title: Android, the onLongPress event and zooming are mixed up
body: <p>Good evening, 
  please I have the same question already asked but not answered,(<a href="https://stackoverflow.com/q/7311639/2969783">Android MapActivity onLongPress / zooming mix up</a>)</p>
  
  <p>this is the question :</p>
  
  <p>I have a class extending <code>MapActivity</code> which has an overlay attached to it extending <code>ItemizedOverlay</code>. Inside the overlay I have a <code>GestureDetector</code> and a <code>OnGestureListener</code>. Now for my problem:</p>
  
  <p>I have an action which triggers in the <code>onLongPress</code> of the <code>OnGestureListener</code> but Android triggers this even when you zoom in / out using the "pinch" gesture. This is maibe due to the fact that one finger tends to stay in one spot while the other one moves towards / away. What kind of calls or checks could be implemented to detect whether the action is a pinch-zoom or a <code>longPress</code>, so I know to either handle or disregard in onLongPress?</p>
  
  <p>thank you.</p>
