Should we use android.util.Pair or androidx.core.util.Pair?

Question

I just migrated to AndroidX, and noticed there's a new class called androidx.core.util.Pair.

I was wondering, going forward, should I use android.util.Pair or androidx.core.util.Pair?

Answer 1

Yes, it is better to use androidx.core.util.Pair, from the docs:

(September 21, 2018)

This is the stable release of Support Library 28.0.0 and is suitable for use in production. This will be the last feature release under the android.support packaging, and developers are encouraged to migrate to AndroidX.
