settings put global hidden_api_policy_p_apps 1
After this, calling setAnimationScales succeeds.
I’ve appended the note in https://github.com/KazuCocoa/DroidTestHelper#note-for-android-p .
BTW, we can get P image from https://dl.google.com/android/repository/sys-img/google_apis_playstore/x86-P_r02.zip . After downloading it and putting it in /Users/username/Library/Android/sdk/system-images/android-P/android_apis_playstore, you can create Android P image via AVDManager.
