Question, I have

fun getString(@StringRes resId: Int, vararg formatArg:Any) = activity()?.getString(resId, formatArg)

So I can call this instead of needing the context in every screen. But it doesn't correctly format, and it just displays lang.Object@zlkjdf

If I change the method to Java, it works though. Is some conversion going wrong from Kotlin to Java?

A vararg Any parameter is compiled into an Array<Any>. That's the issue here: when passing the array to another vararg function, the array is passed as-is, hence the lang.Object which is the string representation of the array in Java (not its content as a string!)
In such case, you need to spread that array:
getString(resId, *formatArg) (mind the * !)

Thank you!
