[asales]

This library CustomRSSView works fine in Android 4.2 and 4.4:
https://www.b4x.com/android/forum/threads/customrssview.42297/

But in Android 6.0 and 7.0, I get this error below, when I try to parser the online xml.

How I can fix it?

Thanks in advance for any tip.

The problem is in the example program. It sets the targetSdkVersion to 24 (manifest editor) and it doesn't manage runtime permissions. The simplest solution is to change it to 19. You will need to first uninstall the app from the device.

yes it works like that
but now we have to have targetSdkVersion to 28 and up , how we make it work?

Just use the necessary RuntimePermissions...

Dim rp as RuntimePermissions
rp.CheckAndRequest(.......)

Seeing the error probably you will need:

rp.GetSafeDirDefaultExternal("")

Of course you will need to add the RuntimePermissions library.
