Sorry, I was wrongin my first post.

The correct code is:

JSONArray jsonShows = jsonData.getJSONArray("shows");

This drills down into the shows data array.

Next you call the getJSONObject() method against each member of that data array.

From there you drill in further to pull out each title, as follows:

for (int i = 0; i < jsonShows.length(); i++){
    JSONObject obj = jsonShows.getJSONObject(i);

    Log.i("CodeChallenge", obj.getString("title"));
}

Hope that helps!!

Steve.

Here's the hard bit ... have a go and see if that works then crack on with the for loop.

Let me know if you need a walk through this code. 

JSONArray jsonShows = jsonData.getJSONArray("titles");
