Im trying to change this code to do reverse geocoding as well. Coordinates work fine. Im gettin the error: location cannot be resolved to a variable. This error is at this line of code:
List<Address> addresses = geocoder.getFromLocation(location.getLatitude,
location.getLongitude, 1);
My full code is:
