Android :Tap on Push Notification does not open Ap

I have an android app which requires some notifications from my web-server to my android phone . Earlier I used to receive notifications and on tapping the notification , my application used to open . However without anything being changed now , I receive all notifications but I cannot tap on them to open my application anymore .

I have tried checking the code and the manifest for permissions , but dosen't seem to know the problem .

Here are some of the required code files :

GcmIntentService.java

package com.rakibansary.roomautomator.services;

import android.app.IntentService;
import android.content.Intent;

/**
 * Created by rakib on 5/10/15.
 */
public class GcmIntentService extends IntentService {

    public GcmIntentService() {
        super("GcmIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {

    }
}

You may add a Intent to your notification to make it happen.

In your GcmBroadcastReceiver.java between NotificationManager mNotifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); and mNotifyMgr.notify(224, mBuilder.build());

You should add following code:

Notification notification = mBuilder.build();
Intent notificationIntent = new Intent(context, MainActivity.class);

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP);

PendingIntent intent = PendingIntent.getActivity(context, 0,
                notificationIntent, 0);

notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
