Question

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

Answer 1

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.
