注意，ALL_DEFAULT_INSTALLED_MODULES描述的文件除了在build/core/main.mk文件中定义的模块文件之外，还包含以下这些文件： 1. 通过PRODUCT_COPY_FILES定义的要拷贝到目标设备上去的文件
[plain] view plain copy
![]() ![]()
- unique_product_copy_files_pairs :=
- $(foreach cf,$(PRODUCT_COPY_FILES), \
- $(if $(filter $(unique_product_copy_files_pairs),$(cf)),,\

5. 由于使用了BSD、GPL和Apache许可的模块而必须在发布时附带的Notice文件

- ifeq ($(ONE_SHOT_MAKEFILE),)
- <span style="color:#FF0000;"><strong>ALL_DEFAULT_INSTALLED_MODULES += $(installed_notice_html_gz)</strong></span>

6. 用来验证OTA更新的ZS文件
