Stuck on the code challenge; Parsing Data Returned in JSON Format objective 3

i am getting the message; Bummer! Your loop should run twice and call 'getJSONObject()' each time through. I am doing my best but don't get now I am lost, guess need to practice more. 

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);
Log.i("CodeChallenge", jsonBook.getString("title") + ", " + jsonBook.getInt("pages"));
}

Just did this one a little while ago. If I remember correctly, in JSONArray jsonBooks = jsonData.getJSONArray("Books"); I believe the name of the array is "books" not "Books", is it not?

Hey,

I was stuck on this part too.

I took your code, formatted it and changed "Books" to "books" and then it worked!

Hope this helps :)

Hi Ray,

Unfortunately it's not the Books but thank you for your effort.

Wow. That worked for me John. Thanks! I've been on this one for about 30 minutes and couldn't figure out why.

Changing:

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

to:

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

worked. Odd that it accepts the first one for part 2, but not in part 3.
