title: Android Pending intent started from notification doesn't replace the last
body: <p>I've read many posts on the same topic and tried all the given solutions without getting the result I want.
  The program should start an intent with extras from a notification:</p>
  
  <pre><code>NotificationManager mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);  
  
  Intent notificationIntent = new Intent(context, myActivity.class);
      notificationIntent.putExtra("someData", data);
  
  PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
  
  notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
  
  mNotificationManager.notify(ID, notification);
  </code></pre>
  
  <p>The problem is that when a new notification is shown, the extras added to the intent is the same as in the first notification. I've triend with differnt flags in both the intent and the pending intent, without result. What am I getting wrong?
  If i just launch the same activity (and the same extras) with a button, everything works as it's supposed to.</p>
