How to get and display Wordpress featured media and author image?

Question

I am creating an android app that displays WordPress posts. At the moment, the app is displaying the title and subtitle (3 lines of text) but, it doesn't show the featured image. I also would love to get the author image, too (if possible) but I am more worry about the featured image. I tried to google it but I might be asking the wrong question. I also tried to get the image path but it didn't work at all. According to JSON the featured image contains an id, and this id can be used to get the path. But, no luck.

EDIT: I tried to add this code inside the RecycleViewAdapter.class but still no luck

Glide.with(mContext).load(response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl())
                    .into(imageView);

Edit - So, someone sent me a few details. But I still don't get it. The last time that I tried to create an android app was in 2014-2015. Here are the details:

Yes, you can fetch everything from your WordPress website. WordPress store blog post image on another table. so follow this step

1) get blog post using REST APi..it will be a JSON array.

2) check each json object, each have this JSON object- Links --> WpFeaturedmedia--->object(0)-->Href

3) this Href is index of image for the blog post.

4) pass this href to adapter..

5) inside adapter class again use another retrofit call for this href url

6) the response of this retrofit will have all images(multiple sizes) of blog post. response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl()

7) pass it to glide method (inside adpater class only) Glide.with(mContext) .load( response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl()) .into(imageView);

Finally, response POJO in adapter is not the response POJO that you use on activity. Create another POJO for image url.

Answer 1

Ok so after doing some research, i have found that you just have to concate _embed at the end of your url and you will be able to get featured image as well as author bio with image.

Here is the demo url

https://www.myfitbytes.com/wp-json/wp/v2/posts?_embed 

And from there you can get author data inside _embed object

And for featured image it will look like
