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] 
    DalvikVM[localhost:8631]    
        Thread [<1> main] (Suspended (exception RuntimeException))  
            ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2585  
            ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2679   
            ActivityThread.access$2300(ActivityThread, ActivityThread$ActivityRecord, Intent) line: 125 
            ActivityThread$H.handleMessage(Message) line: 2033  
            ActivityThread$H(Handler).dispatchMessage(Message) line: 99 
            Looper.loop() line: 123 
            ActivityThread.main(String[]) line: 4627    
            Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]  
            Method.invoke(Object, Object...) line: 521  
            ZygoteInit$MethodAndArgsCaller.run() line: 868  
            ZygoteInit.main(String[]) line: 626 
            NativeStart.main(String[]) line: not available [native method]  
        Thread [<6> Binder Thread #2] (Running) 
        Thread [<5> Binder Thread #1] (Running)

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:)

Unable to resolve superclass of Lcom/zardtechnologies/mrsnakey/MrSnakey; (15)

这是您的应用程序失败的关键。

我建议将 AndroidGame 和 Game 这两个类移动到与 MrSnakey (com.zardtechnologies.mrsnakey) 相同的包中并尝试。在加载 MrSnakey 时，Dalvik 无法链接您的超类。
