[Android Studio] Version 28 (intended for Android Pie and below) is the last version of the legacy support library, so we recommend that you migrate to AndroidX libraries when using Android Q and moving forward.

Version 28 (intended for Android Pie and below) is the last version of the legacy support library, 
so we recommend that you migrate to AndroidX libraries when using Android Q and moving forward. 
The IDE can help with this: Refactor > Migrate to AndroidX... 
Inspection info:There are some combinations of libraries, or tools and libraries, 
that are incompatible, or can lead to bugs. 
One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).
