图7示出了本申请实施例提供的电子设备的另一软件架构图。下面结合图7介绍本申请实施例中本机和其他设备之间的认证流程、服务请求流程、服务数据同步流程以及设备检测流程。
认证流程
当电子设备检测到用户点击某个分布式应用，如相册、音乐播放器、文件管理或者联系人等等应用时，电子设备可以自动触发对周围设备的认证流程。
示例性的，电子设备检测到用户在电子设备的桌面点击某个分布式应用的图标后，电子设备打开该应用，显示该应用的界面。具体的，当电子设备检测到用户在电子设备的桌面点击某个应用的图标(例如，相册、音乐播放器、文件管理或者联系人)后，如果该应用分布式应用，那么分布式应用层的该应用程序会向服务层的设备监视器发送该应用对应的标号(例如，进程识别号(process identifier，PID))和该应用对应的进程名称，设备监视器可以通过该标号和进程名称确定是哪个App启动了。例如，电子设备通过确定该相册的进程识别号和进程名称确定相册应用启动了。设备监视器可以通过本机在线广播模块生成蓝牙低功耗(Bluetooth low energy，BLE)广播数据包，该广播数据包中可以携带本机的设备名称和地址(例如，MAC地址、IP地址等)。设备监视器可以通过通信协议层的蓝牙广播/扫描模块将该BLE广播数据包广播出去。电子设备还可以通过蓝牙广播/扫描 模块实时接收周围其他设备发送的BLE广播响应，BLE广播响应中可以携带其他设备的设备名称信息。设备监视器在接收到广播响应后，可以通过其他设备的名称信息确定其是否为同一账号下的设备，或者是否为同一家庭群组中其他账号下的设备。如果是同一账号下的其他设备，则本机可以和其他设备直接通过认证；或者如果是家庭群组中其他账号下的其他设备，则本机也可以和其他设备直接通过认证。分布式应用可以对设备知识库进行监听，当分布式应用发现设备知识库中增加了其他设备的信息后，可以通过显示界面显示相应的信息。
示例性的，如图3中的(c)所示，当手机确定周围有同一账号下的其他设备后，就可以通过显示界面自从显示出“其他设备”。
设备监视器还可以将其他设备的设备名称、设备类型、设备状态信息、能力信息以及地址信息等保存在设备知识库中。
本申请实施例中，若设备监视器确定广播响应中携带的设备名称不是同一账号下的其他设备，或者也不是同一家庭群组中其他账号下的设备，那么设备监视器还可以向应用层的分布式响应发送该设备名称的信息，并由分布式应用提示用户该设备不是同一账号下的其他设备，或者不是同一家庭群组中其他账号下的设备。分布式应用可以提示用户通过扫描二维码的方式对该设备进行认证。具体通过二维码认证的过程可以参考上述实施例中的描述，为了简洁，在此不再赘述。一个实施例中，用户也可以将二维码截屏发送给远场的设备，远场的设备通过扫描二维码和当前设备建立网络连接，从而可以远场的设备将数字资产的信息同步到当前设备。
一个实施例中，电子设备除了通过短距离通信发现周围的设备外，也可以通过远场通信技术发现其他设备。例如，电子设备可以通过服务器、蜂窝网络等远场通信技术和远场设备建立网络连接。
服务请求流程
在电子设备和其他设备认证通过后，分布式应用可以调用应用层的分布式服务请求生成相应的服务请求。
示例性的，电子设备检测到用户打开相册应用时，相册应用可以调用分布式服务请求生成缩略图请求。分布式服务请求可以将该缩略图请求发送给服务层的服务处理引擎(service process engine，SPE)。
本申请实施例中，SPE为逻辑处理单元，可以用于执行服务代理功能，对服务请求进行分析处理，为应用选择合适的设备/硬件/服务。SPE在接收到相应的服务请求后，可以会通过设备知识库为该服务请求选择合适的设备。示例性的，设备知识库中保存有设备A、设备B和设备C的信息。SPE可以先获取设备A、设备B和设备C的状态信息，如果SPE发现设备A处于离线状态，而设备B和设备C处于在线状态，那么SPE可以确定设备B和设备C为合适的设备。
SPE可以将该服务请求以及其他设备(设备B和设备C)的地址信息转发给数据总线(DataBus)。并由数据总线下发给通信协议层的通信层下行模块。通信层下行模块可以根据其他设备的地址信息将该服务请求转发给其他设备。
相应的，其他设备在接收到该服务请求后会对该服务请求进行解析并将请求发送给其他设备中的SPE。其他设备的SPE代理本地服务，并向电子设备返回服务响应以及相应的 数据。从而完成服务请求过程。
电子设备在获取到其他设备发送的响应和数据后，可以将数据保存在服务层的数据存储区，同时还可以向应用层的分布式应用发送相应的数据，从而用户可以通过显示界面看到其他设备上的数据。
示例性的，如图3中的(d)所示，当手机检测到用户点击“其他设备”时，可以触发上述服务请求流程，手机备可以向其他设备(华为M7，荣耀智慧屏以及华为P30)请求图片元数据。电子设备在接收到其他设备发送的元数据后，可以通过显示界面显示其他设备上相册中照片的数量。
示例性的，如图3中的(g)所示，当手机检测到用户点击照片311缩略图的操作后，可以触发上述服务请求流程，手机可以向华为M7请求预设屏幕分辨率的照片311的数据。
示例性的，如图3中的(g)所示，当手机检测到用户点击保存至本地的操作后，可以触发上述服务请求流程，手机可以向华为M7请求照片311的原始数据。
服务数据同步流程
在电子设备和其他设备相互共享数据之前，电子设备需要首先和其他设备建立数据传输的通道(DataBus PIPE)。其他设备在接收到电子设备发送的服务请求后，可以根据服务请求调用DataBus PIPE建立接口，从而建立数据传输的通道。在数据传输的通道建立好之后，其他设备可以将自己保存的数据共享给电子设备。
本申请实施例中，第一电子设备和第二电子设备之间的数据同步流程可以包括首次同步和增量同步，首次同步是指在第一电子设备和第二电子设备第一次建立数据传输的通道时触发的同步，第一电子设备将自己的数据同步到第二电子设备，或者，第二电子设备将自己的数据同步到第一电子设备；增量同步是指当第一电子设备和第二电子设备上的数据发生变化时触发的同步。例如，当第一电子设备上的数据发生变化(例如，第一电子设备上增加了一些照片或者视频)，那么第一电子设备可以将自己的数据同步到第二电子设备上。
应理解，在第一电子设备和第二电子设备的网络连接未断开，或者设备间连接未断开时，第一电子设备和第二电子设备之间的数据传输的通道可以是一直存在的。当有数据需要同步时，可以直接通过数据传输通道进行数据同步。
设备检测
电子设备在认证过程中需要对周围其他设备发送的信息进行扫描，从而确定周围合适的设备。但是有些设备可能一段时间后就离线，所以这就需要电子设备对其他设备进行检测。
示例性的，电子设备可以周期性的发送BLE广播数据包，如果在电子设备在发送完BLE广播数据包后的预设时长内接收到其他设备的广播响应，则可以确定其他设备处于在线状态；相反，如果电子设备在预设时长内没有接收到广播响应，则可以确定其他设备已经离线。
一个实施例中，电子设备在初始扫描时没有发现设备B(设备B和电子设备为同一账号下的设备)，后续在扫描的过程又发现了设备B。那么电子设备可以将设备B的信息保存在设备知识库中。同时，设备监视器还可以向分布式应用发送设备更新后的信息，从而通过电子设备的显示界面显示设备B的信息。
分布式应用可以监听设备知识库的信息。当设备知识库中的设备信息发生变化时，分布式应用会通过显示界面实时更新设备信息。同时，SPE在向DataBus发送服务请求时，也可以根据更新后的设备信息向DataBus发送更新后的设备的地址。
下面结合图8介绍本申请实施提供的设备A和设备B之间数据共享的过程。该过程包括：
101，当电子设备在分布式应用的显示界面上检测到用户的操作时，分布式应用通过调用业务的分布式服务的软件开发包(software development kit，SDK)发起服务请求。SDK会向服务层的SPE发送服务请求。具体服务请求的内容可以根据用户的操作而定。
例如，如图3中的(c)，当电子设备检测到用户点击“其他设备”的操作后，SDK会向SPE发送图片元数据以及缩略图的服务请求。
又例如，如图3中的(f)，当手机在显示屏上检测到用户向上滑动的操作后，手机可以向下展示更多的照片缩略图。手机之前向华为M7请求图片元数据以及缩略图时可能只请求到了200张照片缩略图。在手机向下滚动照片缩略图的过程中，当手机确定即将滚动到第200张照片缩略图时，SDK可以自动向华为M7再一次发起照片缩略图的服务请求。从而可以保证用户观看照片缩略图时的连续性。
又例如，如图3中的(f)，当手机在显示屏上检测到用户点击照片311的操作后，手机可以向华为M7请求预设屏幕分辨率(例如，1080×1920像素值的图片)的照片311的数据。
又例如，如图3中的(g)，当手机检测到用户点击保存至本地的操作后，手机可以向华为M7请求照片311的原始数据。
102，SPE将服务请求以及设备B的地址通过数据总线转发给通信协议层。
103，通信协议层根据设备B的地址向设备B发送服务请求。
104，设备B的通信协议层下接收到服务请求后，将该服务请求转发给设备B的SPE。
105，设备B的SPE将服务请求继续转发给检索服务。
106，检索服务在获取到服务请求后，可以对该服务请求进行解析，进而从设备B的数据索引存储区查找相应的数据索引。
示例性的，设备B的检索服务在确定该服务请求是用来请求图片元数据以及缩略图后，可以向数据索引存储区查找相应的设备B中保存的照片的索引。这里的照片索引可以是设备B对设备B中保存的照片进行分类后建立的索引。示例性的，设备B可以将设备B中保存的照片按照时间、任务、地点以及标签等等信息进行分类。设备B中保存的照片的索引也可以指每一张照片的分类信息。
107，检索服务根据服务请求，查找设备B中数据存储区的数据。
示例性的，设备B的检索服务在确定该服务请求是用来请求图片元数据以及缩略图后，可以向数据存储区查找设备B中保存的图片元数据以及缩略图的信息。设备B的数据存储区可以包括本地数据以及远端设备A的数据。设备B在查找时可以对本地数据进行查找，从而获取到相应的数据。
示例性的，表1示出了一种图片元数据。
表1

Figure PCTCN2021081024-appb-000004
应理解，以上表1所述的图片元数据仅仅是示意性的，本申请实施例对此并不作任何限定。
还应理解，图片元数据可以是通过电子设备的存储器中保存的图片的原始数据得到的。内部存储器与图8中的数据存储区并不相同，内部存储器中保存的是图片的原始数据，原始数据的数据量是很大的；而数据存储区中保存的图片元数据以及缩略图通过图片的原始数据得到，元数据以及缩略图的数据量是很小的。
如图3中的(c)，SDK会向SPE发送图片元数据以及缩略图的服务请求过程中，华为M7向手机同步的数据其实是图片元数据以及缩略图。
如图3中的(f)，当手机在显示屏上检测到用户向上滑动的操作后，手机在即将展示完之前保存的缩略图时，可以再一次向华为M7请求更多的缩略图。
如图3中的(g)，当手机检测到用户点击保存至本地的操作后，手机可以向华为M7请求照片311的原始数据。
本申请实施例中，在当前设备进行其他设备的数字资产访问和管理时，并不是直接将其他设备的原始数据拷贝到当前设备本地，这样有助于提升用户的浏览速度并且可以节省电子设备的存储空间。
108，设备B的检索服务向设备B的通信协议层转发对服务请求的响应以及查找到的数据。
109，设备B的通信协议层将设备A的通信协议层发送响应以及数据。
示例性的，以图片为例，设备B可以向设备A发送设备B保存的图片元数据以及缩略图。例如，如果设备B中保存了1000张图片，那么设备B可以向设备A发送这1000张图片的元数据信息以及200张图片的缩略图信息。
110，设备A的通信协议层将收到的响应以及数据发送给设备A的检索服务。
111，设备A的检索服务将接收到数据存储在设备A的数据存储区。
如图8所示，设备A的数据存储区包括设备A的本地数据以及远端设备B的数据。设备A在接收到设备B发送的数据后，可以将其存储在远端设备B数据中。
一个实施例中，设备A在接收到设备B发送的元数据后，可以根据元数据中的信息 对数据建立索引，并将设备B元数据的索引保存在设备A的数据索引存储区。
示例性的，以图片为例，设备B中保存有1000张图片，那么设备B可以向设备A发送的这1000张图片的元数据，元数据中包括了图片创建的时间、创建的地点以及图片的分类标签等等，元数据的结构可以如表2所示。

应理解，上述表2和表3所示的分类方式仅仅是示意性的，本申请实施例中还可以根据其他分类方式对接收到的元数据建立索引。例如，对于地点的分类可以还包括分类3，分类3中可以包括每个城市的区域信息，例如，南京市还可以进一步分为南京市花都区、南京市雨花台区等、西安市还可以进一步分为西安市碑林区、西安市雁塔区等。
本申请实施例中，当前设备可以接收到其他设备发送的元数据，并根据这些元数据中的信息建立相应的索引，这样方便用户在当前设备上搜索本地保存和另一设备上保存的数据时，快速地向用户展示搜索结果。
示例性的，如图5中的(c)所示，当用户在搜索框中输入关键词“花”后，手机可以显示根据关键词“花”得到的分类结果。在对“花”的搜索结果中包括根据地点进行分类得到的“花都区”和“雨花台区”，根据拍摄人物的名字进行分类得到的“小花姐”和“花花”。
示例性的，如图5中的(d)所示，当用户在搜索框中输入关键词“花朵”后，手机可以显示根据关键词“花朵”得到的分类结果。其中，手机可以显示在2018年拍摄的关于“花朵”的照片有8张(还可以显示2019年、2020年拍摄的关于“花朵”的照片，图中未示出)，还可以显示本机找到的关于“花朵”的照片数量以及其他设备中找到的关于“花朵”的照片数据。
112，设备A的检索服务向应用层的SDK发送数据。并由设备A的用户界面呈现给用户。
示例性的，如图3中的(d)所示，检索服务可以向SDK发送华为M7、荣耀智慧屏以及华为P30中图片的数量信息。手机也可以通经过显示界面显示每台设备中的图片的数量。
本申请中，当前设备可以在数据存储区保存其他设备发送的元数据信息，例如，华为M7可以向手机发送华为M7保存的80张图片对应的80个元数据信息，那么检索服务可以对接收到的元数据的个数进行统计，元数据的个数统计结果也就是华为M7上保存的图片的个数。
示例性的，如图3中的(e)所示，当手机检测到用户点击文件夹305的操作后，检索服务可以向SDK发送华为M7中文件夹305中缩略图的信息，并由显示屏显示如图3中的(f)所示的GUI。
201，当设备B中保存的数据发生变化时，设备B的应用会调用SDK向检索服务指示共享数据发生变化。
例如，用户使用设备B又拍摄了多张照片后，可以触发SDK向检索服务指示相册应用中照片的数据发生变化。
202，检索服务在设备B数据索引存储区中建立新的共享数据索引。
示例性的，设备B根据新增加的照片的标签信息更新设备B数据索引存储区中保存的索引信息。
203，检索服务更新设备B数据存储区中的信息。
示例性的，设备B根据新增加的照片，在设备B数据存储区中增加其对应的元数据以及缩略图的信息。
此后，设备B可以通过通信协议层将更新后的数据信息发送给设备A的通信协议层。 并由设备A的检索服务对设备A数据存储区中的远端设备B数据进行更新。在更新完成后，检索服务还可以向应用层的SDK指示其更新后的数据，并由设备A的用户界面向用户呈现设备B中更新后的数据。
图9示出了本申请实施例提供的针对图片、视频分布式浏览、搜索和管理的示意图。
如图9所示，设备A、设备B和设备C的内部存储器中保存有各自的图片、视频的原始数据。设备A、设备B和设备C可以分别根据内部存储器中保存的原始数据确定服务层数据存储区中的元数据、数据索引以及缩略图的信息。
示例性的，用户使用手机在南京市花都区拍摄了一张照片后，该照片的原始数据大小为8Mb，那么手机可以将这张照片的原始数据保存在内部存储区中。同时，手机还可以将拍摄这张照片的设备的设备名称(例如，华为M7)、文件名(例如，图片的后缀.JPG)、文件的绝对路径(例如，该照片在内部存储区中的物理路径)、文件大小(例如，该照片的大小为8Mb)、文件添加到设备中的时间(例如，2019年2月14日上午10:00)、文件宽度(例如，500像素)、文件高度(例如，500像素)以及文件类型(例如，图片)保存在数据存储区中。手机可以将该照片的索引存储在数据索引存储区中，例如，手机可以自动识别照片上的信息，并根据照片上的信息对照片进行分类(或者，为照片打上相应的标签)。当照片的元数据从华为M7同步到当前设备时，当前设备可以根据该索引对图片中各类型数据(例如，时间、地点、标签信息)构建索引(如使用lucence)，便于后续的搜索。手机可以将该照片对应的缩略图存储在缩略图数据库中。
应理解，图9中的数据存储区、缩略图数据库可以位于图8中所示的数据存储区；图9中的数据索引存储区为图9中的数据索引存储区。
一个实施例中，图9所示的数据存储区、数据索引存储区以及缩略图数据库还可以按照{Group ID、App ID}这两个维度进行隔离，并且手机可以控制相应的访问权限。

(4)信号与干扰加噪比(signal to interference plus noise ratio，SINR)。
应理解，以上仅仅是以第二电子设备根据信号强度或者信号质量来确定第二电子设备和第一电子设备之间的距离，还可以是通过其他方式来确定，本申请实施例中对此并不作限定。
可选地，第一电子设备上登录的账号和第二电子设备上登录的账号相关联包括：第一 电子设备上登录的账号和第二电子设备上登录的账号相同；或者，第一电子设备上登录的账号和第二电子设备上登录的账号位于同一家庭群组中；或者，第一电子设备上登录的账号为第二电子设备上登录的账号授权过的账号。
示例性的，第二电子设备中可以保存有第二电子设备上登录的账号下其他电子设备的设备名称的信息，那么第二电子设备可以根据响应消息中的设备名称来判断第一电子设备是同一账号下的设备。
示例性的，第二电子设备中还可以保存有与第二电子设备上登录的账号位于同一家庭群组中的其他账号下的设备的设备名称，那么第二电子设备可以根据响应消息中的设备名称来判断第一电子设备是同一账号下的设备，或者是家庭群组中其他账号下的设备。
本申请实施例中，若第一电子设备和第二电子设备是同一账号下的设备，或者，是家庭群组中不同账号下的设备，那么第一电子设备和第二电子设备可以通过信任环直接相互信任。
S1106，第二电子设备向第一电子设备发送请求消息，该请求消息用于请求第一应用程序下一个或者多个文件的元数据。
一个实施例中，第二电子设备在确定在第一电子设备为预设距离内且和其登录的账号和第二电子设备登录的账号相关联后，就可以向第一电子设备发送请求消息。
一个实施例中，第二电子设备也可以在检测到用户打开第一应用程序时，向第一电子设备发送请求消息。
一个实施例中，第二电子设备还可以向第二电子设备发送多个请求消息，每个请求消息用于请求不同应用程序下的元数据。
S1107，第一电子设备向第二电子设备发送该第一应用程序下一个或者多个文件的元数据。
示例性的，第二电子设备可以将第一电子设备发送的一个或者多个文件的元数据存储在第二电子设备的数据存储区(如图8中的设备A的数据存储区的本地数据中)。
本申请实施例中，第二电子设备可以确定预设距离内和第二电子设备上登录的账号相关联的第一电子设备，第二电子设备可以向第一电子设备请求此应用下文件的元数据，方便用户通过第二电子设备快速查看第一电子设备上保存的数字资产的情况，满足了用户对于散落在各个设备上的数字资产统一管理的诉求，从而有助于提升用户的体验。
同时，第一电子设备向第二电子设备共享的其实并不是每个文件的原始数据，而是每个文件对应的元数据，那么在数据共享过程中也可以使得用户快速浏览其他设备上的数字资产情况，也更加节省电子设备的存储空间。
一个实施例中，第二电子设备可以根据接收到的第一电子设备发送的一个或者多个文件的元数据，生成相应的元数据索引并保存在第二电子设备的数据索引存储区(如图8中设备A的数据索引存储区的远端设备B数据索引中)。
本申请实施例中，第二电子设备在获取到第一电子设备保存的每个文件的元数据后，可以根据元数据建立每个文件的索引；并且第二电子设备也可以建立本地保存的每个文件的元数据的索引。这样方便用户之后在搜索想到查看的文件时，快速找到想要查看的文件，从而有助于提升用户体验。
可选地，若该第一应用程序为相册应用，那么第一电子设备除了向第二电子设备发送 该一张或者多张图片的元数据以外，还可以向第二电子设备发送一张或多张图片中至少部分图片的缩略图。例如，第一电子设备中保存了1000张图片，那么第一电子设备还可以在响应消息中携带其中的200张图片的缩略图。
本申请实施例中，对于相册应用，第二电子设备还可以向第一电子设备请求第一电子设备中的相册应用中一张或者多张图片的缩略图，这样方便用户在点击文件夹后，第二电子设备及时向用户展示一张或者多张图片的缩略图中的至少部分。
如图3中的(f)，当手机检测到用户向上滑动的操作后，可以滚动显示缩略图。当用户即将查看到第200张缩略图(例如，查看到第150张缩略图)时，可以触发手机再一次向华为M7请求更多的缩略图，从而保证用户在查看缩略图的过程中不会有卡顿的现象。
S1108，第二电子设备通过显示屏显示文件夹，第二电子设备的设备名以及文件数量。
示例性的，如图3中的(d)所示，手机可以在界面上显示文件夹304，设备名称为“华为M7”以及文件数量“80”。
应理解，手机在S1107中可以从华为M7接收到80个元数据，那么手机在界面上显示“80”表示手机确定华为M7上保存有80张图片。
若手机检测到用户点击文件夹304的操作，那么手机可以显示如图3中的(e)或者显示如图3中的(f)。若直接显示如图3中的(f)，那么手机可以在界面上显示多张缩略图，由于S1107中华为M7也可以向手机发送多张缩略图，那么手机的界面其实可以直接从图3中的(d)跳转至图3中的(f)，用户不会有卡顿的现象。
可选地，当第二电子设备检测到用户点击某一张缩略图的操作后，第二电子设备可以向第一电子设备请求预设屏幕分辨率的图片。
如图3中的(f)所示，当手机检测到用户点击缩略图311的操作后，手机可以显示如图3中的(g)所示的图片，这张图片其实并不是原始的图片，相比于原始的图片，预设屏幕分辨率的图片的所占的存储空间更小，这样可以使得较快用户浏览的速度。图3中的(g)所示的GUI上还可以包括图片的拍摄时间、拍摄地点等信息，这样方便用户进一步了解图片的详细情况。
例如，缩略图所占的空间大概在20KB左右，预设屏幕分辨率的图片所占的空间大概在200KB左右，而图片原始数据所占空间大概在5MB-20MB。
如图3中的(f)所示，当手机检测到用户点击保存至本地的操作后，手机可以向华为M7请求图片的原始数据，并将华为M7发送的原始数据保存在本地。
本申请实施例中，当用户希望将第一电子设备上的某张照片保存在第二电子设备本地时，第二电子设备才会向第一电子设备请求该图片的原始数据。这样第二电子设备在向用户展示第一电子设备图片的过程中并不需要第二电子设备存储第一电子设备上保存的每张照片的原始数据，使得用户快速浏览其他设备上的数字资产情况，也更加节省电子设备的存储空间。
本申请实施例中，元数据是指包含了文件的文件名称、文件大小在内的文件信息；缩略图是指一张图片按照一定比例缩小后的图片，缩略图所占存储空间是非常小的。预设屏幕分辨率的图片以及图片的原始数据虽然都是图片，但是其所占的存储空间也是不同。预设屏幕分辨率的图片所占的空间也是小于图片的原始数据所占的空间。
可选地，当第二电子设备检测到用户在第一应用程序下的搜索框中输入关键词后，第 二电子设备可以根据关键词、本地元数据的索引以及从第一电子设备接收的元数据的索引，显示搜索结果。
示例性的，如图5中的(c)，当手机在搜索框中检测到用户输入关键词“花”后，手机可以根据本地保存的元数据的索引以及其他设备发送的元数据的索引，显示对关键词“花”的搜索结果，其中搜索结果中包括拍摄地点位于“花都区”和“雨花台区”的图片，以及用户名为“小花姐”和“花花”的图片。
示例性的，如图5中的(d)，当手机在搜索框中检测到用户输入关键词“花朵”后，手机可以根据本地保存的元数据的索引以及其他设备发送的元数据的索引，显示对关键词“花朵”的搜索结果，其中搜索结果中包括拍摄时间为2018年的关于“花朵”的图片，以及本地和其他设备上关于“花朵”的图片的数量。
S1109，第一电子设备检测到第一应用程序下的文件发生变化。
S1110，第一电子设备向第二电子设备发送更新后的一个或者多个文件的元数据。
示例性的，以图片为例，若华为M7上检测到用户使用相机拍摄了2张图片，则华为M7保存的图片的个数从80张增加至82张。那么华为M7可以向当前手机发送更新后的元数据。例如，华为M7可以向当前手机发送新增的2张图片的元数据，或者，也可以发送新增的两张图片的元数据以及对应的缩略图。
当第一电子设备上的文件减少时，那么第一电子设备可以向第二电子设备发送减少后所有文件的元数据，并指示第二电子设备使用所述第一电子设备新发送的数据覆盖之前的数据。或者，第一电子设备也可以指示哪些文件减少了，从而使得第二电子设备将相应文件的元数据删除。
本申请实施例中，当第一电子设备保存的共享文件中元数据发生变化时，例如，第一电子设备检测到用户在共享文件中添加了部分文件或者减少了部分文件，那么第一电子设备可以向第二电子设备发送更新后的元数据，这样第二电子设备可以及时更新第一电子设备中共享文件的元数据，并向用户展示第一电子设备上保存的文件的变化情况。
