构建Android编译环境(CentOS 8)

备注

我最初想通过CentOS 8来作为构建Android开发编译环境，不过参考LineageOS的官方文档，社区主要采用Ubuntu，所以我近期实践采用 构建Android编译环境(Ubuntu)

准备工作

我采用Android的编译环境是在 Docker Atlas 部署，通过 从Dockerfile构建Docker镜像 创建一个CentOS 8纯净环境，然后从初始环境安装必要的编译工具链来构建Android编译环境。

  • 在本地创建一个 studio 目录，进入这个目录，然后 - 如果你只是编译android系统，则存放以下名为 android-build 的Dockerfile - 如果你想开发android系统，则存放以下名为 android-studio 的Dockerfile

android-build
# Build Android Studio image with ssh:
# ------------------------------------
# docker build - < android-studio

# create container:
# -----------------
# docker run -itd --hostname android-studio --name android-studio local:android-studio

# create container with volume:
# -----------------------------
# docker volume create data
# docker run -itd --hostname android-studio --name android-studio -v data:/data local:android-studio

# create container with volume and static ip:
# -------------------------------------------
# docker volume create data
# docker network create --subnet=172.18.0.0/16 data-net
# docker run -itd --hostname android-studio --name android-studio -v data:/data \
#   --net data-net --ip 172.18.0.252 local:android-studio

# create container with volume and static ip, then limit resource and map port:
# -----------------------------------------------------------------------------
# docker volume create data
# docker network create --subnet=172.18.0.0/16 data-net
# docker run -itd --hostname android-studio --name android-studio -v data:/data \
#   --net data-net --ip 172.18.0.252 --memory=2048M --cpus="1.5" \
#   -p 2222:22 -p 8080:80 local:android-studio
