A modern news consumption application that transforms traditional articles into engaging multimedia experiences.
Technical Overview
NewsSound is a Kotlin Multiplatform Project that combines traditional article reading with modern multimedia experiences, including text-to-speech, video integration, and story-like presentation.
Architecture & Design Patterns
-
Kotlin Multiplatform Project (KMP) - Sharing code between Android and iOS platforms
-
Repository Pattern - Abstracting data sources (e.g.,
ForYouRepository) -
Dependency Injection - Custom DI implementation with provider functions and singletons
-
Factory Pattern - Creating different types of UI components based on content type
-
Strategy Pattern - Multiple TTS service implementations with fallback mechanism
-
Observer Pattern - For UI updates and data flow
-
Adapter Pattern - Converting data models for different UI representations
-
Builder Pattern - For constructing complex objects like API requests
Programming Languages & Frameworks
-
Kotlin - Primary language for Android and shared code
-
Gradle KTS - Build configuration with Kotlin DSL
-
Coroutines - Asynchronous programming
-
Ktor - Networking library for API calls
-
Kotlinx Serialization - JSON parsing
Key Features
Story Viewer Experience
The app transforms traditional articles into engaging story experiences similar to popular social media platforms.
Advanced Text-to-Speech Integration
Multiple TTS services (Zalo, Viettel, Knet) with fallback mechanism ensure reliable audio narration.
Article Preview with Dynamic Timing
Intelligent calculation of reading time based on content length.
Content Parsing and Extraction
Sophisticated parsing to extract meaningful content from web sources using JSoup and custom extractors.
Adaptive UI for Different Content Types
UI adapts based on content type, providing optimal viewing experiences for various news formats.
