Android.mk中遍历所有源文件

最近工作常用到，小结一下

写法1

MY_FILES_PATH := $(LOCAL_PATH) \ $(LOCAL_PATH)/../../Classes MY_FILES_SUFFIX := %.cpp %.c %.cc My_All_Files := $(foreach src_path,$(MY_FILES_PATH), $(shell find "$(src_path)" -type f) ) My_All_Files := $(My_All_Files:$(MY_CPP_PATH)/./%=$(MY_CPP_PATH)%) MY_SRC_LIST := $(filter $(MY_FILES_SUFFIX),$(My_All_Files)) MY_SRC_LIST := $(MY_SRC_LIST:$(LOCAL_PATH)/%=%) LOCAL_SRC_FILES := $(MY_SRC_LIST) #打印编译信息 $(warning 'src_list='$(LOCAL_SRC_FILES))
