Android Question [Solved] Android 28 and non-ssl (non-https) communication

[asales]

I use B4A 9.30 and OkHttpUtils2 in most of my apps to download images and post/get to a PHP server hosted in a non-https site.

I just change the target SDK to 28 in manifest and compile the app.
Until now all the functions thats uses internet still working.

When I need to use this lines in my apps?:

CreateResourceFromFile(Macro, Core.NetworkClearText)

android.jar / targetSdkVersion / minSdkVersion

android.jar / targetSdkVersion / minSdkVersion

I found the line above in this post, but I don't have enough information to answer my questions:
- whats is a "non-ssl (non-https) communication" in B4A?
- I use OkHttpUtils2 in most of my apps. I need to use this lines in the manifest?
Thanks in advance.

whats is a "non-ssl (non-https) communication" in B4A?

communication with a webservice over http. Not https

I need to use this lines in the manifest?

with targetsdk 28 yes if you do use http instead of https.

Scure your webservice and add a SSL Certificate. Use HTTPS and you dont need this in manifest.

Thanks.
I tested the app in a device with Android 9 and if I don't put the line, I get this error:

ResponseError. Reason: java.net.UnknownServiceException: CLEARTEXT communication to www.myserverphp.com not permitted by network security policy, Response:

So, problem solved. I need this line.
