Android机用移动数据流量获取也能获取mac地址的终极方法。(第二种方法)

第一种方法:

(1)设备开通Wifi连接,获取到网卡的MAC地址和IP地址(但是不开通wifi,这种方法获取不到Mac地址,这种方法也是网络上使用的最多的方法)

//根据Wifi信息获取本地Mac

public static void getLocalMacAddressFromWifiInfo(Context context)

{

    WifiManager wifi = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); 

    WifiInfo info = wifi.getConnectionInfo(); 

          String macAdress = info.getMacAddress(); //获取mac地址

int ipAddress = info.getIpAddress();  //获取ip地址    

    String ip = intToIp(ipAddress); 

}

public String intToIp(int i) 

     {       

           return ((i >> 24) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." 

+((i >> 8 ) & 0xFF) + "." + ( i & 0xFF) ;     

}    

这里需要加入permission

 

 

第二种方法:

调用android API NetworkInterface. getHardwareAddress ()
   首先是getLocalIpAddress,获取本地IP地址.

//获取本地IP

public static String getLocalIpAddress()

       try 

                for (Enumeration en = NetworkInterface 

                                .getNetworkInterfaces(); en.hasMoreElements();)

                { 

                     NetworkInterface intf = en.nextElement(); 

                     for(Enumeration enumIpAddr = intf 

                                 .getInetAddresses(); enumIpAddr.hasMoreElements();)

                     { 

                                InetAddress inetAddress = enumIpAddr.nextElement(); 

                                    if (!inetAddress.isLoopbackAddress()

            &&!inetAddress.isLinkLocalAddress())

                                     

                                     return inetAddress.getHostAddress().toString(); 

                                } 

                     } 

                } 

             } catch (SocketException ex)

                       { 

                             Log.e("WifiPreference IpAddress", ex.toString()); 

                       } 

       return null

}


然后,再根据IP地址获取到MAC地址:

public static String getLocalMacAddressFromIp(Context context)

{

     String mac_s= "";

     try {

             byte[] mac;

             NetworkInterface ne =

                      NetworkInterface.getByInetAddress(InetAddress.getByName(getLocalIpAddress()));

             mac = ne.getHardwareAddress();

             mac_s = byte2hex(mac);

             } catch (Exception e) {

                          e.printStackTrace();

                         }

         return mac_s;

     }

public static  String byte2hex(byte[] b)

{

          StringBuffer hs new StringBuffer(b.length);

          String stmp = "";

          int len = b.length;

          for (int n = 0; n < len; n++)

     {

              stmp = Integer.toHexString(b[n] & 0xFF);

              if(stmp.length() == 1){

                  hs = hs.append("0").append(stmp);

      }else {

                  hs = hs.append(stmp);

                   }

          }

          return String.valueOf(hs);

 }

针对获取IP地址的方法,还有一种改进方法,这是是网上运用比较多的,测试表明,该方法获取到了类似fe80::b607:f9ff:fee5:487e..这样的IP地址。注意看这里的IP地址是IPV6的地址形式。所以,一种解决方法是,在上面代码中的最内层的for循环的if语句中对inetAddress进行格式判断,只有其是IPV4格式地址时,才返回值。修改后代码如下:

public String getLocalIpAddress() { 

        try 

              String ipv4; 

                  List  nilist = Collections.list(NetworkInterface.getNetworkInterfaces()); 

              for (NetworkInterface ni: nilist)  

              { 

                 List  ialist = Collections.list(ni.getInetAddresses()); 

                 for (InetAddress address: ialist)

        { 

                         if (!address.isLoopbackAddress() &&                          

                                          InetAddressUtils.isIPv4Address(ipv4=address.getHostAddress()))  

                    {  

                        return ipv4; 

                    } 

                } 

            } 

           } catch (SocketException ex) { 

            Log.e(LOG_TAG, ex.toString()); 

        } 

        return null

    }
