You can call Broadcast receiver in activity where u want to Display or pop up message like toast .below code do same

1) Modify onRegistered () method below

protected void onRegistered(Context context, String registrationId) 
{
        Log.i(TAG, "Device registered: regId = " + registrationId);
        GCMRegistrar.setRegisteredOnServer(context, true);
        CommonUtilities.displayMessage(context,registrationId);
}

2) Change displayMessage() of common util like below

static void displayMessage (Context context, String message,String senderID,String recieverId,String Type) 

{
            Intent intent = new Intent(DISPLAY_MESSAGE_ACTION);
            intent.putExtra(EXTRA_MESSAGE, message);
            context.sendBroadcast(intent);
}

3) on Main activity write we make Boradcaste receiver which notify user when application registered with gcm put below code in mainactivity or where u want to display popup

    @Override
        protected void onResume() {

            registerReceiver(mHandleMessageReceiver, new IntentFilter(
                    CommonUtilities.DISPLAY_MESSAGE_ACTION));

        }

    private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) 
            {
                        // you pop message display here when app. will get registered
Toast.makeText(context,getIntent().getExtras().getString(CommonUtilities.EXTRA_MESSAGE), 2).show();

            }
        };

    @Override
        protected void onStop() {
            // TODO Auto-generated method stub
            super.onPause();
            relaseMemory();
        }

Settings.Secure#ANDROID_ID returns the Android ID as an unique 64-bit hex string.

import android.provider.Settings.Secure;

private String android_id = Secure.getString(getContext().getContentResolver(),
                                                        Secure.ANDROID_ID); 

android_id contains the device id.

As a sample I have added the change only to the registerInGCMService() method.

public class GCMIntenetService extends GCMBaseIntentService {
    private static String GCM_SENDER_ID ;

    public GCMIntenetService() {
        super();
    }



    public static void registerInGCMService(Context context) {


         GCM_SENDER_ID =  Secure.getString(getContext().getContentResolver(),
                                                            Secure.ANDROID_ID); 

        if (!checkIsGCMServiceAvailable(context)) {
            return;
        }
        final String regId = GCMRegistrar.getRegistrationId(context);
        if (regId.equals("")) {
            try {
                GCMRegistrar.register(context, GCM_SENDER_ID);
            } catch (Exception ex) {
            }
        } else {
            // Already registered
        }
    }



}
