                    .target(new LatLng(centerLatitude, centerLongitude))
                    .bearing(bearing).tilt(65.5f).zoom(18f).build();
            googleMap.moveCamera(CameraUpdateFactory.newCameraPosition(currentPlace));

    }

set SensorListener in your code and call this method in onSensorChanged event. i have added a tilt value so the map will rotate in 3D.
