I have created my Android app to get Registration Id from GCM and receive a downstream notification. Registration part is working perfectly here. (RegID is sent to me by opening an email and I'm hard coding it in my 3rd party server.) But the thing is when I send a message from my server my app never receives it. Following is my Code.
NotificationMainActivity - (Registers the app in GCM successfully)
public class NotificationMainActivity extends Activity {
public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";

// Check device for Play Services APK. If check succeeds, proceed with
// GCM registration.
if (checkPlayServices()) {
