title: How to manage InfoWindows for polygons on Android Google Maps API v2
body: <p>I'm looking for a way to manage Info Windows (open, close, set content) for polygons, just like it's done for markers<br>
  I can probably listen for onClick event and put a some hidden marker there and open an InfoWindow for that marker. There is a problem finding a polygon to retrieve an InfoWindow content though.<br>
  There is a more elegant solution?</p>
