-# 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**.
-
-```js
-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");
-});
