Question

我已经在asp.net中创建了restfull webservices（retun json数据）并在iis.now上部署它我想在android中使用那个webServices但在android中它在模拟器中工作正常但在android设备上却给出了错误。 ..

错误：拒绝与“// http://ipAddress.:6547/”的连接请帮助那个代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.recent_jsonws_map_layout);


}


 public String readJSONFeed(String URL)
 {
        StringBuilder stringBuilder = new StringBuilder();
        HttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(URL);
        try
        {
            HttpResponse response = httpClient.execute(httpGet);
            StatusLine statusLine = response.getStatusLine();
            int statusCode = statusLine.getStatusCode();
            if (statusCode == 200)
            {
                HttpEntity entity = response.getEntity();
                InputStream inputStream = entity.getContent();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                String line;
                while ((line = reader.readLine()) != null)
                {
                    stringBuilder.append(line);
                }
                inputStream.close();
            }
            else
            {
                Log.d("JSON", "Failed to download file");
            }
        }
        catch (Exception e)
        {
            Log.e("readJSONFeed", e.getLocalizedMessage());
        }        
        return stringBuilder.toString();
   }

 public void btnGetWeather(View view)
 { newReadWeatherJSONFeedTask().execute(http://ipAddress.:6547/RestServiceImpl.svc/jsondata/");
 }

}
