title: how to get the running coordinates of a map while panning the map in V2
body: <p>I want to get the running coordinates (of the center of the map) when a user pans the map .Is there any way to do so ? I successfully got the center coordinates using <code>mMap.getCameraPosition().target;</code> and I can also get the coordinates while the user taps ,but I have no idea on how to get the running coordinates while panning the map.</p>
  
  <p>I would like to know if there is a tutorial or code snippet available for this</p>
