- 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.
* pthread_key_create is used to set a destructor for every thread
created through jni_thread_getenv
* To grab a JNIEnv pointer - go through jni_thread_getenv
* jni_thread_getenv sets pthread_setspecific for the JNIEnv pointer
to bind destructor
* Reuse activity->vm everywhere instead of creating local pointer
copies
* Don't use DetachCurrentThread outside of platform_android's (new)
jni_thread_destruct function - the destructor will do this for us
now
