Answer 2

You will have a class Category with attribute mcategory_id. Then you will have a class effect_list which will contain a list of items that contains "effects_id". So basically you will need 4 classes.

Class Category with mcategory_id.

Class Effects with effects_id.

Class Effect_list (in your json is a object not a list) which will contain a list of Effects ("14" name in your json)

And a response class for your retrofit: Retrofit class will contain List of Category("categories"called in your json) and a object of Effect_list(called "effect_list" in your json).

Use annotation @SerializedName so that you can map easily the json into your objects.
