How many threads a service / process has "inside" does not have any effect on how likely it's to be killed.
You should expect that your app's entire process, including any services (and threads, of course) can be killed by the system any time. Now since you mentioned swiping -- in case you're running 4.4, it appears to have a bug where swiping kills the process. In general, maintaining an ever-running service is not an easy task, unless you use the official "startForeground" API (which by design puts an icon into the status bar). Some (say, Mark Murphy who doesn't appear to be on this list anymore), would call it an "anti-pattern". I tend to agree. -- K 2014-02-01 dashman <[email protected]>: > I think your analysis is correct. > > I also think it happens because my service doesn't create a worker thread. > > In the onStartCommand() method - it sets up some system listeners and > returns STICKY. > > So when the main app is being killed (when i remove it from the active > apps list) - i think the service > is being killed - but the onDestroy is not being called (as you mentioned). > > I verified with the ps command - and it's gone. > > So should I create a worker thread or a handler - i will use it later on > for some work. > > > > > > On Friday, January 31, 2014 3:01:28 PM UTC-5, Kostya Vasilyev wrote: >> >> >> 2014-01-31 dashman <[email protected]>: >> >> >>> What's confusing is this. >>> >>> I've got the app and service running. >>> >>> Then using the active app-list option of the launcher, I remove the app. >>> >>> >>> I would think this would kill the app - but not the service. >>> >>> Service.onDestroy() is not called. >>> >>> >>> But now if I restart the app - the Service.onCreate() is called >>> >>> >> Sounds like your app's process gets killed.
