BTW, there's the [cw-android] Google Group for CommonsWare-specific questions like this: http://groups.google.com/group/cw-android > I am looking at the SystemServices example.

In that specific example? Not much. However, creating something where it *would* be important would add a lot of bulk to the example for little benefit. In general, you keep the device awake when you need to (e.g., to complete a download). > Is there a danger of the OS killing the > service while it's executing? In theory, yes, but the typical uses of an IntentService like this (alarms, app widget updates, etc.) mean that the service is very short-lived, so it is rather unlikely that Android will destroy it to free up RAM. > The reason I am asking is that I don't have a problem with obtaining > the WakeLock, other than it requiring another permission, which I > don't want to ask for unless there is a real good reason. If you don't mind the device falling asleep while you're doing your alarm-scheduled work, then don't use WakefulIntentService. But, if falling asleep could screw things up (e.g., middle of a database transaction, middle of a Web service operation), you'll want to keep the device awake. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 3.0.1 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
