獲取Mac地址：

[java] view plaincopy
  1. public String getLocalMacAddress() {  
  2.         String Mac=null;  
  3.         try{  
  4.

  8.                 FileInputStream fis = new FileInputStream(path);  
  9.                 byte[] buffer = new byte[8192];  
  10.                 int byteCount = fis.read(buffer);  
  11.                 if(byteCount>0)

  14.                 }  
  15.             }

  19.                 path="sys/class/net/eth0/address";  
  20.                 FileInputStream fis_name = new FileInputStream(path);  
  21.                 byte[] buffer_name = new byte[8192];  
  22.                 int byteCount_name = fis_name.read(buffer_name);

  26.                 }  
  27.             }  
  28.             Log.v("daming.zou***eth0**mac11**", ""+Mac);  
  29. //          String path="sys/class/net/eth0/address";

  50.                 return "";  
  51.             }  
  52.         }catch(Exception io){  
  53.             Log.v("daming.zou**exception*", ""+io.toString());  
  54.         }  
  55.           
  56.         Log.v("xulongheng*Mac", Mac);  
  57.         return Mac.trim();  
  58. //      WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);  
  59. //      WifiInfo info = wifi.getConnectionInfo();  
  60. //      if (info.getMacAddress() != null) {  
  61. //          return info.getMacAddress().toString();  
  62. //      }   
  63.     }  

獲取Ip：

[java] view plaincopy
  1. public String GetHostIp() {  
  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.                         && InetAddressUtils.isIPv4Address(inetAddress  
  11.                                 .getHostAddress())) {  
  12.                     if (!inetAddress.getHostAddress().toString()  
  13.                             .equals("null")  
  14.                             && inetAddress.getHostAddress() != null) {  
  15.                         return inetAddress.getHostAddress().toString().trim();  
  16.                     }  
  17.                 }  
  18.             }  
  19.         }  
  20.     } catch (SocketException ex) {  
  21.         Log.e("WifiPreference IpAddress", ex.toString());  
  22.     }  
  23.     return "";
