What happens when a Android Service ( which is delivered as part of a .aar to multiple apps), is started by multiple apps?

Question

I have a .aar which has a android service ( named CommonService ) packaged in it. The .aar is delivered to two apps. Each app will perform startService() on this service.

Will there be two instance of the service running ? Following logs ( taken by executing adb dumpsys activity services CommonService ) suggest that two instances are running.

If I have to restrict the instantiation of the CommonService to one, is it possible when it is being delivered as part of a .aar?
