title: Remove notification after clicking
body: <p>I want that the notification will be closed after the user is clicking on it. I saw that everybody saying to use flags, but I can't find the flags anywhere because I'm using NotificationCompat.Builder class and not Notification class. Someone have any idea how to make the notification remove by her self?<br>
  Here is my code when I'm setting the notification: </p>
  
  <pre><code>NotificationCompat.Builder mBuilder =
              new NotificationCompat.Builder(this)
              .setSmallIcon(R.drawable.ic_launcher)
              .setContentTitle("New Question")
              .setContentText("" + QuestionData.getAuthor().getUserName() + ": " + QuestionData.getQuestion() + "");
  
      Intent openHomePageActivity = new Intent("com.example.ihelp.HOMEPAGEACTIVITY");
      TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
      stackBuilder.addNextIntent(openHomePageActivity);
  
      PendingIntent resultPendingIntent =
              stackBuilder.getPendingIntent(
                  0,
                  PendingIntent.FLAG_UPDATE_CURRENT
              );
      mBuilder.setContentIntent(resultPendingIntent);
      NotificationManager mNotificationManager =
          (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);       
  
      mNotificationManager.notify(0, mBuilder.build());
  </code></pre>
