Code example for GoogleCloudMessaging

Methods: register

                String msg = "";

                    msg = "Device registered, registration id=" + regid;
                    // You should send the registration ID to your server over HTTP, 
                    // so it can use GCM/HTTP or CCS to send messages to your app. 
                    // For this demo: we don't need to send it because the device 
                    // will send upstream messages to a server that echo back the message 
                    // using the 'from' address in the message. 
                    // Save the regid - no need to register again. 
                    setRegistrationId(context, regid);
                } catch (IOException ex) {
                    msg = "Error :" + ex.getMessage();
