Android中的InetAddress

概述如何在 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.getByN 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？

解决方法 只是,

它是你在URL上的错误,只需更正它..

“www.Google.com”您的网址中有4个w …

并添加Use-Permission< uses-permission androID：name =“androID.permission.INTERNET”>
在您的AndroID应用程序的清单文件中..

这个是正确的..

addr = InetAddress.getByname(“www.Google.com”);

编辑：使用AsyncTask进行网络 *** 作

String netAddress = null; try  {   netAddress = new NetTask().execute("www.Google.com").get();  }  catch (Exception e1)   {    e1.printstacktrace();   }

而这一个是NetTask类..

public class NetTask extends AsyncTask<String,Integer,String>    {        @OverrIDe        protected String doInBackground(String... params)        {            InetAddress addr = null;            try            {                addr = InetAddress.getByname(params[0]);            }            catch (UnkNownHostException e)            {                            e.printstacktrace();            }            return addr.getHostAddress();        }    }
