Build an Expense Tracker App in Android | MVVM + Room Database + LiveData (2026)

🚀 In this video, you'll learn how to build a complete Expense Tracker App in Android using the MVVM (Model-View-ViewModel) architecture — the most recommended pattern by Google for Android development.

We'll cover everything step-by-step:
✅ Room Database (Entity, DAO, Database)
✅ Repository Pattern — Single Source of Truth
✅ ViewModel + LiveData for reactive UI
✅ Kotlin Coroutines for background operations
✅ RecyclerView with ListAdapter + DiffUtil
✅ ViewBinding — no more findViewById!

By the end, you'll have a real, working Android app that stores expenses locally, updates the UI automatically, and survives screen rotation!
