android - Service.onDestroy() is called directly after creation, anyway the Service does its work

I built a Service and it didn't work as expected, so I debugged it. During debugging, I saw that the service's onDestroy() method is called directly after returning from onCreate(). When I comment out the cleanup that happens in onDestroy(), the service does its work, but this should not be my solution. So my question is, why is onDestroy() called so early and why is the service running anyway? Or how can I prevent onDestroy() from being called at the wrong time?

For your information: I've subclassed IntentService.

Thanks for any help.

If you are subclassing IntentService you should be using onHandleIntent(Intent intent) for the lifecycle of your service. Your service might be moving to onDestroy quickly becuase you do not have code inside of onHandleIntent. Although without your code I cannot say for sure.

Also it might aways move to onDestroy quickly because IntentService is auto threaded for you and might just launch the worker thread which calls onHandleIntent and move to onDestroy.
