Separate Project for Database

I want to separate my database logic from the main app. From the app, I want to access this for database related task. This project won't have any views or activity just database related task.

I'm not sure what is the best way to accomplish this with Android. Can anyone suggest what should I use to accomplish this?

EDIT:

I want to create a database which will be shared among multiple app. They are independent app, but they will have same database structure. In .NET I would create a separate project in the solution to house the business logic. I am trying to implement something similar in Android.
