# ApplicationInfo

The **ApplicationInfo** module defines the application information. A system application can obtain its own or others' application information through [bundleManager.getApplicationInfo](js-apis-bundleManager.md#bundlemanagergetapplicationinfo). The input parameter [appFlags](js-apis-bundleManager.md#applicationflag) specifies the information to be contained in the returned [ApplicationInfo](js-apis-bundleManager-applicationInfo.md) 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.
