The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n|
