Android解析JSON:http连接java.lang.IllegalArgumentException中出错

大家好，我在解析这个JSON文件时遇到问题 请帮我解决这个问题：

下面是我用来解析它的代码：

public String getJSONTextFromUrl(String url) {
        // initialize
        InputStream is = null;
        String result = "";

        // http post
        try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

        } catch (Exception e) {
            Log.e("log_tag", "Error in http connection " + e.toString());
        }

        // convert response to string
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "UTF-8"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result = URLDecoder.decode(sb.toString(), "UTF-8");
        } catch (Exception e) {
            Log.e("log_tag", "Error converting result " + e.toString());
        }

        System.out.println("JSON: = " + result);
        System.out.println("JSON SIZE: = " + result.length());

        // return result.replace(result.charAt(0), ' ');
        return result;
    }

public JSONObject getJSONFromScript(String jsonText) {

        JSONObject jObject = null;
        String result = getJSONTextFromUrl(jsonText);

        // try parse the string to a JSON object
        try {
            jObject = new JSONObject(result);
        } catch (JSONException e) {
            Log.e("log_tag", "Error parsing data " + e.toString());
            e.printStackTrace();
        }

        return jObject;

    }

这是我得到的logcat输出和错误：
