In this episode, we talk to our good friend and immutability champ Ryan Harter. We start off talking about the benefits and disadvantages of immutability, then we dive into Value types and the subtle difference with Value types. Finally we close out by talking about AutoValue and how you can extend it using the super nifty auto-value extension system for functionality like Parcelability, Json parsing etc.
