@ohos.identifier.oaid (OAID)

The OAID module provides APIs for obtaining Open Anonymous Device Identifiers (OAIDs).

NOTE - The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
- To use the APIs for obtaining OAIDs, you must request the ohos.permission.APP_TRACKING_CONSENT permission.

Modules to Import

import { identifier } from '@kit.AdsKit';

identifier.getOAID

getOAID(): Promise<string>

Obtains an OAID. This API uses a promise to return the result.

Required permissions: ohos.permission.APP_TRACKING_CONSENT

System capability: SystemCapability.Advertising.OAID

Return value

Type	Description
Promise<string>	Promise used to return the OAID. 1. If the application has configured the permission ohos.permission.APP_TRACKING_CONSENT and the permission is allowed, the OAID is returned. 2. If the application has configured the permission ohos.permission.APP_TRACKING_CONSENT and the permission is disallowed, 00000000-0000-0000-0000-000000000000 is returned. 3. If the application has not configured the permission ohos.permission.APP_TRACKING_CONSENT, 00000000-0000-0000-0000-000000000000 is returned.
