Hi, good tutorial. I had a bug while implementing OnInfoWindowClickListerner in my app.
When i click on the infoWindow when the app runs in emulator it works fine, but on the physical device it does not detect the click.
Here is my code http://stackoverflow.com/questions/30087975/googlemap-setoninfowindowclicklistener-does-not-work-on-physical-device

Could you take a look at it? suggest me why this is happening ?

Thanks
