A few quick questions I tend to ask people using services:
1) Do you really need a service? If all you want to do is some
background processing that is transient in nature, a regular thread is
OK. It will be killed eventually when your app is no longer on-screen
but maybe you can deal with that.

How about doing option 1, but having the caller include a PendingIntent for
where the result should be sent. This way the caller doesn't even need to
stick around while your service is running -- it can give you a
PendingIntent that launches a receiver when you send it back.

Thank you for your quick reply.
I thought about the PendingIntent, but in this application the
information is only useful to the Caller if it is received while the
Caller is active that time. So if the information arrives later,
we'll still process it in the Service and store it for later use,
On further investigation, I see that the PendingIntent can be
cancelled, and such can work in the way I need by using a
BroadcastReceiver (probably dynamically registered).
