So I have log messages that get displayed whenever onPause, onStop, and onDestroy get called.
I don't actually save my preferences in any of these methods, I save them when the values get changed by the user. By watching the logcat messages I have determined that my preferences get deleted (do not persist) only when the onDestroy() method is called but when onStop is called the preferences load perfectly fine the next time my activity starts.
