Android 2.2 - User Profile Application

Hi All, I am looking to add a user profile system to my android app so that users can switch between profiles, manage the add/edit/delete of profiles and record some basic information against the profile. The application needs to record back to a SQLite database which can be fairly basic in design. I will require the application files so that I can eventually add this to my own application. I will not require help to do this as part of the project but the application should ideally be commented enough to allow this. Thank you for taking the take to look at my project. Please look at the attached spec document and let me know if you have any questions. Regards Cam
