最近,我无法运行任何适用于
Android的YouTube API演示版.
在实现与YouTube API类有一定依赖关系的第一个活动时,我得到一个ClassNotFoundException.
任何使用YouTube API的应用都会发生这种情况.

我的YouTube应用已更新至4.5.,我在三星galaxy s3 mini上运行JellyBean.
我的手机或Eclipse中是否有任何设置可以丢失？

[解决了！]
很酷我找到了答案.似乎是ADT后期更新中的一个错误.此链接解释了所有内容：https://groups.google.com/d/msg/adt-dev/epOfZbKPFdk/v4a-pTbq1OwJ
或者引用它：
项目右键单击>属性> Java构建路径>订单和出口>检查Android私有库>好
然后项目>清洁…
并重建/运行.
