scan wifi using AndroidJavaObject

hi . I want to scan wifi by using AndroidJavaObject.

I can get ssid with this code :

  AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
         var wifiManager = activity.Call<AndroidJavaObject>("getSystemService", "wifi");
         debug1.text = wifiManager.Call<AndroidJavaObject>("getConnectionInfo").Call<string>("getSSID");

I want to return ListArray from java but I dont know how to do it!!

see this document and compare "getScanResults" and "getConnectionInfo". sorry for poor english.
