EC463 Software Mini Project

By Minseok Sakong ([email protected]) and Marcel Aubry ([email protected])

OBJECTIVES

• Create a full stack, cross-platform mobile application
• Use FDC API REST service to obtain calorie information of ingredients based off their barcodes
• Have the user enter Gmail authentication to save recipes to their respective accounts
• Store and manage data under Google Firebase
• Follow agile software development throughout the duration of the project

DESIGN DECISIONS

Front End

• User is prompted with a login screen that uses Gmail authentication to store data in their respective account
• Once access is granted, the user can select to scan a barcode or view their saved recipes
• When the scanner successfully scans the item, the user sees its calorie information retrived from the FDC database
• From there, the user is asked the amount of portions and can either add it to a recipe or scan another item
• Finally, the user has the option to view their saved recipes, and when clicked, they see the ingredients and total calories in that respective recipe

Back End

• When a barcode is scanned, its number is stored in a query object and requested to the FDC API
• The cURL command returns the information and is stored in an object which is then added to that user's database
• The item is also added to a recipe if the user decides to do so

TESTING AND RESULTS

Barcode Scanner

• The first test was to try out the barcode scanner
• To do this, we loaded the application onto our Android phone and used its camera to scan a Gatorade bottle
• The application successfully recognized the barcode and save its number as a string

API Calls from the Application

• Once we had the barcode number saved as a string, our next test was to load it into our query object and execute a cURL command
• The API returned the information requested

Firebase Storage

• Our next test was sending the acquired data to firebase and saving it within a user's collection
• The result was that once we pressed the smiley face icon, the item's information is sent to firebase
• Additionally, the data can be sent back upon request when the user taps the "View Recipes" button and selects a saved recipe

Gmail Account Login

• Through the creation of multiple pages, the Google account Login was implemented
• The result is that a user can now log in, access their respective data stored in their fire storage, and log out
