Limit Android user location in city perimeters

Limit Android user location in city perimeters

I am creating an application where I need to apply borders at the user's location (Lat, Lng) to be in urban perimeters such as Uber. How can I achieve this?

This is the one when in the perimeters of the city

This is not in an urban or Uber service area.

I tried this approach. I use a geocoder and select the location address and the corresponding city parameters.

        addresses = geocoder.getFromLocation(lat, lon, 1); 
        if (addresses != null && !addresses.isEmpty()) {
            String address = addresses.get(0).getAddressLine(0);
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName();
        }
