AnimationBackendDelegateWithInactivityCheck

extends AnimationBackendDelegate<T extends AnimationBackend>

| java.lang.Object | | ↳ | com.facebook.fresco.animation.backend.AnimationBackendDelegate<T extends com.facebook.fresco.animation.backend.AnimationBackend> | | | ↳ | com.facebook.fresco.animation.backend.AnimationBackendDelegateWithInactivityCheck<T extends com.facebook.fresco.animation.backend.AnimationBackend> |

Class Overview

Animation backend delegate for animation backends that implement AnimationBackendDelegateWithInactivityCheck.InactivityListener. After a certain inactivity period (default = #INACTIVITY_THRESHOLD_MS, onInactive() will be called.

This can for example be used to drop caches if needed.

New instances can be created with createForBackend(AnimationBackend, MonotonicClock, ScheduledExecutorService).
