This topic has been hashed quite a bit - but there doesn't seem
to be a clear answer - at least not one that i could find.

Background - I'm developing an app and I think some processing can
be done in the background - e.g. database and image processing
(create bitmaps, rotate etc - i can do that in a background right?).

So I'd like an efficient way of calling the background when to start
a specific job and then have the background service notify the caller
with a result when done.

Option 1 - create a service - that waits and returns status. haven't
figured out a way of doing the latter.

Option 2 - I suppose I could start a new activity with no UI and then call
startIntentForResult(). i.e. an Acitivy for each background job.


Suggestions?
