RSS Parser

Download License API

RSS Parser is an Android library to parse any RSS feed. With RSS Parser, you can fetch plenty of useful information from any RSS channel, be it a blog, magazine, or even a podcast feed.

As of April 2020, it's been downloaded more than 30,000 times from 125 different countries (among them, North Korea, Madagascar and even Panama 🌴).

⚠️ Important Notice

Versions 1.4 and 1.4.1 have been deleted due to a critical dependency error. Please forgive me and update to the latest version available.

Table of Contents

Available data

The RSS channel resulting object provides you with the following data:

  • Title
  • Description
  • Link
  • Articles
  • Image (Title, Url and Link)
  • Last build data
  • Update period

Articles, on the other hand, support the following attributes:

  • Title
  • Author
  • Description
  • Content
  • Main Image
  • Link
  • Publication Date
  • Categories
  • Audio
  • Source (name and link)



The library provides a caching layer to avoid wasting data with very long feeds. All you need to do is provide an expiration date. For more details, give a look to the Usage section

⚠️ For the time being caching is only supported if you are using Kotlin.

RSS Parsing from string

The library provides a way of simply parsing raw data from a string.


The library is provided by jCenter, so you can easily add its dependency and be good to go.

dependencies {
  implementation ''



First of all, you have to create a

object with the Parser Builder. In the builder you can provided some custom and optional fields:
  • A custom
    ; if not provided, the library will create one for you.
  • A custom Charset; if not provided, the default one is
  • The Android Context, mandatory to make the caching layer work.
  • The cache expiration date in milliseconds, mandatory to make the caching layer work.

If you don't provide the Android Context and the cache expiration date, the library will continue working but without the caching feature.

val parser = Parser.Builder()
                .cacheExpirationMillis(24L * 60L * 60L * 100L) // one day

The library uses the Kotlin Coroutines to retrieve, parse and cache the feed. So to start the process, you need to launch the coroutine.

//url of RSS feed
private val url = ""

viewModelScope.launch { try { val channel = parser.getChannel(url) // Do something with your data } catch (e: Exception) { e.printStackTrace() // Handle the exception } }

For flushing the cache:


For simply parsing raw data: - A

which returns the channel.
// parser without any network or caching configuration
val parser = Parser.Builder().build()

viewModelScope.launch { try { val channel = parser.parse(raw) // Do something with your data } catch (e: Exception) { e.printStackTrace() // Handle the exception } }

Starting from the version 2.x, the library has been completely rewritten using Kotlin and the coroutines. However, the compatibility with Java has been preserved and the same code of the versions 1.x can still be used.

⚠️ For the time being, the caching is not supported if you are using Java.

If you are still using Java, this is the interface to use the library:


Parser parser = new Parser.Builder() .charset(Charset.forName("ISO-8859-7")) // .cacheExpirationMillis() and .context() not called because on Java side, caching is NOT supported .build();

parser.onFinish(new OnTaskCompleted() {

//what to do when the parsing is done
public void onTaskCompleted(Channel channel) {
    // Use the channel info

//what to do in case of error
public void onError(Exception e) {
    // Handle the exception

}); parser.execute(urlString);

For parsing raw data there is a java compatible function which calls the listeners

once done.

Parser.parser(rawRssFeed, OnTaskCompleted)

The full Java sample is available here

Version 1.4.4 and below

For older versions of the library, the interface is marginally different:


//url of RSS feed String urlString = ""; Parser parser = new Parser(); parser.onFinish(new Parser.OnTaskCompleted() {

public void onTaskCompleted(Channel channel) {
  //what to do when the parsing is done

public void onError() {
  //what to do in case of error

}); parser.execute(urlString);

Sample app

I wrote a simple app that shows articles from Android Authority. If in the article's content there isn't an image, a placeholder will be loaded.

The sample is written both in Kotlin and Java. You can browse the Kotlin code here and the Java code here You can also download the apk file to try it!

Please use the issues tracker only to report issues. If you have any kind of question you can ask it on the blog post that I wrote
