PS我已经阅读了那个问题（Firebase Error cannot access zzanb after using play-services-xxx:9.8.00），但我什么都不明白，在我的情况下我需要从我的 build.gradle 文件中添加或删除什么。

You're mixing libraries from old and new Firebase released. Everything from Firebase that you use should be in parity. This line is reference an library from a very old Firebase release (before it became the Firebase platform at Google):
您正在混合发布的新旧 Firebase 库。您使用的 Firebase 中的所有内容都应该相同。这一行引用了一个来自非常旧的 Firebase 版本的库（在它成为 Google 的 Firebase 平台之前）：
compile 'com.firebaseui:firebase-ui:0.6.0'
If you want to use the Firebase-UI library, you should use the new version of itthat matches the version of the main client library you're using. You're using 10.0.1, so according to the table on the Firebase-UI github I just linked, you want this dependency:
如果您想使用 Firebase-UI 库，您应该使用与您正在使用的主客户端库版本相匹配的新版本。您使用的是 10.0.1，因此根据我刚刚链接的 Firebase-UI github 上的表格，您需要此依赖项：
compile 'com.firebaseui:firebase-ui:1.1.1'
Always make sure your Firebase-UI library matches the core Firebase SDK you're using.
始终确保您的 Firebase-UI 库与您使用的核心 Firebase SDK 相匹配。

It looks like in your case Doug'sfix resolved your issue, but we recently encountered the same problem with a different root cause.
在您的情况下，Doug 的修复程序似乎解决了您的问题，但我们最近遇到了具有不同根本原因的相同问题。
In our case, we had configured our IDE project to use JDK8 but failed to check which version of the JDK was in use in the terminal. Because React Native runs Gradle from the command line when you type 'react-native run-android' Gradle was attempting to build using JDK10 which caused obvious issues since Android currently only supports up to JDK8. Once we configured the terminal to use JDK8 the issue was resolved.
在我们的例子中，我们已将 IDE 项目配置为使用 JDK8，但未能检查终端中使用的是哪个版本的 JDK。因为当您键入“react-native run-android”时，React Native 会从命令行运行 Gradle，所以 Gradle 尝试使用 JDK10 进行构建，这导致了明显的问题，因为 Android 目前最多只支持 JDK8。一旦我们将终端配置为使用 JDK8，问题就解决了。
TL;DR: Check what version of the JDK you are using in the terminal.
TL;DR：检查您在终端中使用的 JDK 版本。
