http://stackoverflow.com – Somewhere in between the onCreate() and onPause() method, my changePage boolean gets changed from false to true without invoking any changes to it systematically. Once the onCreate() method is called, I press the home button which triggers the onPause() method and suddenly the boolean is changed to true.
