Android App Development Training in Pune with Placement

Kotlin from a programmer-aware starting point, taught as a language in its own right before any Android API appears. Variables and types, null safety with `?.`, `?:` and the `!!` you learn to avoid, control flow, functions and default arguments, lambdas and higher-order functions, data classes, sealed classes and enums.

The idioms get real attention because they are what makes Kotlin code read as Kotlin: the scope functions (`let`, `run`, `apply`, `also`, `with`) and when each is the right one, extension functions, and delegation. Collections and the standard-library operators close the week.

The platform itself. Android Studio setup, the SDK manager, emulator configuration and physical-device debugging over ADB. Gradle 8+ with the Kotlin DSL — modules, build types, product flavours, version catalogues and dependency management, taught properly because Gradle is where most beginners lose days.

Then the app model: the project and resource structure, qualifiers for density, locale and orientation, the manifest, Activity and Application lifecycle, configuration changes and process death — the last of which is the source of the bug every Android interviewer asks about.

The modern Android UI toolkit, and the mental model shift it demands. Composable functions, the declarative model, and recomposition — what triggers it, what skips it, and why an unstable parameter quietly makes a screen slow.

State is the centre of the module: `remember`, `rememberSaveable`, `mutableStateOf`, state hoisting, and the unidirectional data flow that keeps a Compose screen predictable. Layout follows with Column, Row, Box, the Modifier system and its order-sensitivity, plus ConstraintLayout for Compose and lazy lists.

Making an app look and feel like a 2026 Android app. The Material 3 component set — app bars, navigation bars, cards, dialogs, bottom sheets, chips and the rest — used as a design system rather than a widget catalogue.

Theming covers colour schemes, typography and shape, light and dark mode, and Material You dynamic colour drawn from the user's wallpaper. Animation closes the week: `animate*AsState`, `AnimatedVisibility`, `Crossfade`, transitions and gesture-driven motion, with accessibility and reduced-motion handling treated as a requirement rather than an extra.

Moving between screens without losing state. Compose Navigation — the NavHost and NavController, route definitions, typed arguments, nested graphs and the back stack model that decides what a back press actually does.

Deep links and app links connect the app to the outside world, including the verification that makes an HTTPS link open your app rather than a browser. The module also covers passing results between destinations, bottom-navigation and drawer patterns, and adaptive layouts for tablets and foldables.

Production architecture. MVVM with AndroidX ViewModels — surviving configuration changes, `SavedStateHandle` for process death, and the UI-state modelling that keeps a screen's state in one immutable object rather than five loose flags.

Hilt supplies dependency injection on top of Dagger: modules, bindings, component scopes, `@HiltViewModel`, and qualifiers. The module closes on layered architecture — UI, domain and data — the repository pattern, and the use-case layer, including an honest note on when that layer is worth its indirection.

Asynchronous Android done correctly. Coroutines from first principles — suspend functions, `launch` and `async`, dispatchers and thread confinement, and structured concurrency with scopes, `supervisorScope` and cancellation that actually propagates.

Flow follows as the reactive stream type: cold flows, operators (`map`, `filter`, `combine`, `debounce`, `flatMapLatest`), `StateFlow` versus `SharedFlow`, `stateIn` and `shareIn`, and lifecycle-aware collection with `repeatOnLifecycle` — the idiom that stops a screen collecting in the background and draining a battery.

Talking to a backend. Retrofit for typed REST clients, OkHttp underneath with interceptors for authentication, logging and retries, and connection and timeout tuning for the unreliable networks Indian users actually have.

Serialization uses kotlinx.serialization or Moshi, with the schema-mismatch handling that stops a backend change crashing the app. Error handling is modelled explicitly as a sealed result type covering network, HTTP and parsing failures, and the module ends on token refresh, certificate pinning and mocking the API for tests.

Data that survives the app being killed. Room over SQLite — entities, DAOs, relations, type converters, and queries returning Flow so the UI updates automatically when the table changes. Migrations get proper time, including the destructive-migration shortcut and why shipping it costs users their data.

DataStore replaces SharedPreferences for key-value and typed preferences. The module closes on offline-first design: the database as single source of truth, cache invalidation, and a sync strategy that resolves conflicts deliberately rather than by luck.

Work that outlives the screen, on a platform that has spent a decade restricting exactly that. WorkManager for deferrable guaranteed work — constraints, chaining, unique work, expedited jobs and retry with backoff.

Foreground services and the Android 14+ service-type declarations follow, along with Doze, App Standby and the battery-optimisation behaviour that makes background work fail on some OEM devices and not others. Notifications close the module: channels, the runtime POST_NOTIFICATIONS permission, and Firebase Cloud Messaging for push.

Firebase as the de-facto mobile backend for Pune fintech and consumer apps. Firebase Auth across email, Google and phone-number sign-in — the last being the dominant flow in the Indian market. Firestore for real-time data with security rules written and tested rather than left open.

Crashlytics for crash reporting with custom keys and non-fatal logging, Analytics for funnels, Remote Config for feature flags and staged rollouts, and App Distribution for pre-release builds. The module includes reading a real crash report and fixing the bug behind it.

Tests that catch regressions rather than merely raising the coverage number. JUnit with MockK for unit tests, Turbine for asserting on Flow emissions, and fakes preferred over mocks where a fake is simpler to read.

Compose UI testing covers the semantics tree, finders, assertions and synchronisation — including the idling problem that makes flaky tests. Instrumented tests with Espresso, Robolectric for JVM-speed Android tests, and screenshot testing close the module, along with test doubles for Room and Retrofit.

The engineering that separates a shipped app from a good one. Macrobenchmark for startup and scroll performance, Baseline Profiles and Startup Profiles for faster cold starts, and the Compose-specific traps — unstable parameters, unnecessary recomposition, and `derivedStateOf`. Memory profiling and leak detection with LeakCanary.

App size is treated as a feature, since download size measurably affects install rates in India: R8 shrinking and obfuscation, resource shrinking, and App Bundle splits. Security closes the module — runtime permissions, scoped storage, EncryptedSharedPreferences and keeping secrets out of the APK.

Getting the app into users' hands and keeping it there. Signing configuration and Play App Signing, the Android App Bundle versus the legacy APK, and versioning strategy. The Play Console flow end to end: store listing, content rating, the Data Safety form, target-API requirements and the policy checks that reject a first submission.

Release tracks — internal, closed, open and production — with staged rollouts and halting a bad release. CI/CD with GitHub Actions builds, tests, signs and uploads a bundle automatically, and Play Vitals is read as the production feedback loop.

Full-time capstone work followed by structured interview preparation. You build and publish a complete Android application — Compose UI, MVVM with Hilt, a Room-backed offline-first data layer, Retrofit networking, WorkManager background sync, Firebase push, tests, and a signed bundle on an internal Play track.

Interview preparation matches how Pune Android panels actually run: a Kotlin and coroutines round, an Android-internals round covering lifecycle, process death and memory, and a UI round on Compose. Resume, LinkedIn and GitHub polish included.
