1

Kotlin Programming

3-4 weeks

Kotlin is the official Android language. Learn it properly: null safety, data classes, coroutines, and extensions make it a joy to write.

By the end, you'll be able to

  • Write Kotlin code with null safety and smart casts
  • Use data classes, sealed classes, and extension functions
  • Understand coroutines for async programming
🛠️

Mini-project

Build a CLI budget tracker in Kotlin: income/expenses, categories, monthly reports, and file persistence.

2

Android Fundamentals

3-4 weeks

Learn the Android framework: Activities, Fragments, intents, RecyclerView, and the Android lifecycle. Understand how apps actually work.

By the end, you'll be able to

  • Build multi-screen apps with Activities and Fragments
  • Display lists with RecyclerView
  • Handle the Android lifecycle correctly
🛠️

Mini-project

Build a note-taking app: create, edit, delete notes, categories, search, and offline storage with Room.

3

Jetpack Compose UI

3-4 weeks

The modern way to build Android UI. Learn Compose: declarative UI, state management, navigation, and theming. This is the future of Android.

By the end, you'll be able to

  • Build UIs with Jetpack Compose
  • Manage state with remember, ViewModel, and StateFlow
  • Implement navigation and theming in Compose
🛠️

Mini-project

Build a recipe app with Compose: recipe list, detail view, favorites, categories, and a beautiful Material 3 design.

4

Networking & APIs

2-3 weeks

Connect your app to the internet. Learn Retrofit, Ktor, JSON parsing, and how to handle network state gracefully.

By the end, you'll be able to

  • Fetch data from REST APIs with Retrofit
  • Parse JSON with Moshi or Kotlinx Serialization
  • Handle loading, error, and empty states
🛠️

Mini-project

Build a movie browser app: fetch from TMDB API, display trending/popular/search results, and cache with Room.

5

Architecture & Clean Code

2-3 weeks

Write maintainable Android code. Master MVVM, Repository pattern, dependency injection with Hilt, and clean architecture layers.

By the end, you'll be able to

  • Implement MVVM architecture with ViewModel and LiveData/StateFlow
  • Use Hilt for dependency injection
  • Structure apps with Repository and Use Case layers
🛠️

Mini-project

Refactor your movie app with clean architecture: data layer (API + Room), domain layer (use cases), presentation layer (MVVM).

6

Local Storage & Offline

2-3 weeks

Indian users often have poor connectivity. Learn Room database, DataStore, WorkManager, and offline-first architecture.

By the end, you'll be able to

  • Store data locally with Room database
  • Implement offline-first sync strategies
  • Schedule background work with WorkManager
🛠️

Mini-project

Make your movie app work offline: cache API responses in Room, sync when connected, show cached data when offline.

7

Firebase & Backend Services

2-3 weeks

Firebase is the fastest way to add backend features. Learn Auth, Firestore, Cloud Messaging, Crashlytics, and Analytics.

By the end, you'll be able to

  • Implement authentication with Firebase Auth
  • Store and sync data with Firestore
  • Add push notifications and crash reporting
🛠️

Mini-project

Build a chat app with Firebase: real-time messaging, user auth, push notifications, and read receipts.

8

Testing & Publishing

2-3 weeks

Ship to the Play Store. Learn unit testing, UI testing with Espresso, ProGuard, app signing, and Play Store optimization.

By the end, you'll be able to

  • Write unit tests and UI tests for Android
  • Configure ProGuard and sign your APK
  • Publish on Google Play Store with proper listing
🛠️

Mini-project

Polish your best app: add tests, optimize for size, create store listing with screenshots, and publish on Play Store.
