How to retrieve posts from a WordPress Blog in an Android App?

1. Yes, it can be done.

   One way is to use the xml-rpc api. WordPress blogs have an xml-rpc api(which you need to enable on the WordPress blog under “Settings – Writing”). You will also need to create a user on the blog, which you give at least read access, and for which you include the credentials in your app.
   From then on, you can do xml-rpc calls to your WordPress blog(s).

   If using this xml-rpc api is an option, take a look at this Java lib: http://code.google.com/p/wordpress-java/

   You can get the blogposts using this lib like this:

   String username = args[0];
   String password = args[1];
   String xmlRpcUrl = args[2];
   Wordpress wp = new WordPress(username, password, xmlRpcUrl);
   List<Page> recentPosts = wp.getRecentPosts(10);
   

   Also, the official WordPress Android app is open source. Instructions to get it are at: http://android.wordpress.org/development/
   You could use this source code as a starting point and adapt it to your needs.

   Note that you can only use the xml-rpc api when you have a user with read access. If you do not have the credentials of a user with read access, you can’t get the posts using the xml-rpc api.
   Fetching the rss feed and parsing the rss feed with some java lib would probably be your best bet then(check http://www.vogella.com/articles/RSSFeed/article.html on how to read an rss feed using Java).

2. As Integrating Stuff said, the ‘net.bican:jwordpress:0.6.4’ is what you need.
   Still, the example he gave is now deprecated. There is no more getRecentPosts(int) but getPosts(FilterPost).

   So now the correct code is :

   String username = args[0];
   String password = args[1];
   String xmlRpcUrl = args[2];
   Wordpress wp = new WordPress(username, password, xmlRpcUrl);
   FilterPost filter = new FilterPost() ;
   filter.setNumber(10);
   List<Post> recentPosts = wp.getPosts(filter);
   

   to know more check the example :

   Also, if you’re using Gradle, check this dependencies problem you may face :

3. There is an alternative way also , and its working good,

   you can install json plugin in your word press and you can retrieve all the post by requesting the url … and parsing the response json in your android views will be working .
