我有 2 个具有相同任务的相同项目，它想使用 JsonReader 从 android 访问 Web 服务，

项目 1运行良好，一切正常，没有问题， 项目 2出现异常 ===>“com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY 但在第 1 行第 47 列是 BEGIN_OBJECT”

为了确保我什至复制并粘贴了从 proj1 到 proj2 调用 JsonReader 的类，任何人都可以帮我修复它。这是我从 Asyntasks 调用的类

public <T> T Gets(String url, List<NameValuePair> params, final Type t) {

        HttpURLConnection connection = null;// getNewHttpconnection();
        // String paramString = URLEncodedUtils.format(params, "utf-8");
        if(params != null) {
            String paramString = URLEncodedUtils.format(params, "utf-8");
            url += "?" + paramString;
        }


        try {
            URL urls = new URL(url);
            connection = (HttpURLConnection) urls.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Accept", "text/html");
            connection.setRequestProperty("Accept-Encoding", "gzip");
            connection.setReadTimeout(60000);
            connection.setConnectTimeout(60000);
            connection.connect();


            if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
                Log.e("asds", "Server returned HTTP " + connection.getResponseCode()
                        + " " + connection.getResponseMessage());
                return null;
            }
            else
            {
                int fileLength = connection.getContentLength();
                InputStream inputStream = connection.getInputStream();
                String contentEncoding = connection.getContentEncoding();
                if (contentEncoding != null && contentEncoding.equalsIgnoreCase("gzip")) {
                    inputStream = new GZIPInputStream(inputStream);
                }
                JsonReader reader = new JsonReader(new InputStreamReader(inputStream, "UTF-8"));
                 reader.setLenient(true);
                System.out.print(reader);
                Gson gson = new GsonBuilder().create();
                T temp =  gson.fromJson(reader, t);
                //     tem = temp;
                inputStream.available();
                inputStream.close();
                return  temp;
            }
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        } catch (ClientProtocolException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        } catch (IOException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
        return null;
    }`
