Hello, guys welcome to WordPress to Android App Tutorial. In past few years WordPress has grown so much. It is the most popular blogging platform as more than 60 million websites are running on it.

WP REST API is one of the best features added to WordPress. It allows developers to create apps that can easily integrate with WordPress platform. Using this API we can easily retrieve our WordPress site’s data like posts, media, users, etc in JSON format by just sending HTTP request.

So in this tutorial I will teach you to make a very basic Android app for WordPress blog or website using WP REST API.

Note: This tutorial is about creating a very basic Android APP using WP REST API. If you are looking for a complete app with all the standard features like, PUSH NOTIFICATION, BOOKMARKS, SOCIAL SHARING etc. Then you can buy it from us. To get the Android App for your WordPress Blog CLICK HERE.

REST API – Filter Fields

Just go the links that I have given above to download and then install these plugins on your blog.

Fetching All Post of Your Website

  • You can fetch information about all the post on your blog by following URL.

http://your-blog-url/wp-json/wp/v2/posts

  • For a real example you can see the URL with my blog. Just go to the following link

http://www.thejavaprogrammer.com/wp-json/wp/v2/posts

  • You will see the following JSON Data.

Fetching Specified Number of Post

  • For fetching specified number of posts you can use post-per-page filter. The below URL will fetch only 3 posts.

http://your-blog-url/wp-json/wp/v2/posts?filter[posts_per_page]=3

Fetching Particular Post

  • You can fetch any particular post by its id.

http://your-blog-url/wp-json/wp/v2/posts/67

  • Here 67 is the id of the post.

Filtering Fields

  • As you have seen in above JSON data that there are several fields that we don’t require. So with the help of REST API – Filter Fields plugin you can filter few fields. For example you want to fetch only post’s id and title then it can be done by using following URL.

http://your-blog-url/wp-json/wp/v2/posts?fields=id,title

  • You can also fetch other fields along with id and title by just adding them in the URL. Like if you want to fetch id, title and content then it can be done using following URL.

http://your-blog-url/wp-json/wp/v2/posts?fields=id,title,content

  • Just make sure you use valid field name.

I hope now you got basic idea of using WP REST API. You can learn more about it by reading API documentation at below link.

  • Now come inside MainActivity.java and write the following code.
