Question

I’m developing an app which needs to rotate the mapView with a compass. I know how to rotate the camera but I need to rotate the mapView with the compass. the center point should be the current location. I found codes for Maps V1 but I need to do it with Maps V2

Answer 1

OK, i figured it out myself. first you need to calculate the bearing from the compass.
then the Maps api-2 camera can be rotated.

public void updateCamera(float bearing) {
            CameraPosition currentPlace = new CameraPosition.Builder()
                    .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.
