Android Volley 库在蜂窝数据连接时出现超时错误

Question

我在我的应用程序中使用 android volley 库，当我使用 wifi 时，它可以正常工作，但蜂窝数据连接似乎有问题。在某些带有蜂窝数据的手机（LG G3 Android 6，魅族 android 5.1）中它不起作用并给出超时错误，但在（HTC 渴望 816 android 4.4，lg g3 android 5.0）中它再次工作

有什么问题？

D/ERROR: error => com.android.volley.TimeoutError

代码：

showLoadingDialog();
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                try {
                    JSONObject jobj = new JSONObject(response);
                    JSONObject jobjHRM = jobj.getJSONObject("HRM");
                    int status = jobjHRM.getInt("StatusCode");
                    if (status == 200) {
                        if (jobj.getJSONObject("Data").getBoolean("result") == true) {
                            login_info_editor.putInt("id", jobj.getJSONObject("Data").getInt("id"));
                            login_info_editor.putString("username", txtlayoutid.getEditText().getText().toString());

        }

        @Override

    AppController.getInstance().addToRequestQueue(postRequest);

尝试配置重试策略。给一个大的超时并尝试，

int socketTimeout = 30000; // 30 seconds. You can change it
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,                 
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,     
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);

postRequest.setRetryPolicy(policy);
AppController.getInstance().addToRequestQueue(postRequest);
