Hi all

With Emacs in Termux M-: (browse-url-xdg-open "http://gnu.org") opens

the URL in an Android browser. But M-: (browse-url-default-browser

"http://gnu.org") errors with "No usable browser found". This is

because even the most recent browse-url-can-use-xdg-open

#+begin_src emacs-lisp :eval no

  (defun browse-url-can-use-xdg-open ()

    "[...]"

    (and (or (getenv "DISPLAY") (getenv "WAYLAND_DISPLAY"))

        (executable-find "xdg-open")))

#+end_src

returns nil because none of the environment variables is set.

Should browse-url-can-use-xdg-open be changed to detect the situation of Termux?
