Will they be invoked one after the other, in the order they were raised.
As Mark already said, yes, it's sequential.
If you look at the implementation:
https://github.com/android/platform_frameworks_base/blob/master/core/java/android/app/IntentService.java
... it's really simple, and uses HandlerThread, which is a small helper
class that creates a thread which sits in a loop processing messages one
by one.
Is there any chance that 'onHandleIntent' will be called in parallel,
to handle more than one intent simultaneously.
If that's what you want, you could very easily implement this:
- Either by using ThreadPoolExecutor:
http://developer.android.com/reference/java/util/concurrent/ThreadPoolExecutor.html
- Or by using AsyncTask.
Note that starting with Android 4.0 you'd need to use
task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR) if parallel
execution is desired.
- Or in some other way....
The important thing (besides posting work to another thread or a pool of
threads) is to manage the service's lifetime by calling
stopSelf(startId), where startId is the value from the service's
onStrartCommand that corresponds to the Intent you just finished processing.
