Deserializing JSON in Java objects, as you did in Listing 25.12, is a common task in app development regardless of the platform. Lots of smart people have created libraries to simplify the process of converting JSON text to Java objects and back again.

One such library is Gson (github.com/​google/​gson). Gson maps JSON data to Java objects for you automatically. This means you do not need to write any parsing code. For this reason, Gson is currently our favorite JSON parsing library.

For this challenge, simplify your JSON parsing code in FlickrFetchr by incorporating the Gson library into your app.
