I can't send you the whole Android file. I can send you the parts of interest ...

Obviously, anything could be in the org babel script, because it either runs or it doesn't. So, there isn't a lot of value in what I have sent here.
The critical issue is that Termux does not allow write access to /tmp on the android device. So, you have to use some other path for that. I use the "home" directory in Termux via:
> set-variable org-babel-remote-temporary-directory
> "/data/data/com.termux/files/home/"
Thanks!
