Android Development Specialization

Build Android apps with Kotlin and Jetpack Compose: from the language and tooling through interfaces, state, persistence and publishing.

Android: Kotlin FundamentalsKotlin for developers who already know Python: val and var with type inference, deep null safety, functions with defaults and named arguments, data classes, when expressions, and collections with lambdas.50 minintermediate
Android: Android Studio & Your First AppInstall the real toolchain with honest numbers, generate a Compose app from the Empty Activity template, learn the job of every file the wizard leaves behind, add a dependency through the version catalog, and run your app on an emulator or a phone.45 minintermediate
Android: Jetpack Compose UICompose turns UI into a function of state: composable functions that run in any order, Column/Row/Box with ordered modifiers, Material 3 Scaffold screens, remember and mutableStateOf, state hoisting, @Preview, and LazyColumn lists that recycle with stable keys.50 minadvanced
Android: State, Lifecycle & ViewModelsRotation destroys the activity and everything it remembered: this lesson walks the six lifecycle callbacks and the promise each one makes, splits remember from rememberSaveable, hands screen state to a ViewModel that survives configuration changes, exposes it as a StateFlow collected with collectAsStateWithLifecycle, and ends with a checklist for where every value belongs.50 minadvanced
Android: Room, DataStore & PermissionsState that must outlive the app needs real storage: this lesson climbs the persistence ladder from in-memory through Preferences DataStore for small key-value settings to Room over SQLite - entities, DAOs returning Flow, KSP in Gradle, migrations - then adds runtime permissions requested the platform way, rationale before the second ask.50 minadvanced
Android Capstone — Build & Test a Notes AppFive lessons of pieces become one app: this capstone assembles a Notes app end to end - a Room-backed data layer, a repository mediating between the DAO and a DataStore sort-order preference, a ViewModel exposing one immutable UiState as a StateFlow, and two Compose screens that render it - then makes it shippable: unit-tested, UI-tested, accessibility-checked, signed and bundled for the Play Console's internal testing track.75 minadvanced
