wifi判定
val networkInfo: NetworkInfo? = cm.activeNetworkInfo
(networkInfo != null && networkInfo.isConnected
networkInfo.type == ConnectivityManager.TYPE_WIFI))

net判定
val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
val networkCapabilities =
connectivityManager.getNetworkCapabilities(connectivityManager.activeNetwork)
return networkCapabilities?.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
?: false
} else {
val networkInfo: NetworkInfo? = connectivityManager.activeNetworkInfo
return (networkInfo != null && networkInfo.isConnected)
}
API23以上は ConnectivityManagerのactiveNetworkが使えると思うので、そちらを使う。
