Is it possible to write a function with varargs that calls a Java function with varargs of type Object?

Say, I want a shorter name for Android’s `getString()`:

@NonNull
    public final String getString(@StringRes int resId, Object... formatArgs) {
        return getResources().getString(resId, formatArgs);
    }

How do I write a Kotlin function that just forwards its arguments to this getString?
According to the docs, I should use kotlin.Any!
Android Studio does not even let me add the !.

Using just vararg Any results in IllegalFormatExceptions

A type ending in ! is a platform type. It comes in from Java. You can never define one yourself.

Have you tried the spread operator?
*formatArgs? (note the *)

Doesn’t this imply that I have to pass an array?
So, I need to wrap my vararg params into an array?

[streetsofboston]

fun Resources.myGetString(id: Int, vararg arguments: Any) =
    this.getString(id, *arguments)

(where Resources is the Android Resources class defined in Java)

Thank you. Works fine.
