嗨，我正在使用 volley 库重建 API 调用

这是我发送 XML 数据和接收 xml 响应的测试代码（我只需要成功接收字符串格式的响应）

String url ="https://prdesb1.singpost.com/ma/FilterOverseasPostalInfo";
        final String payload = "<OverseasPostalInfoDetailsRequest xmlns=\"http://singpost.com/paw/ns\"><Country>AFAFG</Country><Weight>100</Weight><DeliveryServiceName></DeliveryServiceName><ItemType></ItemType><PriceRange>999</PriceRange><DeliveryTimeRange>999</DeliveryTimeRange></OverseasPostalInfoDetailsRequest>\n";

        RequestQueue mRequestQueue;

// Instantiate the cache
        Cache cache = new DiskBasedCache(getCacheDir(), 1024 * 1024); // 1MB cap

// Set up the network to use HttpURLConnection as the HTTP client.
        Network network = new BasicNetwork(new HurlStack());

// Instantiate the RequestQueue with the cache and network.
        mRequestQueue = new RequestQueue(cache, network);

// Start the queue
        mRequestQueue.start();

// Formulate the request and handle the response.
        StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        // Do something with the response
                        Log.v("tesResponse","testResponseS");
                        Log.v("response",response);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        // Handle error
                        Log.v("tesResponse","testResponseF");
                        Log.v("error",error.toString());
                    }
                }
        ){
            @Override
            public String getBodyContentType() {
                return "application/xml; charset=" +
                        getParamsEncoding();
            }

            @Override
            public byte[] getBody() throws AuthFailureError {

                String postData = payload;
                try {
                    return postData == null ? null :
                            postData.getBytes(getParamsEncoding());
                } catch (UnsupportedEncodingException uee) {
                    // TODO consider if some other action should be taken
                    return null;
                }
            }
        };
//        stringRequest.setRetryPolicy(new DefaultRetryPolicy(5*DefaultRetryPolicy.DEFAULT_TIMEOUT_MS, 0, 0));
        stringRequest.setRetryPolicy(new DefaultRetryPolicy(0, 0, 0));

// Add the request to the RequestQueue.
        mRequestQueue.add(stringRequest);

我已经测试了字符串url和payloadPOSTMAN 并给出了成功的结果。但不知道为什么我的 android 应用程序会出现此错误

请注意仅 API 23+（android 6.0 及更高版本）API 22 工作正常的问题！

我尝试设置重试策略但不起作用。任何人都知道代码有什么问题。提前致谢
