I need to restart the application from PreferenceActivity on preference changed. I tried:

@Override
public void onSharedPreferenceChanged(SharedPreferences pref, String key) {
    System.exit(2);
}

but after restart settings are not saved. Any ideas of how to restart the app with preferences are saved?
Thanks in advance

    Instead of a System.exit(2); I would try a

      this.finish(); 
    

    finish() is the call to stop the activity.

    to start an activity you need an intent object

     Intent screenToBeShown = new Intent(myactivity.this, whateveractivityyouwant.class); 
     startActivity(screenToBeShown); 
    

    Hope this helps.
