Android apps were using Android Support library, but in 2018 it was replaced by AndroidX.
Android MAS SDK still uses Android Support library, which is depreciated .
While MAS uses this deprecated library, how can we use MAS SDK with Android X.
Release : 4.2
Component : MOBILE API
The Android Support libraries are not deprecated. It's just that they are not going to have any new development/features.
Any new feature goes into AndroidX branch.
In the case of MAS DK, since we are not using the new features added to AndroidX, it can continue to use support libraries.
It is in our consideration list to migrate to AndroidX, but we don't have a definitive timeline yet.
