Overview of Lifecycle-Aware Components

Introduction

Android UI controllers, such as activities and fragments, have a well-defined lifecycle, and their associated events are triggered during the lifecycle of the UI controller. While developing an application, it’s common practice to perform actions for dependent services and components in these lifecycles. Over time, these make the code cluttered and difficult to manage.

Recently, Google introduced the AndroidX lifecycle package to tackle this problem. This package provides interfaces that can be used to build components whose behavior can be modified based on the state of the parent UI controller.

In this lesson, we’ll learn about some key concepts to build lifecycle-aware components.
