Getting Started

Android Studio 3.6+

Prerequisite

• Android development knowledge with Lifecycle components like ViewModels and LiveData
• Kotlin
• Retrofit
• Room database
• Navigation component
• MVVM architecture

Branches and Projects

• master
  • This is the main/default branch that contains the following practice projects with Coroutines
    • ImageProcessingCoroutines
      • This project shows how to download an Image from a URL and then apply a "Black & White" filter on the image, all in the background using Coroutines.
    • CoroutinesRetrofit
      • This project shows how to download a list of Country information from a URL/endpoint in the background via a Coroutine, and then display it on a RecyclerView.
    • CoroutinesRoom
      • This project implements the First Time User Experience using Room as its backend to onboard and authenticate users.
      • Onboarding and Authentication of Users is done by communicating with the Room database in the background via a Coroutine.
    • CoroutinesFlowRetrofit
      • This project shows how to download a list of News items from a URL/endpoint in the background via Coroutine Flows, and then emit each News item with a delay in-between, in order to simulate a News Ticker.
      • The above Flow of News items is converted into a LiveData to show the result in a RecyclerView when the registered observer gets the update.
• idea_practice
  • This branch contains CoroutineConcepts project with easy to understand codes to establish each of the Coroutines concepts.
  • This is a separate IntelliJ IDEA project, hence it deserves a separate branch.
