title: I am not getting google maps onTouchEvent events
body: <p>I am trying to learn about Google maps API.  I have a project that shows the map, sets coordinates and does zoom in and out. I am trying to add an onTouch event.  I have:</p>
  
  <pre><code>class MapOverlay extends com.google.android.maps.Overlay {...}
  </code></pre>
  
  <p>and added</p>
  
  <pre><code>public boolean onTouchEvent(android.view.MotionEvent event, MapView mapView)
  </code></pre>
  
  <p>All seems fine but the <code>onTouchEvent</code> is never called.  What am I missing?</p>
