Question

我首先实现系统和引擎多人游戏，然后能够调整所有导入和库并在MOTODEV中运行而没有任何错误，但模拟器“已意外停止”。

您可以看到code here。

模拟器出错：

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

该行说明，您尝试instantiate activity它的名称为MainActivity且它位于com.multiplayerand pakage，但系统找不到任何包含此Component-info的Activity，并且所以java.lang。ClassNotFoundException已经发生了。

我想如果你能解决问题：

检查您的活动名称是否为MainActivity。
检查MainActivity是否在名称为com.multiplayerand的包裹中。
检查您是否在项目的manifest中注册了MainActivity。
