Android Architecture NewsApp Sample

GitHub license

During Google I/O 2017, Android Team announced guidelines for architecture of Android app. This is just sample app explaining the new Architecture Guidelines written in Kotlin, YAY!

Components Demonstrated

What's the app about?

It's an extremely simple app which uses NewsAPI to show the latest news from Google News. It uses Retrofit 2 to fetch the news from the API and save them into database using Room. The main aim of this sample app is show how to use the new Architecture Guidelines with Kotlin.

Steps to run:

  • Go to NewsAPI and generate an API key (It's only 2 steps!)
  • Put the API key at the bottom of the gradle.properties NEWS_API_KEY = "YOUR_API_KEY"
  • Run the app
  • Enjoyyyyy 🎉

Architecture

The app uses ViewModel to abstract the data from UI and Repository as single source of truth for data. Repository fetch the data from database if it doesn't exist then it fetches from the webservice.
