Android onRestoreInstanceState (Bundle savedInstanceState)

Question

 In my application, during normal operation, the onRestoreInstanceStatance function executes and throws a null pointer exception in any listener without calling this listener. My application contains a lot of data, which I write to a file in onPause and restore in onResume and onRestoreInstanceStatance. How can I make the application stable?

Answer 1

Be sure to assign listeners at the end onResume, which ensures that the listeners are not fired before the initial state is established. Then onPauseyou first need to remove the listeners.
