我有一个奇怪的问题。我在一个项目中有一个类，当我运行它时，它开始正常。我把这个类放在我的项目中（我有一些包和一些类），我把它放在AndroidManifest中，但是当我运行时，我得到了NoClassDefFound。我意识到我的项目中有任何新课程，我都会遇到这个错误。谁能帮我？我不知道这个error..Help，请任何解决方案..我在我的项目中创建的任何新课程，我得到NoClassDefFound
这是我的课：

UPDATE：这里是我的问题：

必须在<application> </application>
安置自己的代码和错误日志的包，请。 – 2011-05-14 13:23:10
请张贴您的清单。 – MByD 2011-05-14 13:32:37
我提到这不是第一次当我得到这个错误。在另一个类中（它像这样扩展了MapActivity）我也得到了这个错误。看起来，我不能在我的项目中看到这些类。我不明白哪里可以解决问题，因为我已经把Manifest的地图权限放进去了，我在xml中输入了密钥...... – Gaby 2011-05-14 13:47:52
