Gson Android Kotlin Tutorial – Convert Interfaces to & from JSON

Gson is an open-source JSON library which aims to be simple and quick to use while providing a bunch of options to accommodate even some complex use cases.

In this tutorial you’re going to learn how to serialize and parse interfaces to JSON strings. An interface cannot be instantiated so we need to somehow remember the the class which implements our interface and instantiate this class directly. GSON lets us do it in an elegant and simple way.

This post contains all the code that’s been written in this YouTube video.
