Study Notes

Mobile App Development Lifecycle

  • Mobile app development lifecycle follows similar phases as web or desktop application development.
  • The five phases are:
    • Inception: Idea generation and refinement.
    • Design: Defining user experience (UX) and user interface (UI) design.
    • Development: Building the app.
    • Stabilization: Testing and debugging the app, often with limited beta phases for user feedback.
    • Deployment: Delivering the app to users.

.NET MAUI: Cross-Platform Framework

  • .NET MAUI is a cross-platform framework for building native mobile and desktop apps using C# and XAML.
  • It supports Android, iOS, macOS, and Windows platforms.
  • .NET MAUI provides a unified API for all platforms.
  • It offers deep access to native platform functionalities while enabling a write-once, run-anywhere experience.

.NET MAUI Architecture

  • .NET MAUI provides a single project system for developing UIs for mobile and desktop applications.
  • App code mainly interacts with .NET MAUI API, which then accesses native platform APIs.
  • Optionally, app code can directly interact with platform APIs for specific functionalities.

.NET MAUI Features

  • Provides a set of controls for displaying data, initiating actions, indicating activity, and more.
  • Includes an elaborate layout engine for designing pages.
  • Supports different page types for rich navigation, including drawers.
  • Enables data-binding for more elegant and maintainable development patterns.
  • Offers customization of handlers for enhanced UI element presentation.
  • Provides cross-platform APIs for accessing native device features (e.g., GPS, accelerometer, battery status, network state).
  • Offers cross-platform graphics functionality, providing a drawing canvas for shapes, images, and graphical transforms.
  • Features .NET hot reload, allowing modification of XAML and managed source code while the app is running without rebuilding.

Accessing Device Features with .NET MAUI

  • Provides APIs for accessing device sensors (e.g., accelerometer, compass, gyroscope).
  • Allows checking network connectivity status and detecting changes.
  • Offers information about the device running the app.
  • Enables cross-app text copying and pasting to the system clipboard.
  • Provides file picking functionality.
  • Securely stores data as key/value pairs.
  • Utilizes built-in text-to-speech engines for reading text from the device.
  • Supports browser-based authentication flows with callback to app-registered URLs.

.NET MAUI Single Project

  • Provides a unified project system for targeting Android, iOS, macOS, and Windows platforms.
  • Simplifies and streamlines cross-platform development.
  • Offers features like:
    • A single shared project for all platforms.
    • Simplified debug target selection.
    • Shared resource files.
    • Single app manifest for configuration.
    • Access to platform-specific APIs when needed.
    • Single cross-platform app entry point.
