InputDevice.SOURCE_CLASS_* are one bit
More readable to check that the source has this class_joystick set,
compared to the other statements, where the source is gamepad or dpad.
(Clean-up from bug 3958)
by checking Android_Window validity
- SDLThread: user application is exiting:
SDL_VideoQuit() and clearing SDL_GetVideoDevice()
- ActivityThread is changing orientation/size
surfaceChanged() > Android_SetScreenResolution() > SDL_GetVideoDevice()
- Separate function into Android_SetScreenResolution() and Android_SendResize(),
formating, and mark Android_DeviceWidth/Heigh as static
- If you call onPause() before CreateWindow(), SDLThread will run in infinite loop in background.
- If you call onPause() between a DestroyWindow() and a new CreateWindow(), semaphores are invalids.
SDLActivity.java: the first resume() starts the SDLThread, don't call
nativeResume() as it would post ResumeSem. And the first pause would
automatically be resumed.
SDLActivity thread priority is unchanged, by default -10 (THREAD_PRIORITY_VIDEO).
SDLAudio thread priority was -4 (SDL_SetThreadPriority was ignored) and is now -16 (THREAD_PRIORITY_AUDIO).
SDLThread thread priority was 0 (THREAD_PRIORITY_DEFAULT) and is -4 (THREAD_PRIORITY_DISPLAY).
Can be check by adding in build.grable:
gradle.projectsEvaluated {
tasks.withType(JavaCompile) {
options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
}
}

- destroy Android_ActivityMutex
- display any SDL error message that may have occured in this thread,
since SDL_GetError() is thread specific, and user has no access to it.
In the usual case, first call to onNativeOrientationChanged() is done before
SDL has been initialised and would just set an error message
"Video subsystem has not been initialized" without sending the event.
Default launch mode (standard) allows multiple instances of the SDLActivity.

Not sure this is intended in SDL as this doesn't work. There are static
variables in Java, in C code which make this impossible (allow one android_window) and
also Audio print errors.
There is also some code added in onDestroy as if it would be able to
re-initialize: https://hg.libsdl.org/SDL/rev/27686adb08c3
Bug Android activity life-cycle seems to show there is not transition to get out
of onDestroy()
https://developer.android.com/reference/android/app/Activity#ActivityLifecycle
( can be tested with "adb shell am start my.package.org/.MainActivity"
and "adb shell am start -n my.package.org/.MainActivity" )
Send me a message if there are real use-case for this !
This fixes issues for applications that have a large number of shared libraries
