Looks interesting... What's the status of these in RxJava? Did they prove to be useful and will remain there?

I think some Android developers like this one. Most of their cases only need this special Observable, e.g., request a request from network and render it in UI. In addition, see ReactiveX/RxJava#1594 (comment) for the discussion in RxJava.

@samuelgruetter last I checked in RxJava, rx.Single is still @Beta. That being said, I think it has had a fair bit of traction - my team at work uses it in the code base (so hopefully it doesn't go away!). One thing that takes a bit getting used to is that Singles can only emit a value or error, there is no "empty".

Due to project EOL status, Single will not be ported from RxJava
