title: How to handle onTouch event for map in Google Map API v2?
body: <p>GoogleMap by default doesn't provide event for map drag start and drag stop. <a href="https://stackoverflow.com/questions/13702117/how-can-i-handle-map-move-end-using-google-maps-for-android-v2">I have already reported that problem here</a>.</p>
  
  <p>I want to make <strong>custom</strong> <code>handler</code> that will use plain <code>onTouch</code> event and combine it with <code>setOnCameraChangeListener</code>.</p>
  
  <p>However i failed to find how I can access <code>onTouch</code> event of <code>GoogleMap</code> object. It doesn't provide such <strong>callback</strong>.</p>
  
  <p>I wonder how can i handle onTouch event for map  in <strong>Google Map API v2</strong>?</p>
