Handler{40664220} sending message to a Handler on a dead thread

Question

I am getting this error my code is, can anyone help please

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
        new FetchAddressTask().executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, Constants.USER_CURRENT_LOCATION);
    else
        new FetchAddressTask().execute(Constants.USER_CURRENT_LOCATION);


    class FetchAddressTask extends AsyncTask<LatLng, String, String> {
    @Override
    protected void onPreExecute() {
        // showDialog();
        // showMyDialog();
        DialogHelper.showTrasparentDialog(EnterBikeInfoActivity.this);
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(LatLng... latLngs) {

        String result = getCurrentLocationViaJSON(latLngs[0].latitude, latLngs[0].longitude);
        if (result == null)
            result = "";
        return result;
    }

    @Override
    protected void onPostExecute(String result) {
        if (result == null || result.length() == 0) {
            DialogHelper.showDialogMessage(BikeApp.getInstance(), "Unable to retrieve the address.");
        } else {
            addressEditText.setText(result);
        }

        DialogHelper.dismissTransparentDialog();
        super.onPostExecute(result);
    }
}


 public String getCurrentLocationViaJSON(double lat, double lng) {
    JSONObject jsonObj = getLocationInfo(lat, lng);
    Log.i("JSON string =>", jsonObj.toString());
    String currentLocation = "testing";
    // String street_address = null;
    // String postal_code = null;
    try {
        String status = jsonObj.getString("status").toString();
        Log.i("status", status);
        if (status.equalsIgnoreCase("OK")) {
            JSONArray results = jsonObj.getJSONArray("results");
            int i = 0;
            Log.i("i", i + "," + results.length()); // TODO delete this
            JSONObject r0 = results.getJSONObject(i);
            String v = r0.getString("formatted_address");
            currentLocation = v;
            Log.i("JSON Geo Locatoin =>", currentLocation);
            return currentLocation;
        }
    } catch (JSONException e) {
        Log.e("testing", "Failed to load JSON");
        e.printStackTrace();
    }
    return "";
}

getLocationInfo(lat, lng); funtion fetches address info from an http request, my flow is coming into FetchAddressTask doInBackground with correct address but when it return the address it give me this error message.
