Also, since lastSegment doesn't have any parameters, I'd replace the function:

fun HttpUrl.lastSegment(): String =
    pathSegments.lastOrNull { it.isNotEmpty() } ?: "/"

by a variable

val HttpUrl.lastSegment: String
    get() = pathSegments.lastOrNull { it.isNotEmpty() } ?: "/"

At the end, for the Java conversion it's the same, but it's shorter to write 😅

by a variable

Yes please do so :)
