Sylvain Becker d52ba78b29 Fixed bug 4246 - Android: orientation between portrait<->landscape doesn't work
Improve handling of landscape/portrait orientation. Promote to SCREEN_ORIENTATION_SENSOR_* when needed.
Android window can be somehow resizable.
If SDL_WINDOW_RESIZABLE is set, window size change is allowed, for instance when orientation changes (provided the hint allows it).

Sylvain Becker f91b87859c Android: minimum size for IME, so that it takes focus
In API 28, 0 width views can't take focus, so if someone tries to position the IME without setting a width, they'll stop getting text events.

Tested on Android 9: with a 0 size, it would send correctly letters a, b, c, etc. but not numbers.

Sam Lantinga 1a38853e02 Fixed bug 4566 - Hot-plugging Bluetooth controller causes force-quit on Android
Anthony @ POW Games

I tried adding different configChanges and sure enough, "navigation" worked! Now bluetooth controllers hot-plug nicely. So shall we add it as a default to the AndroidManifest.xml?

Funny that this is how this activity is described:

	"navigation" The navigation type (trackball/dpad) has changed. (This should never normally happen.)

I think the reason behind this is because the bluetooth game controller I was testing doubles-up as a keyboard, which probably comes with a DPAD? It's a MOCUTE-032X_B63-88CE

Sam Lantinga 9950271bb6 Fixed bug 4580 - Android 8: immersive fullscreen notification causes flickering between fullscreen and non-fullscreen and app is unresponsive
Sylvain 2019-04-18 21:22:59 UTC

Changes:
- SDL_WINDOWEVENT_FOCUS_GAINED and SDL_WINDOWEVENT_FOCUS_LOST are sent when the java method onWindowFocusChanged() is called.

- If we have support for MultiWindow (eg API >= 24), SDL event loop is blocked/un-blocked (or simply egl-backed-up or not), when java onStart()/onStop() are called.

- If not, this behaves like now, SDL event loop is blocked/un-blocked when onPause()/onResume() are called.

So if we have two app on screen and switch from one to the other, only FOCUS events are sent (and onPause()/onResume() are called but empty. onStart()/onStop() are not called).
The SDL app, un-focused, would still continue to run and display frames (currently the App would be displayed, but paused).
Like a video player app or a chronometer that would still be refreshed, even if the window hasn't the focus.
It should work also on ChromeBooks (not tested), with two apps opened at the same time.


I am not sure this fix Dan's issue. Because focus lost event triggers Minimize function (which BTW is not provided on android).
https://hg.libsdl.org/SDL/file/bb41b3635c34/src/video/SDL_video.c#l2653
https://hg.libsdl.org/SDL/file/bb41b3635c34/src/video/SDL_video.c#l2634

So, in addition, it would need to add by default SDL_HINT_VIDEO_MINIMIZE_ON_FOCUS_LOSS to 0.
So that the lost focus event doesn't try to minimize the window. And this should fix also the issue.

Sylvain Becker dc263450ff Android: create Pause/ResumeSem semaphore at higher level than CreateWindow()
- 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.

Default launch mode (standard) allows multiple instances of the SDLActivity.
( https://developer.android.com/guide/topics/manifest/activity-element#lmode )

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
