标签： android class noclassdeffounderror

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，它就开始了。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NoClassDefFound。我意识到我在项目中所做的任何新课程都会出现此错误。谁能帮我？我不知道这个错误的任何解决方案..帮助，请...

这是我的班级：

更新：这是我的问题：

<uses-library android:name="com.google.android.maps" />

必须在<application> </application>

首先检查堆栈跟踪。听起来它正在抱怨除了你的新课以外的其他事情。

确保您的Manifest已在<manifest>标记

中声明了该包 
<manifest package="com.ShoppingList" . . . >
