Restart application on preference changed

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

If it's still useful for you: restart an app with AlarmManager:

AlarmManager alm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
    alm.set(AlarmManager.RTC, System.currentTimeMillis() + 1000, PendingIntent.getActivity(this, 0, new Intent(this, myActivity.class), 0));
    Process.killProcess(Process.myPid());

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.
