Custom converter for Retrofit 2

by

I was looking for a simple example about how to implement a custom converter for Retrofit 2. Unfortunately found none.

I found this example but, at least for me, it’s too complicated for my purpose.

Happilly, I found a solution.

This solution is to use GSON deserializers.

We don’t need to create a custom converter, we just have to customize the GSON converter.

Here is a great tutorial. And here is the code I used to parse the JSON described in my question:

  • Login Deserializer: Defines how to parse the JSON as an object of our target class (using conditionals and whatever we need).

  • Custom GSON converter: Builds a GSON converter that uses our custom deserializer.
