I have followed one link which has the code to make map which we can drag and get the current location. Here is the link. How to Implement draggable map like uber android, Update with change location
I have followed all the code still I am unable to get the result. The map we can drag but not showing the location on text view.

mGoogleMap.setOnCameraChangeListenerwill be called, you need to check there for latlong and have to use geocoder to get address, Please check at that point if it is being called or not, right now. – Bisutun
