AppState does not call 'change' event when entering PiP if using Android's `setAutoEnterEnabled` param for PiP

[sweatherall]

Description

For Android 12, the newly suggested configuration for PiP is to use setAutoEnterEnabled [docs] instead of manually calling enterPictureInPictureMode within MainActivity.java onUserLeaveHint

However, when using setAutoEnterEnabled, although it successfully enters PiP mode, it does not trigger a change event for AppState (AppState.addEventListener('change', ...))

This results in react native not being aware that the app is in background while in PiP, and instead the AppState stays active

Steps to reproduce

• Init PiP for Android following these steps
• Add AppState listener for change event in react native code
• Put react native app into PiP mode, notice that it does not trigger the AppState change callback

Snack, code example, screenshot, or link to a repository

AppState listener for RN code:

const appStateListener = AppState.addEventListener('change', (nextAppState) => {
    console .log('AppState change; Next app state: ', nextAppState);
});

Add this to MainActivity.java to init PiP:

@Override
  protected void onStart() {
    super.onStart();
    new PictureInPictureParams.Builder()
        .setAspectRatio(new Rational(3, 4))
        .setSeamlessResizeEnabled(false)
        .setAutoEnterEnabled(true)
        .build();
}
