1.安装必需的软件包 AOSP 9.0 或更高版本
sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev libc6-dev-i386 x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig2.安装必需的软件 清华大学开源软件镜像站
sudo apt-get update# 安装 repo 工具
mkdir ~/bin
curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo
chmod a+x ~/bin/repo
# 配置环境变量
vim ~/.bashrc
# 添加一下内容
PATH=$PATH:~/bin
export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
# 保存退出执行以下命令
source ~/.bashrc3.初始化并且同步代码 AOSP 开始开发
cd ~
mkdir aosp
cd ~/aosp
# 初始化repo，指定源码分支为 `android-10.0.0_r41`
repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-10.0.0_r41
# 配置git名称和邮箱
git config --global user.name xx
git config --global user.email xx@xx.xx
# 同步源代码,耗时较久
repo sync -j44.构建代码
# 查看处理器架构,我这边是x86_64
xm@ubuntu:~$ arch
x86_64
cd ~/aosp
source build/envsetup.sh
# 输入lunch aosp_x86_64-eng(aosp_$arch-eng) 或直接输入lunch 键入数字选择，如下输入26
xm@ubuntu:~/aosp$ lunch
You're building on Linux

#使用make -j<number> 命令进行指定线程数编译，也可以使用 m 命令自动选择最大线程数，我这个虚拟机分配了4处理器4核心
make -j125.虚拟机运行系统（需要开启硬件加速）
打开虚拟机中的硬件加速功能 虚拟机->设置->处理器->虚拟化引擎->虚拟化Intel VT-X/EPT或AMD-V/RVI (需要关机后设置)
# 编译完成后通过emulator在模拟器中启动
cd ~/aosp
emulator
# 找不到emulator命令再重复执行以下命令后执行 1. sourch build/envsetup.sh 2. lunch编译遇到的问题
1.编译使用了m 命令自动选择最大线程数
xm@ubuntu:~/aosp$ m

Error: exited with code: 1
******************************
You have tried to change the API from what has been previously approved.
To make these errors go away, you have two choices:
1. You can add '@hide' javadoc comments to the methods, etc. listed in the
errors above.
2. You can update current.txt by executing the following command:
make test-api-stubs-docs-update-current-api
To submit the revised current.txt to the main Android repository,
you will need approval.
******************************1.处理方式：降低编译线程，调整交换分区，参考Android10.0编译 make api-stubs-docs-update-current-api问题
