We have to use BUILD_PREBUILT instead of PRODUCT_COPY_FIES,

because SMALLER_FONT_FOOTPRINT is only available in Android.mks.

LOCAL_PATH := $(call my-dir)

create symlink for given font

$(1): new font $(2): link target

should be used with eval: $(eval $(call ...))

define create-font-symlink $(PRODUCT_OUT)/system/fonts/$(1) : $(PRODUCT_OUT)/system/fonts/$(2) @echo "Symlink: $$@ -> $$<" @mkdir -p $$(dir $$@) @rm -rf $$@ $(hide) ln -sf $$(notdir $$<) $$@

this magic makes LOCAL_REQUIRED_MODULES work

ALL_MODULES.$(1).INSTALLED := \ $(ALL_MODULES.$(1).INSTALLED) $(PRODUCT_OUT)/system/fonts/$(1) endef

We may only afford small font footprint.

$(eval $(call create-font-symlink,DroidSans.ttf,Roboto-Regular.ttf)) $(eval $(call create-font-symlink,DroidSans-Bold.ttf,Roboto-Bold.ttf))

On space-constrained devices, we include a subset of fonts:
