# @ohos.app.ability.autoStartupManager (autoStartupManager) (System API)

The **autoStartupManager** module provides APIs for listening for auto-startup status changes of application components and setting application components to automatically start upon system boot.

> **NOTE**
>
> The initial APIs of this module are supported since API version 11. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs of this module can be used only in the stage model.
>
> The APIs provided by this module are system APIs.

## Modules to Import

```ts
import { autoStartupManager } from '@kit.AbilityKit';
```

## on

on(type: 'systemAutoStartup', callback: AutoStartupCallback): void
