按这个https://mirrors.bfsu.edu.cn/help/AOSP/ 先下载[aosp-latest.tar](https://mirrors.bfsu.edu.cn/aosp-monthly/aosp-latest.tar)

再解压aosp-latest.tar

repo init -u https://mirrors.bfsu.edu.cn/git/AOSP/platform/manifest -b android-12.0.0_r34 --partial-clone --clone-filter=blob:limit=10M
下载SP1A.210812.016.C2，高通，Google bin驱，解压
https://developers.google.cn/android/drivers#crosshatchsp1a.210812.016.c2

build/envsetup.sh
lunch aosp_crosshatch-userdebug
m
等待编译完成将，将上面两个文件下载下来，放到aosp根目录下
sh ./repo_patch.sh aosp.patch
再全编译
m

等待patch编译完成

adb reboot fastboot
fastboot flashall -w
等待刷机完成

或者直接用我编译好的，链接: https://pan.baidu.com/s/1RbJdK1dF_s1ts2MlHjpIFQ 提取码: sssk

终端切到解压后的目录

export ANDROID_PRODUCT_OUT=`pwd`
adb reboot bootloader
fastboot flashall -w

合规需要检测的方法，参考https://github.com/zhengjim/camille 里的script.js

APP运行在该patch上的截图

自己改的话，推荐使用这样改
