Android notifications

This is a work in progress. I don't think the light notification is working yet.

if (notifyVibrate){
   Notification notification = new Notification();                                 
   notification.vibrate = new long[] { 100, 250, 100, 500};
   nm.notify(NOTIFY_ID, notification);                               
}
if (notifyLight) {                       
   Notification notification = new Notification();
   notification.ledARGB = 0xFFFF5171;
   notification.ledOnMS = 100;
   notification.ledOffMS = 100;                               
   notification.flags = Notification.FLAG_SHOW_LIGHTS;
   nm.notify(NOTIFY_ID, notification);
}
if (notifyToast) {
   Toast toast = Toast.makeText(timer.this , R.string.notification_text, Toast.LENGTH_SHORT);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();                               
}
if (notifySound) {
   mp.play(timer.this, Settings.System.DEFAULT_NOTIFICATION_URI, false, AudioManager.STREAM_ALARM);                               
}
