Title: Issue with buildozer packaging on Windows 10 WSL environment
zetspiner
Hi everyone,
I'm encountering an error while trying to package my real-time face recognition model into an Android application using buildozer in a Windows Subsystem for Linux (WSL) environment on Windows 10.
I'm developing the face recognition model using Python 3.7, and I've set up a virtual environment with Kivy also based on Python 3.7.
Here's the error message I'm getting when running buildozer android debug:

--ignore-setup-py Don't run the setup.py of a project if present. This
may be required if the setup.py is not designed to
work inside p4a (e.g. by installing dependencies that
won't work or aren't desired on Android
--release Build your app as a non-debug release build. (Disables
gdb debugging among other things)

I've tried reinstalling the Android SDK and ensuring that the necessary files are present in the specified paths. However, the issue persists.
Has anyone else encountered a similar problem or have any suggestions on how to troubleshoot this? Any help would be greatly appreciated
Thanks in advance!
