[Python] How I can use iop-pyhton package on android?

I am using a packge name "iop-python" for my kivy app. It is not present inside the pythonforandroid for compilation so i code a recipe for it. But I am having issue in writing the recipe.

iop-python package git repo link:

https://github.com/BukiOffor/hydra-python-api/tree/main

I am having to compile this package using pythonforandroid

I am having to compile this iop-python using pythonforandroid so it will run on android

Recipe code
