Screenshots

Features

• MVVM Architecture + Repository design Pattern.
• Jetpack Libraries and Architecture Components.

Prerequisites

Add your TMDB API key in the local.properties file:

tmdb_api_key=YOUR_API_KEY

Testing

Local unit testing is done for Repository and ViewModel layers. UI testing is done for screens with pagination using Espresso.

Libraries

• Android Jetpack
  • Paging Library helps you load and display small chunks of data at a time. Loading partial data on demand reduces usage of network bandwidth and system resources.
  • Compose Android’s modern toolkit for building native UI.
  • ViewModel ViewModel is designed to store and manage UI-related data in a lifecycle conscious way. This allows data to survive configuration changes such as screen rotations.
  • DataBinding is a Library in the support library that allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.
  • LiveData is lifecycle-aware, meaning it respects the lifecycle of other app components updating app component observers that are in an active lifecycle state.
• Glide is an image loading and caching library for Android.
• Dagger is a fully static, compile-time dependency injection framework for Java, Kotlin, and Android.
• RxJava is a library for composing asynchronous code using observable sequences.
• RxAndroid is a module that adds the minimum classes to RxJava to make writing reactive components in Android.
• Kotlin coroutines Executing code asynchronously.
• StateFlow is a state-holder observable flow that emits the current and new state updates to its collectors.
• Coil-compose An image loading library for Android backed by Kotlin Coroutines.
• Retrofit is a Type-safe HTTP client for Android, Java and Kotlin by Square.
• Gson is a serialization/deserialization library to convert objects into JSON and back.
• OkHttp interceptor Logs HTTP requests and responses.
• Material Design Build beautiful, usable products using Material Components for Android.
• MotionLayout helps to manage motion and widget animation.
• Mockito which is the most popular Mocking framework for unit tests written in Java as well as Kotlin.
• MockK mocking library for Kotlin
• Espresso Automated testing UI test
