Versions

The app was implemented as a combination of 4 homework assignments, each containing different feature requirements.

Homework 1 (v0.0.1)

https://github.com/chubozeko/TaskRapid/releases/tag/v0.0.1

Required Features

• Created UI layouts and Navigation between Pages
  • Login
  • Home
  • Add Task
  • Sign Up
  • View Profile
  • Edit Profile
• Login page
  • A user can login to the app, with the User Profile credentials stored with SharedPreferences
• Home page
  • Task Type Tabs
  • List of Tasks (using LazyColumn)
  • TopAppBar with “View Profile” button
• Add Task page
  • Contains the main properties of a task (layout only)
  • Accessed when the user clicks on the FAB in the Home page

Additional Features (for bonus points)

• Account Creation (Sign Up page)
  • The user can create an account on the Sign Up page.
  • These credentials are stored in SharedPreferences.
• User Profile (View Profile & Edit Profile)
  • The user can view and edit their profile.

Challenges / Problems / Bugs

• Scrollability
  • Struggled to make the pages scrollable using Jetpack Compose, so I just resized everything to fit on one screen.
• Using SharedPreferences to store credentials
  • Not the best solution to store credentials, since it would only store them on the device itself rather than an external, encrypted database.
• Editing User Profile
  • Toast messages that were used for debugging should not appear when saving the changes to the Profile (business logic fix)
• Dark Mode
  • Fix colours used in Dark Mode for better visibility

Homework 2 (v0.0.2)

https://github.com/chubozeko/TaskRapid/releases/tag/v0.0.2

Required Features

• Add Task = page used for adding a new task
  • Task Name
  • Task Description
  • Task Date & Time
  • Task Type
  • Task Icon
• Edit Task = page used to update the selected task
  • Similar layout to Add Task, but with previously loaded task details
• Updated Task List Items
  • Used ConstraintLayout to design task list item layout
  • Added swipeable actions
• Used Room Database to store Task and TaskType details.
• Added a Date and Time Picker for assigning a date and time to a task
• Changed Task Types according to importance/priority:
  • Crucial
  • High
  • Medium
  • Low

Additional Features (for bonus points)

• Select a Task Icon
  • The user can select an icon that represents their task in the Add Task and Edit Task pages.
  • This icon can be seen in the task list on the Home page.
• Swipeable List Item
  • The user can swipe the task list item to perform Task actions:
    • Swipe Right = Mark Task as Complete/Incomplete
    • Swipe Left = Delete the Task

Challenges / Problems / Bugs

• Using Room to store task icons
  • Tried to implement the task icon list like the TaskDao and TaskTypeDao, but struggled to save the Material Icons (ImageVector) in the Room database.
  • Resolved by “hard-coding” the TaskIcon objects without Room.
• Implementing the Date & Time Pickers
  • Spent a while parsing the task dates and times in order to properly store them
• View Task page
  • Planned to add a View Task page that shows the details of the selected task, but there were issues with loading the task details due to its asynchronous nature (displays null values).
  • Opted to use the Edit Task page to view the current task details that could be edited.

Homework 3 (v0.0.3)

https://github.com/chubozeko/TaskRapid/releases/tag/v0.0.3

Required Features

• Added a Task Notification with options when a Task has a specified date and time
  • At Task Time
  • 5 minutes before Task
  • 10 minutes before Task
  • 15 minutes before Task
  • 30 minutes before Task
  • 45 minutes before Task
  • 1 hour before Task
• Added Bell icon for Tasks with notifications in Task list
• Integrated Maps API to add a location to the Task
  • Latitude
  • Longitude

Challenges / Problems / Bugs

• Scheduling Task Notifications with Work Manager
  • Struggled to schedule the upcoming tasks that have notifications activated
  • Possible solution: using the AlarmManager
• Incomplete implementation with Location
  • Unable to implement the Location-based capabilities in time (i.e. show a notification when the user is nearby the upcoming Task’s location)
• Duplicate Pin markers if multiple locations were selected (only the last selected location got saved)
