StudentProductivityApp

Midterm Presentation Guide: Student Productivity App

1. Project Overview & Core Functionality

The Student Productivity App is a centralized hub designed to help students manage their academic life.

Current Status: The app is stable, follows a modular architecture, and features a functional navigation system.

Working Features:

Assignment Tracker: Full CRUD operations for student tasks using a local database.

Canvas API Sync: Access Token based retrieval of "To-Do" items from Idaho State University’s Canvas instance (allowed with FERPA according to ISU IT department recommendation)

Interactive Campus Map: Integrated WebView with interactive ISU map capabilities.

PDF Scanner (OCR): Ability to scan documents and extract text to automatically create assignments.

Video Lecture Tool: Transcript search and synchronized video playback.

Notification Tool: Reminds user of assignment due dates in advance

2. Code Structure & Architecture

The project follows a Feature-Based Package Structure, separating concerns and ensuring scalability.

Activities & Fragments:

MainActivity: Uses a BottomNavigationView to swap between HomeFragment and ScheduleFragment.

CampusMapActivity, VideoLectureActivity, PdfHubActivity: Dedicated activities for specialized, full-screen features.

Navigation: Uses Intents for activity transitions and FragmentTransactions within the MainActivity for a seamless hub experience.

Separation of Concerns: Logic is separated into:

features/: Organized by functionality (assignments, campus_map, pdf_scanner, video_lectures).

database/: Room persistence layer.

viewmodel/: State management and business logic.

3. Data Handling & Background Work

Local Storage (Room DB):

Uses Room to store assignments (Assignment.kt).

Uses Flow and LiveData to ensure the UI updates automatically when data changes (Reactive UI).

Local Storage (SharedPreferences): Used for lightweight user state, such as the login status ("Jerry").

Remote API (Retrofit):

Connected to Canvas LMS.

Uses Coroutines (lifecycleScope.launch) to perform network calls and database operations on background threads, preventing UI "jank" or freezing.

OCR & AI: Uses Google ML Kit for text recognition and document scanning.

4. UI / UX Implementation

RecyclerView: Used in HomeFragment and ScheduleFragment to display lists efficiently. It utilizes ListAdapter and DiffUtil for optimized UI updates.

ConstraintLayout: Used across all XML files to ensure a flat view hierarchy and responsive design across different screen sizes.

Custom Styling: Implemented a selectable dark/light theme using ISU's brand colors (Orange/Black/Gray/White) under Settings (Wrench Icon).

5. Technical Stack (Libraries Used)

Jetpack Room: Local SQLite abstraction.

Retrofit & Gson: For API communication and JSON parsing.

ML Kit: For Document Scanning and Text Recognition.

CameraX: For a custom, high-performance camera interface.

Material Design 3: For modern UI components (Buttons, DatePickers, Nav Bars).
