Adding extra build.prop to Android build system

on

The generation of build.prop is handled by make file build/core/Makefile.

There are a few ways to add a property

  • Use echo commands in build/tools/buildinfo.sh
echo "ro.build.id=$BUILD_ID"
echo "android.os.Build.ID=$BUILD_ID"
  • device/xxxx(OEM)/xxxx(Product)/system.prop
const.window.w=1920
const.window.h=1080
  • Use ADDITIONAL_BUILD_PROPERTIES to add property
ADDITIONAL_BUILD_PROPERTIES:= \
        $(ADDITIONAL_BUILD_PROPERTIES)\
        $(PRODUCT_PROPERTY_OVERRIDES)
  • ADDITIONAL_BUILD_PROPERTIES will also collect PRODUCT_PROPERTY_OVERRIDES
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\
