(Android) Big changes -
- both MainMenuActivity and RetroActivity are single instances now
- AKEYCODE_BACK gets eaten and onBackPressed in Java is triggered
- onBackPressed right now calls an instance of MainMenuActivity
(reuses the existing activity on the stack)
- User can switch back and forth between RetroActivity and MainMenuActivity
with AKEYCODE_BACK / Back button
- When a subsequent intent is launched after RetroActivity has already been
started up once, the pending intent gets passed to the existing RetroActivity
throug onNewIntent - in C land it will look every frame if an intent is pending - if it is, it will look up certain variables through JNI to launch a new game - or whatever it is that the intent wants to do
- With this we can now switch seamlessly between Android UI and RetroArch
itself.
