Let's say I develop an application which is using Bluetooth Manager Service which is in AOSP. But if I add a new hardware and create a HAL, AIDL, JNI, Framework Service for that hardware, will it works the same way if try to access that service or will there be any changes.

I was creating an application which uses service written by me. But i want to know how to access that service in by application code. How to add that service in AOSP
