@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.

Error codes

ID	Error Message
17300001	System internal error.

Example

import { identifier } from '@kit.AdsKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

try {
  identifier.getOAID().then((data) => {
    const oaid: string = data;
    hilog.info(0x0000, 'testTag', '%{public}s', `succeeded in getting oaid by promise, oaid: ${oaid}`);
  }).catch((err: BusinessError) => {
    hilog.error(0x0000, 'testTag', '%{public}s',
      `get oaid by promise failed, code: ${err.code}, message: ${err.message}`);
  })
} catch (err) {
  hilog.error(0x0000, 'testTag', '%{public}s', `get oaid by promise catch error: ${err.code} ${err.message}`);
}

identifier.getOAID

getOAID(callback: AsyncCallback<string>): void

Obtains an OAID. This API uses an asynchronous callback to return the result.

Required permissions: ohos.permission.APP_TRACKING_CONSENT

System capability: SystemCapability.Advertising.OAID

Parameters

Name	Type	Mandatory	Description

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.
