一、 前言
最近准备更新专栏文章,AOSP源码自然也需要进行更新了,但这次不是为最新的android 13, 而是取android 12的最新tag version: android-12.1.0_r27,这应该是市面上的主流版本。
- 每次更新,自然也会遇到问题,所以就记录一下
- 另外,这次我们将直接配置本地服务器,而不是通过docker,让每次执行更简单,o(@)o
二、系列文章
第1篇:Repo下载AOSP源码:基于ubuntu22.04 环境配置
第2篇:Repo下载、编译AOSP源码:基于Ubuntu 21.04,android-12.1.0_r27
三、 服务器配置
3.1 Repo 工具配置
请参考第1篇文章的第2节和第3节,完成repo、 python3.9的配置
3.2 AOSP 依赖配置
谷歌官方依赖
sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 libncurses5-dev lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig
补充依赖
sudo apt install libncurses5
四、 下载源码
4.1 下载 aosp tar ball
- 直接下载tar包速度更快,所以直接列出此方法
wget -c https://mirrors.tuna.tsinghua.edu.cn/aosp-monthly/aosp-latest.tar # 下载初始化包
tar xf aosp-latest.tar
4.2 同步代码
- 联网同步经常会失败,失败后再次repo sync直到提示完全成功
- 对于遇到的错误,请参考楼下的错误处理方法
- 示例
```bash
szhou@bc04:~/aosp/aosp$ repo sync -j4
4.3 切分支
4.3.1 查看可用分支
- 使用 git branch -a 可查看所有可用分支
szhou@bc03:~/works/aosp/aosp$cd .repo/manifests
szhou@bc03:~/works/aosp/aosp/.repo/manifests$ git branch -a
- 使用 git branch -a | grep “android-12.1” 只看S版本的最新分支情况
szhou@bc04:~/aosp/aosp/.repo/manifests.git$ git branch -a | grep "android-12.1"
remotes/m/android-12.1.0_r27 -> origin/android-12.1.0_r27
remotes/origin/android-12.1.0_r1
remotes/origin/android-12.1.0_r10
remotes/origin/android-12.1.0_r11
remotes/origin/android-12.1.0_r12
remotes/origin/android-12.1.0_r13
remotes/origin/android-12.1.0_r14
remotes/origin/android-12.1.0_r15
remotes/origin/android-12.1.0_r16
remotes/origin/android-12.1.0_r17
remotes/origin/android-12.1.0_r18
remotes/origin/android-12.1.0_r19
remotes/origin/android-12.1.0_r2
remotes/origin/android-12.1.0_r20
remotes/origin/android-12.1.0_r21
remotes/origin/android-12.1.0_r22
remotes/origin/android-12.1.0_r23
remotes/origin/android-12.1.0_r24
remotes/origin/android-12.1.0_r25
remotes/origin/android-12.1.0_r26
remotes/origin/android-12.1.0_r27
remotes/origin/android-12.1.0_r3
remotes/origin/android-12.1.0_r4
remotes/origin/android-12.1.0_r5
remotes/origin/android-12.1.0_r6
remotes/origin/android-12.1.0_r7
remotes/origin/android-12.1.0_r8
remotes/origin/android-12.1.0_r9
szhou@bc04:~/aosp/aosp/.repo/manifests.git$
可见 android-12.1.0_r27 为最新版本,我们就下载这一个版本
4.3.2 切换分支
- 如下在 -b 后面追加分支名称,执行 repo init命令
- repo sync 同步分支代码
szhou@bc04:~/aosp/aosp$ repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-12.1.0_r27
.repo/manifests/: discarding 491 commits
Your identity is: szhou<66176468@qq.com>
If you want to change this, please re-run 'repo init' with --config-name
repo has been initialized in /home/szhou/aosp/aosp
szhou@bc04:~/aosp/aosp$ repo sync -j4
4.4 处理Repo错误
目前遇到的repo同步错误,通过删除错误的project子目录之后,基本都可以完成同步,尚未遇到过异常。也可详细参考第1篇文章的介绍
- fatal: 包有 36684 个未解决的 delta
- fatal: fetch-pack: invalid index-pack output
- error: Cannot fetch platform/packages/apps/Settings from
处理 delta 中: 87% (249971/286655), 完成 1 个本地对象.

Try re-running with "-j1 --fail-fast" to exit at the first error.
解决办法如下所示, 将失败的子项目,做 rm -rf 处理,记得同一个错误,要删除2个部分
szhou@bc04:~/aosp/aosp$ rm -rf packages/apps/Settings
szhou@bc04:~/aosp/aosp$ rm -rf .repo/projects/packages/apps/Settings.git/
szhou@bc04:~/aosp/aosp$ repo sync

五、编译测试
5.1 编译 aosp_x86_64-eng
- 为了跑模拟器,选择使用aosp_x86_64-eng项目进行编译测试
szhou@bc04:~/aosp/aosp$ source build/envsetup.sh
szhou@bc04:~/aosp/aosp$ lunch aosp_x86_64-eng

5.3 编译错误处理
对于AOSP的官方源码的编译,出现错误大致有3种情况:
- 代码未同步成功
- 代码同步成功,但经过一系列git操作,导致分支信息错乱
- 代码同步成功,但有部分代码基于之前的操作,可能出现个别子项目未对齐
大部分错误,就是代码未对齐、工具缺失依赖的错误文章来源:https://www.toymoban.com/news/detail-425576.html
5.3.1 代码问题
- 即便repo提示已经更新成功,但也会出现代码未对齐的情况,这个时候,将出现错误的project 子项目,使用楼上 rm -rf 将其删除,重新同步即可
- 例如如下错误
[100% 1/1] out/soong/.bootstrap/bin/soong_build out/soong/build.ninja

13:58:17 soong bootstrap failed with: exit status 1
#### failed to build some targets (21 seconds) ####
szhou@bc04:~/aosp/aosp$
5.3.2 依赖缺失错误
- 经过多个ubuntu版本测试,基本就是缺 libncurses5
sudo apt install libncurses5
5.4 编译成功
- 没想到32核心64线程的服务器,在使用 -j32和 - j64的编译时间,只相差了不到15分钟
- 当然,-j32的时候,我是使用docker编译,也许因此会慢一些,后面再做个对比
