Android - 以编程方式检测wifi是否为WEP,WPA,WPA2等

标签: android wifi

我正在寻找Android上的一种程序化方式,以确定我的设备当前连接的WIFI是否已被保护"使用WEP,WPA或WPA2。我已经尝试了Google搜索,我无法找到一种程序化的方法来确定这一点。我还查看了缺少此信息的TelephonyManager(http://developer.android.com/reference/android/telephony/TelephonyManager.html)。

谢谢, Ĵ

使用ScanResult对象有一种方法。

这样的事情:

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
            }
        }
    }
}
