Observable which does not pass anything in onNext()

Question

I would need an Observable, for example to provide a system clock, which does not need to pass anything in onNext(). I couldn\'t find a signature that would allow me to do that.

Answer 1

One of the light solutions is to use Observable

And then onNext(Boolean.TRUE) which you then just ignore.

But probably you shouldn't use Observable in that case.
Consider using Completable instead
