Well, if the service is nuked from orbit via a task killer, alarms definitely go away. If the service is stopped conventionally (e.g., stopService(), stopSelf()), alarms definitely stay. You can see this with the WakefulIntentService demo code -- IntentService calls stopSelf() when there is no more work to do. I am uncertain what happens if Android decides to stop the service due to insufficient memory, because I have no idea how to reproduce that situation. > If you are registering alarms in a service, a) the service must remain > running in order for them to remain registered This is absolutely positively not true.

Manifest-registered BroadcastReceivers are "no longer running" as soon as onReceive() ends. > (if the service is killed by a Task Killer, or by the system due to > memory constraints) > -In the service onDestroy() method, cancel the alarms, and trigger the > BroadcastReceiver (which will recursively call the Service, and re- > register the Alarms). If the service is killed by a task killer, your process is terminated, and you do not get control in onDestroy(). The process may also be terminated as part of the emergency memory reclamation efforts of the OS. -- Mark Murphy CommonsWare mmur...@commonsware.com http://commonsware.com -- You received this message because you are subscribed to the Google Groups "Android Discuss" group.
