Android获取MAC地址

获取MAC地址

6.0之前 public static String getMAC(Context context) {    WifiManager manager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);    if (manager == null) {        return null;    }    WifiInfo info = manager.getConnectionInfo();    String address = info.getMacAddress();    return address;}6.0之后public static String getHightMac() throws SocketException{    Enumeration interfaceEnumeration = NetworkInterface.getNetworkInterfaces();    while (interfaceEnumeration.hasMoreElements()){        NetworkInterface networkInterface = interfaceEnumeration.nextElement();        byte[] addr = networkInterface.getHardwareAddress();        if (addr==null || addr.length==0){            continue;        }        StringBuilder buf = new StringBuilder();         for (byte b: addr){             buf.append(String.format("%02X:",b));         }         if (buf.length()>0){             buf.deleteCharAt(buf.length()-1);         }         return buf.toString();    }    return "";}注意：要加权限

如果6.0之前也用第一种方法只会获取到“02:00:00:00:00:00”，第二种获取没有问题“10:D0:7A:E1:FD:22”，可能查看本机设备，字母是小写的，获取是大写，没有关系的，都可以的。
