kotlin multiplatform viewbinding Kotlin

Quick question that's been bugging me - I'm stuck on something that should probably be simple... I'm working on a personal project and I'm working on a Kotlin Multiplatform project where I want to implement custom view binding for an Android app. I've defined my view bindings in a separate module and now I am working with an scenario where the bindings are not being recognized in the Android-specific code. I have the following setup: In my shared module, I've defined the view binding like this: ```kotlin class MyCustomViewBinding private constructor(val view: View) { val textView: TextView = view.findViewById(R.id.myTextView) companion object { fun bind(view: View): MyCustomViewBinding { return MyCustomViewBinding(view) } } } ``` In my Android-specific activity, I am trying to use the binding like this: ```kotlin class MainActivity : AppCompatActivity() { private lateinit var binding: MyCustomViewBinding override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) binding = MyCustomViewBinding.bind(findViewById(R.id.my_root_view)) binding.textView.text = "Hello from Multiplatform!" } } ``` However, when I run the app, I get the following behavior: ``` java.lang.IllegalStateException: View not found for the provided ID ``` I've confirmed that `myTextView` exists in `activity_main.xml`. I tried cleaning and rebuilding the project, but the scenario continues. Is there something specific to the Kotlin Multiplatform configuration that I might be missing? I am using Kotlin version 1.7.10 and Gradle 7.0.2. Any guidance on how to resolve this would be greatly appreciated. Am I missing something obvious? Any ideas what could be causing this? I'm working in a Debian environment. I'd love to hear your thoughts on this.
