How to write Android RSS parser

Important!
If you are writing code for Android 4+ platform use this RSS Reader modification – Android AsyncTask RSS Reader. It seems that in Android 4+ all network activities needs to be encapsulated using AsyncTask (thx Duke! – comment)

In this tutorial we are going to show You how to write Android RSS parser application. Topics that we are going to talk about are: XML parsing, connecting to the network displaying data in the form of clickable list.

If You don’t have an Android Development Environment Installation see how You can easily set it up. Tutorial is available here.

We are going to begin by generating a project. To do this follow those steps:

  • Right click in the Package Explorer window
  • Select New and then Android Project
  • Enter a Project name
  • Click Next
  • Select a platform on which You are going to run Your application
  • And Click Next
  • Now enter your application package name
  • And Click Finish

Now we are going to write some code, the RssItem class. The very first class we’re going to create will be a representation of an “Item”. The “Item” is a name of a Tag containing the Element according to RSS specification which contains the article’s attributes like URLs, publish dates, topics, categories, tags etc.

RssItem.java

package com.itcuties.android.reader.data;
/**
 * This code encapsulates RSS item data.
 * Our application needs title and link data.
 *
 * @author ITCuties
 */
public class RssItem {
	// item title
	private String title;
	// item link
	private String link;
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String getLink() {
		return link;
	}
	public void setLink(String link) {
		this.link = link;
	}
	@Override
	public String toString() {
		return title;
	}
}

So we’ve got the class which represents data gathered from our RSS channel. Because our data is structured as an XML document, we will use an SAX parser to be able to retrieve XML items. SAX is a stream parser. So we will create a handler which reacts on individual events, like opening and closing tags. So let’s write the next class – RssParserHandler.

RssParseHandler.java

package com.itcuties.android.reader.util;
import java.util.ArrayList;
import java.util.List;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
import com.itcuties.android.reader.data.RssItem;
/**
 * SAX tag handler. The Class contains a list of RssItems which is being filled while the parser is working
 * @author ITCuties
 */
public class RssParseHandler extends DefaultHandler {

	// List of items parsed
	private List<RssItem> rssItems;
	// We have a local reference to an object which is constructed while parser is working on an item tag
	// Used to reference item while parsing
	private RssItem currentItem;
	// We have two indicators which are used to differentiate whether a tag title or link is being processed by the parser
	// Parsing title indicator
	private boolean parsingTitle;
	// Parsing link indicator
	private boolean parsingLink;

	public RssParseHandler() {
		rssItems = new ArrayList();
	}
	// We have an access method which returns a list of items that are read from the RSS feed. This method will be called when parsing is done.
	public List<RssItem> getItems() {
		return rssItems;
	}
	// The StartElement method creates an empty RssItem object when an item start tag is being processed. When a title or link tag are being processed appropriate indicators are set to true.
	@Override
	public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
                   if ("item".equals(qName)) {
			currentItem = new RssItem();
		} else if ("title".equals(qName)) {
			parsingTitle = true;
		} else if ("link".equals(qName)) {
			parsingLink = true;
		}
	}
	// The EndElement method adds the  current RssItem to the list when a closing item tag is processed. It sets appropriate indicators to false -  when title and link closing tags are processed
	@Override
	public void endElement(String uri, String localName, String qName) throws SAXException {
		if ("item".equals(qName)) {
			rssItems.add(currentItem);
			currentItem = null;
		} else if ("title".equals(qName)) {
			parsingTitle = false;
		} else if ("link".equals(qName)) {
			parsingLink = false;
		}
	}
	// Characters method fills current RssItem object with data when title and link tag content is being processed
	@Override
	public void characters(char[] ch, int start, int length) throws SAXException {
		if (parsingTitle) {
			if (currentItem != null)
				currentItem.setTitle(new String(ch, start, length));
		} else if (parsingLink) {
			if (currentItem != null) {
				currentItem.setLink(new String(ch, start, length));
				parsingLink = false;
			}
		}
	}
}

Now let’s write a piece of code responsible for launching our SAX parser. This class will process the RSS stream.

RssReader.java

package com.itcuties.android.reader.util;
import java.util.List;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import com.itcuties.android.reader.data.RssItem;

/**
 * Class reads RSS data.
 * @author ITCuties
 */
public class RssReader {
	// Our class has an attribute which represents RSS Feed URL
	private String rssUrl;
	/**
	 * We set this URL with the constructor
	 */
	public RssReader(String rssUrl) {
		this.rssUrl = rssUrl;
	}
	/**
	 * Get RSS items. This method will be called to get the parsing process result.
	 * @return
	 */
	public List<RssItem> getItems() throws Exception {
		// At first we need to get an SAX Parser Factory object
		SAXParserFactory factory = SAXParserFactory.newInstance();
		// Using factory we create a new SAX Parser instance
		SAXParser saxParser = factory.newSAXParser();
		// We need the SAX parser handler object
		RssParseHandler handler = new RssParseHandler();
		// We call the method parsing our RSS Feed
		saxParser.parse(rssUrl, handler);
		// The result of the parsing process is being stored in the handler object
		return handler.getItems();
	}
}

Next piece of code is going to display our RSS parsing results in the form of a clickable list. We need to write a class that implements OnItemClickListener.

ListListener.java

package com.itcuties.android.reader.listeners;
import java.util.List;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import com.itcuties.android.reader.data.RssItem;
/**
 * Class implements a list listener.
 * @author ITCuties
 */
public class ListListener implements OnItemClickListener {
	// Our listener will contain a reference to the list of RSS Items
	// List item's reference
	List<RssItem> listItems;
	// And a reference to a calling activity
	// Calling activity reference
	Activity activity;
	/** We will set those references in our constructor.*/
	public ListListener(List<RssItem> aListItems, Activity anActivity) {
		listItems = aListItems;
		activity  = anActivity;
	}

	/** Start a browser with url from the rss item.*/
	public void onItemClick(AdapterView parent, View view, int pos, long id) {
		// We create an Intent which is going to display data
		Intent i = new Intent(Intent.ACTION_VIEW);
		// We have to set data for our new Intent
        i.setData(Uri.parse(listItems.get(pos).getLink()));
	    // And start activity with our Intent
		activity.startActivity(i);
	}
}

Next thing to do is to add a List View to our application layout. You can achieve that by:

  • Expanding the res folder in the package explorer section and navigating to layout directory
  • Clicking on the main.xml which describes the application layout
  • Removing the default layout
  • Adding a List View from the Composite section

Next step is to put all the things together. We are going to code our activity.

ITCutiesReaderAppActivity.java

package com.itcuties.android.reader;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import com.itcuties.android.reader.data.RssItem;
import com.itcuties.android.reader.listeners.ListListener;
import com.itcuties.android.reader.util.RssReader;

/**
 * Main application activity.
* @author ITCuties
*/
public class ITCutiesReaderAppActivity extends Activity {
	/**
	 * This method creates main application view
	 */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		// Set view
		setContentView(R.layout.main);
		try {
			// Create RSS reader
			RssReader rssReader = new RssReader("http://www.itcuties.com/feed/");
			// Get a ListView from main view
			ListView itcItems = (ListView) findViewById(R.id.listMainView);
			// Create a list adapter
			ArrayAdapter adapter = new ArrayAdapter<RssItem>(this,android.R.layout.simple_list_item_1, rssReader.getItems());
			// Set list adapter for the ListView
			itcItems.setAdapter(adapter);
			// Set list view item click listener
			itcItems.setOnItemClickListener(new ListListener(rssReader.getItems(), this));
		} catch (Exception e) {
			Log.e("ITCRssReader", e.getMessage());
		}
	}
}

The application code is ready, but there is one last thing to enable our application to work on the network… The right Permission settings. You will find these in the AndroidManifest.xml. Follow those steps:

  • Open AndroidManifest.xml
  • Click the Permissions tab
  • Click Add and select Uses Permissions
  • Find and select the android.permission.INTERNET permission

That’s all.

You can download all the codes in the form of Eclipse project here.

You can install this application from here.

    Thank’s for the tutorial, very simple and help me parsing my blog’s feed. Just information, your script in the video are different with the text below it. Maybe you can fix it :)

    I have a question. for this feed, i want use custom listview where in a row there are image and textview. How i can get aech title so ican put that in a textview in my custom listview. i tried ti get RssItem.getTitle but it doesn’t work.

    When i use rssReader,getItems, all the title form the feed show up in one row. Sorry if my english not well. Hope you understand my question and can give me some solution

    Thanks

      Hi Sutadi. It’s nice to hear that our tutorial helped you. If You want to code a ListView displaying an image and some text in a row check out our latest tutorial http://www.itcuties.com/android/how-to-get-running-process-list-and-traffic-statistics/, you might find it useful.

      As for the rssReader.getItems() method it returns a List of RssItems. This class implements toString() method so, in some cases when this method is called behind the scenes you might get a string representation of the list. Don’t know how do you use it but it might happen.

      As for the getTitle method of RssItem class our RSS feed is in version 2.0 and we didn’t have any problems with parsing title. Please check if there is a title tag present in Your feed or does it contain any value.

      Cheers,
      itcuties

    Hello! I’m Taiwanese!

    Similarly, my english is not sufficient proficient, so I hope you can understand what I say, thank you very much ^^

    My problem is that if I want to gain the image tag content , do I use this same concepts (RssParseHandler class)

    to get it and show on my new Activity?

    Because my experience is not ample, so can you give me some guides? I’ll very appreciate you ><

      Hi Shinmin!
      According to W3 an image is a tag that contains url, title and link tags.
      You can use the same concept as we show in this tutorial. You need to modify RssParseHandler so that when it reaches an image tag it sets some kind of flag indicating that now an image tag is being parsed. Next thing is to modify startElement method to parse sub elements of an image tag but only when that flag is set. Image URL is placed in the url tag.
      When You have an image url in your hands use something like this:

      	ImageView imgView=(ImageView)findViewById([YOUR_IMAGE_VIEW_ID]);
	imgView.setImageURI(Uri.parse([RSS_IMAGE_URL]));

      Hope that helps. Let us know about the results. Best of luck.

      Hi Daniel,
      Does your development device on which you run this app has an GSM modem support?
      Did you set android.permission.INTERNET for the application?
      Does our feed link work in your browser?
      Do other RSS feeds work with our code?

      Send us your code to team[at]itcuties[dot]com. We’ll try to figure it out.

    Can you please make an example how to include descriptions in the app itself? So the content of 1 item will show up on a different / new “page”?

      Hi Jordi.
      You need to modify RssParseHandler class to get the description tag value. Do it the same way as the title tag is being processed. Modify RssItem class to hold item’s description data as well.
      Next create a simple view that contains TextView. Create an activity that uses this new view. Set TextView value with the value passed to this activity.
      To read values passed to the activity use this code:

      Bundle bundle = getIntent().getExtras();
String value = bundle.getString("[YOUR_KEY_HERE]");

      Next you need to modify onItemClick method of the ListListener class. You need to start your new activity here and pass a description value.

      Intent intent = new Intent(activity, YourNewActivity.class);
intent.putExtra("[YOUR_KEY_HERE]", listItems.get(pos).getDescription());
activity.startActivity(intent);

          Try this modifications on your RssParseHandler.java

          1. Add private boolean parsingDescription;
          2. In the startElement method change

          else if ("description".equals(qName)){
	parsingLink = true;
}

          to

          else if ("description".equals(qName)){
	parsingDescription = true;
}

          3. In the endElement method change

          else if ("description".equals(qName)){
	parsingLink = true;
}

          to

          else if ("description".equals(qName)){
	parsingDescription = true;
}

          4. In the characters method add

          else if (parsingDescription) {
	if (currentItem != null)
		currentItem.setDescription(new String(ch, start, length));
}

          Take care.

              It’s a pleasure to help you :)
              Just add android:name="android.intent.action.MAIN" (don’t add android:name="android.intent.category.LAUNCHER") configuration (the same way as it is done in ITCutiesReaderAppActivity) to your ItemDescriptionActivity definition.
              Have a nice evening ;)

      Hi Daniel,
      This is almost the exact same solution that we have talked about with Jord. The difference is that you need to get content:encoded tag contents from the RSS feed.

    Hi,

    Great to see very helpful articles here. Great job !!

    I am a beginner in Android programming. I have a food blog (Blogger) and trying to make an app for the same.
    As I am a novice , please bear with my simple (or silly ;) ) and basic questions :) :)
    I have a few questions regarding converting my food blog to app.

    1. Making an app of my blog means I need to get the RSS feed of my blog, parse it and display the data ina good format in my app. Is this the correct method?

    2. Does the RSS feed contain all the blog data? Or does it show only for a certain period?

    3. Can I access the blogger widgets such as Popular posts, Post Categories etc in my app? Or how can I show them in app ? Does the feed has such data?

    4. Should my app connect to the blog for displaying data? Then it won’t serve the purpose of an app rt?????
    So does that mean my app should display the data only from the RSS feed and give “Go to Blog” as an option?

    5. I haven’t seen any food blog as an app to view as example. Are there any such apps?

    Please help me…

    Thanks in advance…

      Hi,
      Ad.1. and 2. Not really. The best way is to connect to WordPress XML-RPC API. Take a look at this solution – http://code.google.com/p/wordpress-java/. Your RSS channel might contain a configured number of items but remember the more items are there the slower channel loads. Mainly RSS channel is being read by RSS Reader applications. You should keep it that way.

      Ad.3. You can read latest data from the RSS feed. If you want to read popular posts use this wordpress-java library that was mentioned above.

      Ad.4. You can get posts data from the WordPress XML-RPC API and display them in the app.

      Ad.5. Don’t know any “food blog” apps as well

      Take care.

        Thanks a lot for your prompt response.
        But one question I have is I have the blog in Blogger and not WordPress.
        So will there be API’s for Blogger as well? I will check it out as well. :)
        Thanks again for taking time to reply.
        I tried your parsing code and it is so easy to understand and implement.

      Hi Neema,
      We have just downloaded this tutorial project from http://download.itcuties.com/android-rss-reader/ITCutiesReaderApp.zip.
      After importing it to Eclipse and running on the Virtual Device 4.1 with API Level 16 and GSM Modem Support everything works fine.
      This application also runs on Android 4.0.4. It was tested on the phisical device.
      Can you please tell us exactly where is the problem in your case?

        Hi, thanks for responding so quick.
        I used your code and ran it on android emulator with o.s 2.3.3 and 2.2 and everything worked fine with no problem at all.
        but when I used your code and ran it on emulator with o.s 4.0 or 4.2 it didn’t work. so I searched stackoverflow and they said we should use to line of code to make it work. and codes are:

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

        and wow ,it worked on android 4.0 or jelly bean (4.2) perfectly but some people say this way is not logical.
        I don’t know, but as long as this code works for me ,I’m happy unless I find out this has something unappropriated to do with security.

        what do you think?

          Hi Neema,
          by calling this code

          StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

          you are disabling detection of all the available resource usage events. Our code only uses network interface. Maybe there is a problem with loading RSS contents duo to network problems. Can’t really tell couse we can run our code on every platform you mentioned.

          You could try calling permitNetwork method instead of the permitAll. We are curiouse if this will give you the same effect.

      Hi Andrey,

      to play a video from URL use this code

      VideoView video = (VideoView)findViewById(R.id.videoView);
video.setVideoPath("VIDEO-URL");
video.start();

      You need to parse the enclosure tag attribute url and store it in the RssItem object. Next modify the ListListener.onItemClick method. In this method start a new activity. This new acitvity needs to have a VideoView element. Use the above code in the acitvitiesonCreate method.

      We have done some tests with your videos. The M4V format is not supported by the Android – http://developer.android.com/guide/appendix/media-formats.html

          To read tag attribute try this modification of the parser class:

          public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        if ("item".equals(qName)) {
            currentItem = new RssItem();
        } else if ("title".equals(qName)) {
            parsingTitle = true;
        } else if ("link".equals(qName)) {
            parsingLink = true;
        } else if ("enclosure".equals(qName)) {
            // Get tags attributes number
            int attrsLength = attributes.getLength();
            for (int i=0; i<attrsLength; i++) {
               String attrName = attrs.getQName(i);  // attribute name
               if ("url".equals(attrName))   // This tag has only one attribute but it is better to check it name is correct
                   currentItem.setVideoURL(attrs.getValue(i));
        }
    }

          Add a videoURL attribute to the RssItem class and appropriate access methods.

    Hello,

    Thank you for such a great tutorial. In the video it was mentioned that performance could be improved for this RSS parser. From what I have read online (new to android development), I think using the AsyncTask function could help as the RSS item data could be read in the background on a different thread. However this is where I get stuck. I have tried a number of attempts to get it working, but with no luck. Would you please be able to set me in the right direction? Your support is appreciated.

    Kind regards

    Really cute I have to admit! a little distracting but I gave my best to learn and it was helpful. Thank you very much!

    in regards to the question I think for the optimization we have to work a bit on the adapter.
    we can have separate adapter class extending ArrayAdapter and then in the getView method check if the row has been initialized before and exist or it’s == null. then if it was null inflate a view for it. Using Asynctask also could be helpful for the whole experience.
    and if this is not the case then I can’t wait to hear it.

    Again Thank you for the great tutorials, great quality of sound, picture and codes.

    Is there a way to get the title and description of the feed (i.e if the feed is a podcast, I want to get the title and description of the podcast) The thing I want to is to be able to “subscribe” to different feeds, show them in a list, and when I click on one it should then show the individual items (what the code does now). Also, do you guys have a tutorial and how to add all this info to a database?, so that we don’t have to load the info every time we launch app

      Hi Asif,

      are you lounching our code without any changes?
      You are reading and parsing itcuties RSS channel? If not check if you RSS XML is valid.
      It seems that Android 2.1 had a bug which resulted in the error that you are ending with. Check here: http://code.google.com/p/android/issues/detail?id=4286. This bug was fixed in Froyo 2.2 so maybe you should try to change the project library to 2.2+… Right click your project, then pick Properties, then Android. In the Project Build Target section pick a target platform which is over the 2.1 specification. Rebuild and rerun your application.
      Hope this helps. Let us know about the results.

      Take care,

    Hi,

    i copied your (written, not video!) tutorial but its not working for me :(. My app only shows blanko page with no entries. Thats weird because when I started yours it works. I also have that Internet-Permission.

    The only difference in Code i have is this line:
    ” i.setData(Uri.parse(((Rssitem) listItems.get(pos)).getLink())); ”

    I had to do a Cast because “object” had no “getLink()”. Anyway, it makes no sense to me how yours is working but mine not with the same code =(

        Hi Duke,
        thanks for your comment. There was an error in our code snippets published on the site – video and the code that can be downloaded was ok. The type of the List data collection used to store RSS items needs to be changed from “List” to “List<RssItem>”. This way you don’t need to perform the cast where you get an item from the items list.
        i.setData(Uri.parse(listItems.get(pos).getLink())); is ok now :)

        As for the lowering the android:minSdkVersion value you have extended number of platforms that your application can run on.
        Are there any major differences in org.xml.sax.* package implementation between the API 7 and API 17 versions? Maybe there are, and this is why while using API 17 version the URL doesn’t parse correctly.
        Where you parsing our RSS channel or some other channel? Maybe there are some “strange” signs in the URL that you are parsing and this is why it doesn’t parse at all (with API v.17).

        Take IT easy,

          What do you mean by change from List to List?
          Anyway, if I run the app with API17 instead of API 7 logcat tells me: “Couldn´t open http://www.itcuties.com/feed/” which seems to be the reason why I got no results.

              Just for your interest: I found the reason :)

              It seems since Android 4.0 you have to encapsulate network activities (especially in MainActivitiy). I solved this by using AsyncTask (which you already had done according to one of your comments to other users, thx again, that helped me ;) )

              Hi Jose,
              If you want to handle parsing errors “in the parser” all you need to do is implement error or fatalError methods in your parse handler class which extends DefaultHandler. So in our example code this should look like this:

              RssParseHandler.java

              package com.itcuties.android.reader.util;

import java.util.ArrayList;
import java.util.List;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.helpers.DefaultHandler;

import android.util.Log;

import com.itcuties.android.reader.data.RssItem;

/**
 * SAX tag handler
 * 
 * @author ITCuties
 *
 */
public class RssParseHandler extends DefaultHandler {

	private List<RssItem> rssItems;
	
	// Used to reference item while parsing
	private RssItem currentItem;
	
	// Parsing title indicator
	private boolean parsingTitle;
	// Parsing link indicator
	private boolean parsingLink;
	
	public RssParseHandler() {
		rssItems = new ArrayList<RssItem>();
	}
	
	public List<RssItem> getItems() {
		return rssItems;
	}
	
	@Override
	public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
		if ("item".equals(qName)) {
			currentItem = new RssItem();
		} else if ("title".equals(qName)) {
			parsingTitle = true;
		} else if ("link".equals(qName)) {
			parsingLink = true;
		}
	}
	
	@Override
	public void endElement(String uri, String localName, String qName) throws SAXException {
		if ("item".equals(qName)) {
			rssItems.add(currentItem);
			currentItem = null;
		} else if ("title".equals(qName)) {
			parsingTitle = false;
		} else if ("link".equals(qName)) {
			parsingLink = false;
		}
	}
	
	@Override
    public void warning(SAXParseException e) throws SAXException {
		Log.e("warning","Hello warning");
		// Custom warning handling here...
    }

    @Override
    public void error(SAXParseException e) throws SAXException {
        Log.e("error","Hello error");
        // Custom error handling here...
    }

    @Override
    public void fatalError(SAXParseException e) throws SAXException {
    	Log.e("fatalError","Hello fatalError");
    	// Custom fatalError handling here...
    }
	
	@Override
	public void characters(char[] ch, int start, int length) throws SAXException {
		// Debug the incoming contents
		Log.d("characters", new String(ch, start, length));
		
		if (parsingTitle) {
			if (currentItem != null)
				currentItem.setTitle(new String(ch, start, length));
		} else if (parsingLink) {
			if (currentItem != null) {
				currentItem.setLink(new String(ch, start, length));
				parsingLink = false;
			}
		}
	}
	
}

              Surprised that warning, error and fatalError do nothing special? We were surprised that those methods are not called by the Android when there is something wrong with the XML stream being parsed. We were testing it on 2.2 and 4.2 platforms. Does anyone know if there is some BUG maybe and those method are not called? … Let us know…
              Anyway… We came up with a HOT fix. All you need to do is get rid of the characters that are invalid and crash the parsing process. Here is our new RssReader code.

              RssReader.java

              package com.itcuties.android.reader.util;

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.net.URL;
import java.util.List;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import com.itcuties.android.reader.data.RssItem;

/**
 * Class reads RSS data.
 * 
 * @author ITCuties
 *
 */
public class RssReader {
	
	private String rssUrl;

	/**
	 * Constructor
	 * 
	 * @param rssUrl
	 */
	public RssReader(String rssUrl) {
		this.rssUrl = rssUrl;
	}

	/**
	 * Get RSS items.
	 * 
	 * @return
	 */
	public List<RssItem> getItems() throws Exception {
		// SAX parse RSS data
		SAXParserFactory factory = SAXParserFactory.newInstance();
		SAXParser saxParser = factory.newSAXParser();

		RssParseHandler handler = new RssParseHandler();
		
		// FIX: Invalid characters FIX here - start
		// Create the URL to the RSS resource
		URL rssURL = new URL(rssUrl);
		// Open an input stream to the rss channel
		InputStream rssInputStream = rssURL.openStream();
		// This is the buffer for the valid RSS contents
		StringBuffer rssContents = new StringBuffer();
		// Buffer to read bytes
		int byteRead = -1;
		// Read bytes one by one from the RSS input stream until there is something to read
		while ((byteRead = rssInputStream.read()) != -1) {
			// Convert byte being read to char
			char charRead = (char)byteRead;
			// If the sign being read is invalid then don't add it to the resulting valid RSS contents buffer
			if (charRead != '’' && charRead != '“') // This are the two problematic characters in your case
				rssContents.append(charRead);
		}
		
		// Create the valid rss input stream from the StringBuffer using ByteArrayInputStream
		InputStream rssValidInputStream = new ByteArrayInputStream(rssContents.toString().getBytes());
		// Parse RSS XML that contains ONLY VALID characters
		saxParser.parse(rssValidInputStream, handler);
		// FIX: Invalid characters FIX here - end
		
		// Old line
		//saxParser.parse(rssUrl, handler);
		
		return handler.getItems();
		
	}
}

              Hope this helps. Take care and take IT easy ;)

                  you mean that description tag has < ![CDATA[ Description text ]]> element?

                  You can call this code to get the description contents.

                  String content = new String(ch, start, length);
content = content.replaceAll("<!\\[CDATA\\[", "");
content = content.replaceAll("]]>", "");

    would you be able to provide any hints on who to do this

      Hi Bubba,

      Try replaceAll method of the String class.
      Here is the example:

      System.out.println("Test:Test:Test".replaceAll("\\:", "."));

      Results in:

      Test.Test.Test

      Cheers,

      This code parses only one RSS feed at a time. You can modify it to parse any number of feeds. Just keep one list of RssItem elements in the activity and call the RssReader getItems method for each feed. Append this method results to the list of the RssItems you keep in the acitvity.
      If you want to display something more than just an item’s title please refer to our other tutorial where we display process information in a list with an image and a text. You will need to implement the your ListAdapter. Watch our tutorial – http://www.itcuties.com/android/how-to-get-running-process-list-and-traffic-statistics/.

    in RssParseHandler class

    else if (parsingImageURL) {
    if (currentItem != null) {
    currentItem.setUrl(new String(ch, start, length));

    }
    And in RssItem class

      What is the RSS feed’s URL that you are trying to parse?
      You can also send us your project to team@itcuties.com. We will try to find the solution.

      Hi there MoBr114,

      Does your RssItem class have the toString method? Does it return title attribute value?

          Hi,

          your RssItem class code should be similar to this one…

          package com.itcuties.android.reader.data;
/**
 * This code encapsulates RSS item data.
 * Our application needs title and link data.
 *
 * @author ITCuties
 */
public class RssItem {
    // item title
    private String title;
    // item link
    private String link;
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getLink() {
        return link;
    }
    public void setLink(String link) {
        this.link = link;
    }
    @Override
    public String toString() {

    Hey
    I am having a weird problem. I changed the URL from which this application parses feeds (and I used almost 2-3 different URLs), and some items in the list started to have incomplete titles. The numbers of these items is at maximum one or two, and the occurrence is also random, but this definitely is a bug. Can you guys explain what’s going on.

    Here’s the three links I used:
    http://coreyclaytonlnp.wordpress.com/feed/
    http://www.thehindu.com/news/international/?service=rss

      Hello Rajat Jain,
      Yes, there is a little bug in this code. Sometimes when RSS data is being read from the Internet, as in our example, parser calls characters method multiple times when reading tag contents. Remember that SAX is a stream parser and if the stream comes from the Internet some network delays might occur. Try using this fixed code and you are good ?

      package com.itcuties.multicategoryrssreader.util;

import java.util.ArrayList;
import java.util.List;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

import com.itcuties.multicategoryrssreader.data.RssItem;

/**
 * SAX tag handler
 * 
 * @author ITCuties
 *
 */
public class RssParseHandler extends DefaultHandler {

	private List<RssItem> rssItems;
	
	// Used to reference item while parsing
	private RssItem currentItem;
	
	// Parsing title indicator
	private boolean parsingTitle;
	// A buffer used to build current title being parsed
	private StringBuffer currentTitleSb;
	
	// Parsing link indicator
	private boolean parsingLink;
	
	public RssParseHandler() {
		rssItems = new ArrayList<RssItem>();
	}
	
	public List<RssItem> getItems() {
		return rssItems;
	}
	
	@Override
	public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
		if ("item".equals(qName)) {
			currentItem = new RssItem();
		} else if ("title".equals(qName)) {
			parsingTitle = true;
			
			currentTitleSb = new StringBuffer();
		} else if ("link".equals(qName)) {
			parsingLink = true;
		}
	}
	
	@Override
	public void endElement(String uri, String localName, String qName) throws SAXException {
		if ("item".equals(qName)) {
			rssItems.add(currentItem);
			currentItem = null;
		} else if ("title".equals(qName)) {
			
			parsingTitle = false;
			
			// Set item's title when we parse item->title tag not the channel title tag
			if (currentItem != null) {
				// Set item's title here
				currentItem.setTitle(currentTitleSb.toString());
			}
			
		} else if ("link".equals(qName)) {
			parsingLink = false;
		}
	}
	
	@Override
	public void characters(char[] ch, int start, int length) throws SAXException {
		if (parsingTitle) {
			if (currentItem != null) {
				// Here we append the title to the buffer due to network issues.
				// Sometimes this characters method is called multiple times for a tag contents.
				currentTitleSb.append(new String(ch, start, length));
			}
		} else if (parsingLink) {

      Hi Leonardo,
      Take a look on our tutorial where we show how to read, write and delete in SQLite database in Android – http://www.itcuties.com/android/sqlite-example-the-todo-application

      The best place in the code to store data in a database is after it’s has been read and parsed from the RSS channel – in the ITCutiesReaderAppActivity code. There you have a list of RSSItem objects which you can store in a database. As for reading back data to display, this activity’s code is the best place as well.

      Write a helper class which operates on a database by storing and reading back RSS data. Use it to store parsed data and read it back before the ArrayAdapter is created in the ITCutiesReaderAppActivity.

      Have a nice day,

            Hello Nikhil,
            We are experiencing no problem while running this code on the same platform you did. Check out our screencast that we did quickly http://www.youtube.com/watch?v=v3VYprccKe8. The major setting are the same as yours.
            There has to be something wrong with your emulator. Are you running other applications that use Internet connection on this device with no problem?

            Take care,

    Thanks a lot for your help ITCuties. That worked.. :)
    You are doing a very good job which is helping a lot for beginners like us.
    Can you please share the code to display an image as well in the list..

    Hi! :) First of all, a big thank you for those great tutorials and sorry for any mistake made writing in English.
    Mixing them up I was able to create my first Android App and I’ìm trying to add functions to make it better.
    I’ve got a content in my RSS feed that contains HTML content with the first image.
    So I’ve added

    private boolean parsingNotizia;

    in RssParserHandler 

    else if ("contenuto".equals(qName)) {
			parsingNotizia = true;
		}

    in startElement

    else if ("contenuto".equals(qName)) {
			parsingNotizia = false;
	}

    in endElement

    else if (parsingNotizia) {
			if (currentItem != null) 
				currentItem.setNotizia(new String(ch, start, length));
		}

    in Characters.

    In RssItem 

    private String contenuto; 
public String getNotizia() {
	return contenuto;
	}

public void setNotizia(String contenuto) {
	this.contenuto = contenuto;
    }

    I’ve also an intent that opens the list element in a new activity and I pass the “contenuto” content to this to show the full content in a new view. It shows nothing… :) but if I pass “description” it works. If I change the “print” element of the list and add the “contenuto” variable, it shows nothing too. Am I missing something?

    Hi i am working on a rssreader app which contains tags which actually has image url links as of now the rssreaderparser recognizes the tag setimage sets the url (this.url=url) which is actually the url string not the image and tostring displays the url. What i want is to dispay the image instead of links. Where do i need to make changes ? and what changes? May i mail u my application ?

      Hello,
      If you have an image URL all you need to do is something like this…

      // Get the image contents
URL url = new URL("YOUR_IMAGE_URL");
InputStream is = (InputStream)url.getContent();
Drawable drawable = Drawable.createFromStream(is,"src");
// Get your ImageView and set the drawable
image.setImageDrawable(drawable);

      Hope this works for you. Let us know.

      Take care,

          This image variable represents your variable that you probably will use to display an image. Depending on your code you will have to obtain a reference to it by calling something like this:

          ImageView image = (ImageView) findViewById(R.id.[YOUR_IMAGEVIEW_ID]);

    Hi,

    I downloded your code and tried it. But I am getting the error, “couldn’t open http://…”

    I have checked the following:-

    1. The feed is valid
    2. I have set the internet permission (as I am using your code)

    could you please help me out here.

      Hello,
      this is strange, are you able to open “http://www.itcuties.com/feed” or “http://www.itcuties.com” in your emulator’s browser?

      Cheers,

        Hi,

        I am not able to open either of the urls on the emulator. In fact I’m not able to open any website.

        So I guess the problem is with my emulator. Please help me out set up the emulator.

          Hello,
          Please check if your system firewall doesn’t block the emulator process connections. Just disable your firewall for a minute and try to run the application.
          Can you post your virtual device settings?

          Take care,

      Hello Nora,
      This is because you are running this code on an Android 4+ emulator device. If you run it on Android 2 it will work 
      This code has over an 1,5 years and a lot has changed since then, and one thing that affects this code especially – all network communication needs to be done in a separate thread using AsyncTask. Take a look here – http://www.itcuties.com/android/android-asynctask-rss-reader/.

      Have a nice day,

    I read out comments many people are facing the same error I suggest you can pin its solution on the top or after the tutorial as a note. I may help people like me :)

    Hi ITCUTIES,

    First of all, thanks for the tutorial!
    I’m having an odd problem with this RSS parser, as for some articles it will not read the entire content, but stops after 467 characters, even though it hasn’t reached the ending tag..
    This is an example of some content I’m trying to read:

    <![CDATA[Der har efterhånden været en del episoder med kidnapninger af hunde, som politiet har beslaglagt efter den kontroversielle hundelov. Den mest omtalte sag var da den ellers dødsdømte schæferhund Thor blev kidnappet af en politibetjent.Natten til søndag den 18. august 2013 blev der igen kidnappet beslaglagte hunde. Denne gang fra et dyreinternatet på Islevdalvej i København. Københavns Vestegns Politi efterforsker sagen, og leder efter 10 forsvundne hunde. Blandt hundene er en såkaldt muskelhund, en schæferhund samt en hunhund med syv blandingshvalpe.Fælles for alle hundene er, at de er beslaglagt af politiet i forbindelse med igangværende undersøgelser om skambidning eller racebestemmelse efter hundelovens regler. En racebestemmelse kan efter gældende dansk lovgivning medføre aflivning, hvis hunden vurderes til at indeholde en forbudt hunderace.Det er ikke længere tid siden end natten til fredag den 9. august, at der også blev kidnappet en anden beslaglagt hund d fra internatet. Hunden var beslaglagt i forbindelse med en sag om skambidning. De to sager har medført, at internatet ikke længere ønsker at modtage hunde fra politiet, og politiet derfor skal finde andre placeringsmuligheder imens sager om skambidning og ulovlige hunderacer undersøges.Læs mere om sagen på Ekstrabladet herThe post Beslaglagte hunde kidnappet fra internat appeared first on Dogsuniverse.dk.]]>
    Since this happens every time for this article, I suspect the reader for having an upper limit as to how many characters it is capable of storing at a given time. Everytime I run it, it stops at this exact location:
    ” Islevdalvej i København. Københavns Vestegns P” – as you can see, it was supposed to continue with:
    ” Islevdalvej i København. Københavns Vestegns Politi efterforsker sagen, og…” and so on.
    I have a hard time thinking it’s the fault of my phone, as I have an Asus Padfone2, which should be more than capable of handling more than 467 characters in memory :)

    Kind regards,
    Rasmus M. J. Jakobsen

      Hello, hello :)
      This is due the Internet connection. You need to check out our latest tutorial – http://www.itcuties.com/android/story-of-coding-itcutiesapp-for-android-parse-atom-modify-html-input-custom-listview-splash-screen-load-data-in-background/ where we have summarized our topics discussed in the past by publishing an app. Take a look at the parsing ATOM part – http://www.itcuties.com/android/story-of-coding-itcutiesapp-for-android-parse-atom-modify-html-input-custom-listview-splash-screen-load-data-in-background/#parse-rss-atom-data. ATOM has a different structure that the RSS channel you are trying to parse but the important thing here is that we are using the StringBuffer to read tag contents since the character method can run multiple times for the same tag (remember that we are parsing stream :))

        Thanks for the fast reply.
        I see that you are always mentioning the feed as ATOM. Does this mean that I won’t be able to use this reader for regular RSS?
        I have the source available as both regular RSS and ATOM – what are the diffenrences? :)

          Just a follow-up.
          I’ve taken a look at your RssPArseHandler from the 1st link you posted, and tried to implement it – thus using the StringBuffer you’ve provided. This results in some sort of Buffer Overflow exception (I can’t get a clear error through debugging), but I’ve been able to conclude that it happens during the currentTitleSb.append function.

          Here’s the code of my ParseHandler.

          public void startElement(String uri, String localName, String qName,
			Attributes attributes) throws SAXException {
		if ("item".equals(qName)) {
			m_currentRssItem = new Article();
		} else if ("title".equals(qName)) {
			m_parsingTitle = true;
		} else if ("link".equals(qName)) {
			m_parsingLink = true;
		} else if ("category".equals(qName)) {
			m_parsingCategory = true;
		} else if ("content:encoded".equals(qName)) {
			m_parsingContents = true;
		} else if ("pubDate".equals(qName)) {
			m_parsingDate = true;
		}
	}

	// The EndElement method adds the current Article to the list when a closing
	// item tag is processed. It sets appropriate indicators to false - when
	// title and link closing tags are processed
	@Override
	public void endElement(String uri, String localName, String qName)
			throws SAXException {
		if ("item".equals(qName)) {
			m_rssItems.add(m_currentRssItem);
			m_currentRssItem = null;
		} else if ("title".equals(qName)) {
			m_parsingTitle = false;
			if(m_currentRssItem != null)
				m_currentRssItem.setM_subject(m_currentTitleSb.toString());
		} else if ("link".equals(qName)) {
			m_parsingLink = false;
		} else if ("category".equals(qName)) {
			m_parsingCategory = false;
		} else if ("content:encoded".equals(qName)) {
			m_parsingContents = false;
			if(m_currentRssItem != null)
				m_currentRssItem.setM_content(m_currentTitleSb.toString());
		} else if ("pubDate".equals(qName)) {
			m_parsingDate = false;
		}
	}

	// Characters method fills current Article object with data when tags are
	// being processed
	@Override
	public void characters(char[] ch, int start, int length)
			throws SAXException {
		if (m_parsingTitle) {
			if (m_currentRssItem != null)
			{
				//m_currentRssItem.setM_subject(new String(ch, start, length));
				//m_currentTitleSb.append(new String(ch, start, length));
				m_currentTitleSb.append(ch);
			}
		} else if (m_parsingLink) {
			if (m_currentRssItem != null) {
				m_currentRssItem.setM_link(new String(ch, start, length));
			}
		} else if (m_parsingCategory) {
			if (m_currentRssItem != null) {
				if(!new String(ch, start, length).equals("Artikler")){
					m_currentRssItem.setM_category(new String(ch, start, length));
				}
			}
		} else if (m_parsingContents) {
			if (m_currentRssItem != null) {
				String content = new String(ch, start, length);
//				m_currentRssItem.setM_content(content);
				//m_currentContentSb.append(new String(ch, start, length));
				m_currentContentSb.append(ch);
			}
		} else if (m_parsingDate) {
			if (m_currentRssItem != null) {
				m_currentRssItem.setM_date(new String(ch, start, length));
			}
		}
	}

          As you can see, I’ve tried using both the append(StringBuffer) and append(char[]) – neither of them work and both produce an instant crash when trying to load the articles. At this point, I’m clueless as to why I would receive a buffer overflow exception, as the articles really aren’t that long (as you can see from the OP) and any suggestions would be of great help :)

      Hello, these strange characters are the RssItem class default representation of an object. You are missing the toString method in your RssItem class.
      Here is the code:

      public String toString() {
     return title;
}

    Hello,

    By using your code I get a problem with the titles of some articles. When the title contains a special character ( ’ in the html source code of the rss feed link) the title is cut, only the part of the title after this character is displayed in the application.

    For example : There is one article named Let’s go! in the feed, but in the html source code of the feed it is Let’s go! . In the application only s go! is displayed as the title of the article.

    Where in the app could I modify the ’ symbol or deal with it ?

    Thank you in advance.

      Here is the right piece of code that solved my problem :

      In characters method of RssParseHandler.java I changed this :

      if (parsingTitle){
    if (currentItem != null) {
        currentItem.setTitle(new String(ch, start, length));
    }

      to

      if (parsingTitle){
    if (currentItem != null) {
        if (currentItem.getTitle() == null){
            currentItem.setTitle(new String(ch, start, length))
        }else {

    Hello,

    Thanks for posting and it helps a lot to me. One thing that i really want to add to this code is adding a Image [like thumbnail] in RSS which will appear on left side of TEXT [Title, description...]. But problem is, hard to get Image URL from XML file.

    My app getting feeds from several XML and image url of some feed page is included in node named “content:encoded” and some page includes this url in description node. And also those node includes not only IMAGE URL, also several contents like below,

    [XML was here :)]

    Here my question is,

    Hi guys!

    There seems to be a problem with the getItems() method in the RssReader class.
    This method must return a result of type List
    But the thing is that if returned handler.getItems(), you get the following message: The method getItems() is undefined for the type RssParseHandler.

    Hello itcuties,

    Thank you so much for this wonderful tutorial.
    I have a short question: I have some feeds that are not opening and I’m guessing that this issue is caused by the fact that the rss feed is not available on the mobile version of the site.
    Please check: http://www.antena3.ro/rss
    Opening this URL from the browser it will generate a “Not Found” error because it will redirect me to m.antena3.ro/rss which is not available.
    It is my guess that your class will doing the same and the feed will not be available in the app
    Is there a way to fix this?

    Many thanks,
    Cosmin

        Yeah, the problem is that they don’t have a mobile version of the feed and when trying to access http://www.antena3.ro/rss it redirected me to m.antena3.ro/rss which was invalid.
        I had to save the .xml locally using a ‘desktop’ User-Agent and parsing it from there afterwards
        Thanks again

    Alternatively, you can use a third party RSS library such as this one:
    https://github.com/Pkmmte/PkRSS

    It handles all RSS code via a fluent API and is very customizable.

    // Load a URL
PkRSS.with(this).load(url).async();

// Get the feed
List articleList = PkRSS.with(this).get(url);

    There are also callbacks, synchronous calls, a favorite database, marked as read, pagination support, searching, custom parsers/downloaders, and more.

    Hello There,

    I am a bit new to android development and I found this tutorial to be awesome!. I am having a problem trying to add a refresh button that will actually refresh the page and ‘re load’ the rss page.

    The only thing I have been able to do is get the refresh button to show up on the correct page and when its pressed it displays refresh clicked, as is shown in the code below.

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);

    return super.onCreateOptionsMenu(menu);
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
    case R.id.action_refresh:
    Toast.makeText(this, “Refresh clicked”, Toast.LENGTH_SHORT).show();
    return true;
    default:
    return super.onOptionsItemSelected(item);
    }
    }

    If possible would you please be able to help with implementing a refresh button.

    Thank you so much for all your help and again, your tutorials are awesome :)

    The tutorial uses SAX parser and includes a complete Android project that accesses an RSS feed and then displays the feed in a list view.

    Hi, first thanks for the tutorial.

    I have an issue if you don’t mind answering a beginner’s question. I want to move onItemClick from ListListener.java to RssChannelActivity, so that I could add other clicking options. I am able to implement clicking and other options, but I could not get the link to open in a browser. Here’s the sample code:

    inside onPostExecute(List result)

      itcItems.setOnItemClickListener(itemClickListener);

    outside onPostExecute:

    OnItemClickListener itemClickListener = new OnItemClickListener() {
	@Override
    public void onItemClick(AdapterView parent, View view, int pos, long id) {


                        Intent i = new Intent(Intent.ACTION_VIEW);
 			i.setData(Uri.parse(listItems.get(pos).getLink()));
  			startActivity(i);

	}

    Error

    08-08 08:58:42.780: E/AndroidRuntime(26909): Caused by: java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.example.RSS/com.example.RSSReader.RssChannelActivity}: java.lang.InstantiationException: can’t instantiate class com.example.RSSReader.RssChannelActivity; no empty constructor

    What does this mean? How is possible that I can implement item click, popping up a toast, but not open the link?

    I am using fragments instead of activity for the RSSFeed for my application. I am facing problem in the postExecute method as i have declared the local variable of Fragment type.
