## cl.ability.1 Auto Startup Related APIs in ApplicationContext Are Deleted

**Access Level**

Public API

**Reason for Change**

According to security and privacy requirements, APIs related to auto startup in **ApplicationContext** are deleted. Applications cannot proactively set the auto startup status.

**Change Impact**

This change is a non-compatible change. If your code uses the involved APIs, delete them.

**API Level**

**Change Since**

OpenHarmony SDK 4.1.6.5

**Reason for Change**

After the APIs related to auto startup in **ApplicationContext** are deleted, **AutoStartupInfo** is not available for third-party applications and is changed to a system API.

**Change Impact**

This change is a non-compatible change. If your code uses the involved APIs, delete them.

Make sure the APIs are only invoked by system applications.

The code snippet is as follows:

```ts
import AutoStartupManager from '@ohos.app.ability.autoStartupManager';
import { BusinessError } from '@ohos.base';

try {
  AutoStartupManager.setApplicationAutoStartup({
    bundleName: 'com.example.autostartupapp',
    abilityName: 'EntryAbility'
  }).then((data: void) => {
    console.info('====> setApplicationAutoStartup data: ' + JSON.stringify(data));
  }).catch((err: BusinessError) => {
    console.info('====> setApplicationAutoStartup err: ' + JSON.stringify(err));
  });
} catch (err) {
  console.info('====> setApplicationAutoStartup throw err: ' + JSON.stringify(err));
}
```
