大家好，我是编程新手，最近借用了Mario Zechner的“Beginning Android Games”一书。他告诉我如何创建一个名为mr nom的游戏。我遵循了每一条指令，并将名字改名为mrsnakey。
我的logcat错误如下：

哦，另一个注意事项我搜索了网络，很多人说要调试。我调试了它，我得到了这个：
Mr.Snakey [Android Application]
DalvikVM[localhost:8631]
Thread [<1> main] (Suspended (exception RuntimeException))
ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2585

有关如何阅读本文的任何提示？只有
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]
ActivityThread$H(Handler).dispatchMessage(Message) line: 99
只有这些给了我一个说“附加来源”的方框
感谢阅读！ 感谢给予的任何帮助：）
答案 0 :(得分：0)
Unable to resolve superclass of Lcom/zardtechnologies/mrsnakey/MrSnakey; (15)
这是您的应用失败的关键所在。
我建议将两个类的AndroidGame和Game移动到与MrSnakey（com.zardtechnologies.mrsnakey）相同的包中并尝试。在加载MrSnakey时，Dalvik如何无法链接你的超级班级。
