Introduction

Android Development with Kotlin is the recommended path for building modern, reliable apps on Android. Kotlin’s concise syntax, null safety, and full interoperability with Java—combined with Jetpack libraries and Android Studio—help you deliver features faster with fewer bugs. This page outlines a hands-on curriculum to master Kotlin, UI development, app architecture, networking, persistence, testing, and publishing.

Course overview

You’ll start with Kotlin fundamentals, then learn Android UI via XML and Jetpack Compose. Next, you’ll structure apps with MVVM and Jetpack (ViewModel, LiveData/StateFlow, Room, Navigation), integrate REST APIs, handle offline-first storage, and add instrumentation/unit tests. You’ll finish with performance, accessibility, CI/CD, and Play Store release workflows.

Key learning outcomes

• Kotlin essentials: Data classes, coroutines, sealed classes, collections, and extension functions.
• UI development: Compose components, state management, theming, and responsive layouts.
• Architecture: MVVM with ViewModel, Repository, DI (Hilt), and clean module boundaries.
• Networking: Retrofit/OkHttp, JSON parsing (Kotlinx Serialization/Moshi), error handling, caching.
• Persistence: Room entities/DAOs, migrations, offline sync, and data flow with StateFlow.
• Testing & quality: Unit/Instrumented tests, Espresso, Robolectric, linting, and static analysis.
• Release readiness: App signing, ProGuard/R8, performance profiling, accessibility, and publishing.

Hands-on modules

• Module 1: Kotlin basics and coroutines with small console projects.
• Module 2: Android fundamentals — activities, fragments, lifecycle, and navigation.
• Module 3: Jetpack Compose — layouts, state, theming, and component patterns.
• Module 4: MVVM architecture — ViewModel, Repository, DI with Hilt.
• Module 5: Networking — REST integration, auth, pagination, and caching.
• Module 6: Persistence — Room, migrations, offline-first data sync.
• Module 7: Testing — unit, UI tests, test doubles, and CI integration.
• Capstone: Production-style app with analytics, error reporting, and Play release.

Starter project ideas

• Task manager: Compose UI, Room persistence, WorkManager for reminders.
• News reader: Retrofit API, paging, offline cache, dark mode, accessibility.
• Weather app: Location permissions, networking, theming, and widget support.
