【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:

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

代码:

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

   /* 
     *****************************************************************
     *                       子函数:获得本地MAC地址
     *****************************************************************                        
    */    
    public String getMacAddress(){   
        String result = "";     
        String Mac = "";
        result = callCmd("busybox ifconfig","HWaddr");
        
        //如果返回的result == null,则说明网络不可取
        if(result==null){
        	return "网络出错,请检查网络";
        }
        
        //对该行数据进行解析
        //例如:eth0      Link encap:Ethernet  HWaddr 00:16:E8:3E:DF:67
        if(result.length()>0 && result.contains("HWaddr")==true){
        	Mac = result.substring(result.indexOf("HWaddr")+6, result.length()-1);
        	Log.i("test","Mac:"+Mac+" Mac.length: "+Mac.length());
        	
        	if(Mac.length()>1){
        		Mac = Mac.replaceAll(" ", "");
        		result = "";
        		String[] tmp = Mac.split(":");
        		for(int i = 0;i<tmp.length;++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
