how to fetch tags from wordpress posts JSON results in android Java

Question

I am trying to make an android app that fetch posts from my wordpress blog that displays the information in a list. I am able to get the results like title, description,etc but i am not able to get nested object "tags" from the JSON result. So, can you explain me how i can get the tag names from the JSON result from this JSON Response.

I am trying to use the following code :

JSONObject root = new JSONObject(postJSON);
        JSONArray postsArray = root.getJSONArray("posts");


        for (int i = 0; i < postsArray.length(); i++) {
            // Get a single post at position i within the list of earthquakes
            JSONObject currentPost = postsArray.getJSONObject(i);

            String title = currentPost.getString("title");
            Log.e(LOG_TAG, "title is " + title);

            JSONObject tags = currentPost.getJSONArray("tags").getJSONObject(0);
            String tag = tags.getString("name");
            Log.e(LOG_TAG, "tag is " + tag);

            Post post = new Post(title,"123", tag);
            posts.add(post);
        }

But the logcat is showing that the value can't be converted to JSONArray.

The issue is that tags is actually another JSON object not a JSON array. You need to do the following:

JSONObject tags = currentPost.getJSONObject("tags").getJSONObject(0);
String tag = tags.getString("name");
Log.e(LOG_TAG, "tag is " + tag);

Just remember JSON arrays are always denoted by [] and objects by {}.

Hope this helps.

you are right, BUT now the problem is that you can't use int as an input for JSONObject.
