Interfaces

DefaultLifecycleObserver	Callback interface for listening to `LifecycleOwner` state changes.
HasDefaultViewModelProviderFactory	Interface that marks a `ViewModelStoreOwner` as having a default `ViewModelProvider.Factory` for use with `ViewModelProvider.ViewModelProvider(ViewModelStoreOwner)`.
LifecycleEventObserver	Class that can receive any lifecycle change and dispatch it to the receiver.
LifecycleObserver	Marks a class as a LifecycleObserver.

ViewModelProvider.Factory	Implementations of `Factory` interface are responsible to instantiate ViewModels.
ViewModelStoreOwner	A scope that owns `ViewModelStore`.

Lifecycle	Defines an object that has an Android Lifecycle.
LifecycleRegistry	An implementation of `Lifecycle` that can handle multiple observers.
LifecycleService	A Service that is also a `LifecycleOwner`.

MutableLiveData<T>	`LiveData` which publicly exposes `setValue(T)` and `postValue(T)` method.
ProcessLifecycleOwner	Class that provides lifecycle for the whole application process.
SavedStateHandle	A handle to saved state passed down to `ViewModel`.
SavedStateViewModelFactory	`ViewModelProvider.Factory` that can create ViewModels accessing and contributing to a saved state via `SavedStateHandle` received in a constructor.
ServiceLifecycleDispatcher	Helper class to dispatch lifecycle events for a service.
Transformations	Transformation methods for `LiveData`.
ViewModel	ViewModel is a class that is responsible for preparing and managing the data for an `Activity` or a `Fragment`.
ViewModelProvider	An utility class that provides `ViewModels` for a scope.

ViewModelProviders.DefaultFactory	This class is deprecated. Use `ViewModelProvider.AndroidViewModelFactory`
ViewModelStore	Class to store `ViewModels`.
ViewModelStores	This class is deprecated. Use `ComponentActivity.getViewModelStore()` or `Fragment.getViewModelStore()` to retrieve a `ViewModelStore` directly from activities and fragments.
ViewTreeLifecycleOwner	Accessors for finding a view tree-local `LifecycleOwner` that reports the lifecycle for the given view.
ViewTreeViewModelStoreOwner	Accessors for finding a view tree-local `ViewModelStoreOwner` that allows access to a `ViewModelStore` for the given view.
