来自文档:

此版本是主要版本更新，包括重大更改.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，否则更新后的库将无法使用:

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 包，您可以执行以下操作:

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

使用 Android Studio 3.2 及更高版本，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.
