问题
From what I understand, an IntentService can only handle one Intent at a time as it shares a worker thread to do all of its work. But if I have multiple IntentServices in my app, can they run in parallel, or do they all share the single worker thread as well?

If you mean that you have multiple subclasses of IntentService, they should be able to run in parallel.
