How to execute RoboSpice requests synchronously?

Question

How to execure RoboSpice requests synchronously? Is it possible? I would like to use RoboSpice in IntentService.

Edit:

From time to time comes the need to execute something synchronously e.g. in service. In my recent project I have to queue some different types of requests and I wanted to use IntentService with RoboSpice. In my case when I'm executing different requests I need to wait for results from request1 then pass data from it to request2 and execute it.

I want to have some kind of batch request queue. Lets say we have two types of request: request1 and request2. request2 needs data fetched by request1:

1. execute request1
2. wait
3. get data fetched by request1 and pass to request2
4. execute request2
5. wait
6. goto 1.

I wanted to use IntentService (queue) but it dies after starting requests because of async.

In my opinion using listeners or CountDownLatch isn't the best way.

As proposed by Riccardo Ciovatti on the RoboSpice mailing list, a direct answer to your question is :

final CountDownLatch latch = new CountDownLatch(1);

final YourRequest request = new YourRequest();
spiceManager.execute(request, new RequestListener<YourResponse>() {

    @Override
    public void onRequestFailure(SpiceException spiceException) {
        latch.countDown();
    }

    @Override
    public void onRequestSuccess(YourResponse response) {
        latch.countDown();
    }
});

latch.await();

But this isn't a good idiom to use unless it's being executed on a background thread. Asynchronous processing is an essential feature of RoboSpice; it keeps the UI thread free.
