Android:如何检查wifi是否已通过身份验证

Question

我的应用程序在 android 中使用 wifi 管理器，但我在以下情况下遇到错误::WIFI 已打开但未通过身份验证(使用我们公司的 wifi 用户名和密码)当时我的应用程序是强制关闭，

我使用的代码是

try{
    if (connectivityManager != null && 
       (connectivityManager.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED) ||
       (connectivityManager.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED))
    { 
        //You are connected, do something online.
        return true;
    }
    else if (connectivityManager.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED ||  
             connectivityManager.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED ) 
    {             
        //Not connected.        
        //Toast.makeText(getApplicationContext(), "You must be connected to the internet", Toast.LENGTH_LONG).show();
        loginTask.myPublishProgress("You must be connected to the internet");
        return false; 
    }   
    }
catch(NullPointerException ae)
   {
        ae.printStackTrace();
        loginTask.myPublishProgress("You must be connected to the internet");

   }
