Oh sure, if you are going to do some longer-running -continuous- work then use a service. Don't use a service to sit there and do nothing but schedule future work (which is what you seemed to be describing in your first post). The widget example on the developer blog uses a service as well, but does not call Service.stopSelf() when done. Hm. Bad sample code! No cookie! I'll see about getting that fixed. In the meantime, consider stopping a service when it is done with its work to be a Good Thing. :} -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

Don't use a service; use the alarm manager to schedule your wakeup/work.

Following the source examples out there, it seems the common solution is to use a service to prepare the updates. However, after I am done, my process is still running on service level, it looks like it's not being killed by Android in low memory conditions, and killing it manually causes it to restart. The same seems to be true for all other widgets I have installed so far - they stay in memory. Wouldn't it be better to have to service call this.stop() when it is done, at least if the widget knows it probably won't need to do another update any time soon? I'm doing this now, and it seem to work fine - my process is being killed when Android needs memory. I'm confused though as to why this wouldn't be the encouraged behaviour then (it's not like the G1 has an aweful lot of memory to spare). Should or shouldn't I be doing this? -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

Don't use a service; use the alarm manager to schedule your wakeup/work. Currently I'm actually using the widget framework's update mechanism. From what I understand, a service must be used in any case to avoid ANR when processing the request might take a bit longer. The widget example on the developer blog uses a service as well, but does not call Service.stopSelf() when done.
