data parsing final challenge task 3 of 3

i need the format : book title, a comma, a space, and the number of pages.

example : 'book title 1, 300'.

my code output

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

no compiler errors just "bummer! make sure you write each book to the log exactly as specified in the instructions.

Any help much appreciated have worked many different ways of doing it but with out being able to see how it is coming out can't tell what i'm missing.

Your output must look similar to the following in the LogCat Console right?

CodeChallenge title, pages

It's because you are passing String literals instead of variables.

Try removing the quotation marks around the variables... e,g,

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

Hope this helps

I didn't realize it sorry for the trick question I didn't purposely do that but the error was a couple lines above that line. I was saving the number as a string.

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

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 = jsonData.getString("title");

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

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

I am still getting the same error :(

Thanks in advance
