Assignment Details
For this assignment, you are required to create a simple shopping aid as an Android App. There should be a list of shopping lists and an inventory of the existing groceries. The app has a home screen that includes one or more decorative images and options (e.g. button, menu items, tabs etc.). The App has four main functions aside from the home screen:
- Allow user to view and manipulate grocery inventory.
- Allow user to view and manipulate shopping list items.
- Allow user to delete shopping list and/or grocery items.
- Allow user to view and manipulate images that are associated with grocery items.
For the purposes of this assignment the details of the items in the grocery inventory and shopping list should be stored in some kind of "database". For high marks this should be an SQLite database. For a basic pass, some kind of array, list or file structure is acceptable. Where the word database appears below it can refer to any of these types of structures, however refer to the marking guide to see what will attract high marks.
Please note that the application must have at least the elements described in this assignment specifications. You can implement features in higher levels (eg credit, distinction or high distinction) to gain marks even you skip some features in lower (eg pass) levels. The provided simple screenshots are for your reference only, you are encouraged to design your own look and feel for your application.
