AbilityMonitor

The AbilityMonitor module provides monitors for abilities that meet specified conditions. The latest matched abilities are stored in an AbilityMonitor object.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Usage

The ability monitor is set by calling addAbilityMonitor in abilityDelegator.

import AbilityDelegatorRegistry from '@ohos.application.abilityDelegatorRegistry'
var abilityDelegator;

function onAbilityCreateCallback(data) {
    console.info("onAbilityCreateCallback");
}

var monitor = {
    abilityName: "abilityname",
    onAbilityCreate: onAbilityCreateCallback
}

abilityDelegator = AbilityDelegatorRegistry.getAbilityDelegator();
abilityDelegator.addAbilityMonitor(monitor, (err : any) => {
    console.info("addAbilityMonitor callback");
});
