title: how can i implement my own double-tap in mapview?
body: <p>I have been working on an offline map using <a href="http://code.google.com/p/osmdroid/" rel="nofollow">OSMdroid</a></p>
  
  <p>I have map tiles of two zoom levels namely 12 and 15</p>
  
  <p>Now the usual double tap zooms the mapview by 1 level</p>
  
  <p>What i m trying to do is to <code>setZoomLevel()</code> as 15 after the user double taps on the map,</p>
  
  <p>Is it possible?</p>
  
  <p>I tried using <code>onGestureListener</code> , but somehow it is not working</p>
  
  <p>Any hint or clues in that direction or sample codes would be a big help , Thanks</p>
