Adding a timeStamp to the file name is only helpful if you store the PDF file in one of the Shared folders on Android 11+ and be sure that there are no conlicts with existing files created beforehand (eg with Companion).

That done it in Android API 29,30,31 for Android 28- I used File picker

29

Ok, so from which path are you picking?
So not from /Download because that wouldn't work on Android 11+.

30

Downloads --It works on Android 29+

31

It should work on all Android versions.

Thank you for your help, I really appreciate that … For now, I used 2 Extensions on my project one File Picker for Android 28-
and SAF for Android 29+ it seems that it works.

35

SAF is only needed on Android 11+ (API 30+).

36

... because AI2 decided to declare requestLegacyExternalStorage=true in the Manifest, so it continues to work on Android 10 (API 29).

:question:

No idea. This permission does not exist.

Btw, the question should be:
Why android.permission.MANAGE_EXTERNAL_FILES is declared in the Manifest with the FileTools extension?

42

No, since it doesn't exist, ignore it.
