Android Jetpack: LiveData

From the creator

LiveData is part of the Lifecycle library which was designed to help you solve common Android Lifecycle challenges and to make your apps more maintainable and testable. LiveData is a lifecycle-aware observable. LiveData makes it easy to keep what's showing on screen in sync with the data. Benefits include: * Lifecycle awareness: LiveData works well with the android lifecycle by only sending updates to UI components that are on screen and automatically removing listeners when a UI component is destroyed. * Can be returned by Room, to learn more about Room → https://goo.gl/hWAq6R * Reactive UIs with ViewModel and Data Binding * Includes basic transformations map and switchMap and MediatorLiveData LiveData is usually created in a ViewModel class → https://goo.gl/f3gTQx] The Lifecycle library includes other classes that LiveData works with, including Lifecycle, LifecycleOwner and LifecycleObservable.
