AAC Paging Infinite Scrolling With Network Sample

This project is a sample for implementation of Clean Architecture written in Kotlin. It uses Jetpack's Paging component to demonstrate endless scrolling using database + network.

What you will learn?

  1. Clean Architecture: Design an app using layered architecture based on Clean Architecture by Uncle Bob.
  2. Paging library: Learn how to use PagedList callbacks to coordinate between local database and fetching more data from network.
  3. Navigation component: At last it's settled, single activity is what's Google recommend now. Navigation editor make things easy for us to design navigation path of our app.
  4. Architecture components: The good old tristar LiveData, ViewModel and Room.
  5. Kotlin: We all love it. Learn how to use it to develop an Android app.
  6. Dagger 2: Dependency injection help us to abstract the creation of a dependency. Dagger 2 further helps to manage the dependencies in an optimal way.

Pre-requisites

Android Studio 3.2 or higher

Getting Started

The app requires an API key from The Movie Database (TMDB) which you can get using free registration. https://www.themoviedb.org/settings/api

You can add the key in your global .gradle/gradle.properties file.

Ex: TMDB_API_KEY="YOUR-API-KEY"

OR

you can replace the TMDB_API_KEY in build.gradle (Module: app).

Ex: it.buildConfigField 'String', 'TMDB_API_KEY', "\"YOUR-API-KEY\""
