我真的不确定这里发生了什么。它之前工作正常，然后我将Android sdk版本更改为25，因为我添加了facebook sdk，版本26不支持它。那时候它停止工作了，所以我把所有的东西都回滚到它工作的时候，但现在它不工作了。有什么想法吗？

您不能使用

com.google.android.gms:play services auth:9.0.0

和25.0.0以上的支持库，请参见：

构造函数已被设置为受保护。此类不应公开实例化，但可以通过针对较新API级别的支持库进行扩展

---

而

9.0.0

的构建并没有考虑到这一限制，从而导致了您正在经历的错误。您必须将

play services auth

依赖项更新为最新版本。最新的，也是唯一一个与targeting API 26兼容的版本是。

我这样做了，但它说：解析com.google.android.gms失败：play services auth:11.2.0您是否阅读了我链接的11.2.0发行说明中关于使用

maven.google.com

存储库的说明？
