Hi all, I have recently installed TeX live on Android inside Termux:
$ pkg install texlive-installer (https://wiki.termux.com/wiki/TeX_Live) And I've managed to open a PDF exported from Org using an external android viewer (mupdf, downloaded from f-droid). The Termux command is termux-open. You need to add: (setq org-file-apps '((auto-mode . emacs) (directory . emacs) ("\\.mm\\'" . default) ("\\.x?html?\\'" . default) ("\\.pdf\\'" . "termux-open %s"))) It is necessary also to uncomment the line 'allow-external-apps = true' in '~/.termux/termux.properties'. And to open the PDF from AUCTeX: (setq TeX-view-program-list '(("termux" "termux-open %o"))) (setq TeX-view-program-selection '(((output-dvi has-no-display-manager) "dvi2tty") ((output-dvi style-pstricks) "dvips and gv") (output-dvi "xdvi") (output-pdf "termux") (output-html "xdg-open"))) A screencast: https://imgur.com/a/iBvwDTo Best regards, Juan Manuel
