Description

Including scipy yields an error when loading the module. Different errors for 32 bit and 64 bit pacakges.

Error for 32 bit packages:

dlopen failed: "/data/data/com.autosportlabs.podium/files/app/_python_bundle/site-packages/scipy/_lib/_ccallback_c.so" is 64-bit instead of 32-bit

Error for 64 bit pacakges:

dlopen failed: "/data/data/com.autosportlabs.podium/files/app/_python_bundle/site-packages/scipy/_lib/_ccallback_c.so" has unexpected e_machine: 62

# 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:

32 bit builds:

export APP_ANDROID_ARCH=armeabi-v7a
buildozer android debug

64 bit builds:

export APP_ANDROID_ARCH=arm64-v8a
buildozer android debug

scipy is not pure Python and does not have a recipe - this is not going to work.

The messages are due to pip downloading the binaries for some other architecture, probably because the wheel is named without considering Android.
