android GCM doesn't work

Question

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.

I run the application on the client side and I get the registration_id. some huge string, in this format which is below:

APA91bEgguwt98xLbivrXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXLxDalNoEktCSVbOkT0-uFH2FaRnfpkRME2tzuvr0BycMNEhX_Ix1PV_XXXXXXXXXXXXXXXXXXXXXN5hcseY_wA.

This proves me that the client application works. Now the server (java, google example):

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();
        }
}

This is the server. When I run the server I got as result something like this: [ messageId=0:1341907115903155%921c249a00000031 ] 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?

I need help to understand what is wrong?

Note: If your organization has a firewall that restricts the traffic to or from the Internet, you'll need to configure it to allow connectivity with GCM. The ports to open are: 5228, 5229, and 5230. GCM typically only uses 5228, but it sometimes uses 5229 and 5230. GCM doesn't provide specific IPs. It changes IPs frequently.
