                                                     defStyle: Int = androidx.appcompat.R.attr.titleTextStyle)

    }

    private fun init(attrs: AttributeSet?) {

How to resolve this crash and fix it so it never occurs

Answer 1

try this with implementation of all constructors, should work

class CustomMediumTextView : AppCompatTextView {

    constructor(context: Context) : super(context) {
        init(context, null)
    }

    constructor(context: Context, attrs: AttributeSet?) : super(context, attrs) {
        init(context, attrs)
    }

    constructor(context: Context, attrs: AttributeSet?, style: Int) : super(context, attrs, style) {
        init(context, attrs)
    }

    private fun init(context: Context, attrs: AttributeSet?) {
        if (attrs != null) {
            val myTypeface = ResourcesCompat.getFont(context, R.font.roboto_medium)
            this.typeface = myTypeface
        }
    }
}
