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.
