AbilityDelegator

更新时间: 2023-02-17 09:19

AbilityDelegator提供添加用于监视指定ability的生命周期状态更改的AbilityMonitor对象的能力，包括对AbilityMonitor实例的添加、删除、等待ability到达OnCreate生命周期、设置等待时间等、获取指定ability的生命周期状态、获取当前应用顶部ability、启动指定ability等。

说明

本模块首批接口从API version 8开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。

使用说明

通过AbilityDelegatorRegistry中getAbilityDelegator方法获取。

import AbilityDelegatorRegistry from '@ohos.application.abilityDelegatorRegistry'

var abilityDelegator;

abilityDelegator = AbilityDelegatorRegistry.getAbilityDelegator();
