最近我無法運行任何Android API的YouTube API演示。 當實例化對YouTube API類具有一定依賴性的第一個活動時，我得到一個ClassNotFoundException。 這發生在任何使用YouTube API的應用程序中。在Android上運行YouTube API演示時未發現類別
我的YouTube應用更新至4.5。+，並且我正在三星Galaxy s3 mini上運行JellyBean。
有沒有我的手機或Eclipse中可能缺少的設置？

酷我找到了答案。似乎是ADT更新後期的錯誤。此鏈接可以解釋這一切：https://groups.google.com/d/msg/adt-dev/epOfZbKPFdk/v4a-pTbq1OwJ
或者引用它：
項目右鍵 - >屬性> Java構建路徑>排序和導出>檢查Android的私家藏書> OK
然後項目>清除。 ..
並重建/運行。
