# @ohos.app.ability.wantAgent (WantAgent模块)

app.ability.WantAgent模块提供了创建WantAgent实例、获取实例的用户ID、获取want信息、比较WantAgent实例和获取bundle名称等能力。该模块将会取代[@ohos.wantAgent](js-apis-wantAgent.md)模块，建议优先使用本模块。

> **说明：**
> 
> 本模块首批接口从API version 9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。  

## 导入模块

```ts
import WantAgent from '@ohos.app.ability.wantAgent';
```
