Issue with kivy==master
This example crashes on Android load at main.py line 16
Log shows Window as NoneType object.
from kivy.app import App
from kivy.uix.label import Label

from kivy.core.window import Window
class Demo(App):
def set_background_color(self):
with self.label.canvas.before:
Color(0.5, 0.0, 0.5)
Rectangle(size=Window.size)
def _resize_handler(self,obj,size):
self.set_background_color()

Window.bind(size=self._resize_handler)
self.label = Label(text = 'Greetings Earthlings')

Command:
1) Kivy==master produces crash:
p4a clean_all
p4a apk --requirements=python3,kivy==master
2) Kivy default produces no crash
p4a clean_all
p4a apk --requirements=python3,kivy
3) Kivy==master as a change to default (so no clean_all before) produces no crash
p4a apk --requirements=python3,kivy==master.p4a file:
