python-for-android Docker & Self-Hosted Deployment

# Dockerfile with:
#   - Android build environment
#   - python-for-android dependencies
#
# Build with:
#     docker build --tag=p4a --file Dockerfile .
#
# Run with:
#     docker run -it --rm p4a /bin/sh -c '. venv/bin/activate && p4a apk --help'
#
# Or for interactive shell:
#     docker run -it --rm p4a
#
# Note:
#     Use 'docker run' without '--rm' flag for keeping the container and use
#     'docker commit <container hash> <new image>' to extend the original image

# If platform is not specified, by default the target platform of the build request is used.
# This is not what we want, as Google doesn't provide a linux/arm64 compatible NDK.
# See: https://docs.docker.com/engine/reference/builder/#from
