onSaveInstanceState is meant to be used for application restarts. For instance when the user changes the orientation on the screen. You want a permanent storage solution for data that should persist the application being launched, stopped, killed, etc... For a more permanent solution like SharedPreferences, Internal/External Storage, or SQLite Databases. Here's the tutorial on Data Storage options.
