[Q] How would I find out to which package a service belongs? topic

Hi,
I want to disable my Proximity Sensor. I know it's service name, "ProxymitySensorManager", because Better Battery Stats lists it.

I understood, that i can disable services with adb by using "am stopservice packagename.servicename".
This is my problem. How would I find out the packagename my service is a child of?

Thanks a lot.
