Android Question problem http on android 9

Try to implement what is mentioned in this post:
https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/

- 28 - Non-ssl (non-https) communication is not permitted by default. It can be enabled in B4A v9+ by adding this line to the manifest editor:
Click to expand...
Code: Copy 
CreateResourceFromFile(Macro, Core.NetworkClearText)

Edit: I noted that you are using B4A v.8.5. Try to add this to the manifest:
Code: Copy 
SetApplicationAttribute(android:usesCleartextTraffic, "true")

Thanks for your message.

Add this to the manifest and it does NOT work.

Thanks Erel! I will buy version 9.01 of B4A and see if the error continues and will notify you.

You did not get the point. Http is insecure, Https is secure (encrypted). Android 9 does not allow insecure connections unless you change the setting. It's not an error.

Can you post the unfiltered logs? (Just uncheck the box next to the logs). There must be a message as Erel mentioned.

Set targetSDK to <25 (if you don't want to publish your app to google play) and try again.

Yes... but... It's VERY important to use RSA/AES (= https) so that the connection is ecrypted. OKHttpUtils does this automatically for you. Otherwise all of the traffic can be hacked/read easily. Take care of it when you publish such an app. Customers will NOT like it and you WILL get into problems.

Another one: I can access your system via my browser just by typing the IP address from your post :D XAMPP ist good for test environments but it's not for production systems.

Note: Of course I will not do anything (but I could).
