我首先实现了系统和引擎多人游戏，然后能够调整所有导入和库并在没有任何错误的情况下运行MOTODEV，但是模拟器“意外停止”。

您可以在此处查看代码。

模拟器上的错误：

请注意日志中的这一行： 

Unable to instantiate activity ComponentInfo{com.multiplayerand/com.multiplayerand.MainActivity}: java.lang.ClassNotFoundException: com.multiplayerand.MainActivity in loader dalvik.system.PathClassLoader

那行说，你试图instantiate activity它的名字是MainActivity，它会在com.multiplayerand包中，但是系统找不到任何具有这个组件信息的活动，所以 java.lang。ClassNotFoundException已经发生。

我想你可以解决问题，如果你：

  • 检查您的活动名称是否为MainActivity。
  • 检查是否MainActivity在带有 name 的包中com.multiplayerand。
  • 检查您是否在manifest项目中注册了 MainActivity。
