it will be enough to show me Java source of saving one boolean variable, and restore it,
Thanks.

    I would use onPause(), as onStop() is not guaranteed to be called. See the application fundamentals for details on the lifecycle.

    To save and restore a boolean, I would use SharedPreferences. There is a code example on the data storage page that shows how to save and restore a boolean. They use onCreate() and onStop(), but I would use onResume() and onPause(), for the reasons I have already mentioned.
