# This image can be used to build an Android app using the NDK, since $ANDROID_HOME is set.
# The only "Skia-specific" thing is the depot_tools, everything else is pretty generic.
#
# The base Docker image (butomo1989/docker-android-x86-8.1:1.4-p1) has an android emulator
# that can be run by doing the following
# docker run --privileged -d --name android_em -e DEVICE="Samsung Galaxy S6" butomo1989/docker-android-x86-8.1:1.4-p1
# Then, the running container can be attached to by:
# docker exec -it android_em /bin/bash
# Of course, this Docker image can also do that, it's just a bit heavier for "emulation only"
# tasks.
