Current State

Current State Implementation

• The app current builds and displays the user’s profile page successfully, and shows a browser page for searching for products.
• Users are able to update profile information (username, address, profile picture) and store the updated information to the server.
• Users are able to search for products on the browser page, filtering by name fragments.
• Product and Commission entities can be created successfully using Postman.

Known Deficiencies

• Three pages currently building, two of which are able to display and update information retrieved from the server.
• Updating Profile information causes the server to store strings with surrounding quotation marks.
• Order, ProductOnOrder, Image entities cannot be posted to the server.

Aesthetic Improvements

• We would like to design a more intuitive GUI with the use of floating action buttons and a dedicated Options menu.
• We would like to implement pop-out windows for images, expandable TextView sections, and other dynamic layout features.
• We would like to make the layouts more consistent in use of cards.
• We would like to experiment with colors and layouts more to give the app its own distinct look.
