kotlinlang

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&lt;Any&gt;`. 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 * !)
