Android: ContentObserver not working in android 4.3

ContentObserver works fine in android 4.0.4 where it detects changes made in settings app. But when under android 4.3 it doesnt detect the change and the service doesnt start

SettingsContentObserver.java:

public class SettingsContentObserver extends ContentObserver
{

private Context context;


public SettingsContentObserver(Handler handler, Context applicationContext) {
    // TODO Auto-generated constructor stub
    super(handler);
    this.context = applicationContext;
}

@Override
public boolean deliverSelfNotifications()
{
    return super.deliverSelfNotifications();
}

@Override
public void onChange(boolean selfChange)
{
    super.onChange(selfChange);

  System.out.println("Change detected");
  Intent i = new Intent(context, MyService.class);
  context.startService(i);
}



}

MyService.java:

public void onCreate() {
 SettingsContentObserver mSettingsContentObserver = new SettingsContentObserver(new Handler(), getApplicationContext());
        getApplicationContext().getContentResolver().registerContentObserver(android.provider.Settings.System.CONTENT_URI, true, mSettingsContentObserver);
    System.out.println("Observer registered");
}

public void onStart(Intent intent, int startId) {
            System.out.println("Service works");

}

Thanks, Sahil

Some of these settings have been moved to Settings.Global as of Android 4.2 - so listen to the content Uri provided there as well.
