Hi,
I have a simple java file that fetches a RSS Feed from a webpage and
displays the title tag on the console in eclipse. It works fine.
But now I am trying to use the same class in my Android application and
it's not working. Below is my .java file that's fetching the RSS feed XML:
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.DOMException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class RSSTest {
public static String[] titles;
public static void writeFeed(){
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc =
builder.parse("http://fbrss.com/f/daea930ed6d29773bc07b4e6e74b5c70_7LtWgbABJGOOKCW4pWrI.xml";);
NodeList list = doc.getElementsByTagName("title");
titles = new String[list.getLength()];
for(int i = 1; i<titles.length; i++) {
Element item = (Element) list.item(i);
if(!item.getFirstChild().getNodeValue().contains("Photo"))
titles[i] = item.getFirstChild().getNodeValue();
}
} catch (DOMException e) {
e.printStackTrace();
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
The above file runs fine as a Java application. But I am making an android
app and trying to use the strings fetched in titles[]. I am simply trying
to display the string from let's say titles[1] on the display on a
TextView. Below is my code for Android app:
package com.kaushal.JustRss;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class JustRSSActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
RSS.writeFeed();
String s = RSS.titles[2];
TextView tv = (TextView)findViewById(R.id.textView1);
tv.setText(s);
}
}
When it goes to RSS.writeFeed() line, it goes in to IO Exception.
Any help would be appreciated.
