How to use Android studio Ringtonemanager.TYPE_RINGTONE

Question

I need to sound an alarm ringtone after a layout popup with a stop button... I had use if else, if (usenotification), I'm able to make a ringtone sounds

but in else (), it doesn't work..

This is my code:

public class AlarmActivity extends Activity {

    Uri uriRingtone;
    Ringtone ringTone;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.alarm);

        uriRingtone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);

        Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
        if (alarmSound == null) {
            ringTone = RingtoneManager
                .getRingtone(getApplicationContext(), uriRingtone);
        }

       uriRingtone = alarmSound;
    }
}

*the if part works... only else doesnt... // another part of java

public class OnAlarmReceiver extends BroadcastReceiver {
    private static final int NOTIFY_ME_ID = 1337;

    Uri uriRingtone;
    Ringtone ringTone;

    @Override
    public void onReceive(Context ctxt, Intent intent) {
        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(ctxt);
        boolean useNotification = prefs.getBoolean("use_notification", true);
        if (useNotification) {
            NotificationManager mgr = (NotificationManager) ctxt
                    .getSystemService(Context.NOTIFICATION_SERVICE);
            Notification note = new Notification(R.drawable.stat_notify_chat, "It's Lunch time!", System.currentTimeMillis());
            PendingIntent i = PendingIntent.getActivity(ctxt, 0, new Intent(ctxt, AlarmActivity.class), 0);

            note.setLatestEventInfo(ctxt, "Lunch!", i);
            Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
            if(alarmSound == null){
                alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);

            }
            note.sound = alarmSound;
            note.flags |= Notification.FLAG_AUTO_CANCEL;
            mgr.notify(NOTIFY_ME_ID, note);

        } else {

            Intent i = new Intent(ctxt, AlarmActivity.class);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            ctxt.startActivity(i);

        }
    }
}
