#
# Reproducible reference build
#
# Usage:
#
# docker build --file build.Containerfile --output <outputdir> .
# or
# podman build --file build.Containerfile --output <outputdir> .
#
# The unsigned APKs are written to the specified output directory.
# Use `apksigner` to sign before installing via `adb install`.
# For improved reproducibility, the project directory entries can be ordered
# like this:
#
# buildah build --cap-add=sys_admin --device /dev/fuse --file build.Containerfile --output <outputdir> .
#
# In any case, the unsigned APKs are written to the specified output
# directory. Use `apksigner` to sign before installing via `adb install`.
