# vim: ft=dockerfile:
# Dockerfile to build aria2 android binary
#
# $ sudo docker build -t aria2-android - < Dockerfile.android
#
# After successful build, android binary is located under
# /root/build/aria2.  You can copy the binary using docker cp.  For
# example, to copy aria2c binary to host file system location
# /path/to/dest, do this:
#
# $ sudo docker run --rm -it -v /path/to/dest:/out aria2-android cp /root/build/aria2/src/aria2c /out
