error in geocoder class in android

Question

    Geocoder gc = new Geocoder(this); 

     try {
    List<Address> foundAdresses = gc.getFromLocationName(addressInput, 5); //Search addresses
                        for (int i = 0; i < foundAdresses.size(); ++i) {
                          //Save results as Longitude and Latitude
                          //@todo: if more than one result, then show a select-list
                          Address x = foundAdresses.get(i);
                          double lat = x.getLatitude();
                          double lon = x.getLongitude();
                          Log.v("lat",""+lat);
                          Log.v("lon",""+lon);
                        } 
                    }
                    catch (Exception e) {
