Annotations

OnLifecycleEvent

This annotation is deprecated.

This annotation required the usage of code generation or reflection, which should be avoided.

Interfaces

`DefaultLifecycleObserver`	Callback interface for listening to `LifecycleOwner` state changes.
`HasDefaultViewModelProviderFactory`	An interface marking a `ViewModelStoreOwner` as having a default `ViewModelProvider.Factory` for use with `ViewModelProvider`.
`LifecycleEventObserver`	Interface for receiving any `Lifecycle.Event` state changes.
`LifecycleObserver`	Marker interface that indicates a class is a `LifecycleObserver`.
`LifecycleOwner`	A class that exposes a `Lifecycle`.
`LifecycleRegistryOwner`	This interface is deprecated. Use `androidx.appcompat.app.AppCompatActivity` which extends `LifecycleOwner`, so there are no use cases for this class.
`LiveDataScope`	Interface that allows controlling a `LiveData` from a coroutine block.
`Observer`	A simple callback that can receive from `LiveData`.
`ViewModelProvider.Factory`	Implementations of the `Factory` interface are responsible for instantiating `ViewModel`s.
`ViewModelStoreOwner`	A scope that owns a `ViewModelStore`.

Classes

`AbstractSavedStateViewModelFactory`	This class is deprecated. Use `viewModelFactory` or implement `ViewModelProvider.Factory`, combined with `CreationExtras.createSavedStateHandle()`.
`AndroidViewModel`	`ViewModel` that has access to the `Application` context.
`AndroidViewModelKt`
`CoroutineLiveDataKt`
`FlowExtKt`
`FlowLiveDataConversions`
`Lifecycle`	Defines an object with a lifecycle state control flow.
`LifecycleCoroutineScope`	`CoroutineScope` tied to a `Lifecycle` and `Dispatchers.Main.immediate`.
`LifecycleKt`
`LifecycleOwnerFactory`
`LifecycleOwnerKt`
`LifecycleRegistry`	A `Lifecycle` implementation that manages multiple `LifecycleObserver`s.
`LifecycleService`	A Service that is also a `LifecycleOwner`.
`LiveData`	LiveData is a data holder class that can be observed within a given lifecycle.
`LiveDataKt`
`LiveDataReactiveStreams`
`MediatorLiveData`	`LiveData` subclass which may observe other `LiveData` objects and react on `OnChanged` events from them.
`MutableLiveData`	`LiveData` which publicly exposes `setValue` and `postValue` method.
`PausingDispatcherKt`
`ProcessLifecycleInitializer`	Initializes `ProcessLifecycleOwner` using `androidx.startup`.
`ProcessLifecycleOwner`	Class that provides lifecycle for the whole application process.
`RepeatOnLifecycleKt`
`SavedStateHandle`	A handle to saved state passed to `ViewModel`.
`SavedStateHandleSupport`
`SavedStateViewModelFactory`	A `ViewModelProvider.Factory` that creates `ViewModel`s with access to a `SavedStateHandle` in their constructor.
`ServiceLifecycleDispatcher`	Helper class to dispatch lifecycle events for a Service.
`Transformations`
`ViewModel`	Prepares and manages data for the UI.
`ViewModelKt`
`ViewModelLazy`	An implementation of `Lazy` to facilitate lazy retrieval of `ViewModel` instances.
`ViewModelProvider`	A utility class that manages the lifecycle, caching, and instantiation of `ViewModel` instances.
`ViewModelProvider.AndroidViewModelFactory`	Factory that creates `AndroidViewModel` and `ViewModel` instances.
`ViewModelProvider.NewInstanceFactory`	Factory that creates `ViewModel` instances by calling their no-argument constructor.
`ViewModelProvider.NewInstanceFactory`	Simple factory, which calls empty constructor on the give class.
`ViewModelProviderGetKt`
`ViewModelProviders`	This class is deprecated. Use the constructors for `ViewModelProvider` directly.
`ViewModelProviders.DefaultFactory`	This class is deprecated. Use ViewModelProvider.AndroidViewModelFactory
`ViewModelStore`	Stores `ViewModel` instances by key.
`ViewModelStoreOwnerDefaults`
`ViewModelStores`	This class is deprecated. Use `getViewModelStore` or `getViewModelStore` to retrieve a `ViewModelStore` directly from activities and fragments.
`ViewTreeLifecycleOwner`
`ViewTreeViewModelStoreOwner`
`WithLifecycleStateKt`
`SavedStateHandle.Companion`
`ViewModelProvider.Companion`
`ViewModelProvider.NewInstanceFactory.Companion`

Enums

`Lifecycle.Event`	Represents a transition event triggered by a change in the `LifecycleOwner`'s state.
`Lifecycle.State`	Represents the current lifecycle state of a `LifecycleOwner`.

Exceptions

LifecycleDestroyedException

A CancellationException that indicates that the Lifecycle associated with an operation reached the Lifecycle.State.DESTROYED state before the operation could complete.
