为什么 FirebaseUI 日志记录断言 A/FirebaseApp：Firebase API 初始化失败尽管我可以运行应用程序正常？

Question

我想问一下为什么 FirebaseUI 会记录断言 A/FirebaseApp：Firebase API 初始化失败尽管我可以运行应用程序正常？

在我的依赖中，我只使用 compile: 'com.firebaseui:firebase-ui:0.6.2' 没有别的。

我在使用 FirebaseListAdapter 和 FirebaseRecyclerAdapter 的 2 个不同活动中分别使用了 GridView 和 RecyclerView。

但是，我的 android 监视器中总是有这个断言：

10-29 23:38:44.099 25919-25919/com.xenolang.xenolang A/FirebaseApp: Firebase API initialization failure.

您使用的设备或模拟器有旧版本的 Google Play 服务。 FirebaseUI 0.6.2 使用 9.8.0 版的 Firebase API。他们需要最新版本的 Google Play 服务，即 9.8.77。

您的 logcat 输出可能包含与此类似的警告：

W/GooglePlayServicesUtil: Google Play services out of date.  Requires 9877000 but found 9875480
