android onDestroy

is there a way i can delay the OS from killing my app... it runs in the background with a countdowntimer but its not a service... is there a way to raise its prioity or something so that it stay in the background for 开发者_如何学运维as long as possible and is still running when the application is resumed

An activity should only be displaying things to the user. Any processing should be done in a service.
