I want to create a check-in macro in an android app using python

guys. I've been trying to do a task lately and it have been harder than I thought. I want to create a check-in macro in an android app using python. I have thought about three ways:

1. Simulating android in a python enviroment.
2. Use a website that runs a simulated android and use python to navigate through this site. But I have not find an answer, since those websites don't use traditional CSS components like div, but other resources.
3. Use HTTP requests (haven't worked) to simulate the use of the app.

The check-in macro would be like this:

1. Opens app.
2. Login.
3. Goes to check-in page.
4. Check-in.

Any ideas?
