title: Device is not getting registered on GCM for push messages
body: <p>I have build android application with GCM feature for push messages.
  I have 3 devices to test but one of my device is not getting registered. The device that is not getting registered is TAB with Android 4.4.2  Devices that are getting registered are smart phone, one with Android 2.3.6 and on with Android 4.0.4</p>
  
  <p>Following is my log generated for TAB which is not getting registered.</p>
  
  <pre><code>12-17 10:39:30.583: W/GCM(15943): GCM FAILED TO INITIALIZE - missing checkin
  12-17 10:39:30.583: W/GCM(15943): GCM registration failed: invalid or missing checkin null
  12-17 10:39:30.593: E/GCM(15943): GCM failed to read backup checkin config, checkin may have failed
  </code></pre>
  
  <p>Can you please help me find out why this is happening and what is the solution. My bad, that is the device of my boss and i have to show demo on that device.</p>
  
  <p>Thanks..</p>
