I am stuck on this one

Challenge task 2 of 2

CodeChallenge.java 
JSONArray jsonShows = jsonData.getJSONArray("books");
for (int i = 0; i < jsonShows.length(); i++) {
    JSONObject movie = jsonShows.getJSONObject(i);
    String title = movie.getString("title");
    Log.i("CodeChallenge", title);
}



// JSONObject 'jsonData' was loaded from data.json
data.json 
{
    "name":"Netflix Playlist",
    "shows":[
        {
            "title":"Doctor Who",
            "season":8,
            "episode":3
        },
        {
            "title":"Arrow",
            "season":1,
            "episode":10
        },
        {
            "title":"Portlandia",
            "season":4,
            "episode":5
        }
    ]
}

All your Java is right, just change this:

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

to this:

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

Because you are looking at the list of shows:

{
    "name":"Netflix Playlist",
    "shows":[
        {
            "title":"Doctor Who",
            "season":8,
            "episode":3
        },
