Mapview mobile data consumption

i am working with google maps v2 api in my applicaiton. i am using a mapview inside a fragment like this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

 this.mapMV.onCreate(savedInstanceState);

 this.mapMV.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap googleMap) {

          googleMap.getUiSettings().setMyLocationButtonEnabled(true);
          googleMap.setMyLocationEnabled(true);
          googleMap.getUiSettings().setRotateGesturesEnabled(false);
          googleMap.getUiSettings().setMapToolbarEnabled(false);
       }
   });
}

everything works fine until i start moving in longer distance. during car ride google maps downloads cca 1 MB / min (for one day it is 300-400MB) vs. few kB in IOs version of this application.

Is there some way to reduce this huge data consumption?

ok, problem solved, this is my mistake, "problem" was in api call developers.google.com/maps/documentation/roads/snap – jakub
