Hello, my name is Nelson and I can help you with this project. It is not possible to run a python-written program on android natively, since the only programming language supported for native apps development is currently java.
That being said this is probably not what you want anyways. I would say the right way to go here is to make your python code be a server side service, and provide a means for the android app to communicate with it.
Anyways, I need more details in order to get a proper time estimation. Let's discuss it via chat.
Best regards
