LiveData and LiveData Observers
Explore how to implement LiveData and LiveData observers with ViewModel to keep your Android app's UI updated automatically. Understand how lifecycle-aware components reduce memory leaks and improve app stability by ensuring updates occur only when the activity is active.
Introduction
The LiveData class is one of the Android architectural components that helps keep the UI up to date with the latest data every time it changes. This class reduces the need for manual data updating every time new data becomes available.
ViewModel and LiveData are both lifecycle-aware components. When the activity enters an inactive state, the listeners are unsubscribed. Using LiveData reduces memory leaks as LiveData observers are triggered only when the activity is in an active state.
In this lesson, we’ll learn how to use LiveData through a simple example in order to understand its advantages over manual UI updates.
