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
This also solves reports of this log message:
"INFO: The key you just pressed is not recognized by SDL. To help get this
fixed, please report this to the SDL forums/mailing list
<https://discourse.libsdl.org/> EVDEV KeyCode 330"
(EVDEV KeyCode 330 is BTN_TOUCH.)
Fixes Bugzilla #4147.
- 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.
- Currently, it tries to Attach the JVM first and update the thread local storage, which are two operations.
Now, it simply gives back the JNI Env stored for the thread.
- Android_JNI_SetupThreadi() should only be used for external.
For internal SDL thread, it's already called in RunThread() (SDL_systhread.c),
and other thread are Java threads which don't need to be attached. i
(even if it doesn't hurt to do it, since it's a no-op).
- JNI_OnLoad is filled with pthread_create, GetEnv, AttachCurrentThread...
It's called for all shared libraries which may don't want this setup,
and loading libraries can be also modified to be done from a static context,
or with relinker. So it's not really clear how, who and what it sets up.
=> Reduce this function to the minimal
SDLThread is a Java Thread, it's not needed to call 'Detach' from the JVM.
Clear mThreadKey, so that the pthread_create destructor is not called for this
thread.
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.
