android:獲取本機Mac地址及IP地址方法

原文地址

1、Android  獲取本機Mac 地址方法：

  

    需要在AndroidManifest.xml文件中添加權限：    

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

  

public String getLocalMacAddress() {
        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        WifiInfo info = wifi.getConnectionInfo();
        return info.getMacAddress();
    }

 

2、Android 獲取本機IP地址方法： 

  

public String getLocalIpAddress() {
        try {
            for (Enumeration<NetworkInterface> en = NetworkInterface
                    .getNetworkInterfaces(); en.hasMoreElements();) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration<InetAddress> enumIpAddr = intf
                        .getInetAddresses(); enumIpAddr.hasMoreElements();) {
                    InetAddress inetAddress = enumIpAddr.nextElement();
                    if (!inetAddress.isLoopbackAddress()) {
                        return inetAddress.getHostAddress().toString();
                    }
                }
            }
        } catch (SocketException ex) {
            Log.e("WifiPreference IpAddress", ex.toString());
        }
        return null;
    }
