ResultReceiver.send throws nullpointerexception



I have searched for an answer but I couldn't find one. I am reverse geocoding latitude and latitude in IntentService then when I try to ResultReceiver.send it throws nullpointerexception. I debugged the arguments and they contain the address and the result code just like they are supposed to. I searched on any uninitialized objects but I couldn't fine one. Can anyone give me a clue on what's going on?


This is the method that reversegeocodes the lat and lon.



@Override
public void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
String errorMessage = "";

// Get the location passed to this service through an extra.
Location location = intent.getParcelableExtra(
Constants.LOCATION_DATA_EXTRA);

List<Address> addresses = null;

try {
addresses = geocoder.getFromLocation(
location.getLatitude(),
location.getLongitude(),
// In this sample, get just one addresse.
1);
} catch (IOException ioException) {
// Catch network or other I/O problems.
errorMessage = getString(R.string.service_not_available);
Log.e(TAG, errorMessage, ioException);
} catch (IllegalArgumentException illegalArgumentException) {
// Catch invalid latitude or longitude values.
errorMessage = getString(R.string.invalid_lat_lon);
Log.e(TAG, errorMessage + ". " +
"Latitude = " + location.getLatitude() +
", Longitude = " +
location.getLongitude(), illegalArgumentException);
}

// Handle case where no address was found.
if (addresses == null || addresses.size() == 0) {
if (errorMessage.isEmpty()) {
errorMessage = getString(R.string.no_address_found);
Log.e(TAG, errorMessage);
}
deliverResultToReceiver(Constants.FAILURE_RESULT, errorMessage);
} else if (!"".equals(addresses) || null != addresses || addresses.size() > 0) {
Address address = addresses.get(0);
ArrayList<String> addressFragments = new ArrayList<String>();

// Fetch the address lines using getAddressLine,
// join them, and send them to the thread.
for(int i = 0; i < address.getMaxAddressLineIndex(); i++) {
addressFragments.add(address.getAddressLine(i));
}
//Log.i(TAG, getString(R.string.no_address_found));
if (!TextUtils.isEmpty(String.valueOf(addressFragments)))
deliverResultToReceiver(Constants.SUCCESS_RESULT, TextUtils.join(System.getProperty("line.separator"), addressFragments));
}
//GetAddressString(addresses);
//return st;
}

private void deliverResultToReceiver(int resultCode, String message) {
Bundle bundle = new Bundle();
try {
if (message != null || !"".equals(message))
bundle.putString(Constants.RESULT_DATA_KEY, message);
mReceiver.send(resultCode, bundle);
} catch (NullPointerException npe) {
// TODO Auto-generated catch block
npe.printStackTrace();
}
}


Here is the logcat
