>The problem I'm having is only the fields that are present in the Json string (id and artist ) are getting deserialized, what I want is for the other properties to be set to null which I will populate later. Any ideas ?

Not an answer to your question but if you are using this to retrieve data from a server you could take a look at Retrofit : http://square.github.io/retrofit/
Once set up it's simple to make async calls to the server and get back results already converted to Java objects (you can specify GSon as the converter)
