مشکل در اتصال به url در پروژه Note

کد وب سرویس :

 public class webservice {

    public static String readUrl(String url) {
        try {
            HttpClient client = new DefaultHttpClient();
            HttpPost method = new HttpPost(url);
            HttpResponse response = client.execute(method);
            InputStream inputstream = response.getEntity().getContent();
            String result = convertInputStreamtoString(inputstream);
            return result;
        }
        catch (ClientProtocolException e) {
            e.printStackTrace();
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }


    private static String convertInputStreamtoString(InputStream inputstream) {

        BufferedReader reader = new BufferedReader(new InputStreamReader(inputstream));
        StringBuilder builder = new StringBuilder();
        String line = "";
        try {
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }
            return builder.toString();
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}
