Reverse geocoding Problem

Question

my below code doesn't give any result.

list_addr = gc.getFromLocation(latitude, longitude, 5);

even not returns null value...

it behaves like dumb.

give me solution for that.

what does it return ? what values are latitude and longitude ? — alshapton, Feb 25 '11 at 12:00
latitude = Double.parseDouble(latitude_edtxt.getText().toString()); longitude = Double.parseDouble(longitude_edtxt.getText().toString()); — LostGeek, Feb 25 '11 at 12:06

Geocoder.getFromLocations(double, double, int) either returns a result (even null is a result) or throws an exception.

Are you silently catching generic exceptions somewhere in your code?

Update:

Use this code and then check the logcat. It should give you a reason why this does not work:

    Geocoder gc = new Geocoder(getApplicationContext(), Locale.getDefault());
    try {
        List<Address> list_addr = gc.getFromLocation(40.0d, 10.0d, 5);
    } catch (IllegalArgumentException iae) {
        Log.e("Geocoder IllegalArgumentException exception: ", iae.getMessage());
    } catch (IOException ioe) {
        Log.e("Geocoder IOException exception: ", ioe.getMessage());
    }

Update2:

This turned out to be a bug in Emulator v2.2: Android; Geocoder, why do I get "the service is not available"?

And what do you do when you catch an exception? Silently ignore it? – Peter Knego Feb 25 '11 at 12:11
javadoc says: "The Geocoder query methods will return an empty list if there no backend service in the platform." http://developer.android.com/reference/android/location/Geocoder.html – Peter Knego Feb 25 '11 at 12:32
Also, Geocoder needs internet access. Did you request permission? – Peter Knego Feb 25 '11 at 12:34
@peter : yes i have requested for permission in menifest file. – LostGeek Feb 25 '11 at 12:40
i enter 23.03957 and 72.56600 – LostGeek Feb 25 '11 at 12:43
@peter : it returns null. and error is "service is not available" – LostGeek Feb 25 '11 at 12:54
If you are trying it on emulator 2.2, then it might be a bug: http://stackoverflow.com/questions/3619924/android-geocoder-why-do-i-get-the-service-is-not-available – Peter Knego Feb 25 '11 at 13:04

try this

List<Address> addresses = new Geocoder(MyActivity.this,Locale.getDefault()).getFromLocation(latitude, longitude, 1);
