Question

我的应用程序是在android中使用wifi管理器，但是在情况出现的情况下我遇到了错误:: WIFI已打开但是当时我的应用程序没有通过身份验证（使用我们公司的wifi用户名和密码）是强行关闭，

我正在使用的代码是

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");

   }

Answer 1

使用SupplicantState

SupplicantState supState; 
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
supState = wifiInfo.getSupplicantState();

请参阅this answer in stackoverflow

如果COMPLETED - All authentication completed.

Answer 3

不要使用

conectivityManager.getNetworkInfo(0) and getNetworkInfo(1).

而不是使用

用于WiFi

NetworkInfo conectivityManager = connectivity.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

适用于移动网络（3g）

NetworkInfo conectivityManager = connectivity.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

果冻豆的原因会给这样的硬编码带来麻烦。
