Prerequisites
This series assumes you already know:
- Kotlin basics — variables, functions, classes, null safety, coroutines, Flow. If not, start with the Kotlin tutorial series.
- Compose basics — layouts, modifiers, state, lists, navigation, ViewModel. If not, start with the Jetpack Compose tutorial series.
How to Use This Series
Start from Tutorial #1 and go in order. Each tutorial builds on concepts from previous ones. By the end, you will know how to build, test, and deploy production-ready Android apps.
If you already know architecture basics, skip to Part 2 (Tutorial #6) for data and networking.
