Android Basics in Kotlin

Discover what Android is, where it runs, why it's open source, and get introduced to the tools and SDK used to develop Android applications.

Explore Android Studio, its project structure (manifests, code, resources), and Gradle—the build system essential for creating, organizing, and running Android apps.

Set up Android Studio, create and run your first "Hello World" app, explore project structure, and customize the app icon to establish your Android development environment.

Explore the basics of Kotlin: syntax, data types, functions, scope, operations, and collections, laying the groundwork for modern Android app development.

Practice using variables, data types, operations, and functions in Kotlin. Apply concepts by building and testing a smart calculator app with functions and conditional logic.

Learn how to use Kotlin collections to store, loop through, filter, and transform data, then apply these concepts by building a functional shopping cart system.

Learn object-oriented programming concepts: classes, objects, properties, behaviors, encapsulation, inheritance, polymorphism, abstraction, composition, and data classes in Kotlin.

Learn to build, encapsulate, extend, and reuse classes in Kotlin using inheritance and polymorphism. Apply concepts by designing vehicles that delegate behavior to engines in a coding exercise.

Explore the Android platform: architecture layers, core app components, the Manifest file, Intents, permissions, and building secure, user-focused Android apps.

Learn how Android manages Activity lifecycles, how to respond with lifecycle callbacks, and ensure smooth state preservation during interruptions or configuration changes.

Explore Android Activity lifecycles, understand state loss on recreation, and learn how to preserve user data using lifecycle methods and state saving techniques.

Learn the fundamentals of Android XML layouts: view hierarchy, LinearLayout, weights, styles, resources, and adapting layouts for different devices, languages, and themes.

Learn to design Android screens using XML and the Layout Editor. Preview, style, and build responsive UIs visually and through code, completing a hands-on layout exercise.

Learn to organize Android layouts with reusable styles, resource files for colors, strings, and dimens, and enable theming and dark mode for a maintainable, adaptive UI.

Explore how Android apps handle user interactions: connecting layouts to code, using listeners for events, collecting input with EditText, and providing responsive feedback.

Learn how to connect UI XML with Kotlin, handle user input, validate data, update views, and provide real-time feedback to make Android apps interactive.

Understand Android navigation patterns, the back stack, Back vs Up buttons, intent-based navigation, and how to configure deep links for direct screen access.

Learn multi-screen app navigation in Android: use explicit and implicit Intents to pass data and share content between Activities, building a simple two-screen music app.

Learn what Fragments are in Android, how they provide reusable UI sections within Activities, their lifecycle, usage, and when to use them for flexible, modular app design.

Learn to refactor an app using Fragments for responsive layouts, manage navigation, pass data via arguments, and support both phones (single-pane) and tablets (two-pane) in Android.

Learn the concept of custom views in Android, how to build reusable UI components, manage their lifecycle, and their role within Activities and Fragments for consistent, maintainable UIs.

Learn to create reusable custom views in Android to simplify UI code, improve modularity, and handle shared behaviors like favorite state in components.

Learn how to debug Android apps by identifying, investigating, and resolving crashes, logic errors, and layout issues using Logcat, the debugger, and practical troubleshooting steps.

Learn how to localize Android apps by using string resources, supporting multiple languages, proper formatting, and testing to create culturally adaptable, accessible user interfaces.

Discover UI design principles by exploring Material Design's philosophy, components, and theme system to create cohesive, accessible, and professional Android app interfaces.
