Could the supported matrix clarify which .NET Android workload and target framework should compile androidx.core:core-splashscreen:1.2.0.3? A minimal binding build against both 1.2.0.2 and 1.2.0.3 would help isolate whether the duplicate classes come from the generated package, a transitive AndroidX version conflict, or a workload compatibility boundary.
