android自动添加文件到android-mk

将

LOCAL_SRC_FILES := hellocpp/main.cpp \  
                   ../../Classes/AppDelegate.cpp \  
                   ../../Classes/HelloWorldScene.cpp 

换成

FILE_LIST := hellocpp/main.cpp    
FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp)    
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)   

---

另外一种方法:

#遍历目录及子目录的函数  
define walk  
    $(wildcard $(1)) $(foreach e, $(wildcard $(1)/*), $(call walk, $(e)))  
endef  
  
#遍历Classes目录  
ALLFILES = $(call walk, $(LOCAL_PATH)/../../Classes)  
FILE_LIST := hellocpp/main.cpp  
#从所有文件中提取出所有.cpp文件  
FILE_LIST += $(filter %.cpp, $(ALLFILES))  
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)
