App exists immediately when importing kivy.core.window.Window

[snuq]

Versions

• Python: 3.8.1
• OS: Build: Xubuntu 18.04, Run: Android 6.0.1
• Kivy: master branch
• p4a: develop branch

Description

Might be related to: kivy/kivy#6400
App builds fine, no unexpected errors.

On android when running my kivy app, i get the notification in my log:
[INFO ] [WindowSDL ] No running App found, exit.
No errors or traceback happens.

this seems to happen as soon as i run:
from kivy.core.window import Window

If that line is removed, the app will not crash.

Same for me but with kivy 1.11.1.
This broke with #2113
Works fine on 66f6a34

edit: oops, mentioned incorrect PR at first
