NetWorkInfo、connectivityManager.ActiveNetworkInfo 和 .IsConnected 已过时

Question

I have an app that is targeting Android 8.0 (API Level 26 - Oreo) through Android 10.0 (API Level 29 - Q) and the following code is depreciated:

            ConnectivityManager connectivityManager = (ConnectivityManager)GetSystemService(ConnectivityService);
            NetworkInfo activeConnection = connectivityManager.ActiveNetworkInfo;
            bool isOnline = (activeConnection != null) && activeConnection.IsConnected;

If NetworkInfo and anything associated with it is depreciated, what do I use in it's place. I've researched this issue all day and EVERY suggestion I've seen uses functionality that is depreciated (and written in java which is a total mystery to me). So please don't tell me this is a duplicated of some issue already posted somewhere, it's not. Also, if you provide code, please c#.

Answer 1

Although the code is in Kotlin, I hope you will understand whats the alternative.

fun isConnectedToTheInternet(): Boolean {
        val cm = application.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            cm.run {
                cm.getNetworkCapabilities(cm.activeNetwork)?.run {
                    return when {
                        hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                        hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                        hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                        else -> false
                    }
                }
            }
        } else {
            cm.run {
                cm.activeNetworkInfo?.run {
                    if (type == ConnectivityManager.TYPE_WIFI) {
                        return true
                    } else if (type == ConnectivityManager.TYPE_MOBILE) {
                        return true
                    }
                }
            }
        }

        return false
    }

Answer 2

If it can help you or if someone can convert this code to C#.
This code is functional in Kotlin and is not depreciated .

private fun isInternetConnection(): Boolean {
    val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    val capability = connectivityManager.getNetworkCapabilities(connectivityManager.activeNetwork)
    return capability?.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET) ?: false
}

Hoping to have helped you
