【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
