# Android Environment for OpenEnv
# Build with: docker build -t android-env:latest -f src/envs/android_env/server/Dockerfile .
#
# This Dockerfile creates a container with:
# - Android SDK and command-line tools
# - Android Emulator
# - android_env Python package
# - OpenEnv wrapper for android_env
#
# The container requires:
# - KVM access for hardware acceleration (Linux hosts)
# - Significant resources (4GB+ RAM, 4+ CPU cores)
#
# Environment Variables Required:
# - ANDROID_AVD_NAME: Name of the Android Virtual Device
# - ANDROID_TASK_PATH: Path to the task textproto file
#
# Example build:
#   docker build -t android-env:latest -f src/envs/android_env/server/Dockerfile .
#
# Example run:
#   docker run -p 8000:8000 \
#     -e ANDROID_AVD_NAME=Pixel_6_API_33 \
#     -e ANDROID_TASK_PATH=/workspace/tasks/my_task.textproto \
