Android Architecture Sample

This is just a sample app for news reading explaining the new Architecture Guidelines written in Kotlin. This sample app is powered by NewsAPI.

Components Used

• LiveData
• ViewModel
• Room Persistence Library

About App

This app uses NewsAPI to get various sources and each source can provide major headlines. It uses Retrofit 2 to fetch news sources and news headlines from the API and displays in a RecyclerView. It uses Room Persistence Library to provide offline functionality App first loads the data from DB and then checks for fresh data from API, API is only called if DB data is empty or expired The main aim of this sample app is show how to use the new Architecture Guidelines with Kotlin.

If you want 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 newsAPIKey = "YOUR_API_KEY"
• Run the app

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 and shows, while also checks if the data is old. If the data is old or database does not contain any data (such as first launch) it fetches data from Web Service and saves the data into database.

Future Roadmap

• Room Persistence Library for offline support
• Support for Launguage, Country and Category selection
• Write test cases

Proudly 💪 made in Kotlin
