If you want to use implementation 'com.google.firebase:firebase-database:18.0.0 then you have to do the following:

从文档:

此版本是主要版本更新，其中包含重大更改. 在此版本中，库从Android支持库迁移到Jetpack(AndroidX)库. 除非您在应用中进行以下更改，否则更新的库将无法工作:

This release is a MAJOR version update and includes breaking changes. With this release, libraries are migrated from the Android Support Libraries to the Jetpack (AndroidX) Libraries. The updated libraries will not work unless you make the following changes in your app:

• 将com.android.tools.build:gradle升级到v3.2.1或更高版本.

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.

将compileSdkVersion升级到28或更高版本.

Upgrade compileSdkVersion to 28 or later.

要将其他依赖项迁移到androidx程序包，可以执行以下操作:

To migrate the other dependencies to androidx package, you can do the following:

在Android Studio 3.2及更高版本中，您可以通过从菜单栏中选择重构>迁移到AndroidX ，来快速迁移现有项目以使用AndroidX.

With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.
