title: Android - notification, device not waking up, no sound or vibration
body: <p>I am trying to create a notification for my app that wakes up the device, plays a sound and vibrates. Following is the code that I am using. I found several such question in SO and tried the code in them. But the notification is still not waking up the device, there is no sound or vibration. The notification is showing up alright. Can anyone help me figure out what is wrong with the code?</p>
  
  <pre><code>Android.Net.Uri alarmSound = RingtoneManager.GetDefaultUri(RingtoneType.Notification);
  NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
              .SetAutoCancel(true) 
              .SetContentIntent(resultPendingIntent) 
              .SetContentTitle("Title")
              .SetSmallIcon(Resource.Drawable.Icon) 
              .SetContentText(String.Format("Message!"));
          Notification notification =builder.Build();
          notification.Sound = alarmSound;
          notification.Defaults = NotificationDefaults.Sound| NotificationDefaults.Vibrate | NotificationDefaults.Lights;
          NotificationManager nManager = (NotificationManager)GetSystemService(Context.NotificationService);
          nManager.Notify(0, notification);
  </code></pre>
