RX Java – rxjava returns a single, which is completed after execution

I'm trying to do the following: return some data as a single, and then execute it after completion Due to single Andthen(), the following code cannot be compiled Operations need to be performed in this order

val single = Single.create<String> { it.onSuccess("result") }
val completable = Completable.create { println("executing cleanup") }
val together = single.andThen(completable)

together.subscribe(
        { println(it) },{ println(it) }

)

Solution

Using flatmap:

single.flatMap(v -> completable.andThen(Single.just(v)))
