This package is part of the
support library which
is no longer maintained.
The support library has been superseded by AndroidX
which is part of Jetpack.
We recommend using the AndroidX libraries in all new projects. You should also consider
migrating existing projects to AndroidX.
To find the AndroidX class that maps to this deprecated class, see the AndroidX
