Notify users paid version of app is available

I am launching a paid version of my app. I want to notify the current users of the paid version being available now. How do I give a one time notification to the users about it. The only constraint is that this alert/notification should be launched only once. In C, I would have done it using static variable. Here should I do it onCreate? But if app is killed by the OS, the next time app starts onCreate would be called and that would result in the same notification again.

You need to use SharedPreferences, see following code:

@Override
protected void onCreate(Bundle savedInstanceState) {
   ...
   SharedPreferences prefs = PreferenceManager.getDefaultPreferences(this);
   if(prefs.getBoolean("not_notified", true))
   {
       //display alert
       prefs.edit().putBoolean("not_notified", false).commit();
   }
