Answer 1

reference

onSaveInstanceState

... onPause()-> onSaveInstanceState() -> onStop() -> onDestory()

onCreate()-> onStart()-> onRestoreInstanceState()-> onPostCreate(Bundle) ...

Or You can use LiveData. Save the states in it and observe.If the device rotates it'll update the views accordingly.
