| This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The Constraint Layout support library has been superseded by the[AndroidX Constraint Layout library](https://developer.android.com/reference/androidx/constraintlayout/classes), which is part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.
