android获取mac地址

【Android】获取Mac地址【1】

(1) 调用android 的API: NetworkInterface. getHardwareAddress ()

该API的level为9,只有android 2.3以上才有该接口

(2) 调用java 的方法: nbtstat/arp

一般android不支持这两个命令

(3) 调用Android的API: WifiManager

权限:

1
"android.permission.ACCESS_WIFI_STATE" >

代码:

1

5
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
 
WifiInfo info = wifi.getConnectionInfo();
 
return info.getMacAddress();

这个是设备开通Wifi连接,获取到网卡的MAC地址

(4) 调用Linux的busybox

          if (Mac.length()> 1 ){
              Mac = Mac.replaceAll( " " , "" );
              result = "" ;
              String[] tmp = Mac.split( ":" );
              for ( int i = 0 ;i
                  result +=tmp[i];
              }
          }
          Log.i( "test" ,result+ " result.length: " +result.length());           
      }
      return result;
  }  
 
  
  public String callCmd(String cmd,String filter) {  
      String result = "" ;  
      String line = "" ;  
      try {
          Process proc = Runtime.getRuntime().exec(cmd);
          InputStreamReader is = new InputStreamReader(proc.getInputStream());  
          BufferedReader br = new BufferedReader (is);  
          
          //执行命令cmd,只取结果中含有filter的这一行
          while ((line = br.readLine ()) != null && line.contains(filter)== false ) {  
              //result += line;
              Log.i( "test" , "line: " +line);
          }
          
          result = line;
          Log.i( "test" , "result: " +result);
      }  
      catch (Exception e) {  
          e.printStackTrace();  
      }  
      return result;  
  }

 

这个需要设备支持busybox工具

(5)查询记录了MAC地址的文件“/proc/net/arp”

需要有这个文件,并且记录了相应的内容
