背景

在 MacBook Pro M3 Max 上编译 AOSP 的文章中提到了使用 OrbStack 进行 AOSP 项目编译，但是对于代码查看和调试不方便，用了 idea, vscode 的 remote 方式都有些问题，还是选用官方推荐的 Ubuntu 配合 ASfP 的方式更合适。

设备

硬盘 2 TB，源码加编译产物使用了差不多 900GB 多
CPU Intel® Core™ i5 processor 14600KF 24M Cache
GPU INNO3D GEFORCE RTX 4070 SUPER 曜夜OC
RAM 芝奇 幻锋戟 32GB * 2 DDR5 6400
HDD 致态 TiPlus 7100 2TB NVMe M.2 PCIe4.0

编译

配置

针对 Pixel 6 编译，考虑到节省磁盘空间，移除了部分非必要项目。

在 .repo 目录下新增 local_manifests 目录，添加需要移除的项目的配置。后续 repo sync 就不会同步对应移除项目的代码。

3
$ mkdir -p .repo/local_manifests/
$ touch .repo/local_manifests/device_clean.xml
$ touch .repo/local_manifests/jdk_clean.xml

移除非 oriole(Pixel 6) 未使用到的其他 device 项目

调试

导入 ASfP

asfp project

在 android 14 上如果编译的固件类型是 userdebug，发现无法 attach process 进行 debug。
