1# Device Management Changelog 2 3 4## cl.device_manager.1 Change of API Permissions 5 6Added permission verification for some APIs of device management from OpenHarmony 4.0.8.2. 7 8**Change Impact** 9 10The apps developed using OpenHarmony 4.0.8.2 or later must have the corresponding permissions. Otherwise, the related APIs cannot be called. 11 12**Key API/Component Changes** 13 14| Module| Class| Method/Attribute/Enum/Constant| Added Permission| 15| -------- | -------- | -------- | -------- | 16| \@ohos.distributedHardware.deviceManager | deviceManager | **function** release(): void | ohos.permission.ACCESS_SERVICE_DM | 17| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getTrustedDeviceListSync(): Array<DeviceInfo> | ohos.permission.ACCESS_SERVICE_DM | 18| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getTrustedDeviceList(callback:AsyncCallback<Array<DeviceInfo>>): void | ohos.permission.ACCESS_SERVICE_DM | 19| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getTrustedDeviceList(): Promise<Array<DeviceInfo>> | ohos.permission.ACCESS_SERVICE_DM | 20| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getLocalDeviceInfoSync(): DeviceInfo | ohos.permission.ACCESS_SERVICE_DM | 21| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getLocalDeviceInfo(callback:AsyncCallback<DeviceInfo>): void | ohos.permission.ACCESS_SERVICE_DM | 22| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getLocalDeviceInfo(): Promise<DeviceInfo> | ohos.permission.ACCESS_SERVICE_DM | 23| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getDeviceInfo(networkId: string, callback:AsyncCallback<DeviceInfo>): void | ohos.permission.ACCESS_SERVICE_DM | 24| \@ohos.distributedHardware.deviceManager | deviceManager | **function** getDeviceInfo(networkId: string): Promise<DeviceInfo> | ohos.permission.ACCESS_SERVICE_DM | 25| \@ohos.distributedHardware.deviceManager | deviceManager | **function** startDeviceDiscovery(subscribeInfo: SubscribeInfo): void | ohos.permission.ACCESS_SERVICE_DM | 26| \@ohos.distributedHardware.deviceManager | deviceManager | **function** startDeviceDiscovery(subscribeInfo: SubscribeInfo, filterOptions?: string): void | ohos.permission.ACCESS_SERVICE_DM | 27| \@ohos.distributedHardware.deviceManager | deviceManager | **function** stopDeviceDiscovery(subscribeId: number): void | ohos.permission.ACCESS_SERVICE_DM | 28| \@ohos.distributedHardware.deviceManager | deviceManager | **function** publishDeviceDiscovery(publishInfo: PublishInfo): void | ohos.permission.ACCESS_SERVICE_DM | 29| \@ohos.distributedHardware.deviceManager | deviceManager | **function** unPublishDeviceDiscovery(publishId: number): void | ohos.permission.ACCESS_SERVICE_DM | 30| \@ohos.distributedHardware.deviceManager | deviceManager | **function** authenticateDevice(deviceInfo: DeviceInfo, authParam: AuthParam, callback: AsyncCallback<{deviceId: string, pinToken ?: number}>): void | ohos.permission.ACCESS_SERVICE_DM | 31| \@ohos.distributedHardware.deviceManager | deviceManager | **function** unAuthenticateDevice(deviceInfo: DeviceInfo): void | ohos.permission.ACCESS_SERVICE_DM | 32| \@ohos.distributedHardware.deviceManager | deviceManager | **function** verifyAuthInfo(authInfo: AuthInfo, callback: AsyncCallback<{deviceId: string, level: number}>): void | ohos.permission.ACCESS_SERVICE_DM | 33| \@ohos.distributedHardware.deviceManager | deviceManager | **function** setUserOperation(operateAction: number, params: string): void | ohos.permission.ACCESS_SERVICE_DM | 34| \@ohos.distributedHardware.deviceManager | deviceManager | **function** requestCredentialRegisterInfo(requestInfo: string, callback: AsyncCallback<{registerInfo: string}>): void;
