Question

I am working on GPS system for android. I am able to find the latitude and longitude of my current position, but when I try to convert my latitude and longitude into Physical address my code doesn’t work. I have tried several possibilities. I have posted my code here.

Any help is much appreciated.
Thanks.

try {

        List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
        System.out.println(""+latitude);
        StringBuilder sb = new StringBuilder();
        if (addresses.size() > 0) {

        Address address = addresses.get(0);
        for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
        sb.append(address.getAddressLine(i)).append("\n");
        sb.append(address.getLocality()).append("\n");
        sb.append(address.getPostalCode()).append("\n");
        sb.append(address.getCountryName());
        }
        addressString = sb.toString();
        } catch (IOException e) {}
        } else {
        latLongString = "No location found";
        }
        myLocationText.setText("Your Current Position is:\n" +
        latLongString + "\n" + addressString);
        }

My problem is, I couldn’t get any value in the List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
. It returns a empty list only.
Could anyone tell me what the problem is and how to sort it out…

Geocoder gc = new Geocoder(ctx, Locale.getDefault());
List<Address> addresses;
addresses = gc.getFromLocation(lat, lng, 1);        
StringBuilder sb = new StringBuilder();
if (addresses.size() > 0) 
{
    Address address = addresses.get(0);
    for (int i = 0; i < address.getMaxAddressLineIndex(); i++)
         sb.append(address.getAddressLine(i)).append(",");
}

This would get a location. But sometimes an exception comes as "Unable to parse the response from server". You need to handle the exception.Also check for the INTERNET permission in the manifest.
