//JSONObject 'jsonData' was loaded from data.jsonJSONArray jsonBooks = //jsonData.getJSONArray("books");

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

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

String title = jsonData.getString("title");

int pages = jsonData.getInt("pages");

I had an issue with working through this example for a time as well. This looks exactly like my answer except for: Instead of passing it the jsonData.get line I used the JSONObject that we both createad inside the for loop

So... String title = jsonBook.getString("title");

Instead of: int pages = jsonData.getInt("pages");

I passed it as a string variable. So I changed you're line into:

String pages = jsonBook.getString("pages"); and it worked for me.

However, now seeing that the data.json page does not use double quotes your answer may be more correct.

Good find! Yes, you are calling getString() and getInt() on jsonData when you should be calling those on jsonBook.
