GCM广播接收器未触发

Question

I have looked at several questions on this site and none seem to be able to answer my question so hopefully someone can help with this. Currently for some reason when I send a message through from the PHP Website, my app doesn't receive the message. I have tried placing Log.d's in the lines of code but it doesn't appear as well. Can someone help to see if something has gone wrong?

[UPDATE] This is the result when I send from the php website {"multicast_id":5610818169388245295,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1460536959734990%40ad5721f9fd7ecd"}]}

My Broadcast Receiver

public class GCMBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    ComponentName comp = new ComponentName(context.getPackageName(), GCMNotificationIntentService.class.getName());
    startWakefulService(context, (intent.setComponent(comp)));
    Log.d("TESTTEST", "TEST");
    setResultCode(Activity.RESULT_OK);
}
}

My intent service

public class GCMNotificationIntentService extends IntentService{


//set ID for the notification, so it can be updated
public static final int notifyID = 9001;
NotificationCompat.Builder builder;
public GCMNotificationIntentService() {
    super("GCM Intent Service");
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);

    String messageType = gcm.getMessageType(intent);
    Log.d("RECEIVEDMESSAGE", messageType);

    if (!extras.isEmpty()) {
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                .equals(messageType)) {
            sendNotification("Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                .equals(messageType)) {
            sendNotification("Deleted messages on server: "
                    + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                .equals(messageType)) {
            sendNotification("Message Received from Google GCM Server:nn"
                    + extras.get(AppConstants.MSG_KEY));
        }
    }

    GCMBroadcastReceiver.completeWakefulIntent(intent);
}

private void sendNotification(String msg){

    Intent resultIntent = new Intent(this, HomeActivity.class);
    Log.d("RECEIVEDPT2",msg);
    resultIntent.putExtra("msg", msg);
    PendingIntent resultPendingIntent = PendingIntent.getActivity(this,0,resultIntent,PendingIntent.FLAG_ONE_SHOT);
    NotificationCompat.Builder mNotifyBuilder;
    NotificationManager mNotificationManager;

    mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    mNotifyBuilder = new NotificationCompat.Builder(this).setContentTitle("Alert")
            .setContentTitle("You've received a new message");

    //Set pending intent
    mNotifyBuilder.setContentIntent(resultPendingIntent);

    //Set vibration
    int defaults = 0;
    defaults = defaults | Notification.DEFAULT_LIGHTS;
    defaults = defaults | Notification.DEFAULT_VIBRATE;
    defaults = defaults | Notification.DEFAULT_SOUND;

    mNotifyBuilder.setDefaults(defaults);
    // Set the content for Notification
    mNotifyBuilder.setContentText("You have new notifications");
    // Set autocancel
    mNotifyBuilder.setAutoCancel(true);
    // Post a notification
    mNotificationManager.notify(notifyID, mNotifyBuilder.build());

}
}

Please help.
