" summary

Step-by-step recipe for a working custom Android system service: create AIDL in android.os that defines methods (example: add(a,b) and getServiceName), implement the generated Stub under com.android.server in the framework sources, add the AIDL to Android.mk, call addService via ServiceManager from SystemServer.java to publish an instance, add a unique name constant to Context.java and register the service/manager link so apps call getSystemService to obtain a manager that delegates over Binder. Requires rebuilding and flashing the system or using an AOSP-compatible device/emulator; example implementations return the expected results.
