This project provides a comprehensive WhatsApp clone for Android, showcasing modern development practices with Jetpack Compose and Stream's Chat and Video SDKs. It's an excellent resource for developers looking to implement real-time messaging and video calling features, demonstrating best practices in UI design, architecture, and background task management.

How It Works

The application leverages Jetpack Compose for its entire UI, enabling declarative and efficient UI development. It integrates Stream Chat SDK for real-time messaging and Stream Video SDK for WebRTC-based video calls. The architecture follows Google's official guidance, employing a two-layer structure (UI and Data) with unidirectional data flow, utilizing Hilt for dependency injection, Coroutines for asynchronous operations, and Room for local data persistence.

Quick Start & Requirements

• Install/Run: Clone the repository and create a secrets.properties file in the root directory with your Stream API key (STREAM_API_KEY=YOUR_API_KEY). Build and run using Android Studio.
• Prerequisites: Android SDK (minimum 21), Kotlin, Jetpack Compose, Hilt, Coroutines, Stream Chat SDK, Stream Video SDK.
• Setup: Requires obtaining a Stream API key from getstream.io.
• Docs: Blog posts detailing architecture and Compose themes are available: Part 1, Part 2.

Highlighted Details
