Android首次开机通过设置向导拷贝文件到sdcard目录下

MTK平台机器，首次开机会启动OOBE设置向导，我们可以在此应用中增加一个界面，从/system/目录下拷贝文件到/mnt/sdcard/目录下。

1.首先编译时要将文件从代码路径拷贝到对应的out目录，可以用在mk文件中实现：
方法①：如果文件较少，可以采用逐条拷贝方式，范例如下：

CUR_PATH := vendor/ThirdParty/App/tchip
PRODUCT_COPY_FILES +=  $(CUR_PATH)/bootanimation.zip:system/media/bootanimation.zip  $(CUR_PATH)/multimedia/MP4.mp4:system/media/multimedia/MP4.mp4 

CUR_PATH := vendor/ThirdParty/App/qifei
tchip_files := $(shell ls $(CUR_PATH)/multimedia )
PRODUCT_COPY_FILES += $(foreach file, $(tchip_files),         $(CUR_PATH)/multimedia/$(file):system/media/multimedia/$(file))
