title: Android GCM onMessage
body: <p>I try to implement GCM in my project and have problems with onMessage function. According to the examples, I write:</p>
  
  <pre><code>@Override
  protected void onMessage(Context arg0, Intent arg1) {
  // TODO Auto-generated method stub
  Log.d("GCM", "RECIEVED A MESSAGE: " + arg1.getStringExtra("message"));
  // other part of the code goes here...
  }
  </code></pre>
  
  <p>Well, and I get errors with this getStringExtra - it seems this intent doesn't contain it. I do receive onMessage event, that's for sure. I just get errors when try to get actual message.
  My server receives:</p>
  
  <pre><code>{"multicast_id":7888157947681629492,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1348246306435688%196553bef9fd7ecd"}]}
  </code></pre>
