title: Android GCM Registration fails with AUTHENTICATION_FAILED exception
body: <p>I'm Trying to register to GCM to use push notification.
  For most of the devices it works, and I can get the push notification with not problem, but on 2 devices, I get </p>
  
  <blockquote>
    <p>"IOException (@GoogleCloudMessaging:register:-1)
    {AUTHENTICATION_FAILED}"</p>
  </blockquote>
  
  <p>I don't understand why this happens, can someone advise?
  Thanks</p>
  
  <p><strong>EDIT:</strong>
  I've tested the account user-id and password and they are correct (and the gmail is synced) and the google play services is up to date</p>
