Android应用程序立即崩溃

我已经试着让它工作了将近一个星期。我已经准备好了许多线程，并尝试了我能找到的一切。我不明白为什么我的应用程序根本不能工作。我已经尝试了emulator和android手机。

这是您的错误：

11-12 13:31:45.008:E/AndroidRuntime（13055）：由以下原因引起：java.lang.ClassNotFoundException:com.example.StickmanRevolution.activity.MainActivity位于loader dalvik.system.PathClassLoader[/data/app/com.example.StickmanRevolution-2.apk]

---

Android找不到类

com.example.StickmanRevolution.activity.MainActivity

。确保您的类位于正确的包中，并且名称完全匹配（包括大小写）。

还要确保您的AndroidManifest.xml中的类名称正确。哇，我犯了一个愚蠢的错误。清单上的名字是对的，我只是把实际的名字打错了。谢谢你的帮助。
