# Android emulator runner — slim on purpose: the SDK proper (platform-tools,
# emulator, system image, AVD) lives on the stack's PVC and is installed by
# entrypoint.sh on first boot, so this image carries only the JDK,
# cmdline-tools and the native libraries the emulator needs at runtime.
#
# Rebuild + push (rare — only when tool/library versions bump):
#   docker build -t forgejo.viktorbarzin.me/viktor/android-emulator:api36-v1 .
#   docker push forgejo.viktorbarzin.me/viktor/android-emulator:api36-v1
