[tip] Export and open a PDF in Android via Termux

[Juan Manuel Macías]

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")))
