Android onRestoreInstanceState(Bundle savedInstanceState)

Question

In my application during normal operation the onRestoreInstanceStatance function is executed and causes a null pointer exception in some listener, without invoking that listener. My app contains a lot of data that I write to a file in onPause and restore in onResume and onRestoreInstanceStatance. How can I make the app stable?

Answer 1

Make sure you assign listeners in the end of the onResume , that will ensure no listeners are fired BEFORE the initial state is set. Then in onPause first thing to do is to remove listeners.
