                    // 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. 
                    // Persist the regID - no need to register again.

                    // If there is an error, don't just keep trying to register.
