57,712 PointsHi there,
You need to access the key/value pairs in the dictionary by getting to it with the appropriate accessor. In this case, each value you are brining back is a String, so the getString()
method will work fine. You use that method with the jsonData
variable that has been set up for you - dot notation will work for this.
String name = jsonData.getString("name");
String publisher = jsonData.getString("publisher");
String language = jsonData.getString("language");
I hope that makes sense.
Steve.
