I have a reciever that works well, but I can't seem to show a proper UI, although the toast appears correctly. As far as I can tell, this is caused by Android requiring the class to extend Activity, however, the class already extends BroadcastReciever, so I can't do this. So, I tried to do an Intent, but this failed too. There are no errors, but the screen doesn't show. Source code is below, and any help would be most appreciated.

Reciever

public class Reciever extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Toast.makeText(context, "Alarm Recieved", Toast.LENGTH_LONG).show();
        Intent i = new Intent();
        i.setClass(context, AlarmRing.class);
    }
}

AlarmRing

public class AlarmRing extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.alarm);

        MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.sweetchild);
        mp.start();
    }
