        That is the reason, I have the same issue. Just make checkSelfPermission and see if that works. if not you must realize that code can't work in your api. here

                    My problem is solved. The blue screen representing ocean. so i have changed 'mMap.moveCamera(CameraUpdateFactory.newLatLng(hyderabad));mMap.moveCamera(CameraUpdateFactory.zoomTo(12));' to 'mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(hyderabad,12.0f));'. Now map showing my Hyderabad 'LatLng hyderabad = new LatLng(17.3850,78.4867);'. But my logcat is filled with 'W/Google Maps Android API: GLHudOverlay deprecated; draw(): no-op'. This issue will be solved by google play services for the next release [https://code.google.com/p/gmaps-api-issues/issues/detail?id=10201]. Thank you – Charan Reddy Aug 30 '16 at 10:15
