App Workflow

• Main Activity: Displays a list of items and includes buttons to add and edit items.
• Add/Edit Item Activity: This screen allows the user to input details of the item (name, quantity, and notes). If an item is being edited, the fields are populated with the existing item details.
• Database: Data is stored in an SQLite database accessed through a ContentProvider.

Core Features:

1. Add Item:

   • On the main screen, there is an "Add Item" button. Clicking it takes the user to the AddEditItemActivity where they can enter the item details.
   • If the item is new, the app adds it to the database.

2. Edit Item:

   • When the user clicks on an existing item in the list, they are taken to the AddEditItemActivity, where they can edit the details of the item.
   • After editing, the item is updated in the database.

3. Save Data:

   • When adding or editing an item, the data is saved in the database using ContentValues.
