NetworkSecurityConfig: No Network Security Config specified -- Android 7.0 error?
<p>I have some problem for android 7.0.0.</p>

<p>I use volley library for my application, and it works well except for Android 7.0</p>

<p>Here is part of my code;</p>

<pre><code>String url_goster = "http://185.126.217.71/clog.php";
RequestQueue requestQueue;

StringRequest request= new StringRequest(Request.Method.POST, url_goster, new Response.Listener&lt;String&gt;() {
    @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&lt; 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&lt;String, String&gt; getParams() throws AuthFailureError {
                Map&lt;String,String&gt; params = new HashMap&lt;String,String&gt;();
                params.put("ad",USER);
                return params;
            }
        };
        requestQueue.add(request);
    }
</code></pre>

<p>If I test my application on Android 7.0, the output of console is;</p>

<blockquote>
  <p>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.</p>
</blockquote>

<p>but this only happens Android 7.0 and application looks blank because it doesn't get a response from the internet</p>

<p>. How can i solve this problem ?</p>
