However... even in a service, never ever do long work on the main thread (where the Service class callbacks happen) -- there could well be some other thing that gets scheduled for your app (starting an activity, delivering a broadcast) that will get blocked by what you are doing and cause an ANR/death. 5 seconds for a service to start is actually well out of bounds of what you should be doing. That is enough to cause an ANR if the user tries to do anything with your app while the service is starting. Another thing to watch out for is initialization time of your process -- when your process isn't already running and it needs to launch an activity, service, or receiver. The timeouts are based on the time from when the system decide to run one of these thing to when it completed, so if your process initialization time is slow then it can cause these timeouts to expire. The main things to look for is any work done in creating your Application object or any of the content providers running in your process, all of which must be initialized before the first activity, service, or receiver can be run.

Also note that you should NOT be basing any of this on behavior on the emulator, since the speed of the emulator varies greatly depending on the computer it is running on. On a modern fast computer, it can run significantly faster than a real device. This is why you must always always test on a device. You just can't predict how well your app will really run until you do so. -- 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.
