    ## 6.开始编译

    编译 Android 系统镜像(Android 10 和 Android 11 ): https://zwc365.com/2020/09/13/ubuntu18-build-android10-11

    使用如下参数设定内存限制：

    ``` shell
    export _JAVA_OPTIONS="-Xmx10g"
    ```

    ## 编译尝试使用 docker 环境
    # Android 11 系统编译采坑

    ## 1.编译尝试使用 docker 环境

    ``` shell
    docker pull ubuntu:18.04
    ```

    ## 2.安装 Repo

    ``` shell
    mkdir ~/bin
    PATH=~/bin:$PATH

    curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
    chmod a+x ~/bin/repo
    ```

    如果想使用旧版 Repo 启动器, 请使用一下命令:

    ``` shell
    curl https://storage.googleapis.com/git-repo-downloads/repo-1 > ~/bin/repo
    chmod a+x ~/bin/repo
    ```

    ## 3.Ubuntu18.04 基本环境配置

    ``` shell
    apt update
    apt install python python3 curl git -y

    sudo apt-get install openjdk-8-jdk
    sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig
    ```

    ## 4.下载源码:

    将 Google 的地址 https://android.googlesource.com/kernel/manifest 替换清华的地址 https://aosp.tuna.tsinghua.edu.cn/platform/manifest 下载速度更快
    加 --depth 1 控制git深度可以极大节省硬盘空间。最终 .repo 目录 21G 左右

    ``` shell
    git config --global user.email "[email protected]"
    git config --global user.name "h1code2"

    export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'
    repo init --depth 1 -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-11.0.0_r1
    repo sync -j20
    ```

    ## 5.专有硬件库下载

    Android 11 上不加硬件库会导致刷机后无限重启，但之前 pixel 1 时没有硬件库也能启动，这里踩了一个坑。
    记得匹配好对应的 BUILD_ID 和代码, 查看 build/core/build_id.mk 文件，我的 BUILD_ID=RP1A.200720.009，pixel 3 的代号是 blueline，所以对应的下载地址是：https://developers.google.cn/android/drivers?hl=zh-cn#bluelinerp1a.200720.009, 将两个文件下载到源码根目录，然后执行，会自动生成 vendor 文件

    ``` shell
    ~/code/android11$ tar zxvf google_devices-blueline-rp1a.200720.009-6cd41940.tgz
    ~/code/android11$ tar zxvf qcom-blueline-rp1a.200720.009-f772c38c.tgz
    ~/code/android11$ ./extract-google_devices-blueline.sh
    ~/code/android11$ ./extract-qcom-blueline.sh
    ```
