Project characteristics

This project brings to table set of best practices, tools, and solutions:

• 100% Kotlin
• Model-View-View Model Architecture
• Android Jetpack
• Dependency Injection
• Material design

Tech Stack.

• Kotlin - Kotlin is a programming language that can run on JVM. Google has announced Kotlin as one of its officially supported programming languages in Android Studio; and the Android community is migrating at a pace from Java to Kotlin
• Lifecycle - Perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
• Viewmodel -The ViewModel class is designed to store and manage UI-related data in a lifecycle conscious way
• LiveData - A lifecycle-aware data holder with the observer pattern
• Kotlin Coroutines - A concurrency design pattern that you can use on Android to simplify code that executes asynchronously.
• View Binding - Allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.
• Retrofit - Retrofit is a REST Client for Java and Android by Square inc under Apache 2.0 license. Its a simple network library that used for network transactions. By using this library we can seamlessly capture JSON response from web service/web API.
• GSON - JSON Parser,used to parse requests on the data layer for Entities and understands Kotlin non-nullable and default parameters.
• Flow - In coroutines, a flow is a type that can emit multiple values sequentially, as opposed to suspend functions that return only a single value.
• Hilt - A dependency injection library for Android that reduces the boilerplate of doing manual dependency injection in your project
• Logging Interceptor - logs HTTP request and response data.
• Material Libarary - Modular and customizable Material Design UI components for Android
• Glide- An image loading and caching library for Android focused on smooth scrolling.
