error in getItemList()

Question

In order to fetch the content of website and display it in the android app, which task has to be performed first, is that Webservices, Http Response? i had followed many tutorials and links as given in the stackoverflow people, but still could not complete my task, so lastly followed the link Need a simple tutorial for android/webservice work?, getting error in xml.getItemList() in FirstActivity class. Xml file is

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android1="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<ListView
    android1:id="@+id/listView1"
    android1:layout_width="match_parent"
    android1:layout_height="wrap_content" >
</ListView>

MainActivity code is:

    package com.webservices;

public class FirstActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);

          FetchList fl = new FetchList();
           fl.execute();
           }
   //Always better to use async task for these purposes
    public class FetchList extends asyncTask<Void,Void,Byte>{

        protected String doinbackground(string... urls){
             // this was explained in first step
              Response res = new Response("http://www.google.com");
              String response = res.getResponse();
              XMLParser xml = new XMLParser(response);
               ArrayList<item> itemList = xml.getItemList();
               xml.parse();
          };

        public void execute() {
            // TODO Auto-generated method stub
                }
         }
Response class is:
public class Response {
String get_url, response;
Activity activity;

public Response(String url){
    this.get_url = url;

}

public String getResponse(){
     InputStream in = null;        
      byte[] data = new byte[1000];
        try {
              URL url = new URL(get_url);   
              URLConnection conn = url.openConnection();
              conn.connect();
            /*  conn.*/
              in = conn.getInputStream();
              Log.d("Buffer Size +++++++++++++", ""+in.toString().length());
              BufferedReader rd = new BufferedReader(new InputStreamReader(in),in.toString().length());
              String line;
              StringBuilder sb =  new StringBuilder();
              while ((line = rd.readLine()) != null) {
                    sb.append(line);
              }
              rd.close();
              response = sb.toString();

             in.read(data);
          Log.d("INPUT STREAM PROFILE RESPONSE",response);
            in.close();
        } catch (IOException e1) {
            Log.d("CONNECTION  ERROR", "+++++++++++++++++++++++++++");
            // TODO Auto-generated catch block

            e1.printStackTrace();
        }
        return response;
}

Your question is not very clear. Why do you parse the google index page via an xml parser ?

You want to do :

 protected String doinbackground(string... urls){
    HttpUrlConnection conn = new URL( urls[0] ).openConnection();
    BufferedReader reader = new BufferedReader( conn.getInputStream() );
    String s = reader.readFully();    
};

Or something like this (with exception handling).

I advise you not to use an AsyncTask for networking. Have a look at RoboSpice, it is much better suited for network requests.

i wanted to parse the content of my website and make it displayed in the app, simply for testing i had given google. i had used many tutorials and links which had exception handling, but finally the result is failure. – user1825740 Nov 15 '12 at 08:03
Did you try the code I gave you ? Just surround everything with a try catch, search a bit, log any exception and it should work. – Snicolas Nov 15 '12 at 08:09
i tried by giving that code in try catch block, cleared the errors, but when i run the project the blank empty screen displays without the website content, what may be the problem? – user1825740 Nov 15 '12 at 12:11
return the string s in doInBackground (add an Override annotation to be sure of the spelling). Then in the onPostExecute method of your asyncTask update your ui with the string you receive in parameter – Snicolas Nov 15 '12 at 12:23
