Android系统添加build.prop

build.prop的生成是由make系统解析build/core/Makefile完成
有以下几种添加方式

• build/tools/buildinfo.sh中利用echo命令将属性写到build.prop中

echo "ro.build.id=$BUILD_ID"
echo "android.os.Build.ID=$BUILD_ID"

• device/xxxx厂商/xxxx产品/system.props

const.window.w=1920
const.window.h=1080

• 往ADDITIONAL_BUILD_PROPERTIES 中添加属性

ADDITIONAL_BUILD_PROPERTIES:= \
        $(ADDITIONAL_BUILD_PROPERTIES)\
        $(PRODUCT_PROPERTY_OVERRIDES)

• ADDITIONAL_BUILD_PROPERTIES又会收集PRODUCT_PROPERTY_OVERRIDES中定义的属性

ADDITIONAL_BUILD_PROPERTIES:= \  
        $(ADDITIONAL_BUILD_PROPERTIES)\  
        $(PRODUCT_PROPERTY_OVERRIDES)


PRODUCT_PROPERTY_OVERRIDES += \
        ro.build.version.swversion=1.2\
        ro.build.git.version=2.3\
        ro.build.git.addr=/device/dsds\
        ro.build.git.time=1992-6-1\
