"The data in the file data.json has been loaded into a JSONObject named jsonData." The error that you are getting is because of the "haye" that you are adding. there is no need for another JSONObject because the line i quoted above says that has already been done. get rid of your "haye" first line and just use the JOSObject jsonData, for example:

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