I'd like to make a hashmap, which will store String, that should store property name, and double, which should store property value "object":{ "firstName" = 1.1111 "SecondName" = 2.2222 etc... } So it should looks like this: key = "first name" and the value = 1.1111 Since I've got it via retrofit, I've prepared a model class which already has declared all of the variables needed to get proper...
