Push notification is not coming when the app clean(remove) from the task manager ?

Question

In my app i am using push notification.it is working fine.but when i remove(clean) the app from the task manager.the push notification is not arriving.what is the problem i don't know.If anyone know how can i resolve this.Please tell me.

This is the method by which i am sending the notification :-

private void sendNotification(String msg) {

        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);


        Intent intent = new Intent(this, MainActivity.class);

        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        Log.e("message.....", msg);


        if (msg.equals("You Have got New Message")) {

            Log.e("msg occuring..", "intent enter in message...");
            intent.putExtra("KEYMESSAGE", "Message");


        } else {

            Log.e("notification occuring..", "notification occurs.....");
            intent.putExtra("KEYNOTIFICATION", "aman");


        }




 PendingIntent  contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(getNotificationIcon())
                .setContentTitle("Telepoh")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg)
                .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);

        mBuilder.setContentIntent(contentIntent);
        mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
        mBuilder.getNotification().flags |= Notification.FLAG_ONGOING_EVENT;
        mBuilder.setOngoing(false);

        mBuilder.setAutoCancel(true);


        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());


    }

My problem is Notification is coming properly when the app in the running state.but when the app remove(Clean) from the task manager the notification is not arriving.Please if anyone know what is the problem.then please tell me.

Replace this line with

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

this one

intent.addFlags(FLAG_INCLUDE_STOPPED_PACKAGES|Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

Edited:

As per Android guide lines Once App will be force closed , then all services ,receivers and alarm are destroyed so in that case you will not get any notifications

@ Mohit Trivedi as per your edited answer. there is no chance to get the notification when app kills from the task manager.then how can the whatsapp is working. in whatsapp when we clean the app from the task manager the notification will come. – aarav Oct 01 '16 at 11:00

Push notification is a message pushed from the server to the client. Their must be some service in your app running in the background so that your can always entertain your message.

In my opinion please go with Firebase Cloud Messaging. For complete tutorial and code refer below:
