Jetpack Compose Essentials: From Basics to Best Practices

Seminarziel

Participants will gain a comprehensive understanding of Jetpack Compose, including its core concepts, architecture, and the declarative UI paradigm. They will learn how to set up and configure Jetpack Compose in existing Android projects, create reusable composable functions, and manage state effectively within Compose. The seminar will cover essential topics such as theming, navigation, animations, and integrating Jetpack Compose with other Android components and libraries. Additionally, attendees will explore best practices for structuring Compose-based UIs, optimizing performance, and ensuring accessibility. By the end of the seminar, participants will be equipped to build modern, dynamic user interfaces using Jetpack Compose, enhancing their development workflow and the quality of their Android applications.

• Exercises
  • Exercise 1: Building a Responsive To-Do List App
    • Description: Create a to-do list application using Jetpack Compose, implementing features like adding, deleting, and marking tasks as completed. Ensure the UI is responsive across different screen sizes.
    • Result: Participants will develop a functional to-do list app, demonstrating their ability to create responsive and interactive UIs with Jetpack Compose.
  • Exercise 2: Implementing Navigation and State Management
    • Description: Extend the to-do list application by adding multiple screens (e.g., task details, settings) and implement state management using ViewModel and LiveData.
    • Result: Attendees will enhance their application with navigation and robust state management, showcasing their ability to handle complex UI interactions and data flows within Jetpack Compose.
