オンラインかオフラインか

タイトルの意味のままです

kotlin.kt
private fun isOnline(): Boolean {
        val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        val networkInfo = connectivityManager.activeNetworkInfo
        return networkInfo?.isConnected == true
    }

オンラインならtrueオフラインならfalseが返ってきます
