AndroidJava and setting a BitSet value

Question

Hi I am in a struggle at assigning a BitSet value in a Android Java Object I'm referencing.

I tried with Int, or even to copy the referred value into a AndroidJavaObjects and now I am short of Ideas.

Here is part of my code, I am making a HotSpot manager inside the game itself. I'm debugging with logcat and I am putting a Debug.Log every row to see where the code stops

What I need is to assign AuthAlgorithm to OPEN, without having the BitSet type in C#

Thanks in advance.

         using (AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity"))
         {
             try
             {
                 using (var WifiSetup = activity.Call<AndroidJavaObject>("getSystemService", "wifi"))
                 {
 
                     AndroidJavaObject newConnection = new AndroidJavaObject("android.net.wifi.WifiConfiguration");
 
                     newConnection.Set<string>("SSID", mSSID);
                     
                     newConnection.Set<string>("preSharedKey", mPWD);
 
                     newConnection.Set<bool>("hiddenSSID", false);

                     //THOSE UP HERE WORK!


                     //DOESN'T WORKS LIKE THIS:
                     newConnection.Set<int>("allowedAuthAlgorithms", 0);

                     //DOESN'T WORKS EVEN LIKE THIS (breaks at definition)
                     AndroidJavaObject OPEN = new AndroidJavaObject("android.net.wifi.WifiConfiguration.WifiConfiguration.AuthAlgorithm.OPEN");

  
                     newConnection.Set<AndroidJavaObject>("allowedAuthAlgorithms", OPEN);

                     //THIS DEFINITION WORKS                        
                     AndroidJavaObject allowedAuthAlgorithms = newConnection.Get<AndroidJavaObject>("allowedAuthAlgorithms");

                     //NEITHER THIS ONE WORKS
                     allowedAuthAlgorithms.Call<int>("set", "WifiConfiguration.AuthAlgorithm.OPEN");

//CODE CONTINUES THE REST IS WORKING AND TESTED

I know this is very old but if anyone in the future needs the answer to this, this is how you do it... specifically for an OPEN network.

 using (var allowedKey = new AndroidJavaObject("java.util.BitSet"))
 {
     allowedKey.Call("set", 0);
     wifiConfig.Set("allowedKeyManagement", allowedKey);
 }

Right, next time just check the documentation. BitSet in Java is a class and therefore you can't just set it to an integer. Also the BitSet class can represent a set of bits of arbitrary size. It seems to use an array of bytes internally.

also note that allowed$$anonymous$$ey.Call("set", 0); will just set the bit at index 0 and the rest stays unchanged, If you want to clear all bits (setting all bits to 0) you may want to use the clear method ins$$anonymous$$d.

I've never used the wifi configuration class but i would guess you don't have to create a BitSet yourself. You probably can just manipulate the existing instance. Though i could be wrong about that
