onSaveInstanceState () and onRestoreInstanceState ()

Question

I\'m trying to save and restore the state of an Activity using the methods onSaveInstanceState() and onRestoreInstanceState().

Answer 1

The main thing is that if you don't store in onSaveInstanceState() then onRestoreInstanceState() will not be called. This is the main difference between restoreInstanceState() and onCreate(). Make sure you really store something. Most likely this is your problem.
