Xamarin GCM push notification not working
<p>I'm following step by step, and exactly copying the code provided in the following tutorial:</p>

<p><a href="https://developer.xamarin.com/guides/cross-platform/application_fundamentals/notifications/android/remote_notifications_in_android/" rel="nofollow">https://developer.xamarin.com/guides/cross-platform/application_fundamentals/notifications/android/remote_notifications_in_android/</a></p>

<p>By the way, I'm replacing with my API KEY, I'm testing using usb debug, with my moto g, running cyanogenmod, with mashmallow.</p>

<p>I'm not able to get the push notifications, and I don't get any errors. Any clue on this?</p>

<p><strong>UPDATE</strong>
Here is the logcat. I have reading that sometimes this error is due a missing google-services.json, but it seeems to not be required by xamarin.</p>
