Android开发中获取本机Mac地址和IP地址的方法

1、Android  获取本机Mac 地址方法：

  

    需要在AndroidManifest.xml文件中添加权限：   

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

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

 

1. public String getLocalMacAddress() { 
2.         WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
3.         WifiInfo info = wifi.getConnectionInfo(); 
4.         return info.getMacAddress(); 
5.     } 

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：

  

1. public String getLocalIpAddress() { 
2.         try { 
3.             for (Enumeration<NetworkInterface> en = NetworkInterface 
4.                     .getNetworkInterfaces(); en.hasMoreElements();) { 
5.                 NetworkInterface intf = en.nextElement(); 
6.                 for (Enumeration<InetAddress> enumIpAddr = intf 
7.                         .getInetAddresses(); enumIpAddr.hasMoreElements();) { 
8.                     InetAddress inetAddress = enumIpAddr.nextElement(); 
9.                     if (!inetAddress.isLoopbackAddress()) { 
10.                         return inetAddress.getHostAddress().toString(); 
11.                     } 
12.                 } 
13.             } 
14.         } catch (SocketException ex) { 
15.             Log.e("WifiPreference IpAddress", ex.toString()); 
16.         } 
17.         return null; 
18.     }
