How to detect WiFi tethering state

Question

I want to know how to detect state of WiFi tethering. I\'ve seen an article: Android 2.3 wifi hotspot API But it doesn\'t work! It returns always WIFI_AP_STATE_DISABLED = 1.

Here is the Xamarin C# version if anyone is looking:

    static Method isWifiApEnabledMethod;

    public static bool IsWifiApEnabled ()
    {
        var wifiManager = WifiManager.FromContext (Application.Context);
        if (isWifiApEnabledMethod == null)
        {
            try
            {
                isWifiApEnabledMethod = wifiManager.Class.GetDeclaredMethod ("isWifiApEnabled");
                isWifiApEnabledMethod.Accessible = true; //in the case of visibility change in future APIs
            }
            catch (NoSuchMethodException e)
            {
                Debug.WriteLine ("Can't get method by reflection" + e);
            }
            catch (System.Exception ex)
            {
                Debug.WriteLine ("Can't get method by reflection" + ex);

            }
        }

        if (isWifiApEnabledMethod != null)
        {
            try
            {
                return (bool)isWifiApEnabledMethod.Invoke (wifiManager);
            }
            catch (System.Exception ex)
            {
                Debug.WriteLine ("Can't invoke by reflection" + ex);

            }
        }

        return false;
    }
