Restart the application when click on notification

Question

I am using following code to open my application when clicking on Notification

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

          PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
              i, PendingIntent.FLAG_UPDATE_CURRENT);      

          NotificationCompat.Builder mBuilder =
              new NotificationCompat.Builder(context)
              .setSmallIcon(R.drawable.ic_launcher)
              .setContentTitle(title)
              .setDefaults(Notification.DEFAULT_SOUND)
              .setStyle(new NotificationCompat.BigTextStyle()
                         .bigText(msg))
              .setContentText(msg);

         mBuilder.setContentIntent(contentIntent);
         mNotificationManager.cancel(Constants.PUSH_ID);
         mNotificationManager.notify(Constants.PUSH_ID, mBuilder.build());

The problem is, if the application is already running, it opens startup application after my current activity.

 Intent x = new Intent(context, MainActivity.class);
                                 i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                                 i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
                                 i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

How can i close the old and start the application new one.

You need to use an appropriate intent filter in your Android Manifest. — Michał Szydłowski, Feb 11 '15 at 12:55
well, i want it to restart the app. Instead of creating new activities check my edited code for my Intent — Muhammad Umar, Feb 11 '15 at 12:57
I reckon starting the application from where you left it is a better approach. — Tushar Gogna, Feb 11 '15 at 12:58
well, ok but atleast it shouldn't start the activities over top of other activities. e.g if i am at activity 2 and i click on notification, it will start splash on top of activity 2 and so on. I have to go back to clear this stack — Muhammad Umar, Feb 11 '15 at 12:58
Yes, I'm also facing the same problem. It brings the triggered activity on top. — Tushar Gogna, Feb 11 '15 at 13:00

OK, i found a very cool and simple solution. I would just pass an extra boolean to my intent like i.putExtra("shouldRestart", true);

on my SplashActivity, i check

if(getIntent().getBooleanExtra("shouldRestart", false))
{
   // we need to clear all activities from top 
   finishAffinity();
}
