now here is the problem, you are using different versions in dependencies of gradle So change this
现在问题来了，你在gradle的依赖项中使用了不同的版本所以改变这个
compile 'com.google.firebase:firebase-database:10.0.0'
testCompile 'junit:junit:4.12'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.firebase:firebase-storage:9.2.1'
compile 'com.android.support:multidex:1.0.0'
to this
对此
compile 'com.google.firebase:firebase-database:10.0.1'
testCompile 'junit:junit:4.12'
compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.android.support:multidex:1.0.0'
one more thing is that now com.firebae:firebase-client-androidis deprecated so you need to replace it with com.google.firebase:firebase-database:10.0.1and here is the documentation for that https://firebase.google.com/support/guides/firebase-android
还有一件事是现在com.firebae:firebase-client-android已弃用，因此您需要将其替换com.google.firebase:firebase-database:10.0.1为https://firebase.google.com/support/guides/firebase-android

If you are seeking solution for react-native project, make sure there is same version used among different modules and replace "+" with some latest available version.
如果您正在寻找 react-native 项目的解决方案，请确保不同模块之间使用相同的版本，并将“+”替换为一些最新的可用版本。

I have faced similar problem while implementing native ad and killed almost 4 hours...
我在实施原生广告时遇到了类似的问题并杀死了近 4 个小时......
At last i have figured out that there are different com.google.android.gms:play-services-ads version in different module('17.1.1' and '12.0.0').
最后我发现在不同的模块中有不同的 com.google.android.gms:play-services-ads 版本（'17.1.1' 和 '12.0.0'）。
After changing all version to 17.1.1 it solved my problem.
将所有版本更改为 17.1.1 后，它解决了我的问题。

Most of the time the problem is in the gradle. I had a similar problem until I changed firebase-(storage/auth/database) build gradle for module app to be the same for e.g. ( com.google.firebase:firebase-storage:16.1.0,com.google.firebase:firebase-auth:16.1.0, com.google.firebase:firebase-database:16.1.0)
大多数时候问题出在gradle中。我遇到了类似的问题，直到我将模块应用程序的 firebase-(storage/auth/database) 构建 gradle 更改为与例如（ com.google.firebase:firebase-storage:16.1.0,com.google.firebase:firebase -auth:16.1.0, com.google.firebase:firebase-database:16.1.0)
