NetworkSecurityConfig: No Network Security Config specified — Android 7.0 error?

Question

I have some problem for android 7.0.0.

I use volley library for my application, and it works well except for Android 7.0

Here is part of my code;

<         


        

Answer 1

try adding this to the manifest.xml

<uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

and change the android emulator to pixel 2 API 28 from the AVD manager it worked for me in both windows and mac

Answer 2

So, I don't think the previous answer was clear enough. (I spent a couple of hours trying to "debug" this)

If you're seeing this prompt, the fact that it says

D/ blablabla

means that this is a Debug, and not an error. It's more like a notification to let you know that you didn't specify the NetworkSecurityConfig, and that it decided by itself to set it to default. Nothing wrong.

Your error, however, will show itself as:

E/ blebleble

TL;DR You might be looking at the wrong place if you're trying to debug an error.

Answer 3

There is no problem with this message:

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

The D/ indicates that this is a debugging message. It indicates that you do not have your own network security configuration defined, and so platform-default rules apply. This is perfectly fine.

application looks empty because it does not response from the internet

Near as I can tell, you are parsing some JSON, iterating over it, and populating kisiler. Perhaps kisiler is not connected to your UI.
