Requisição Https

Mobile Android
#1

Galera,

O Web Service que vou consumir utiliza Https, sendo assim o que devo alterar no meu código abaixo pra funcionar a requisição?

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

        try {
            Gson gson = new Gson();
            String urlCnx = urlWs+"athusr?CUSUARIO="+login+"&CSENHA="+senha;
            StringBuilder execucao = new StringBuilder();
            HttpURLConnection urlConnection = null;
            BufferedReader reader = null;

            try {
                URL url = new URL("https://webserviceteste/get/teste");
                urlConnection = (HttpURLConnection) url.openConnection();
                urlConnection.setRequestMethod("GET");
                urlConnection.setRequestProperty("Content-type", "application/json");
                urlConnection.setRequestProperty("Accept", "application/json");
                urlConnection.setDoOutput(true);
                urlConnection.setConnectTimeout(Integer.valueOf(timeOut));
                urlConnection.connect();
                Scanner scanner = new Scanner(url.openStream());
                while (scanner.hasNext()) {
                    execucao.append(scanner.next());
                }
                conexaows = gson.fromJson(execucao.toString(), Login.class);
                urlConnection.disconnect();

            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            System.out.println(conexaows.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

Alguma sugestão?

Obrigado
