Late, but I thought this might be useful for anyone using RxJava in their application.

RxJava comes with an operator called .timer() which will create an Observable which will fire onNext() only once after a given duration of time and then call onComplete(). This is very useful and avoids having to create a Handler or Runnable.

More information on this operator can be found in the ReactiveX Documentation

// Wait afterDelay milliseconds before triggering call
Subscription subscription = Observable
        .timer(5000, TimeUnit.MILLISECONDS) // 5000ms = 5s
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Action1() {
            @Override
            public void call(Long aLong) {
                // Remove your AlertDialog here
            }
        });

You can cancel behavior triggered by the timer by unsubscribing from the observable on a button click. So if the user manually closes the alert, call subscription.unsubscribe() and it has the effect of canceling the timer.
