# AbilityFirstFrameStateData (System API)

**AbilityFirstFrameStateData** defines the data reported by the callback when the first frame of an ability is rendered. Specifically, the data is returned in the **onAbilityFirstFrameDrawn** callback of [AbilityFirstFrameStateObserver](js-apis-inner-application-abilityFirstFrameStateObserver-sys.md) after the first frame rendering completion event is listened for by calling [on](js-apis-app-ability-appManager-sys.md#appmanageronabilityfirstframestate12).
