title: GCM notification not working (GoogleCloudMessaging)
body: <p>I have a strange problem with GCM using <code>GoogleCloudMessaging</code>, where the notifications work at the beginning but somehow stop working after some time (roughly an hour or so).</p>
  
  <p>Another thing, whenever I register with <code>GoogleCloudMessaging.getInstance(context).register(SENDER_ID);</code> i get the call in the <code>onReceive()</code> of my '<code>WakefulBroadcastReceiver</code>' which contains <code>REGISTRATION_ID</code> in bundle extras. Is this a common thing and should I just ignore this?</p>
  
  <p>I have followed the tutorial from here <a href="https://developer.android.com/google/gcm/client.html" rel="nofollow">Implementing GCM client</a>.</p>
  
  <p><strong>EDIT:</strong> The problem was with a library called Localytics, which was also handling Push notifications. Nothing related to GCM setup.</p>
