Android空点异常错误

我试图使用intent打开一个活动，但出现以下错误

java.lang.NoClassDefFoundError：

我正在使用三个图书馆 1.谷歌播放库 2.滑动菜单库 3.循环柜台图书馆

Logcat

我的java代码

登录 下面是我的滑行活动

提前感谢。

第一个错误Android Null point exception可能表示您在执行代码时没有设置classpath选项。按照此链接了解如何设置类路径

现在,， 如果您使用的是外部jar

将其复制到项目的“libs”文件夹中。Android工具应该完成剩下的工作。 如果要使用的库是工作区中的单独项目

在您的库项目中：进入Properties->Android并选中“Is library”复选框。 在您的应用程序项目中：进入属性->Android，并在同一部分中添加库项目（单击“添加…”）。不要在这里勾选“是图书馆！”！ 这个问题的一些答案是，您需要转到属性->Java构建路径->项目，并在那里添加库项目。对于普通的Java项目，您可以这样做，但Android工具似乎不需要或不使用它

最后，您可能希望确保导出的应用程序中包含lib

---

转到Properties->Java Build Path->Order and Export，确保已选中库。

您的代码在哪里？？？您尚未在清单文件中定义您的活动。。。发布您的manifest.xml文件和该文件的名称。我在manifest中定义了我的活动。我不明白如何做。您的IDE和操作系统是什么？Eclipse和操作系统是windows 7在Eclipse中，您在Eclipse的“窗口>首选项>Java>构建路径”目录下配置类路径。我真的不知道你在做什么，所以我不确定我能更准确地了解你提供的信息。我已经包括了三个库，在“库”选项卡的构建路径目录中，我有以下三个选项1。安卓4.2.2 2私人图书馆3。Android依赖项
