# atome for Android, cross-built with the NDK. Built and run by docker/run.sh.
#
# Build only: running the tests needs an emulator or a device, which is past
# what a container does well. What this proves is that the default toolkit, the
# decoders, and the FLAC writer compile and link for aarch64-linux-android —
# which nothing else here would notice breaking, since cpal's Android path is
# `cfg`-split.
# The NDK ships x86-64 Linux binaries only, so this is an amd64 container even
# on an arm64 host.
