<2>解决方案。
这个问题困扰了我快一天，因为以前运行别人的工程是没有问题的，还以为没有加上main.h和main.cpp导致的。
解决问题的方法就是，在Android.mk中：
LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp \
在后面加上要编译的.cpp文件文件
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := game_shared
LOCAL_MODULE_FILENAME := libgame
LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp \
../../Classes/StartLayer.cpp \
../../Classes/BasicLayer.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static cocosdenshion_static cocos_extension_static
include $(BUILD_SHARED_LIBRARY)
$(call import-module,CocosDenshion/android) \
$(call import-module,cocos2dx) \
$(call import-module,extensions)
搞定！！！
然而最佳解决方案是用下面的Android.mk文件，什么都不用加，就OK了，不管里面有.cpp文件多少编译了。
- LOCAL_PATH := $(call my-dir)
- include $(CLEAR_VARS)
- LOCAL_MODULE := game_shared
- LOCAL_MODULE_FILENAME := libgame
- FILE_LIST := hellocpp/main.cpp
- FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp)
- LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)
- LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
- LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static cocosdenshion_static cocos_extension_static
- include $(BUILD_SHARED_LIBRARY)
- $(call import-module,CocosDenshion/android) \
- $(call import-module,cocos2dx) \
- $(call import-module,extensions)
