hey try to use this syntax.

@Override
protected String doInBackground(String... params) {

    String urlString = params[0];
    String userName = params[1];
    String password = params[2];
    URL url = null;
    InputStream stream = null;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL(urlString);
        urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.setRequestMethod("POST");
        urlConnection.setDoOutput(true);

        String data = URLEncoder.encode("userName", "UTF-8")
                + "=" + URLEncoder.encode(userName, "UTF-8");

        data += "&" + URLEncoder.encode("password", "UTF-8") + "="
                + URLEncoder.encode(password, "UTF-8");

        urlConnection.connect();

        OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());
        wr.write(data);
        wr.flush();

        stream = urlConnection.getInputStream();
        BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"), 8);
        String result = reader.readLine();
        return result;

    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }
    }

    try {
        Thread.sleep(2000);
    } catch (InterruptedException e) {
        e.printStackTrace();
        Log.i("Result", "SLEEP ERROR");
    }
    return null;
}

Hope this helps. :)
