I have a function like this:
public final GoogleSignInOptions.Builder requestScopes(Scope var1, Scope... var2) { }

I can call .requestScopes(scope1, scope2, scope3) without any problem.

How can I translate a list of Scopes to call this function. I tried using only an Array , a List , to pass the first element and then a list. But nothing worked. Seems like I have to pass the expanded list. How can I achieve this when my list of scopes is stored inside a List<Scope> ?

Thanks!

you need to prefix an array with “*”, e.g. requestScopes(scope1, *arrayOfScopes)

[araqnid]

and you can convert a List to an Array with toTypedArray: requestScopes(scope1, *(listOfScopes.toTypedArray()))

So it’s necessary to pass the first scope alone?

[araqnid]

well, the method prototype you quoted there has separate (Scope,Scope…) args, so yes.

That’s what I thought, double checking. Thanks a lot! 🙂

(presumably to solve overload ambiguity)

I’d have to ask Google about this one 🤔
