what must I add to fix this ?

Start with using the forumsearch before asking
err_cleartext_not_permitted

One of the threads found is android.jar / targetSdkVersion / minSdkVersion which must have a reason. As this thread is a really important one regarding changes in the Android SDK you should revisit the thread.

- 28 - Foreground services require a new non-dangerous permission. It is added automatically if using B4A v9+.
- 28 - The old http SDK is not available by default. This will cause problems with native libraries such as Google Maps who rely on the old SDK. To enable it: https://www.b4x.com/android/forum/t...ar-error-in-android-9-pie.103247/#post-649875
- 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:
Code:
CreateResourceFromFile(Macro, Core.NetworkClearText)

this search result doesnt give any result except my own message: err_cleartext_not_permitted

After adding the required text to manifest , the app directly crashes on android 8 devices. I will debug and post what causes the crash. I have changed the target apk to 26 again temporarily.

i have the same issue and found this thread:

https://stackoverflow.com/questions/45940861/android-8-cleartext-http-traffic-not-permitted

what do we need to do on our b4a apps?

Add this to project manifest,

SetApplicationAttribute(android:usesCleartextTraffic, "true")

I have tested it in Android 8 and 9.
