Nice. Here is a slightly different approach.
- Rather than using new set of API, pythonista API is used as standard. For example, "example1.py" (modified example of yours) runs directly in pythonista (currently it requires one line change from kivy code)
- In Kivy, you need an extra file "ui.py". All the code is in this file. It is just a wrapper on kivy objects.
- This code is not complete and a lot needs to be done.
