Task Rapid

Task Rapid is a mobile assistant app that keeps track of the user's tasks. This was developed with Kotlin for the Mobile Computing (521045S) course at the University of Oulu.

Tools used

  • Android Studio 2021.2.1 (Chipmunk)
  • Android SDK 11.0 (API Level 30)
  • Kotlin
  • Canva (for graphics)

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)

Homework 4 (v0.0.4)

*Not implemented before deadline
