Using the following code
https://gist.github.com/4072912
from kivy.uix.label import Label
from kivy.app import App
class MyApp(App):
def build(self):
#Label()
return Label(text='test')
if __name__ == '__main__':
MyApp().run()
result in a completly blank app, in my python-for-android distribution, but works fine on desktop, if i uncomment the Label() call, the app works correctly.
