Getting Data from website coding challenge

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);
String title = jsonBook.getString("title");
String pages = jsonBook.getString("pages");
Log.i("CodeChallenge",  i + title + ", " + pages);

}

So here is my problem: inally, write a 'for' loop that loops through 'jsonBooks'. In each step of the loop, use 'getJSONObject(int index)' to get a JSONObject from the array. Then use the 'Log.i()' method (with "CodeChallenge" as the tag) to write the book title, a comma, a space, and the number of pages. Ex. output: 'Book title 1, 300'.

Here is my error: Bummer! Make sure you write each book to the log exactly as specified in the instructions.

Any help on this would be much appreciated. I've been stuck on this for like two days

I got stuck there too with the same problem...

String pages = jsonBook.getString("pages");

This is the problematic line: in the JSON "pages" is an int, not a string. You have to use .getInt() instead.
