Is there just one PID for an application and the services it loads

Hi,

I have an android application that loads three services.  The application itself runs in the background with the three services.  I am wanting to do some CPU usage measures for the application and the three services.  I had placed the code that gathers the metrics that I am using in one of the services.  It occurred to me that the PID that I am getting me only be for the service.  I was hoping someone might know exactly how this works.  Does the application and the three services each have there own PID or is there one PID shared between the application and the services?  If I have not given enough information to answer this question, let me know and I will do what I can to supply more info.

Thanks

Not a specific answer to android, usually.
Each application at the time of running has a unique ProcessID. When it exits and after enough time has passed, the PID numbers are reused..
The PID is assigned by the system.
As to your question, a process starts and gets a process ID of 1234 it then starts three additional services/processes 2345, 2346, and 2347
The parent process ID (PPID) of each of these three will be 1234.
