android获得mac和ip .

 

1、Android  获取本机Mac 地址方法：

  

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

view plaincopy to clipboardprint?

1. <span style="font-family:Arial;BACKGROUND-COLOR: #ffffff"> </span><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />  

<span style="font-family:Arial;BACKGROUND-COLOR: #ffffff"> </span><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

 

view plaincopy to clipboardprint?

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： 

  

view plaincopy to clipboardprint?

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. }
