可能重复：
应用程序意外停止：mrsnakey
大家好，我对编程很陌生，最近借了 Mario Zechner 的《Beginning Android Games》一书。他教我如何创建一个名为 mr nom 的游戏。我遵循每一条指令，并将 mr nom 重命名为 mrsnakey。
我的logcat错误如下：

哦，另一条笔记我在网上搜索了很多人说要调试。我调试了它，我得到了这个：
Mr.Snakey [Android Application]

关于如何阅读这篇文章的任何提示？只要
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框，上面写着“附加来源”
谢谢阅读！感谢提供的任何帮助:)
