Android Build a Weather App (2015) Working with JSON Using JSONObject

Using JSONObject task code

My code won't work and have no idea why. It says its something to do with using a string in the "new JSONObject(jsonData)" line.

I'm aware that jsonData is a string but in the actual code for the project it is aswell and the code has no problems. Can anyone help? Or does anyone have the correct code for this task?

JSONChallenge.java 
JSONObject forecast = new JSONObject(jsonData);
String name = forecast.getString("name");
String publisher = forecast.getString("publisher");
String language = forecast.getString("language");
data.json 
{
    "name":"Treehouse Book Series",
    "publisher":"Wiley",
    "language":"English",
    "books":[
        {
            "title":"HTML5 Foundations",
            "author":"Matt West",
            "pages":384
        },
        {
            "title":"CSS3 Foundations",
            "author":"Ian Lunn",
            "pages":352
        }
    ]
}

Hi Thomas,

1) A JSONObject has already been created for us (the first sentence of the challenge states 'The data in the file data.json has been loaded into a JSONObject named jsonData'), so we can remove that 'JSONObject forecast = new JSONObject(jsonData);' statement.

2) Since the name of the JSONObject that was already made for us is jsonData, that is the object we'll reference, so that we can get values for our strings from what's stored in that object.

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

Hope this helps!
