An application can obtain its own application information through [bundleManager.getBundleInfoForSelf](js-apis-bundleManager.md#bundlemanagergetbundleinfoforself), with **GET_BUNDLE_INFO_WITH_APPLICATION** passed in to [bundleFlags](js-apis-bundleManager.md#bundleflag). 10 11> **NOTE** 12> 13> 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. 14 15## Modules to Import 16 17```ts 18import { bundleManager } from '@kit.AbilityKit'; 19``` 20 21## ApplicationInfo 22 23**System capability**: SystemCapability.BundleManager.BundleFramework.Core 24 25| Name | Type | Read-Only| Optional| Description | 26| -------------------------- | ------------------------------------------------------------ | ---- | ---- | ------------------------------------------------------------ | 27| name | string | Yes | No | Application name.<br>**Atomic service API**: This API can be used in atomic services since API version 11. | 28| description | string | Yes | No | Description of the application.
