Android developer roadmap,
from first principles
Twenty modules covering OS internals, Jetpack Compose, Kotlin Coroutines, Clean Architecture, Hilt, Room, and Google Play publishing. Written as a production path, not a template tour.
OS Stack Internals
Deep dive into Linux kernel boundaries, ART compilation lifecycles, and HAL structures.
Reactive Compose
Build pixel-perfect UIs with declarative UI architectures, custom layouts, and smart recomposition.
Layered Clean Architecture
Structure scalable projects using MVVM patterns, SOLID modules, and clean boundary controls.
Production Testing & Ops
Implement mock testing layers, profile memory leaks, encrypt databases, and automate releases.
The 20-module Android developer roadmap
Divided into 4 focused operational phases to take you from core foundations to advanced engineering.
Foundations
System architecture layer details, Kotlin compilation patterns, Gradle tasks, component activities, and XML layouts.
- 01 Ecosystem & Architecture
- 02 Kotlin Essentials
- 03 Build System & Structure
- 04 App Components
- 05 Activity Lifecycle
UI & Architecture
Dynamic layout configuration rules, declarative view state rendering with Compose, fragment backstacks, and MVVM routing.
- 06 Fragments deep dive
- 07 Jetpack Compose UI
- 08 Navigation & Intents
- 09 Lists & Recyclers
- 10 Layered Architecture
Data & Networking
Asynchronous flows, Hilt dependency injection graphs, Retrofit client layers, Room queries, and WorkManager task rules.
- 11 Coroutines & Flows
- 12 Dependency Injection
- 13 REST & Retrofit Client
- 14 Room DB Storage
- 15 Background Tasks
Production Practises
Unit test specifications, memory leak profiles, keystores encryption, custom build task plugins, and Google Play staging tracks.
- 16 Quality Assurance & Test
- 17 Profiler & Optimization
- 18 Security & Keystore
- 19 Build Tasks & Gradle
- 20 Publishing Operations
