    I have two methods that will try to start the WiFi hotspot on the android device so that others can connect and play the game. The problem is both method have problems and don't work.

    The first method:
    Code (CSharp):
    1.  
    2. public void ConnectWiFi()
    3. {
    4.     try
    5.     {
    6.  
    7.         using (AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic("currentActivity"))
    8.         {
    9.             using (var wifiManager = activity.Call("getSystemService", "wifi"))
    10.             {
    11.                 AndroidJavaObject wifiConfiguration = new AndroidJavaClass("android.net.wifi.WifiConfiguration");
    12.                 wifiConfiguration.Set("SSID", meSSID); // string
    13.                 wifiConfiguration.Set("preSharedKey", mePassword); // string
    14.                 wifiManager.Call("setWifiApEnabled", wifiConfiguration, enabled);
    15.             }
    16.         }
    17.     }
    18.     catch (System.Exception E)
    19.     {
    20.         T.text += "\nE - " + E.Message;
    21.         T.text += "\n\t" + E.StackTrace+"\n";
    22.     }
    23. }
    24.  
    it crashes the game and I can't debug it. here is the log for it:

    I filtered it to what I thought would be helpful...
    The Second method:
    Code (CSharp):
    1.  
    2. public void ConnectWiFiHardWay()
    3. {
    4.    try
    5.    {
    6.  
    7.        using (AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic("currentActivity"))
    8.        {
    9.            using (var wifiManager = activity.Call("getSystemService", "wifi"))
    10.            {
    11.  
    12.                using (AndroidJavaObject classObj = wifiManager.Call("getClass"))
    13.                {
    14.                    using (AndroidJavaObject wifiConfiguration = new AndroidJavaObject("setWifiApEnabled"))
    15.                    {
    16.                        wifiConfiguration.Set("SSID", meSSID); // string
    17.                        wifiConfiguration.Set("preSharedKey", mePassword);
    18.                        using (AndroidJavaObject wifiCfgClass = wifiConfiguration.Call("getClass"))
    19.                        {
    20.                            using (AndroidJavaObject booleanObj = new AndroidJavaObject("java.lang.Boolean"))
    21.                            {
    22.                                using (AndroidJavaObject booleanClass = booleanObj.Call("getClass"))
    23.                                using (AndroidJavaObject methodObj = classObj.Call("getMethod", "setWifiApEnabled", wifiCfgClass, booleanClass))
    24.                                {
    25.                                    methodObj.Call("invoke", wifiManager, wifiConfiguration, enabled);
    26.                                }
    27.                            }
    28.                        }
    29.                    }
    30.                }
    31.            }
    32.        }
    33.    }
    34.    catch (System.Exception E)
    35.    {
    36.        T.text += "\nH - " + E.Message;
    37.        T.text += "\n\t" + E.StackTrace+"\n";
    38.    }
    39.  
    this one throws an exception that says setWifiApEnabled Cannot be found I can post the complete error text if that helps.
