Google Maps SDK for Android - Cost

My question is about the charge in the Google Maps API, I have the following code:

public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(latitud, longitud);
    Point point = mMap.getProjection().toScreenLocation(sydney);

    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney,16));
}

That returns a map with a marker and with a latitude and longitude that I'm assigning. My question is: Does it cost to do this?
