android:获取本机Mac地址及IP地址方法

原文地址

1、Android  获取本机Mac 地址方法：

  

    需要在AndroidManifest.xml文件中添加权限：    

 <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 获取本机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;
     }
