Android中的InetAddress

如何在 android中打印网站的IP地址？我可以运行inetaddress并使用Netbean中的system.out.println()打印它.以下是我的示例编码.

public String getHostAddress () {
        InetAddress addr=null;
        try {
            addr= InetAddress.getByName("www.google.com");
        }

        catch (UnkNownHostException E) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            }
        return addr.getHostAddress();
    }

它总是显示不幸的是,你的程序已经停止.
可能知道有没有办法在Android中获取被访问网站的IP地址？
