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| mappings](/jetpack/androidx/migrate/class-mappings).\n\nAnnotations\n-----------\n\n|-----------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [CoordinatorLayout.DefaultBehavior](/reference/android/support/design/widget/CoordinatorLayout.DefaultBehavior) | *This @interface was deprecated in API level 27.1.0.
