Unresolved reference for synthetic view when layout is in library module

Question

using Kotlin 1.20.20 (not that it matters, older versions behaves the same)

When layout is in separate library module Android Studio has no problem finding and refer

Answer 1

In an incremental improvement on @pablisco's solution above, in my library I have a file:

// SyntheticExports.kt
@file:Suppress("ClassName")

package com.example.library.synthetic.main

import android.view.TextView
import android.view.View
import android.view.ViewGroup
import kotlinx.android.synthetic.main.common_layout.view.rootLayout as syntheticRootLayout
import kotlinx.android.synthetic.main.common_layout.view.retryButton as syntheticRetryButton

object common_layout {
    object view {
        inline val View.rootLayout: ViewGroup get() = syntheticRootLayout
        inline val View.retryButton: TextView get() = syntheticRetryButton
    }
}

Then on the other module:

// MainActivity.kt
import com.example.library.synthetic.main.common_layout.view.rootLayout
import com.example.library.synthetic.main.common_layout.view.retryButton

rootView.rootLayout.isVisible = true
rootView.retryButton.setOnClickListener { doIt() }

If this issue is ever fixed, I just need to change imports to start with "kotlinx.android" instead of "comp.example.library".
