Android 12 平台 [FAQ28467]如何在vendor下建立目录

admin

[DESCRIPTION]
有客户需求在vendor下建立目录。
[SOLUTION]
这是一个示例：
在alps-mp-s0.mp1-V8.26版本以在vendor下创建dummy举例，主要是在创建vendor.img的过程中创建dummy文件夹：

1. build/make：
   
2. diff --git a/core/Makefile b/core/Makefile
   
3. index 2d56edb9ee..720c3e13b1100644
   
4. --- a/core/Makefile
   
5. +++ b/core/Makefile
   
6. @@ -3103,6+3103,7@@ BUILT_VENDORIMAGE_TARGET := $(PRODUCT_OUT)/vendor.img
   
7. define build-vendorimage-target
   
8. $(call pretty,"Target vendor fs image: $(INSTALLED_VENDORIMAGE_TARGET)")
   
9. @mkdir-p $(TARGET_OUT_VENDOR)
   
10. +@mkdir-p $(TARGET_OUT_VENDOR)/dummy
    
11. @mkdir-p $(vendorimage_intermediates) && rm -rf
    
12. $(vendorimage_intermediates)/vendor_image_info.txt
    
13. $(call generate-image-prop-dictionary,
    
14. $(vendorimage_intermediates)/vendor_image_info.txt,vendor,skip_fsck=true)
    
15. PATH=$(INTERNAL_USERIMAGES_BINARY_PATHS):$PATH \

复制代码

Test：
rootfs下的vendor实际是挂载的vendor.img所在分区，而非vendor.img的内容直接存放在rootfs下的vendor中：

1. # ls vendor/
   
2. app bin build.prop dummy etc firmware lib lib64 lost+found odm odm_dlkm
   
3. overlay priv-app res vendor_dlkm
