For Kotlin, you can easily just use the URL.openStream() method to read and save your file in your directory.

If you want to do more fancier, like background threads. You should checkout Elye's article on Medium.

private fun downloadVcfFile() {
    CoroutineScope(Dispatchers.IO).launch {
        val url = "https://srv-store5.gofile.io/download/JXLVFW/vcard.vcf"
        val path = "${Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)}/contacts.vcf"

        URL(url).openStream().use { input ->
            FileOutputStream(File(path)).use { output ->
                input.copyTo(output)

                val file = File(path)
                file.createNewFile()
                onMain { saveVcfFile(file) }
            }
        }
    }
}
