【cocos2dx 3.2】2048

打包好的APK：http://pan.baidu.com/share/link?shareid=847502897&uk=185595768

游戏分析请看【Android重制2048】

打包方法：

（1）将工程导入eclipse中(记得将xml文档中调成竖屏模式)

（2）将VS工程中的D:\hello\Card\cocos2d\cocos\2d\platform\android\java\src里的org文件夹拖进eclipse的src

（3）修改eclipse工程中jni文件下的Android.mk文件

参考：http://blog.csdn.net/gf771115/article/details/34414449

（4）打开CMD，运行到VS工程中的proj.android下，执行Build_native.py

（5）成功后重新导入工程到eclipse中

（6）最后导出apk

效果：

        director->setOpenGLView(glview);
    }
	//分辨率适应
	glview->setDesignResolutionSize(268,512,ResolutionPolicy::EXACT_FIT);
   
    director->setDisplayStats(true);

    director->setAnimationInterval(1.0 / 60);
