@ohos.distributedHardware.deviceManager (设备管理)(系统接口)

本模块能力已更新至新模块。建议使用新模块的接口进行开发，参见@ohos.distributedDeviceManager。

本模块提供分布式设备管理能力。

系统应用可调用接口实现如下功能：

• 注册和解除注册设备上下线变化监听
• 发现周边不可信设备
• 认证和取消认证设备
• 查询可信设备列表
• 查询本地设备信息，包括设备名称，设备类型和设备标识
• 发布设备发现

说明：

• 本模块首批接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
• 本模块为系统接口，三方应用不支持调用。
