1. 下载ubuntu desk lts（桌面稳定）版本
点击如下链接路径，下载
下载Ubuntu桌面系统 | Ubuntu
ubuntu版本有 desk server iot 云等根据业务不同的各种版本。
建议使用desk 04（ubuntu 1年release 2次 4月份的是04 10月份的是10）的 lts（long term support 长期支持，可获得不断更新的应用。）的版本，我用了desk版本的18.04 lts。（最新的是22.04，也可以试试）

3.虚拟机下安装ubuntu
3.1 新建：（文件夹路径不要用默认的c盘，选择大一点空间的盘符）

4. 下载源码前的配置
4.1 更新安装源
sudo cp /etc/apt/source.list /etc/apt/source.list.bk
sudo chmod 777 /etc/apt/source.list
sudo gedit /etc/apt/sources.list
加入如下源

4.2 安装jdk-11
sudo apt-get update
sudo apt-get install openjdk-11-jdk
5. 源码下载
源码国内不能直接下载，参看：清华和中国科技大的下载方式
- 清华大学 AOSP 镜像: https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/.
- 中国科技大学 AOSP 镜像: https://mirrors.ustc.edu.cn/help/aosp.html.
5.1 repo 配置
sudo apt install curl
sudo apt-get install git
mkdir ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
5.2 下载方式1
- 下载aosp-latest.tar https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar
- 解压aosp-latest.tar
- repo sync 同步
5.3 下载方式2(也是传统下载方式，google的官方下载方式)
- 创建文件夹 mkdir aosp-13
- cd aosp-13
- 初始化（默认服务器release的最新版本 ）
repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest
- 同步下载代码
repo sync
-
等等等代码下载完,就看到全部文件夹了
