title: Intent to resume a previously paused activity (Called from a Notification)
body: <p>I'm developing an app which shows a notification to the user. The notification's objective is to make it easy to the user to return to the activity when the user is in another activity. I am using this code in my app to create and show the notification.</p>
  
  <pre><code>                    notification = new Notification(R.drawable.icon,
                              "Notify",
                              System.currentTimeMillis());
                      notification.setLatestEventInfo(this, "App name",
                              "App message",
                              PendingIntent.getActivity(
                                      this, 0,
                                      new Intent(this, Main.class),
                                      PendingIntent.FLAG_CANCEL_CURRENT));
                      notification.flags |= Notification.FLAG_ONGOING_EVENT;
                      nManager.notify(0, notification);
  </code></pre>
  
  <p>But when the user taps the notification starts a new instance of the same activity, instead of the one that the user was using before.</p>
  
  <p>I think this has something to do with PendingIntent but I can't find how to make that Intent to resume a previously paused instance of the activity instead of creating a new instance.</p>
  
  <p>Thanks.</p>
