KMM dependency issue in Shared Module

Question

We are creating an app using KMM. But we are facing an issue, kSoap2 Library works fine in the android app but when this library used in Shared Directory of Android Studio, it doesn't work and gives error. The Same thing applies to Calendar. It is also not working, when writing Calendar.getInstance() the error says

Cannot access 'Kotlin.Cloneable'' which is a supertype of 'java.util.Calendar'. Check your module classpath for missing or conflicting dependencies

All your android dependencies should be moved to the androidMain sourceSet from commonMain.

As a general rule in common you can only have dependencies that can compile to all your targets. Since your android dependencies are under the common source set it doesn't really know how to compile those to iOS

Here's an example of using the Android Arch viewmodel: https://github.com/halcyonmobile/MultiplatformPlayground/blob/master/common/src/androidMain/kotlin/com/halcyonmobile/multiplatformplayground/shared/CoroutineViewModel.kt
