Roadmap to building native Android applications using Kotlin, Jetpack Compose, architecture, APIs, storage, testing, and Play Store release practices.
Complete the Kotlin and Android Foundations branches before moving ahead.
Learn variables, functions, classes, data classes, collections, null safety, exceptions, and idiomatic Kotlin.
Use suspend functions, coroutine scopes, dispatchers, flows, and structured concurrency for responsive apps.
Understand activities, lifecycle, intents, permissions, resources, Gradle, manifests, and app structure.
Build a simple Kotlin app with multiple screens, lifecycle-safe state, input validation, and polished UI.
Complete the Modern Android UI branches before moving ahead.
Use ConstraintLayout, RecyclerView, ViewBinding, themes, resources, and responsive layouts.
Build declarative UI with composables, modifiers, state hoisting, navigation, forms, lists, and theming.
Rebuild one real app screen in Compose, handle loading/error/empty states, and test it on two screen sizes.
Create a Compose UI with transactions, filters, charts, empty states, and local preview data.
Complete the Architecture, APIs, and Data branches before moving ahead.
Use ViewModel, repository pattern, UI state, dependency injection, navigation, and clean module boundaries.
Call REST APIs, parse JSON, model errors, cache data, retry safely, and keep secrets out of the client.
Store structured data, preferences, cache API responses, handle migrations, and support offline-first flows.
Build a news app with API fetch, Room cache, Compose UI, saved articles, search, and error recovery.
Complete the Testing, Performance, and Release branches before moving ahead.
Write unit tests, UI tests, ViewModel tests, fake repositories, and regression checks for core user flows.
Profile startup, memory, jank, battery, secure storage, permissions, network security config, and release signing.
Ship a polished app with offline data, tests, release build, privacy notes, screenshots, and a Play Store-style listing.
Build and test a habit tracker with local persistence, notifications, analytics-ready events, release build, and documentation.
