Android的 - 如果检测WiFi是WEP，WPA，WPA2等编程 [英] Android - detecting if wifi is WEP, WPA, WPA2, etc. programmatically

问题描述

我要寻找在Android编程的方式来确定当前是否我的设备连接的无线网络，来的是安全无论是使用WEP，WPA或WPA2。我试过谷歌搜索，我无法找到一个纲领性的方法来确定这一点。我也看了看TelephonyManager（ http://developer.android.com/参考/安卓/电话/ TelephonyManager.html ），其中还缺乏这种信息。

I am looking for a programmatic way on Android to determine whether the WIFI my device is currently connected to is "secured" using either WEP, WPA, or WPA2. I've tried Google searching and I cannot find a programmatic way to determine this. I've also looked at the TelephonyManager (http://developer.android.com/reference/android/telephony/TelephonyManager.html) which also lacks this information.

谢谢，
Ĵ

推荐答案

有是使用ScanResult对象的方法。

There is a way using the ScanResult object.

事情是这样的：

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
List<ScanResult> networkList = wifi.getScanResults();

//get current connected SSID for comparison to ScanResult
WifiInfo wi = wifi.getConnectionInfo();
String currentSSID = wi.getSSID();

if (networkList != null) {
    for (ScanResult network : networkList)
    {
       //check if current connected SSID
       if (currentSSID.equals(network.SSID)){
        //get capabilities of current connection
        String Capabilities =  network.capabilities;        
        Log.d (TAG, network.SSID + " capabilities : " + Capabilities);

        if (Capabilities.contains("WPA2")) {
           //do something
        }
        else if (Capabilities.contains("WPA")) {
           //do something
        }
        else if (Capabilities.contains("WEP")) {
           //do something
        }
       }
    }
}
