每次在调试器中启动程序时，我都会收到ActivityThread.performLaunchActivity（ActivityThread $ ActivityRecord，Intent）错误。该程序甚至不会启动！任何帮助将不胜感激！我对这种环境很新。如果您需要更多信息/代码来帮助我，请告诉我。

看来ProyectoActivity（java.lang.ClassNotFoundException）类对于Dalvik是不可见的。它可能是这个类没有编译（或）不在dalvik正在寻找的类路径中。这是你的主要活动吗？如果是这样，请确保此活动的包名称与AndroidManifest.xml中定义的包名称匹配

尝试弄清楚你是否正确地导入了类，似乎调试器找不到它。
