title: Notification bring app to front without change activity
body: <p>I want to create notification that when it clicked will bring my app to front but without changing (reload or navigate out) the last activity that was shown.</p>
  
  <p>I tried:  </p>
  
  <pre><code>setContentIntent(PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT))
  </code></pre>
  
  <p>But in the new Android 4.3 the application brought to front, but its also start a new instance of <code>MainActivity</code>, and I don't want this.</p>
  
  <p>I want that my app will continue from the last activity that was shown.<br>
  How to do that?</p>
