onRestoreInstanceState not called when screen wake up?

Question

I\'ve wrote all the needed code to save my Activity state (a simple form with EditText widgets) and restore it on phone rotation and it works great.

My problem is on

Answer 1

The onRestoreInstanceState method is called only if the activity process is killed(due to memory constraints or some other reasons) and then restored when it becomes visible again. On the phone rotation, the activity is killed and restored with different orientation so it will work. But on screen on/off it wouldn't be the case. The activity has not been destroyed so no need for restore
