eclipse cocos2dx项目，出现错误

E:/Acocos2d-x/cocos2d-1.0.-x-0.11./MyBilliard/android/jni/../../Classes/HelloWorldScene.cpp:: undefined reference to `GameLayer::GameLayer()'
E:/Acocos2d-x/cocos2d-1.0.-x-0.11./MyBilliard/android/jni/../../Classes/HelloWorldScene.cpp:: undefined reference to   

原因是android的nkd编译需要将每个cpp尽心进行声明

进入jni-->Classes目录下的Android.mk

LOCAL_SRC_FILES := AppDelegate.cpp \

　　　　　　　　　　　HelloWorldScene.cpp  

修改成如下：

LOCAL_MODULE_FILENAME := libcocos2dcpp

MY_CPP_LIST := $(wildcard $(LOCAL_PATH)/*.cpp)
MY_CPP_LIST += $(wildcard $(LOCAL_PATH)/hellocpp/*.cpp)
MY_CPP_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp)

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

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