What is Lifecycle-aware components in Android SDK?

Lifecycle-aware components in the Android SDK are designed to help developers manage the lifecycle of Android app components more efficiently. These components are aware of the lifecycle states, such as whether an activity is in the foreground or background, and can perform actions accordingly. This helps to minimize memory leaks and ensure that resources are used effectively, leading to better performance and user experience.

A prime example of a lifecycle-aware component is LiveData, which is an observable data holder that respects the lifecycle of its observers. It only sends updates to active observers, thus preventing updates from being sent to stopped or destroyed components.
