Hi, I built a small library for Android, it helps you to add custom annotations on retrofit calls and retrieve them later via interceptor Check it out and give me your feedback https://t.co/FF72E0GR1s

I think there is an easier way. but i have not played with it yet. Retrofit adds an implicit

Tag

called

Invocation

that has a reference to the

Method

at which point you can query for custom annotations via the normal reflection api's. All of which can be done in an interceptor without the need for a custom call adapter factory.

Been meaning to POC this out. let me see what I can throw together today and i'll post back here

single base class that is pretty damn simple. then the test file has an example use-case

something wrong in the way I am mutating the request but proves that it at least picked up the annotation and tried to muck with it

very cool that's a better and simpler way to do it 👏

i wasn't aware that retrofit add

Invocation

Tag to all its requests

I knew about tag. but Jesse wilson is who got me thinking about how to do some of this easier. https://twitter.com/jessewilson/status/1231569857986035712

only other note i'd add about that, is the call to

Method.getAnnotation(Class<T>)

might be expensive and worth caching in a map. ie

val annotationCache: MutableMap<Method, T>

where T is the annotation.

yes totally agree caching annotation worth it
