Ola, estou usando o AD 3.5 e quando eu adiciono as dependencias appcompat, cardview e design...ele apresenta a msg abaixo.
Error: 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... [GradleCompatible]
o que pode ser?
