Yep startForeround() does what it says -- tells the system it should treat your service as if it is in foreground, something the user is aware of. A typical example is "background music playback," which needs to get as much CPU as it needs in order to avoid a bad user experience.
Generally, if you want your threads to run in the background, that would imply to me that your service is not one that wants to run in the foreground so should not be requesting to do so.
