Lesson 21 Try It

Instead of reading files, I displayed the entries from two RSS feeds to the left and right text areas respectively, using the following doInBackground() method:

Code:

	@Override public String doInBackground(){
		
		StringBuilder result = new StringBuilder();
		SyndFeedInput feedInput;
		feedInput = new SyndFeedInput();

		SyndFeed feed = null;

	    try {
	           feed = feedInput.build(new InputSource(feedURL));
	        }	 
		catch (Exception e) {
	           e.printStackTrace();
		}
 		
		List<SyndEntry> entryList = feed.getEntries();
		
		for (int i = 0; i < entryList.size(); i++) {	        
	             result.append("Title: " + 
                                (entryList.get(i)).getTitle() + 
                                 "\n" +
		    		"Link: " + 
                                 (entryList.get(i)).getLink() +
		    		"\n" + 
		    		"\n");
	    }
		
		return result.toString();
	   
	}

I'm wondering how to do to have the application look for updates and display the new items in the text areas as soon as they are distributed.
