Help with a code challenge? Parsing data returned in JSON format.

I have worked on this code challenge for awhile and I have been fixing all the errors I was making, but I'm not sure how to fix this one.

The error states: Bummer! Your loop should run twice and call 'getJSONObject()' each time through.

I'm not sure if I'm supposed to be changing the jsonBooks.length and if so what do I change it to?

`String name= jsonData.getString("name"); String publisher= jsonData.getString("publisher"); String language= jsonData.getString("language"); JSONArray jsonBooks= jsonData.getJSONArray("jsonBooks");

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

Hi Ginger,

It looks like you have two minor issues.

First, this line:

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

Should be:

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

And this:

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

Should have a space after the comma, making it:

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