I’m a new developer working in an android app with kivy and kivymd, I can compile it without trouble, but when it comes to run it on the devices, I get python errors located in files that are created automatically when compiling with buildozer. This is the error log looking at adb logcat:

Traceback (most recent call last):

AttributeError: ‘NoneType’ object has no attribute ‘width’

My buildozer.spec requirements is the next:
requirements = python3,kivy==2.3.0,mysql-connector,pillow,requests,sdl2,kivymd==1.1.1

I’ve tried the newer versions of both kivy and kivymd as well as a few older versions, they all give me the same error. In the “material_resources.py” file, the line that displays the error is the following:

DEVICE_TYPE = “desktop”

elif Window.width >= dp(600) and Window.height >= dp(600):

The app works perfectly while on pc, but not after compiling to apk. It’s gotten to the point where I don’t know what else to do. Any help is useful, thanks in advance 🙂
