android volley库在蜂窝数据连接中给出超时错误

即时通讯使用Android排球库为我的应用程序和当我使用wifi工作但它似乎有蜂窝数据连接的问题。 在一些手机（LG G3 Android 6，魅族Android 5.1）与蜂窝数据它不工作，并给出超时错误但在（HTC欲望816 android 4.4，LG g3 android 5.0）再次其工作

问题是什么？

logcat的：

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

码：

 showLoadingDialog(); StringRequest postRequest = new StringRequest(Request.Method.POST, url, new Response.Listener() { @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()); login_info_editor.putString("password", txtlayoutpass.getEditText().getText().toString()); login_info_editor.putBoolean("loged", true); login_info_editor.commit(); checkversion(); } else { login_info_editor.clear(); login_info_editor.commit(); txtlayoutid.requestFocus(); Toast.makeText(getApplicationContext(), "نام کاربری یا کلمه ی عبور اشتباه است", Toast.LENGTH_LONG).show(); txtlayoutid.startAnimation(shake); txtlayoutpass.startAnimation(shake); hideLoadingDialog(); } } else { Toast.makeText(getApplicationContext(), "ارور " + status, Toast.LENGTH_LONG).show(); } } catch (JSONException e) { } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { hideLoadingDialog(); Log.d("ERROR", "error => " + error.toString()); } } ) { @Override protected Map getParams() throws AuthFailureError { Map params = new HashMap(); params.put(xxxxxx); params.put(xxxxxx); params.put(xxxxxx); return params; } @Override public String getBodyContentType() { return "application/x-www-form-urlencoded; charset=UTF-8"; } }; AppController.getInstance().addToRequestQueue(postRequest);

尝试配置重试策略。 给出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);
