[解决！]
酷我找到了答案。似乎是在后期ADT更新的错误。此链接解释这一切：https://groups.google.com/d/msg/adt-dev/epOfZbKPFdk/v4a-pTbq1OwJ
Cool I found the answer. Seems to be a bug in a late ADT update. This link explains it all: https://groups.google.com/d/msg/adt-dev/epOfZbKPFdk/v4a-pTbq1OwJ
或者引用它：
右键单击项目>属性> Java构建路径>订单和出口>检查Android的私家藏书>确定
Project right-click > Properties > Java Build Path > Order and Export > Check Android Private Libraries > OK
然后项目>清除...
Then Project > Clean...
和重建/运行。
推荐答案
