Build a Modern Crypto App with Jetpack Compose & MVI (2026) | Real-Time Data with Retrofit

Описание: In this video, I walk you through the complete development of Kryptonite, a real-time cryptocurrency tracking Android application. We build this app using modern Android development standards, focusing on clean architecture, scalability, and high-performance UI.

This tutorial is perfect if you want to understand MVI (Model-View-Intent) architecture or learn how to create custom sparkline charts using the Jetpack Compose Canvas.

What you will learn in this video:

We build the app step by step, covering the entire Android architecture:

Jetpack Compose for building a modern, declarative UI
MVI Architecture for predictable and scalable state management
Real-time cryptocurrency data using Retrofit
Custom sparkline charts using the Compose Canvas
Infinite scrolling and pull-to-refresh functionality
Clean Architecture for long-term maintainability
Kotlin Coroutines and Flow for async and reactive data handling

This tutorial is suitable for intermediate developers who want to level up, as well as beginners who want to see how a real-world Android app is built from scratch.
