AOSP基础（TODO）

1 搭建环境

Ubuntu22，基于WLS2

sudo apt update && sudo apt upgrade -y sudo apt install -y git curl python3 build-essential libssl-dev libffi-dev libpython3-dev \ openjdk-17-jdk zip unzip bison flex m4 libncurses5-dev x11proto-core-dev libx11-dev \ lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc ccache # 配置git基础信息（必须，否则repo会报错） git config --global user.name "aosp-dev" git config --global user.email "aosp@example.com"

拉代码

cd ~/aosp rm -rf .repo

使用清华的镜像。同时repo init 追加 --repo-url 参数 ，绕过默认谷歌地址。

repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest \ -b android-14.0.0_r40 \ --repo-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo \ --no-repo-verify

repo sync -j4 -c --no-tags

jc@LAPTOP-E7FQL6BT:~/qssitest$ repo init --depth=1 --current-branch -u https://git.codelinaro.org/clo/la/la/system/manifest.git -b release -m AU_LINUX_ANDROID_LA.QSSI.14.0.R1.14.00.00.1001.246.00.xml --repo-url=https://git.codelinaro.org/clo/tools/repo.git --repo-branch=qc-stable Get https://git.codelinaro.org/clo/la/la/system/manifest.git remote: Enumerating objects: 1461, done. remote: Counting objects: 100% (1461/1461), done. remote: Compressing objects: 100% (100/100), done. remote: Total 1461 (delta 1453), reused 1364 (delta 1361), pack-reused 0 (from 0) Receiving objects: 100% (1461/1461), 38.08 MiB | 37.00 KiB/s, done.

Your identity is: jc <chenjiang-c@awear.ai> If you want to change this, please re-run 'repo init' with --config-name repo has been initialized in /home/jc/qssitest

一共的空间占用大概是168G。

jc@LAPTOP-E7FQL6BT:~/aosp$ du -sh . 168G .

文件大概如下：

jc@LAPTOP-E7FQL6BT:~/aosp$ ls Android.bp WORKSPACE bionic bootstrap.bash cts developers device frameworks kernel libnativehelper pdk prebuilts system toolchain BUILD art bootable build dalvik development external hardware libcore packages platform_testing sdk test tools
