java - NetworkSecurityConfig : No Network Security Config specified -- Android 7. 0 错误？

Question

我有一些关于 android 7.0.0 的问题。

我在我的应用程序中使用了 volley 库，它在 Android 7.0 之外运行良好

这是我的部分代码；

String url_goster = "http://185.126.217.71/clog.php";
RequestQueue requestQueue;

StringRequest request= new StringRequest(Request.Method.POST, url_goster, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        JSONObject veri_json;
        try {
            veri_json = new JSONObject(response);
            JSONArray serial_no = veri_json.getJSONArray("Bilgiler");

            for (int i = 0; i< serial_no.length(); i++){
                JSONObject bilgis = serial_no.getJSONObject(i);

                // JSON olarak verileri çekiyoruz
                String GELEN_SERIAL = bilgis.getString("GELEN_SERIAL");
                String TERMINAL_ADI = bilgis.getString("TERMINAL_ADI");
                String SICAKLIK_T1 = bilgis.getString("SICAKLIK_T1");
                String SICAKLIK_T2 = bilgis.getString("SICAKLIK_T2");
                String SICAKLIK_T3 = bilgis.getString("SICAKLIK_T3");
                String SON_DATA = bilgis.getString("SON_DATA");
                String NEM_H1 = bilgis.getString("NEM_H1");
                String NEM_H2 = bilgis.getString("NEM_H2");
                String NEM_H3 = bilgis.getString("NEM_H3");
                String SENSOR_1_AD = bilgis.getString("SENSOR_1_AD");
                String SENSOR_2_AD = bilgis.getString("SENSOR_2_AD");
                String SENSOR_3_AD = bilgis.getString("SENSOR_3_AD");
                int SENSOR_SAYISI = bilgis.getInt("SENSOR_SAYISI");

                kisiler.add(new Kisi(TERMINAL_ADI, SON_DATA, SENSOR_1_AD, SENSOR_2_AD, SENSOR_3_AD, SICAKLIK_T1, SICAKLIK_T2, SICAKLIK_T3, NEM_H1, NEM_H2, NEM_H3, GELEN_SERIAL, SENSOR_SAYISI));
            }
        } catch (JSONException e) {
            Log.e("JSON ALIRKEN HATA",e.getLocalizedMessage());

            Toast.makeText(getApplicationContext(), "Server'a bağlanılırken bir hata ile karşılaşıldı.", Toast.LENGTH_SHORT).show();
        }
    }
    }, new Response.ErrorListener() {
           @Override
           public void onErrorResponse(VolleyError error) {

           }
       }){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                Map<String,String> params = new HashMap<String,String>();
                params.put("ad",USER);
                return params;
            }
        };
        requestQueue.add(request);
    }

如果我在 Android 7.0 上测试我的应用程序，控制台的输出是；

D/NetworkSecurityConfig: No Network Security Config specified, using platform default I/Choreographer: Skipped 127 frames! The application may be doing too much work on its main thread.

但这只发生在 Android 7.0 上，应用程序看起来是空白的，因为它没有从互联网上得到响应

.我该如何解决这个问题？

Answer 1

这条消息没有问题:

D/NetworkSecurityConfig: No Network Security Config specified, using platform default 

D/ 表示这是一条调试消息。它表示您没有定义自己的网络安全配置，因此平台默认规则适用。这很好。

application looks empty because it does not response from the internet

据我所知，您正在解析一些 JSON，对其进行迭代，然后填充 kisiler。也许 kisiler 没有连接到您的 UI。
