| title: "使用 ASfP 阅读和调试 AOSP" | ||
| date: 2024-05-01 10:24:01 +0800 | ||
| categories: android | ||

|
|
||
| ## 引言 | ||
|
|
||
| 在 [MacBook Pro M3 Max 上编译 AOSP](https://shumxin.github.io/2024/04/05/build-aosp-in-mackbook-pro-m3-max/) 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```](https://developer.android.com/studio/platform) 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。 | ||
|
|
||
| ```.repo``` 目录新增 ```local_manifests``` 目录，添加需要移除的项目的配置。后续 ```repo sync``` 就不会进行代码同步。 | ||
|
|
||
| ```bash | ||
| $ 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 | ||
|
|
||
| ```device_clean.xml``` | ||
|
|

|
|
||
| 移除部分 ```jdk``` | ||
|
|
||
| ```jdk_clean.xml``` | ||
|
|
||
| ```xml | ||
| <?xml version="1.0" encoding="UTF-8"?> | ||
| <manifest> | ||

| </manifest> | ||
| ``` | ||

||
| ### 耗时 | ||
|
|
||
| ```-j``` 指定了 12，其他任务并行执行电脑也不感觉到卡顿。耗时 1小时 10 分钟完成。 | ||
|
|
||
| ```bash | ||
| $ make otapackage -j12 WITH_DEXPREOPT=false | ||
| ``` | ||
|
|
||
