#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

I'm not sure what's wrong here, I haven't encountered this error. However, there are a few hacky bits of the python3 build that I hope to fix soon and could affect this, so hopefully one of them will deal with it.
