获取Android手机的Mac地址的工具类

首先添加权限

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

接下来是具体的方法：

public static String getMacAddress(Context context) {
        // 获取mac地址：
        String macAddress = "000000000000";
        try {
            WifiManager wifiMgr = (WifiManager) context
                    .getSystemService(Context.WIFI_SERVICE);
            WifiInfo info = (null == wifiMgr ? null : wifiMgr
                    .getConnectionInfo());
            if (null != info) {
                if (!TextUtils.isEmpty(info.getMacAddress()))
                    macAddress = info.getMacAddress().replace(":", "");
                else
                    return macAddress;
            }
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return macAddress;
        }
        return macAddress;
    }
