title: Android 4: can't dismiss notification by swiping
body: <p>I have some code that creates some notifications, it's really basic.</p>
  
  <pre><code>int icon = R.drawable.notification;
  CharSequence tickerText = "Text";
  long when = System.currentTimeMillis();
  Notification notification = new Notification(icon, tickerText, when);
  
  Context context = getApplicationContext();
  CharSequence contentTitle = "Text";
  CharSequence contentText = "Text";
  Intent notificationIntent = new Intent(this, RequestActivity.class);
  PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
  
  notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
  notification.flags |= Notification.DEFAULT_SOUND;
  notification.flags |= Notification.DEFAULT_VIBRATE;
  notification.flags |= Notification.DEFAULT_LIGHTS;
  notification.flags |= Notification.FLAG_AUTO_CANCEL;
  
  mNotificationManager.notify(notificationID, notification);
  </code></pre>
  
  <p>It all works fine in 2.1. 
  In 4.0, it all works fine except the swipe-to-dismiss action doesn't work. The notification goes slightly to the side then sticks and bounces back.
  Any idea?
  Thanks.</p>
