The problem you are having is that you are using the string title not the book title. You need to change the last line of your for loop where it creates the string in the Log to the code below:

(basically reference the book title by creating a new string variable and assigning it the book title and use that)

String name = jsonData.getString("name"); 
String publisher = jsonData.getString("publisher"); 
String language = jsonData.getString("language");

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

for(int i = 0; i < jsonBooks.length(); i++){
  JSONObject jsonBook = jsonBooks.getJSONObject(i);
  int pages = jsonBook.getInt("pages");
  String title = jsonBook.getString("title");
  Log.i("CodeChallenge", title + ", " + pages); }

Hope this helps Daniel
