Android Question External directory (Android11) and Permission Denied

[jnbarban]

Hello,
I am trying to access a file from another application in the External folder and I am facing an EACCES (Permission denied) error.

I started from the example project provided by the post:

Manage External Storage - access internal external storage >= SDK 30

Google seems intent on dumbing down Android to the point of uselessnes to me. I think of my devices as little computers and I want a proper file system on them, not the limited tortuous things that Google offers and that I don't understand, ContentChooser, FileProvider, ... o_O I'm getting old...

in which I modified only the contents of Button1_Click.

I am joining you.
If you want to test it, you must modify the text "AnOtherApp" by the name of an existing package.

OK,
so how are we supposed to share a file with another application?
The 2 applications are ours and we can make the necessary modifications.
