When you start the same service again, it just has its onstart called: nothing changes. There's no such thing as a second service created, there's only one of them in memory.
Additionally: I think everyone has mentioned that services run on the main thread: how would one be running in the background and have another pop up. There's only one service, and as long as you send it messages it gets them. If you instead mean that you're having `onStart` delayed until the other one finishes, that's because it runs on the main thread. By the way, you shouldn't be doing anything in `onStart`, the same as how you shouldn't do anything blocking in activities. Again, you just *coordinate* threads using your service.
