Xamarin Forms Push Notification

Hi,

I have used this plugin for push notification in Xamarin.Forms
https://github.com/rdelrosario/xamarin-plugins/tree/master/PushNotification

i am able to register and i got Token and device type but i am unable to receive a notification

   void IPushNotificationListener.OnMessage(JObject values, DeviceType deviceType)
        {
            Debug.WriteLine("Message Arrived");
        }

        //Gets the registration token after push registration
        void IPushNotificationListener.OnRegistered(string Token, DeviceType deviceType)
        {
            Debug.WriteLine(string.Format("Push Notification - Device Registered - Token : {0}", Token));
        }

Please help me find a fix!
