When should one use RxJava Observable and when simple Callback on Android?

Question

I\'m working on networking for my app. So I decided to try out Square\'s Retrofit. I see that they support simple Callback

@GET("/user/{id}/         


        

Answer 1

I personally prefer to use Rx to get api responses in cases that I have to do filter, map or something like that on the data Or in cases that I have to do another api calls based on previous calls responses
