One thing to note, maybe you don’t know about it, is that OkHttp interceptors work with IOException. So if you decide to implement some kind of a retry mechanism – to refresh a token when you get a forbidden response code, to retry a request, or something else, keep in mind that if you throw anything different than IOException or a subclass of it, like InvalidStateException, your app will crash and the exception will not even reach the try-catch block of your code.
