Framework学习_2添加product

添加Product

配置文件，类似应用开发中的build.gradle中的渠道包，用于将系统编译成不同的镜像文件

# 模拟器相关的produ文件
build/target 
# 实际硬件相关的product文件
device/

aosp_x86_64-eng:
build/target/borad/generic_x86_64/BroadConfig.mk
build/target/product/AndroidProducts.mk
build/target/product/aosp_x86_64.mk

在device目录下新增厂商/机型目录，如下：

# 产品配置文件
device/xiaomi/pandora/pandora.mk 
# 定义硬件相关的底层特性、变量，当前源码支持的架构、WiFi、摄像头、内核、启动器
device/xiaomi/pandora/BroadConfig.mk
# 执行 lunch 展示的就是该处定义的
device/xiaomi/pandora/AndroidProducts.mk

新增完后 执行lunch命令查看列表是否存在并且正确编译

参考文件：

AndroidProducts.mk

参考build/target/product/AndroidProducts.mk

# 指向产品配置文件（如device.mk或自定义.mk文件）
PRODUCT_MAKEFILES := \
    $(LOCAL_DIR)/pandora.mk \
# 在AndroidProducts.mk中定义，列出所有可用的产品组合（格式为<product_name>-<build_variant>）。
COMMON_LUNCH_CHOICES := \
    pandora-eng \
    pandora-userdebug \
    pandora-user \

pandora.mk

复制 build/target/product/aosp_x86_64.mk，注释了PRODUCT_ENFORCE_ARTIFACT_PATH_REQUIREMENTS := relaxed上下三行

# - compatible property override enabled

BroadConfig.mk

位于device/厂商/设备/目录下，定义硬件相关的配置（如CPU架构、内核路径等）。
