android获取Mac地址和IP地址
获取Mac地址实际项目中测试了如下几种方法: (1)设备开通Wifi连接，获取到网卡的MAC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 String getLocalMacAddressFromWifiInfo(Context context){ WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); WifiInfo info = wifi.getConnectionInfo(); return info.getMacAddress(); } ``` (2)调用Linux的busybox，通过linux命令来获取 [](http://www.cnblogs.com/lijunamneg/archive/2013/03/04/2943146.html) //根据busybox获取本地Mac public static String getLocalMacAddressFromBusybox(){ 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]; } }*/ result = Mac; Log.i("test",result+" result.length: "+result.length()); } return result; } private static 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; } [](http://www.cnblogs.com/lijunamneg/archive/2013/03/04/2943146.html) (3)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 ...
