Hers’s The Class

package com.example.test09_gsm;

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


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

    public GCMIntentService(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));
    }

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

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

Main Activity

package com.example.test09_gsm;

import com.google.android.gcm.GCMRegistrar;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        GCMRegistrar.checkDevice(this);
        GCMRegistrar.checkManifest(this);
        final String regId = GCMRegistrar.getRegistrationId(this);
        if (regId.equals(""))
        {
          GCMRegistrar.register(this, "XXXXXXXXXXXX");
        }
        else
        {
          Log.v("Info : ", "Already registered");
        }

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

Answer 1

try after adding default constructor to GCMIntentService as :

public GCMIntentService() {
        super("IntentService");
    }
