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 usabl= e 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"))<= br>

#+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?

Are there another ways to detect a xdg-compliant runtime environment a= part from these environment variables, which are also applicable to environ= ments like Termux? If so we should apply something as general as possible.<= br>
