Permission problem with TaifunFile extension

[Anke]

It's interesting how TaifunFile works perfectly right now. There's no need to edit manifest file or ask for permissions or anything. It just works. It can read and write because there's no need for permissions for ASD/shared folders.

Ok, with your test aia the text file is created / saved by the app itself and copied in the ASD. This works with Companion & APK. But if you / the user removes this file the app will no longer work (even not after uninstalling and reinstalling the app).

We should talk here about files that were created by other apps, and this will not work with the TaifunFile extension on devices with API > 28. The Storage Access Framework (SAF) must be used for this, which does not seem to be implemented in AI2 yet.
