The device is an e-ink reader with a highly customized environment. It
doesn’t have the standard settings manager, nor the standard file
manager. All I can say is that:
- Emacs has the same storage permission as the other applications that
can access the storage without any problems (e.g. Termux or a
third-party file manager).
- I had to enable the permission manually, Emacs didn’t ask for it
itself (unlike e.g. the file manager does). I also tried to reboot
the device, the permission is still there but Emacs cannot access the
storage.
- When I mount the device storage on my desktop computer via USB and run
‘find -name "*emacs*"’ on it, the only thing found is the *.apk I
installed Emacs from. Again, the directories of other applications
are visible.
As no other application I use on the device (e.g. several applications I
installed from F-Droid) suffers from the storage access problems nor
requires anything unusual to access the storage, I believe it’s an Emacs
bug. Please tell me if there is anything I can do to help identifying
the cause of the problem.
