Hi Giller, did you test another example using these specs on Android?

[stengergilles]

Hello
Sorry for the late reply I'm on holiday.:-)
checkers.py give me the same error
example.py/example2.py/tour3d exit with no logs (last message is "Starting application main loop")

[kpiorno]

Don't worry Gilles :).I will take a look at that.

Kivy: 2.2.0.dev0
Python: 3.11.0
OS: Windows 10 Pro N, 21H2

I installed Kivy by github link, was the only option what worked on my laptop.
