I am attempt to observe on java.lang.Void but my 204 responses are still coming back with null pointer exceptions:

How do I handle 204s..?

Try using Unit instead of Void. You can't have null items in your stream in RxJava2, so you can't get emissions from Observable<Void>.

[Regan Russell]

ah no, I think I originally tried observing on Unit and I just tried again but that also comes back with the same null pointer exception. I may have to shelve it and move onto other code and come back to it...

@Regan Russell, you can use Observable<Response<Void>> instead Observable<Void>

[Reyst]

and check answer code from response like this protected boolean convertResponseCodeToBoolean(Response<?> response) {
return (response.code() >= 200 && response.code() <= 299);
}

cool, hang on a a sec I have to stash some stuff and I will check it out.

[Regan Russell]

Cool, I see a response 204 in the raw response now.. Awsome, thanks.

You're welcome

Completable?

@Regan Russell +1 for Completable
But if you still need Unit you can use this approach:
