特定的，针对自己硬件平台的Android系统，比如不使用缺省的out/target/prodect/generic目录，
本文档简单介绍了这个编译系统，并做一个针对自己硬件平台的Android，
这部分工作主要是由Android源代码中的Vendor文件夹来实现，如果该文件夹不成立，自己可以在Android源代码的根目录下建立该文件夹，这个文件夹里面存放特定的文件，比如自己板子上的3G驱动，WIFI驱动，自己的应用程序，都可以放在这里。提取文件系统的时候，可以把这个文件夹里面的东东放到文件系统里面，这样用户可以清晰的看到你的板子特有的功能。
PRODUCT_NAME := <first_product_name> PRODUCT_DEVICE := <board_name>
will already be set to # the directory containing this file. # # This file may not rely on the value of any variable other than # LOCAL_DIR; do not use any conditionals, and do not look up the # value of any variable that isn't set in this file or in a file
that # it includes. # PRODUCT_MAKEFILES := / $(LOCAL_DIR)/first_product_name.mk /
:= false # TARGET_USE_GENERIC_AUDIO := true
# rild.libargs=-d /dev/ttyS0
kernel ifeq ($(TARGET_PREBUILT_KERNEL),) TARGET_PREBUILT_KERNEL := $(LOCAL_PATH)/kernel endif # file := $(INSTALLED_KERNEL_TARGET) ALL_PREBUILT += $(file) $(file): $(TARGET_PREBUILT_KERNEL) | $(ACP) $(transform-prebuilt-to-target) # # no boot loader, so we
don't need any of that stuff.. # LOCAL_PATH := vendor/<company_name>/<board_name> # include $(CLEAR_VARS) # # include more board specific stuff here? Such as Audio parameters. #
Overrides PRODUCT_NAME := <second_product_name> PRODUCT_DEVICE := <board_name> 目前为止，你已经有了两个新product，<first_product_name>和<second_product_name>，都属于<company_name>。 验证一下一个product是否配置正确，运行 . build/envsetup.sh make PRODUCT-<first_product_name>-user 在/out/target/product/<board_name>目录下，你可以看到生成的二进制文件。
