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

Question

I\'m trying to develop an Android app for browsing a Wordpress-powered blog I own. I\'m trying to figure out how to retrieve posts and other information from the blog to display

Answer 1

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 .

Answer 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 : https://github.com/canbican/wordpress-java/blob/bb4b60a008ee6d280aedd9174df4a657bff683ac/src/net/bican/wordpress/example/Main.java

Also, if you're using Gradle, check this dependencies problem you may face : https://github.com/canbican/wordpress-java/issues/54

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).
