Libraries Used

• Architecture - Start with classes for managing your UI component lifecycle and handling data persistence.

  • lifecycle - As a user navigates through, out of, and back to your app, the Activity instances in your app transition through different states in their lifecycle.
  • ViewModel - Easily schedule asynchronous tasks for optimal execution.
  • livedata - is an observable data holder class. Unlike a regular observable, LiveData is lifecycle-aware, meaning it respects the lifecycle of other app components, such as activities, fragments, or services.
  • Navigation - Handle everything needed for in-app navigation. asynchronous tasks for optimal execution.
  • Data Binding - The Data Binding Library is a support library that allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.
  • Coroutines - A coroutine is a concurrency design pattern that you can use on Android to simplify code that executes asynchronously.
  • Room - The Room persistence library provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
  • SQLite - The androidx.sqlite library contains abstract interfaces along with basic implementations which can be used to build your own libraries that access SQLite.

• UI - Details on why and how to use UI Components in your apps - together or separate

  • Layout - Lay out widgets using different algorithms.
  • Grid Layout - A layout that places its children in a rectangular grid.
  • Swipe-to-Refresh Layout The swipe-to-refresh user interface pattern is implemented entirely within the SwipeRefreshLayout widget, which detects the vertical swipe, displays a distinctive progress bar, and triggers callback methods in your app.

• Third party and miscellaneous libraries

  • Retrofit for turns your HTTP API into a Java interface
  • Glide for image loading framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.
