@ohos.enterprise.deviceInfo (Device Information Management)

The deviceInfo module provides APIs for enterprise device information management, including the API for obtaining device serial numbers.

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.

The APIs of this module can be used only in the stage model.

The APIs provided by this module can be called only by a device administrator application that is enabled.

Modules to Import

import deviceInfo from '@ohos.enterprise.deviceInfo';

deviceInfo.getDeviceSerial

getDeviceSerial(admin: Want, callback: AsyncCallback<string>): void

Obtains the device serial number through the specified device administrator application. This API uses an asynchronous callback to return the result.

Required permissions: ohos.permission.ENTERPRISE_GET_DEVICE_INFO

System capability: SystemCapability.Customization.EnterpriseDeviceManager

System API: This is a system API.

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	Device administrator application.
callback	AsyncCallback<string>	Yes	Callback invoked to return the result. If the operation is successful, err is null and data is the device serial number obtained. If the operation fails, err is an error object.

Error codes

For details about the error codes, see Enterprise Device Management Error Codes.

ID	Error Message
9200001	the application is not an administrator of the device.
9200002	the administrator application does not have permission to manage the device.

Example

import Want from '@ohos.app.ability.Want';
let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};

deviceInfo.getDeviceSerial(wantTemp, (err, result) => {
  if (err) {
    console.error(`Failed to get device serial. Code: ${err.code}, message: ${err.message}`);
    return;
  }
  console.info(`Succeeded in getting device serial, result : ${result}`);
});

deviceInfo.getDeviceSerial

getDeviceSerial(admin: Want): Promise<string>

Obtains the device serial number through the specified device administrator application. This API uses a promise to return the result.

Required permissions: ohos.permission.ENTERPRISE_GET_DEVICE_INFO

System capability: SystemCapability.Customization.EnterpriseDeviceManager

System API: This is a system API.

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	Device administrator application.

Return value

Type	Description
Promise<string>	Promise used to return the device serial number.

Error codes

ID	Error Message
9200001	the application is not an administrator of the device.
9200002	the administrator application does not have permission to manage the device.

Example

import Want from '@ohos.app.ability.Want';
import { BusinessError } from '@ohos.base';
let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};

deviceInfo.getDeviceSerial(wantTemp).then((result) => {
  console.info(`Succeeded in getting device serial, result : ${result}`);
}).catch((err: BusinessError) => {
  console.error(`Failed to get device serial. Code: ${err.code}, message: ${err.message}`);
});

deviceInfo.getDisplayVersion

getDisplayVersion(admin: Want, callback: AsyncCallback<string>): void;
