Android port for GNU Emacs

[Carlos Scarinci]

I am trying out emacs-30.0.92-29 on android, alongside with termux,
following the instructions

https://sourceforge.net/projects/android-ports-for-gnu-emacs/


After a fresh installation, the addition of the lisp code in early-init.el,
and the granting of storage access, as instructed, my emacs is not able to
run any shell commands. If I open eshell, I can run termux installed
programs without a problem, but from the minibuffer or from built-in
functions, I always get

(Shell command failed with code 127 and no output)


I would like to ask if there is any other configuration required to have
access to termux installed programs (specifically texlive and tectonic)?

Thank you in advance for your help and attention. (And sorry, if this is
not the correct channel for this type of inquiry)
