I'm new to android development and am trying to start learning the
basics by decoding a RSS feed. I want to store the appropriate info
(title, link, etc) into
the appropriate corresponding strings. I have the below, which will
search for anything that starts with <t (for title), and store the
corresponding values into a char array. I then search for the end
bracket ('</") and stop storing the information. I then convert the
char array into a string, and toast the string when I press button 1.
My problem is, when I press the button, it toasts a blank box, meaning
that the string is empty. Does anyone have any idea on how to fix
this? Thanks!
My Code:
package rssread.withoutinernet;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class RssReaderNoInternetActivity extends Activity {
Button button1;
Button button2;
Button button3;
String RSS_String = "<?xml version='1.0' encoding='UTF-8'?><rss
xmlns:atom='http://www.w3.org/2005/Atom' xmlns:openSearch='http://
a9.com/-/spec/opensearchrss/1.0/' xmlns:georss='http://www.georss.org/
