Full outline

Modern Android development: Kotlin, Jetpack Compose, architecture, data and networking, background work, and shipping to the Play Store.

01Kotlin & Platform
The language and the runtime it lives in.
- Kotlin
  Concise, null-safe, and the official language for Android.
- Android fundamentals
  The components and lifecycles the OS imposes on you.
- Jetpack Compose
  Declarative UI — the modern default over XML layouts.
- Architecture
  Structure that survives feature growth.
02Data & Delivery
Real apps talk to servers and survive offline.
- Networking
  Talking to APIs reliably on flaky mobile connections.
- Local storage
  Offline-first is a feature, not an edge case.
- Background work
  Android is aggressive about battery. Work with the system, not against it.
- Testing & release
  Getting it into users' hands and keeping it stable there.
