Android SDK 需要 ADT 版本 23 或以上

Android SDK requires ADT version 23 or above

我当时在 Eclipse 中处理一个项目,不幸的是我删除了一些文件并且无法取回它们,所以我最终创建了一个新项目并将我的文件导入回来。发生这种情况时,我现在收到一个错误:

当我尝试更新时,它说它已经更新了。我在我的项目中收到多个编译错误,我不确定发生了什么,因为在我删除文件之前一切正常。

我看到它告诉我找不到 DDMS 文件。这是因为它没有获取我的 SDK 吗?我尝试帮助 -> 安装新软件并执行 ADT,但似乎我已经安​​装了它,因为之前一切正常。

如能就此问题提供帮助proceed/fix,将不胜感激,谢谢!
