     private void updateWithNewLocation(Location location) {
    TextView myLocationText;
    myLocationText = (TextView)findViewById(R.id.myLocationText);

    String latLongString = "No location found";
    String addressString = "No address found";

    if (location != null) {
      double lat = location.getLatitude();
      double lng = location.getLongitude();
      latLongString = "Lat:" + lat + "\nLong:" + lng;

      double latitude = location.getLatitude();
      double longitude = location.getLongitude();
      Geocoder gc = new Geocoder(this, Locale.getDefault());

      try {
        List<Address> addresses = gc.getFromLocation(latitude, longitude, 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("\n");

          sb.append(address.getLocality()).append("\n");
          sb.append(address.getPostalCode()).append("\n");
          sb.append(address.getCountryName());
        }
        addressString = sb.toString();
      } catch (IOException e) {}
    }

    myLocationText.setText("Your Current Position is:\n" +
                            latLongString + "\n\n" + addressString);
  }

  private final LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      updateWithNewLocation(location);
    }
