Bind service to activity in Android http://stackoverflow.com/questions/1916253/bind-service-to-activity-in-android then the system will retrieve the service creating it and calling its onCreate method if needed and then call its onStartCommand Intent int int method with the arguments supplied by the client. The service will at this point continue running until Context.stopService.. Note that multiple calls to Context.startService do not nest though they do result in multiple corresponding calls to onStartCommand so no matter how many times it is started a service will be stopped once Context.stopService or stopSelf is called however.. This likewise creates the service if it is not already running calling onCreate while doing so but does not call onStartCommand . The client will receive the IBinder object that the service returns from its onBind Intent method allowing the client..

START_STICKY tells the OS to recreate the service after it has enough memory and call onStartCommand again with a null intent. START_NOT_STICKY tells the OS to not bother recreating the service again. There is also a third.. also a third code START_REDELIVER_INTENT that tells the OS to recreate the service AND redelivery the same intent to onStartCommand . This article by Dianne Hackborn explained the background of this a lot better then the official documentation. Source.. only difference from previous versions of the platform is that it if it gets restarted because its process is killed onStartCommand will be called on the next instance of the service with a null Intent instead of not being called at all.
