# Action

| This package is part of the Android [support library](https://developer.android.com/topic/libraries/support-library) which is no longer maintained. The support library has been superseded by [AndroidX](https://developer.android.com/jetpack/androidx) which is part of [Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](https://developer.android.com/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class
