Help w/Remote Notifications

I have followed the Xamarin documentation here, http://docs.xamarin.com/guides/cross-platform/application_fundamentals/notifications/android/remote_notifications_in_android/, and my app still does not receive notifications. In my MainActivity, I create an intent to register for CCM notifications, but nothing happens . Just a note, I have been heavily engaged w/Xamarin.IOS and am now getting into the Android platform. Any assistance would be greatly appreciated. Thanks in advance to all that assist. Below is code from each of the required classes (as specified by documentation) to enable remote notifications:

********Permissions in the AndroidManafest.xml ' <?xml version="1.0" encoding="utf-8"?> '

********Intent to Register for GCM in MainActivity `string senders = "mysenderid"; Intent intent = new Intent("com.google.android.c2dm.intent.REGISTER");

        intent.SetPackage("com.google.android.gsf");
        intent.PutExtra("app", PendingIntent.GetBroadcast(this, 0, new Intent(), 0));
        intent.PutExtra("sender", senders);
        this.StartService(intent);`
