Design Considerations

User Interface

• Material Design:

  • Applied Android's Material Design components like MaterialButton, TextInputLayout, RecyclerView, and CardView.
  • Material themes are set in the styles.xml file with Theme.MaterialComponents.* themes, using predefined styles from Google’s Material Design library.

• Responsive Layout:

  • Designed for various screen sizes and orientations with ConstraintLayout.
  • Separate XML layout files are created for different configurations (e.g., res/layout, res/layout-large).
  • ViewModel and LiveData are used to handle configuration changes seamlessly.

• Accessibility:

  • Ensures usability for people with disabilities, including support for screen readers and high-contrast themes.
  • Important visual elements have content descriptions.
  • Text sizes are adjustable using sp units, with android:autoSizeTextType applied to TextView.

Performance

• Optimized API Calls:
  • Reduced latency with efficient network handling.
  • Implemented caching strategies using OkHttp's built-in caching for offline network responses.

Security

• Secure Connections:
  • Enforced HTTPS for all network communication to maintain data security.

Integration

Third-Party Services

• Analytics:
  • Integrated Firebase Analytics for tracking user engagement.

Local Data Storage

• Room Database:
  • Used for local caching of user preferences and data.

Backend API Integration

• Retrofit:
  • Utilized for efficient HTTP communication.
• OkHttp:
  • Manages network requests, with GSON used for JSON parsing to facilitate smooth backend API integration.

Testing

• Testing Configuration:
  • Configured with dependencies like JUnit and Espresso to ensure comprehensive test coverage.
