Android 12/13 artifact_path_requirements错误 预制apk/预制bootanimation相关framework实战课程答疑

粉丝朋友在学习我的课程内置应用时候，和bootanimation时候，发现如果在Android 12/13 上预制apk时候发现有编译不过情况，报artifact_path_requirements相关错误
具体错误显示如下：

build/make/core/artifact_path_requirements.mk:26: warning:  build/make/target/product/sdk_phone_x86_64.mk produces files inside build/make/target/product/generic_system.mks artifact path requirement. 
Offending entries:
system/app/MyApp/MyApp.apk
In file included from build/make/core/main.mk:1383:
build/make/core/artifact_path_requirements.mk:26: error: Build failed.
00:42:13 ckati failed with: exit status 1

这里乍一看估计99%的人都不知道怎么回事，这里其实可以从提示是可以看出来：
大概是因为新版本artifact_path_requirements有对预装相关东西进行了规则检测，发现system/app/MyApp/MyApp.apk这种预制到system/app的情况属于违规了。
那么具体怎么解决呢？

方法一

通过在github寻找到了一些第三方rom维护者也有遇到类似问题，参考他们解决方案，自己这边再消化后，我的修改如下：

diff --git a/envsetup.sh b/envsetup.sh
index 16873095aa..8c4a8c62e6 100644
--- a/envsetup.sh
+++ b/envsetup.sh

     export ANDROID_TOOLCHAIN=
     export ANDROID_TOOLCHAIN_2ND_ARCH=

即build/envsetup.sh 加上export DISABLE_ARTIFACT_PATH_REQUIREMENTS="true"就可以顺利编译通过不再报artifact_path_requirements错误，这里其实就相当于把新版本编译系统中artifact_path_requirements检测关闭就可以

附一下成功图片：

方法二：

上面修改方式相对有点暴力，没有细粒度的细分，而是一股气把所有的开放了，也有一种细粒度的方法如下：

diff --git a/target/product/telephony_product.mk b/target/product/telephony_product.mk

里面最重要的一个就是

PRODUCT_ARTIFACT_PATH_REQUIREMENT_ALLOWED_LIST +=\
       system/app/MyApp/MyApp.apk \

在这个PRODUCT_ARTIFACT_PATH_REQUIREMENT_ALLOWED_LIST加上相关的白名单既可以

bootanimation预制新方法：

原来8.1使用的Android.mk中进行shell直接拷贝到system/media路径下已经不生效
1、bootanimation下面已经没有了相关的Android.mk了
2、哪怕找到可以执行的Android.mk，编译也会提示没有media路径不存在

这里也针对新版本的预制bootanimation.zip进行讲解

修改patch如下

这里核心就是如下这句

PRODUCT_COPY_FILES += \
   packages/services/Car/car_product/car_ui_portrait/bootanimation/bootanimation.zip:system/media/bootanimation.zip

采用这个PRODUCT_COPY_FILES宏，这个方式相对比较标准
