#    -----------------------------------------------------------------------------
#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[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
' ' '
Command:
buildozer android debug run logcat

Yes we got some recent runtime fixes in “develop”

• https://github.com/kivy/python-for-android/pull/2245
• https://github.com/kivy/python-for-android/pull/2246

It might be worth giving a try @Bouchra994 change to p4a.branch = develop and do a clean buildozer android clean and a rebuild to see

[RobertFlatt]

My error about the existence of the recipe, so yes it looks like a bug. Workaround is still the same, use pure Python.
