编译android版本前准备工作，修改Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := cocos2dcpp_shared

LOCAL_MODULE_FILENAME := libcocos2dcpp


FILE_LIST := hellocpp/main.cpp

FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp) 
FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/appcore/*.cpp)
FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/gameMusicEffect/*.cpp)
FILE_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/gameShop/*.cpp) 

LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)  

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../Classes/appcore

LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../Classes/gameMusicEffect

LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../Classes/gameShop


LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static

include $(BUILD_SHARED_LIBRARY)

$(call import-module,cocos2dx)
$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)
$(call import-module,CocosDenshion/android)
$(call import-module,extensions)

关键：LOCAL_SRC_FILES 包含要编译的CPP目录。
LOCAL_C_INCLUDES 据说非必需，下次编译时修改。

Android.mk参考语法
