Question

I am using GCM service on my new Android app , I did my code well but when I am running the project on my mobile I had exception that the project stopped unexpectedly , but when I commented this lines of code

 GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this); 

The error stopped but when I was running the project error occurred and when I checked my Google API to check if the error sent to my Google API but I didn’t find any reports why???

GCMIntenetService class

package com.example.elarabygroup;

import com.google.android.gcm.GCMBaseIntentService;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class GCMIntenetService extends GCMBaseIntentService {
    public static String TAG = "GCMIntentService";

    public GCMIntenetService(String senderId) {
        super(senderId);
        Log.d("GCMIntentService", senderId);
    }

    @Override
    protected void onError(Context arg0, String arg1) {
        Log.d("onError", arg1);
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        Log.d("onRecoverableError", errorId);
        return false;
    }

    @Override
    /*
    protected void onMessage(Context arg0, Intent arg1) {
        Log.d("onMessage", String.valueOf(arg1));
    }
    */
    protected void onMessage(Context arg0, Intent arg1) {

        Log.d("GCM", "RECIEVED A MESSAGE");
        // Get the data from intent and send to notificaion bar
        generateNotification(arg0, arg1.getStringExtra("**notificaion**"));
    }

    private void generateNotification(Context arg0, String stringExtra) {
        // TODO Auto-generated method stub

    }

    @Override
    protected void onRegistered(Context arg0, String arg1) {
        Log.d("onRegistered", arg1);
    }

    @Override
    protected void onUnregistered(Context arg0, String arg1) {
        Log.d("onUnregistered", arg1);
    }
}

If log is available We can find the problem, so try to get log by installing some application like aLogCat in your mobile.

if you can’t get that, Refer this tutorial
