Check with this code:

public class UniversalNetworkConnection {

    public static String postJSONObject(String myurl, JSONObject parameters) {
        HttpURLConnection conn = null;
        try {
            StringBuffer response = null;
            URL url = new URL(myurl);
            conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(10000);
            conn.setConnectTimeout(15000);
            conn.setRequestProperty("Content-Type", "application/json");
            conn.setDoOutput(true);
            conn.setRequestMethod("POST");
            OutputStream out = new BufferedOutputStream(conn.getOutputStream());
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
            writer.write(parameters.toString());
            writer.close();
            out.close();
            int responseCode = conn.getResponseCode();
            System.out.println("responseCode" + responseCode);
            switch (responseCode) {
                case 200:
                    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                    String inputLine;
                    response = new StringBuffer();
                    while ((inputLine = in.readLine()) != null) {
                        response.append(inputLine);
                    }
                    in.close();
                    return response.toString();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            if (conn != null) {
                try {
                    conn.disconnect();
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }
        return null;
    }
