bug#67759: [ android ] 30.0.50; unable to access device storage

[Po Lu via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

It is hard to wrap my head around such a curt and superficial account of
different experiences, each of which might or might not be a bug.

This might seem trivial, but people have run across this pithole before:
have you erased the leading "~" character in the default file name
prompt?  If not, do so, as Android's storage directory is located at
/sdcard rather than your home folder.

But assuming that you have, you've likely omitted the trailing "/" after
the file name that informs Emacs it is a directory.  Absent this
character, file name completion will complete from / instead of /sdcard,
and your device is one of those which deny Emacs the rights to examine
/.

This isn't a bug: your device's file manager doesn't support SAF
volumes.  The Android file manager does, and even when hidden, can
generally be accessed by means of a program that launches system
activities.  A web search should answer questions in this respect.
