You have the first part almost there. But :

1) You are getting the wrong item name. The array is called "shows", not "books"

2) You need to put in the for loop now. ( They show you how in the previous video )

// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("shows");

for(int i=0;i<jsonShows.length();i++){
 Log.i("CodeChallenge", jsonShows.getJSONObject(i).getString("title")); 
}
