Android distribution

[theCapypara]

As mentioned in the PyOxidizer issue (indygreg/PyOxidizer#705) a distribution for Android would be great and I'll try and see if I can get something basic to work.

How about trying termux?

[cognifloyd]

I would like to use pantsbuild/pants in termux, but pants uses PBS, so I need a PBS build for termux.

What would that take?

[cognifloyd]

For pants, I need python 3.9. eventually that will get bumped to 3.11.

Here are the patches termux applies to python when building it:
https://github.com/termux/termux-packages/tree/master/packages/python

Several of the patches seem to deal with musl.
edit: the patches copy some functions from musl where bionic, the android libc, doesn't support what's needed. So, musl is a red Herring here.

Here is my uname -a:

Linux localhost 4.19.278-g7b0944645172-ab10812814 #1 SMP PREEMPT Thu Sep 7 05:43:03 UTC 2023 aarch64 Android

So, I guess i would need this triple:
aarch64-unknown-linux-musl

Or maybe
aarch64-unknown-linux-android28

Possibly with some other patches to use the TERMUX_PREFIX which on my device is: /data/data/com.termux/files/usr

more details:

~ $ echo $HOME
/data/data/com.termux/files/home
~ $ echo $PREFIX
/data/data/com.termux/files/usr
~ $ ls /data/data/com.termux/files
home  usr
~ $ ls /data/data/com.termux/files/usr
bin  etc  include  lib  libexec  share  tmp  var

The link I posted before was to the primary termux build of python, which right now is 3.11.
There are community builds of Python 3.7-3.10, I've included links to the built termux deb files for 3.9 for comparison.

• 3.7 build recipe and patches
• 3.8 build recipe and patches
• 3.9 build recipe and patches
  • python3.9_3.9.18_aarch64.deb
  • python3.9_3.9.18_arm.deb
  • python3.9_3.9.18_i686.deb
  • python3.9_3.9.18_x86_64.deb
• 3.10 build recipe and patches

It would be very meaningful to provide android support.

• Krita support android app but currently lack of plugin support due to difficulty in packaging python as they mentioned in their forum. Having python on android could potentially make krita-ai-diffusion plugin available.
• I am also personally trying to build tensorflow on Termux which bazel rules_python will download a glibc python and hinder the build process. Having Android support would be very meaningful.
