Content Provider is part of my application?

I need to create 3 things:

• Content Provider
• Service
• Application

I'm wondering if these all three will be in one single project, or they will be three different projects?

Also how can I limit my Content Provider to my services and my applications?

They would be a single project. They are application framework objects and not as heavyweight as you might currently believe.

As far as permissions, check the security guide

To get more detailled answers maybe you could specify what type of "Content Provider", "Service" and "Application" you 'need' to create - and why..? ..a pay-for-content app..? ..a music-download portal..?
