Android immediately created Pair elements are null

Question

As show in the image, I create a Pair of String but they are null (as shown in the debugger)

What's wrong? I'd really like to avoid littering my project with a reimplementation of Pair<A, B>

Answer 1

Use android.support.v4.util.Pair instead of android.util.Pair

Answer 2

Using androidx.core.util.Pair instead of android.util.Pair should also work with unit tests
