java – A queue of background tasks in rxjava

Questions:

Is it possible to implement a queue of background tasks using rxjava?
I need possibility to add task at any time and only one tasks executed simultaneously. I have tried PublishSubject, but when i’m pushing execution to the new thread observeOn(Schedulers.newThread()) it starts more than one task at time.

UPDATE:
Is it possible to implement something like producer-consumer pattern using rxjava?

How to&Answers:

Just use a scheduler based on a single thread executor:

Scheduler scheduler = Schedulers.from(Executors.newSingleThreadExecutor());
observable.observeOn(scheduler). ...
