Android游戏编程

我正在学习如何从中制作Android游戏，但我的应用程序无法运行。我正在三星Galaxy S2上调试，而不是在模拟器上

这是我的日志：

java.lang.RuntimeException:无法实例化活动组件信息{com.example.demandEngine/com.example.demandEngine.MainActivity}:java.lang.ClassNotFoundException:com.example.demandEngine.MainActivity

从控制台：

[2014-03-08 23:12:12 - DemoAndengine] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[ xxx ] cmp=xxxx }

我认为要么我的AndEngine库有问题，要么我导入了不正确的AndEngine

您正在使用eclipse吗？还要检查清单文件中要声明的活动。项目列表中是否有错误？AndEngine或您的项目可以有大红色！或者有不同含义的x。
