ProcessLifecycleOwner
open class ProcessLifecycleOwner : LifecycleOwner
kotlin.Any | |
↳ | androidx.lifecycle.ProcessLifecycleOwner |
Class that provides lifecycle for the whole application process.
You can consider this LifecycleOwner as the composite of all of your Activities, except that Lifecycle.Event#ON_CREATE
will be dispatched once and Lifecycle.Event#ON_DESTROY
will never be dispatched. Other lifecycle events will be dispatched with following rules: ProcessLifecycleOwner will dispatch Lifecycle.Event#ON_START
, Lifecycle.Event#ON_RESUME
events, as a first activity moves through these events. Lifecycle.Event#ON_PAUSE
, Lifecycle.Event#ON_STOP
, events will be dispatched with a delay after a last activity passed through them. This delay is long enough to guarantee that ProcessLifecycleOwner won't send any events if activities are destroyed and recreated due to a configuration change.
It is useful for use cases where you would like to react on your app coming to the foreground or going to the background and you don't need a milliseconds accuracy in receiving lifecycle events.
