title: android GCM doesn't work
body: <p>I use the example provided by goole and I built an client side application to get notifications and a server side, both applications (code) is those provided by google. </p>
  
  <p>I run the application on the client side and I get the registration_id. some huge string, in this format which is below: </p>
  
  <p><code>APA91bEgguwt98xLbivrXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLxDalNoEktCSVbOkT0-uFH2FaRnfpkRME2tzuvr0BycMNEhX_Ix1PV_XXXXXXXXXXXXXXXXXXXXXN5hcseY_wA</code>. </p>
  
  <p>This proves me that the client application works. Now the server (java, google example):</p>
  
  <pre><code>public static void main(String[] args) {
  
          Sender sender = new Sender("AIzaSXXXXXXXXXX_XXXXXXXXXXXXXXXrQOnoGZw");      
          Message message = new Message.Builder()
          .collapseKey("1")
          .timeToLive(3)
          .delayWhileIdle(true)
          .addData("message",
            "this text will be seen in notification bar!!")
          .build();
  
          try {
              Result result = sender.send(message, "APA91bEgguwt98xLbivrXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLxDalNoEktCSVbOkT0-uFH2FaRnfpkRME2tzuvr0BycMNEhX_Ix1PV_XXXXXXXXXXXXXXXXXXXXXN5hcseY_wA", 3);
              System.out.println(result.toString());
          } catch (IOException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
  }
  </code></pre>
  
  <p>This is the server. When I run the server I got as result something like this: 
  <strong>[ messageId=0:1341907115903155%921c249a00000031 ]</strong>
  but no message on the client and I don't understand why. What is the meaning of the response I got from server? Is it the success response? </p>
  
  <p>I need help to understand what is wrong?</p>
