I believe that you are expecting the IntentServices to act like threads. You will not have multiple instances of an IntentService run at the same time. From the documentation at http://developer.android.com/reference/android/app/IntentService.html:
All requests are handled on a single worker thread -- they may take as long as necessary (and will not block the application's main loop), but only one request will be processed at a time. I admit, the IntentService's documentation isn't very clear. But in any case, if you have multiple starts of an IntentService, they will happen one after the other, and not at the same time. -Matt On Nov 4, 1:54 pm, Bret Foreman <[email protected]> wrote: > I'm trying an experiment where an Activity makes a number of > consecutive calls to an IntentService.
