activeNetworkInfo.type is deprecated in API level 28

UPDATE

The connectivityManager.activeNetworkInfo is also deprecated in API level 29

Now we need to use ConnectivityManager.NetworkCallback API
or ConnectivityManager#getNetworkCapabilities or ConnectivityManager#getLinkProperties

SAMPLE CODE USING ConnectivityManager#getNetworkCapabilities

private fun isInternetAvailable(context: Context): Boolean {
        var result = false
        val connectivityManager =
            context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            val networkCapabilities = connectivityManager.activeNetwork ?: return false
            val actNw =
                connectivityManager.getNetworkCapabilities(networkCapabilities) ?: return false
            result = when {
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                else -> false
            }
        } else {
            connectivityManager.run {
                connectivityManager.activeNetworkInfo?.run {
                    result = when (type) {
                        ConnectivityManager.TYPE_WIFI -> true
                        ConnectivityManager.TYPE_MOBILE -> true
                        ConnectivityManager.TYPE_ETHERNET -> true
                        else -> false
                    }

                }
            }
        }

        return result
    }

OLD ANSWER

Yes getType() is deprecated in API level 28

Now we need to use Callers should switch to checking NetworkCapabilities.hasTransport(int)

Also getAllNetworkInfo() is deprecated in API level 29

Now we need to use getAllNetworks() instead of getNetworkInfo(android.net.Network) .

getNetworkInfo()

• Returns connection status information about a particular Network.

getAllNetworks()

• Returns an array of all Network currently tracked by the framework.

SAMPLE CODE

fun isWiFiConnected(context: Context): Boolean {
    val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    return if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        val network = connectivityManager.activeNetwork
        val capabilities = connectivityManager.getNetworkCapabilities(network)
        capabilities != null && capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
    } else {
        connectivityManager.activeNetworkInfo.type == ConnectivityManager.TYPE_WIFI
    }
}

        cm?.run {
            cm.getNetworkCapabilities(cm.activeNetwork)?.run {
