To add to what Mats already mentioned:
There are currently at least three efforts for getting better Python
support on mobiles:
- PyScript which runs Python in a browser, so you can use a web view to
host it inside an application. This does run some data science code, but
I'm not sure how far you can get with it.
- BeeWare, which aims to support multiple platforms running Python with
the same code, including mobiles.
- Kivy, which has a similar goal to BeeWare, but is more focused on
graphics heavy apps.
I don't think any of these natively integrate into an existing Java app,
though.
Work on Jython 3 is progressing very slowly. You may want to help out
here: https://github.com/jython/jython/tree/main

Thank you, Mats. I decided to contribute to wiki because I did some
research on this topic and python wiki looks the most complete one
except of this project. If community doesn't consider it as worthy to
try and avoid it too.
The best tool for my aim is chaquopy, I am exploring it passed an hour.
Sadly, creator actively juggling gradle config files, so I start
question is it worth to integrate.
Context of my task is I have a ml model on python or better to say a
python script which combines several classifiers and I want to quickly
integrate into my Android app. That's why I search today for python
integration on Android options. Android has its own ml kit and
conversion tools to tflite format, but it has its own limitations.
Thanks!

If you do add Jython, perhaps include a note about its status. This
is a
well known implementation mentioned elsewhere on the Python wiki, but
the project... how to put this politely - "isn't getting a lot of
love".
It's not "dead", that would be too harsh, releases are still being made.
Most of the Python community considers Python 2 a dead language; Jython
does not run the current Python language specification, called Python 3
(which has been out for 15 years now). There is a project in existence
to make this happen, which includes a substantial revamp of Jython, but
there's no public indication that it's making any real progress.
The current, possibly outdated, comment inthe FAQ in Jython's own wiki
(which is hosted by python.org <http://python.org>) might be
instructive:
https://wiki.python.org/jython/JythonFaq/GeneralInfo#Can_I_use_Jython_to_make_apps_for_mobile_phones.3F
<https://wiki.python.org/jython/JythonFaq/GeneralInfo#Can_I_use_Jython_to_make_apps_for_mobile_phones.3F>
The python wiki is also discouraging (remember, on wikis, somebody has
to update information, and for statements of this type, it's hard to
tell if up to date or not):
"Although Android's primary programming language is Java, there is no
known port of Jython to the platform. "
