Receive a message on a device with GCM

Question

Actually I am working on the notifications for an Android app. My two main source of information are this tutorial and the android developer web site.

Let me quickly describe my app:

• In my app I use web services (WS) which work with POST HTTP request.
• For the Notification I use the GCM system.
• My app uses the 'POST HTTP' request system above to be register on my server.
• Actually my server does exactly the same job as the one in the tutorial (that means to register an account in the database with to two parameters and the register ID of the device, and send a message to the device with GCM)

Actually all of these steps work:

1. My app receive successfully gets register ID (gcm.register(SENDER_ID); work)
2. My app get successfully registered on my server

3. My server receives a successful message when I try to send a message from my device

   {"multicast_id" : 6276079906208554309 , "success" : 1 , "failure" : 0 , "canonical_ids" : 0 , "results" : [{"message_id" : "0:1374826298092960%978fee92f9fd7ecd"}]}

The Problem:

• I receive nothing on my device

What I did:

I try to do two versions of the application:

• First I made an app using a part of the code of the tutorial, but with using the package com.google.android.gms.gcm.GoogleCloudMessaging instead of the com.google.android.gcm which are deprecated (and used in the tutorial), but I was unable to receive a message, so I try a second version …
• This time I took the entire tutorial and just change the register function on the server to use mine, but like the first app, I receive nothing on my device. (I did this to try to understand how work the reception but it did not help me, and now I will forget this way)

Where do I need your help:

I need some/more explanation how to receive the message sent by my server.

• My main activity uses the code describe on the android developer web site.
• I create a broadcast class using the code on the android developer web site.
• I don’t create any IntentService or service, maybe it is my error, but according what I read I understood that I don’t need one, like before with the deprecated GCMBaseIntentService

To conclude:

• I really will appreciate some help to understand what I need to receive the message on my device, because actually I don’t know where I can found the information I need to be able to use this system.

Thanks.

PS: if you need some part of my code , just ask me.

And my GcmBroadcastReceiver (who come from the tutorial)

the WakeLocker is the same as the tutorial too.

package com.androidhive.pushnotifications2;

import android.app.Activity;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;

import com.google.android.gms.gcm.GoogleCloudMessaging;

public class GcmBroadcastReceiver extends BroadcastReceiver {
    static final String TAG = "GCMDemo";
    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    NotificationCompat.Builder builder;
    Context ctx;
    @Override
    public void onReceive(Context context, Intent intent) {
        ///
        WakeLocker.acquire(context);
        ///
        System.out.println("TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT");
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);
        ctx = context;
        String messageType = gcm.getMessageType(intent);
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            sendNotification("Send error: " + intent.getExtras().toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server: " +
                    intent.getExtras().toString());
        } else {
            sendNotification("Received: " + intent.getExtras().toString());
        }
        WakeLocker.release();
        setResultCode(Activity.RESULT_OK);
    }

    // Put the GCM message into a notification and post it.
    private void sendNotification(String msg) {
        mNotificationManager = (NotificationManager)
                ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0,
                new Intent(ctx, MainActivity.class), 0);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(ctx)
        .setSmallIcon(R.drawable.common_signin_btn_icon_focus_light)
        .setContentTitle("GCM Notification")
        .setStyle(new NotificationCompat.BigTextStyle()
        .bigText(msg))
        .setContentText(msg);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }
}
