下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。其中,在本申请实施例的描述中,除非另有说明,“/”表示或的意思,例如,A/B可以表示A或B;本文中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,在本申请实施例的描述中,“多个”是指两个或多于两个。
以下,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中,除非另有说明,“多个”的含义是两个或两个以上。
在进行应用界面跨设备显示时,例如将应用界面由一个终端设备(如第二设备)迁移至另一个终端设备(如第一设备)上供用户操作时,为了不进行相应APP安装,作为一种可能的实现方式,第二设备可以通过投屏技术(如同源投屏技术或异源投屏技术等)将应用界面投屏至第一设备。但是,投屏技术需要耗费巨大的***编解码资源。示例性的,首先,第二设备将应用界面渲染到虚拟屏幕(virtual display)上。然 后,第二设备将虚拟屏幕对应的Surface编码成标准视频流传输到第一设备上。之后,第一设备解码接收到的标准视频流。最后,第一设备显示第二设备投屏的应用界面。另外,投屏技术还会有屏幕色差、显示时延等问题。
作为另一种可能的实现方式,可以通过开发与应用适配的轻应用、快应用或者小程序等,使得第一设备不用安装应用,而是直接打开与应用适配的轻应用、快应用或者小程序等,实现应用界面跨设备显示。但是,这种方法需要第三方进行适配轻应用、快应用或者小程序等的开发,花费较高。另外,相比于原生应用,轻应用、快应用或者小程序等能够实现的功能和界面显示也会大打折扣。其中,原生应用是指能直接运行于当前操作***的应用程序。
基于上述考虑,本申请实施例提供了应用界面跨设备显示方法,该方法可以用于在一个设备上跨设备运行另一个设备中安装的应用的过程中。例如,该方法可以用于将应用界面由一个终端设备(如第二设备)迁移至另一个终端设备(如第一设备)上显示的过程中。又如,该方法可以用于在一个终端设备(如第一设备)上启动安装在另一个终端设备(如第二设备)上的应用的过程中。
例如,本申请实施例提供的方法可以用于图1A所示智能手机1上的视频播放界面跨设备显示在智能手机2上的过程中。示例性的,在视频播放界面跨设备显示在智能手机2之后,智能手机1和智能手机2的界面由图1A所示状态变化为图1B所示状态。
需要说明的是,本申请实施例不限定在一个设备(如第一设备)上跨设备运行另一个设备(如第二设备)中安装的应用之后,第二设备上显示的具体界面。例如,在视频播放界面跨设备显示在智能手机2之后,智能手机1还可以显示主界面(如图1B所示手机桌面),与智能手机2同步显示上述应用界面(如图1C所示)或者显示上述应用界面的上一级应用界面等。
其中,本申请实施例提供的应用界面跨设备显示方法的基本思路是:一个设备(如第一设备)可以在有跨设备启动另一个设备(如第二设备)中安装的应用的需求时,从第二设备获取应用数据,以及通过模拟发起开始活动(startActivity)、启动进程等,以实现不安装相应应用程序,但是正常启动该应用的目的。
进一步的,在一些实施例中,一个设备(如第一设备)可以在有将应用界面从另一个设备(如第二设备)迁移至该设备的需求时,从第二设备获取应用数据和用户数据,以及通过模拟发起开始活动(startActivity)、启动进程、加载用户数据等,以实现不安装相应应用程序,但是正常接续之前第二设备上显示的应用界面的目的。
基于本申请实施例提供的应用界面跨设备显示方法,第一设备无需安装相应APP,便可以快速、方便地实现应用跨设备运行和应用界面跨设备显示。另外,基于本申请实施例提供的应用界面跨设备显示方法,第一设备可以实现与原生应用一致的应用功能和界面显示等。
作为一种示例,终端设备(如第一设备和第二设备)可以包括但不限定于个人计算机(personal computer,PC)、智能手机、上网本、平板电脑、智能手表、智能手环、电话手表、智能相机、掌上电脑、个人数字助理(personal digital assistant,PDA)、便携式多媒体播放器(portable multimedia player,PMP)、增强现实(augmented reality, AR)/虚拟现实(virtual reality,VR)设备、电视机或人机交互场景中的体感游戏机等。本申请对终端设备的具体功能和结构不做限定。

需要说明的是,图2所示终端设备包括的硬件模块只是示例性地描述,并不对终端设备的具体结构做出限定。例如,若终端设备是PC,那么终端设备还可以包括键盘、鼠标等部件。
以包括分层架构的
***的终端设备为例,如图3所示,终端设备的软件可以分成若干个层,每一层都有清晰的角色和分工。层与层之间通过软件接口通信。如图3所示,终端设备的软件结构从上至下可以分为三层:应用程序层(简称应用层),应用程序框架层(简称框架层),***库,安卓运行时和内核层(也称为驱动层)。
其中,应用程序层可以包括一系列应用程序包。为方便描述,以下将应用程序简称为应用。终端设备上的应用可以包括在终端设备出厂前,安装操作***时安装在终端设备中的应用(如相机,图库,日历,通话,蓝牙,音乐,视频,短信息等应用),也可以包括用户通过应用商店等途径下载安装的应用(如
电子邮箱,地图,导航等应用)本申请实施例不予限定应用的具体类型和来源。
在本申请实施例中,终端设备上的应用可以包括用于应用负责应用界面迁移服务的应用(如图3所示平行空间应用)。作为一种示例,在本申请实施例中,平行空间应用可以用于支持终端设备进行跨设备应用数据传输、跨设备应用列表展示、跨设备用户数据传输、跨设备硬件信息传输、应用界面迁移等。
需要说明的是,图3仅作为一种提供应用界面迁移服务的方式和跨设备通信的方式示例,本申请不限定终端设备提供应用界面迁移服务和跨设备通信的具体方式。例如,终端设备中还可以集成有用于提供应用界面迁移服务和跨设备通信的功能模块或者功能接口。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface,API)和编程框架。如图3所示,应用程序框架层可以提供包括服务进程(Service)和客户进程(Client)所实现的接口。
如图3所示,客户进程(Client)包括活动管理(activity manager,AM)、程序包管理(package manager,PM)和网络管理(network management,NM)。如图3所示,与之对应的服务进程(Service)可以包括活动管理服务(activity manager service,AMS)、程序包管理服务(package manager service,PMS)和网络管理服务(network management service,NMS)。
其中,AMS是
***中核心的服务之一,主要用于负责Activity的管理,负责***中各组件的启动、切换、调度及应用进程的管理和调度等工作。具体的,AMS中定义了分别用来保存进程(Process)、活动(Activity)和任务(Task)的数据类。其中,进程(Process)对应的数据类可以包括进程文件信息、进程的内存状态信息和进程中包含的Activity、Service等。
在
***中,Activity调度的基本思路是这样的:各应用进程在要启动新的Activity或者停止当前的Activity时,向AMS报告。AMS在内部为所有应用进程都做了记录,当AMS接到启动或停止的报告时,首先更新内部记录,然后再通知相应客户进程(Client)运行或者停止指定的Activity。由于AMS内部有所有Activity的记录,因此能够调度这些Activity,并根据Activity和***内存的状态自动关闭后台的Activity。
在本申请实施例中,应用程序框架层还用于改变***API的能力,例如具备对API调用事件的截取(hook)能力。其中,截取是指在事件传送到终点前截获并监控事件 的传输。例如,通过如hook技术可以在事件传送到终点前,像个钩子钩上该事件,及时处理并响应该事件。
在一些实施例中,应用程序框架层还可以包括用于负责窗口管理的窗口管理服务器(window manager service,WMS),输入事件管理服务器(input manager service,IMS)内容提供器,视图***,电话管理器,资源管理器,通知管理器等(图3中未示出)。
***库可以包括多个功能模块。例如:表面管理器(surface manager),媒体库(Media Libraries),三维图形处理库(例如:OpenGL ES),2D图形引擎(例如:SGL)等。
内核层是硬件和软件之间的层。内核层可以包含显示驱动,输入/输出设备驱动(例如,键盘、触摸屏、耳机、扬声器、麦克风等),设备节点,摄像头驱动,音频驱动以及传感器驱动等。用户通过输入设备进行输入操作,内核层可以根据输入操作产生相应的原始输入事件,并存储在设备节点中。输入/输出设备驱动可以检测到用户的输入事件。例如,麦克风可以检测到用户发出的语音,触摸屏可以检测到用户的触控操作,键盘可以检测到用户输入的信息或者操作(如选择操作)等。
在本申请一些实施例中,第一设备与第二设备中安装的操作***的大版本一致,如第一设备与第二设备中安装的操作***的主版本号相同。
在本申请一些实施例中,第一设备与第二设备中安装的操作***的版本一致,如主版本号、子版本号、修订版本号等均相同。
以下将以应用形式提供应用界面迁移服务(如平行空间应用)为例,结合附图,对本申请实施例中用于负责应用界面迁移服务的应用(如图3所示平行空间应用,本申请实施例不限定具体名称)做具体介绍。
在本申请实施例中,第一设备与第二设备中安装有平行空间应用。平行空间应用在运行时可以拉起平行空间用户界面进程和平行空间服务进程。其中,平行空间用户界面进程用于进行应用启动界面显示和管理。例如,平行空间用户界面进程用于负责接收用户对屏幕发起的触控事件(如点击、长按、触摸等事件),并跳转至相应界面。
示例性的,第二设备拉起的平行空间用户界面进程可以用于向用户展示应用列表界面,应用列表界面包括第一设备上安装的多个应用的信息(如应用图标)。平行空间服务进程用于复刻(Fork)应用运行的宿主进程,加载应用代码和资源,关联至相应进程,虚拟Framework软件开发工具包(software development kit,SDK),进行原生AM/PM/NM代理,隔离预设调用(如硬件调用等),创建传输通道服务,资源获 取,功能调用等。
示例性的,平行空间服务进程可以采用RESTful(表现层状态转化***)或者远程过程调用(remote procedure call,RPC)进行资源获取和/或功能调用等。例如,可以根据调用发生的区域确定具体技术,例如在进行服务外部调用时采用RESTful进行资源获取和/或功能调用,在进行服务内部调用时采用采用RPC进行资源获取和/或功能调用。其中,RESTful是指满足表现层状态转化(representational state transfer,REST)的***,如满足REST的客户机/服务器(client/serve,C/S)结构、分层***、接口等。关于RESTful***和RPC的具体介绍,可以参考常规技术,本申请实施例不做赘述。
在本申请一些实施例中,为了保证应用界面迁移服务能够提供更好的服务,平行空间应用可以具有较高的***权限。例如,平行空间应用可以在设备开机后始终运行在后台,以便可以随时提供应用界面迁移服务。
在本申请一些实施例中,终端设备(如第二设备)可以具备向用户展示与其建立了通信连接的其它终端设备(如第一设备)上安装的应用信息的能力,以便用户根据实际需求选择跨设备运行的应用。
作为一种示例,第一设备与第二设备之间可以通过交换APP的业务数据(如应用的安装包数据等)以支持第二设备展示第一设备上安装的应用信息的能力。
以在第一设备上跨设备运行安装在第二设备上的应用A为例,示例性的,在第一设备与第二设备之间建立通信连接之后,当平行空间应用在第二设备和第一设备中运行时,首先,如图4中S401所示,第二设备中运行的平行空间应用获取第二设备的业务数据。其中,第二设备的业务数据包括第二设备中安装的应用或者第二设备中当前运行(包括前台运行和/或后台运行)应用(如包括应用A)的安装包数据。基于业务数据可以进行跨设备应用信息展示。
然后,如图4中S402所示,第二设备通过建立的通信连接向第一设备发送上述业务数据。对应的,第一设备可以通过平行空间应用所提供的服务从第二设备接收上述业务数据。
接着,第一设备会拉起平行空间用户界面进程,以在第一设备显示屏上展示第二设备的业务数据对应的应用信息(如应用列表)。例如,该应用列表包括多个应用的应用图标。其中,第一设备展示第二设备上多个应用的应用图标用于为用户提供快捷地、在第一设备上跨设备运行第二设备中任意应用的使用体验。如图4中S403所示,第一设备根据平行空间应用获取的业务数据显示应用列表界面。其中应用列表界面包括应用A的应用图标。
之后,如图4中S404所示,响应于接收到用户在应用列表界面上对应用A的选择操作,第一设备通过平行空间应用从第二设备获取(如下载)应用A的应用数据。其中,应用A的应用数据由平行空间应用从第二设备存储空间中获取,第一设备可以直接从平行空间应用下载应用A的应用数据。在一些实施例中,应用A的应用数据可以包括但不限定于应用A的应用信息,权限信息,应用程序包,资源文件(如res文件),库文件(如lib文件)等。
最后,如图4中S405所示,第一设备中运行的平行空间应用在不安装应用A的情况下,根据获取的应用A的应用数据将应用A加载到第一设备内存并运行。
进一步的,若图4所示应用A当前正运行在第二设备中,即上述跨设备运行应用场景具体是将第二设备上的应用A界面迁移至第一设备,使得第一设备可以接续第二设备对应用A界面的显示。如图4中S406所示,第一设备还可以从第二设备获取(如下载)应用A的用户数据。其中,应用A的用户数据由平行空间应用从第二设备存储空间中获取,第一设备可以直接从平行空间应用下载应用A的用户数据。在一些实施例中,应用A的用户数据可以包括但不限定于应用A的账号信息、历史使用数据(如聊天记录、播放记录、浏览记录等)等。以及,如图4中S407所示,第一设备将应用A的用户数据加载至应用A中。
在本申请另一些实施例中,终端设备(如第二设备)可以具备根据用户在该设备上的操作,将该设备上运行的应用界面迁移至与其建立了通信连接的其它终端设备(如第一设备)上接续显示的能力,以便用户根据实际需求选择要迁移的应用界面。
如图5中S501所示,响应于接收到用户将应用A的界面迁移到第一设备的操作,第二设备通过平行空间应用获取应用A的应用数据。然后,如图5中S502所示,第二设备通过建立的与第一设备之间的通信连接,向第一设备发送上述应用数据。之后,如图5中S503所示,第一设备中运行的平行空间应用在不安装应用A的情况下,根据获取的应用A的应用数据将应用A加载到第一设备内存并运行。最后,如图5中S504,第一设备从第二设备获取应用A的用户数据。以及,如图5中S505所示,第一设备将应用A的用户数据加载至应用A中。
需要说明的是,图4和图5仅以第一设备先从第二设备获取应用数据,再从第二设备获取用户数据作为示例。本申请实施例并不限定应用数据和用户设备获取的具体形式和时机。例如第一设备也可以同时从第二设备获取用户数据和应用数据。又如,第一设备可以在根据应用数据加载应用的过程中,从第二设备获取应用的用户数据。
作为一种示例,第一设备与第二设备可以基于远程双端通信(remote proxy)技术传输相关数据。
可以理解,相比于第一设备同时从第二设备获取用户数据与和应用数据,第一设备先从第二设备获取应用数据,再在根据应用数据加载应用的过程中,从第二设备获取应用的用户数据的方式可以加快应用界面跨设备显示。其原因在于,该方式可以减小应用数据的传输时间,进而便于第一设备及时加载并运行应用。
在一些实施例中,为了便于后续业务开发,在图4所示S404或图5所示S502,第一设备可以通过REST API从第二设备获取(如下载)应用A的应用数据。其中,REST API由于不需要额外的协议,可以直接基于超文本传输协议(hyper text transfer protocol,HTTP)通过自适应动词增加、删除、修改等实现资源获取和功能调用等,因此具有轻量化特点。另外,REST API的数据描述简单,例如一般通过基于JavaScript语言的轻量级的数据交换格式(JavaScript object notation,JSON)或者可扩展标示语言(extensive markup language,xml)进行数据通讯。
可以理解,基于图4所示跨设备应用界面显示方法,第一设备可以向用户展示第二设备上安装的应用信息,根据用户的实际跨设备应用运行需求,在不安装相应应用程序的前提下,平滑地实现应用跨设备运行和应用界面跨设备显示,且与原生应用的应用功能和界面显示一致。基于图5所示跨设备应用界面显示方法,第二设备可以根 据用户的实际跨设备应用运行需求和用户在该设备上的操作,将该设备上运行的应用界面平滑迁移至与其建立了通信连接的第一设备上接续显示,不丢失任务进程,且第一设备无需安装应用A。
进一步的,在图4和图5跨设备应用界面显示完成之后,第一设备可以删除应用数据和/或用户数据,如应用程序包等相关数据,以实现应用相关进程的随用随走,并不会对第一设备的后续使用造成任何影响。因此,该方法极大地提高了应用界面跨设备显示使用体验。
可选的,在图4和图5跨设备应用界面显示完成之后,第一设备可以将最新的应用数据和/或用户数据,如应用程序包等相关数据回传至第二设备,以便第二设备对应用界面的接续显示。
以下将结,实施例1和实施例2,以第一设备跨设备运行第二设备上安装的应用为例,对本申请实施例提供的跨设备应用界面显示方法做具体介绍。
实施例1:
在本申请实施例1中,在第一设备与第二设备建立通信连接之后,第一设备和第二设备具备向用户展示对端设备上安装的应用信息的能力,以便用户根据实际需求选择跨设备运行的应用。
如图6所示,本申请实施例提供的跨设备应用界面显示方法主要可以包括初始阶段和跨设备运行阶段。其中,初始阶段用于进行通信连接建立和跨设备应用列表展示,如图6所示,初始阶段包括S601-S603。跨设备运行阶段用于进行应用数据获取和应用跨设备运行,如图6所示,跨设备运行阶段包括S604-S606。其中,第一设备与第二设备中运行有用于负责应用界面迁移服务的应用(如图3所示平行空间应用)。
S601:第一设备与第二设备建立通信连接。
其中,第一设备与第二设备建立通信连接如第一设备与第二设备建立蓝牙连接、WiFi直连或者点对点(peer-to-peer,P2P连接,第一设备与第二设备接入同一无线局域网等,本申请不限定通信连接的具体方式。
作为一种示例,第一设备与第二设备可以基于设备互联技术建立通信连接。
示例性的,第一设备与第二设备建立通信连接可以包括:首先,第一设备与第二设备通过低功耗蓝牙(bluetooth low energy,BLE)建立信令通道。然后,第一设备与第二设备通过建立的信令通道交换双方通信参数。最后,第一设备与第二设备建立用于数据传输的P2P连接。
作为一种可能的实现方式,设备可以基于设备发现技术建立与已发现设备之间的通信连接。例如,第一设备可以在发现第二设备之后,与第二设备建立通信连接。又如,第二设备可以在发现第一设备之后,与第一设备建立通信连接。
作为另一种可能的实现方式,设备可以基于用户手动输入的设备信息建立与已输入的设备信息所表征的设备之间的通信连接。例如,第一设备接收用户在第一设备上设备发现界面等界面上输入的第二设备的标识,建立与第二设备之间的通信连接。示例性的,第二设备的标识可以是第二设备的媒体访问控制(media access control,MAC)地址、身份号(identity,ID)、国际移动设备身份码(international mobile equipment identity,IMEI)等,本申请实施例不限定。
作为另一种可能的实现方式,设备还可以基于碰一碰、靠近、扫描设备码等建立与其它设备之间的通信连接。关于设备之间建立通信连接的具体方式和过程,可以参考常规技术,本申请实施例不做赘述。
S602:第一设备与第二设备进行业务数据交换。
其中,第一设备与第二设备进行业务数据交换包括:第一设备从第二设备获取第二设备的业务数据,以及第二设备从第一设备获取第一设备的业务数据。
在本申请实施例中,业务数据包括但不限于设备中安装的应用或者当前设备中运行(包括前台运行和/或后台运行)应用(如包括应用A)的安装包数据。例如,应用安装包数据包括但不限于应用的icon(应用图标)、action(如android.intent.action.MAIN)、category(如android.intent.category.LAUNCHER)、flags和ResovleActivityInfo等。
其中,action用于决定应用的入口Activity,也就是我们启动应用时首先显示哪一个Activity。category用于决定应用程序在程序列表中的显示。flags即Activity的标记位,如用于标记Activity的启动模式、运行状态等。ResovleActivityInfo用于存储应用程序包如安卓应用程序包(Android Package,APK)的meta数据。示例性的,包含了应用所有的界面活动(Activity)信息,打开方式或跳转方式等。基于上述业务数据,可以确定后续应用列表界面中应用图标的显示。
作为一种可能的实现方式,在第一设备与第二设备建立通信连接之后,第一设备和第二设备可以通过用于负责应用界面迁移服务的应用(如平行空间应用),调用PMS(程序包管理服务)获取各自的业务数据。
进一步的,在一些实施例中,第一设备和第二设备可以在平行空间应用获取各自的业务数据之后,通过已建立的通信连接从对端设备获取业务数据。
在另一些实施例中,在第一设备和第二设备通过平行空间应用获取各自的业务数据之后,第一设备和第二设备可以在用户开启应用界面迁移服务时,通过已建立的通信连接从对端设备获取业务数据。其中,用户开启应用界面迁移服务如用户在第一设备和/或第二设备上打开用于负责应用界面迁移服务的应用(如平行空间应用)。本申请不限定第一设备与第二设备进行业务数据交换的具体时机。
可以理解,在第一设备与第二设备进行业务数据交换之后,第一设备便具备展示第二设备应用列表的能力,同样,第二设备也具备展示第一设备应用列表的能力。例如,第一设备和第二设备均具备通过平行空间应用界面展示对端的应用列表的能力。基于第一设备和第二设备的该能力,用户可以根据实际使用场景和需要在任意设备上拉起应用列表界面。
S603:第一设备响应于用户打开应用列表界面的操作,根据第二设备的业务数据显示应用列表界面。
其中,应用列表界面包括至少一个应用图标或者悬浮可滑动页面。该至少一个应用图标或者悬浮可滑动页面对应的应用安装在第二设备中和/或运行在第二设备中。作为一种示例,应用列表界面是平行空间应用的启动界面(也称HomeScreen)。
如前文所述,用于负责应用界面迁移服务的应用,如平行空间应用在运行时可以拉起平行空间用户界面进程和平行空间服务进程。其中,平行空间应用可以通过模拟 PMS,创建与PMS功能一致的虚拟程序包管理服务(virtual package manager service,VPMS)和虚拟活动管理服务(virtual activity manager service,VAMS)。如图7所示,平行空间服务进程可以调用VPMS和VAMS。平行空间用户界面进程可以调用虚拟程序包管理(virtual package manager,VPM)和虚拟活动管理(virtual activity manager,VAM)。
在一些实施例中,为了保证平行空间用户界面进程和平行空间服务进程之间通信的安全性,平行空间用户界面进程和平行空间服务进程之间可以基于进程间通信(inter-process communication,IPC)技术进行通信。
在一种可能的实现方式中,第一设备可以通过拉起平行空间用户界面进程,以根据第二设备的业务数据所指示的如action、category等Intent信息在第一设备显示屏上显示包括有应用图标的平行空间应用的启动界面。
可以理解,第一设备显示的应用列表界面中应用图标所表示的应用,对于用户来说,就像安装在第一设备本地一样,用户可以通过在应用列表界面上操作(如点击任意应用图标),在第一设备上开启第二设备中的任意应用。
请参考图8,图8示出了三种应用列表界面示例。如图8中的(a)所示,应用列表界面以平行空间应用界面的形式展示。对于这种情况,用户打开应用列表界面的操作如用户在平行空间应用界面上开启应用列表展示功能的操作。如图8中的(b)所示,应用列表功能可以以第一设备桌面上一个功能文件夹(如图8中的(b)所示“第二设备”文件夹)的形式展示,应用列表界面是打开该功能文件夹后的界面。对于这种情况,用户打开应用列表界面的操作如用户打开上述功能文件夹的操作。如图8中的(c)所示,应用列表功能可以以桌面上一个功能图标(如图8中的(c)所示“迁移”功能图标)的形式展示,应用列表界面可以包括多个悬浮可滑动页面。对于这种情况,用户打开应用列表界面的操作如用户点击上述功能图标的操作。
在一些实施例中,用户可以在第一设备上打开应用列表界面,通过在应用列表界面上的操作,实现应用界面从第二设备向第一设备的迁移。
例如,假设用户通过第一设备的应用列表界面打开第一应用,则第一设备执行以下S604-S606:
S604:响应于接收到对应用列表界面上第一应用的打开操作,第一设备从第二设备获取第一应用的应用数据。
其中,第一应用的应用数据可以包括但不限定于应用信息,权限信息,应用程序包,资源文件,lib文件等。
其中,应用信息如应用名称、应用所能提供的功能、服务等。权限信息如应用访问设备硬件(如相机、麦克风、存储单元等)的权限,应用访问其它应用(如通信录、位置信息、通话记录、信息等)的权限等。应用程序包如APK。资源文件如res文件。lib文件即静态数据连接库。
示例性的,第一应用的应用数据可以由第二设备中安装的平行空间应用从第二设备的存储空间中获取。通常,第二设备在安装完应用之后,会将应用的应用数据保存在存储空间中。例如,第一应用的应用数据可以存储在以下路径下:/data/app/。示例性的,第一应用的应用程序包的保存路径为/data/app/com.xxx.xx/第一应用.apk,其中 com.xxx.xx如com.android.vending。
以
***为例,可以理解,每一个APP在开发时,都会被定义一个MainActivity,MainActivity通常被配置在AndroidManifest文件中。例如,在配置AndroidManifest文件时,将Activity的action指定为android.intent.action.MAIN,将category指定为android.intent.category.LAUNCHER,表示通过Intent启动此Activity时,只接受category为LAUNCHER的Intent。基于此,平行空间用户界面进程在接收到用户在启动界面上对应用图标的触控事件(如点击、长按、触摸等事件)时,会根据用户的操作对象应用,得到应用的Intent,并通过这个Intent启动应用的MainActivity,从而启动应用。
对于一些应用数据量较大的应用,应用数据的传输可能会花费较长的时间。例如,
应用程序包的文件大小如140M(兆),第二设备向第一设备进行数据传输的速度如10M/S(兆/秒),因此,第二设备接收到对应用列表界面上第一应用的打开操作之后,最快会在14秒之后才能开启
14秒的延迟会给用户带来非常差的体验。
为了避免由于应用数据量较大导致的第二设备向第一设备传输应用数据花费时间较长,造成的第一设备对用户对应用列表界面上第一应用的打开操作响应的不及时的问题,在一些实施例中,第二设备可以在向第一设备传输第一应用的应用数据时,先向第一设备传输第一应用的第一部分,以加速第一设备加载并运行第一应用的速度。然后,第一设备在加载并运行第一应用的过程中,再从第二设备获取第二部分。其中,第一部分如第一应用的最小可运行版本的应用数据(如apklite包),第二部分如其它未传输的应用数据(如dex文件,so文件,res文件或arsc文件等其它文件)。
其中,so文件即lib文件。res文件即编译之后的资源文件。dex文件如classes.dex文件。classes.dex文件是
***中的可执行文件。
虚拟机可以支持classes.dex文件的字节码文件格式。arsc文件如resources.arsc文件。resources.arsc文件是
资源打包工具(
assets packaging tools,AAPT)生成的资源索引表。resources.arsc文件记录了所有的应用程序资源目录的信息,包括每一个资源名称、类型、值、ID以及所配置的维度信息。
可以理解,第一应用的最小可运行版本的应用数据中包括能够成功启动第一应用的必要文件。作为一种示例,第一应用的最小可运行版本的应用数据包括第一应用的证书文件、manifest文件和class.dex文件。
其中,manifest文件用于定义入口Activity和IntentFilter。示例性的,IntentFilter可以定义在AndroidManifest.xml文件中。IntentFilter用于声明组件接受哪种Intent(包括action、category等)。例如,若为一个Activity设置了IntentFilter,则可以在应用内或者其它应用中,用特定的隐式Intent启动这个Activity;若没有为Activity设置IntentFilter,则只能通过显示Intent启动这个Activity。
为了避免由于应用数据量较大导致的第二设备向第一设备传输应用数据花费时间较长,造成的第一设备对用户对应用列表界面上第一应用的打开操作响应的不及时的问题,在另一些实施例中,第二设备还可以在应用数据量大于预设阈值时,提示用户(如弹窗提示用户等)选择数据传输策略,并且根据用户选择的数据传输策略选择向第一设备发送第一应用的应用数据。其中,数据传输策略如传输所有应用数据、先传 输最小可运行版本等。
或者,第二设备还可以在应用数据量大于预设阈值时,提示用户(如弹窗提示用户等)选择应用界面跨设备显示策略,并且根据用户选择的应用界面跨设备显示策略执行相应任务。其中,应用界面跨设备显示策略如投屏(如同源投屏或异源投屏等)、APP安装、继续传输应用数据(如先传输最小可运行版本)等。
作为一种示例,在接收到对应用列表界面上第一应用的打开操作之后,如图7所示,平行空间用户界面进程可以向平行空间服务进程请求第一应用的应用数据(如图7中S701所示)。例如,平行空间用户界面进程可以向平行空间服务进程发送Binder请求,以请求第一应用的应用数据。然后,平行空间服务进程可以通过VPMS,向第二设备的平行空间服务进程请求第一应用的应用数据(如图7中S702所示)。例如,平行空间服务进程可以通过VPMS,向第二设备的平行空间服务进程发送Socket请求,以请求第一应用的应用数据。进一步的,如图7所示,第二设备的平行空间服务进程通过VPackageLite,解析应用数据,确定第一应用的最小可运行版本所需要的应用数据,(如图7中S703所示)。然后,通过VPMS将第一应用的最小可运行版本的应用数据发送给第一设备,第一设备可以直接在内存中对第一应用的最小可运行版本的应用数据(如包括APK)进行解析(如图7中S704-1和S704-2所示)。
其中,在本申请实施例中,对应用列表界面上第一应用的打开操作可以包括但不限于对应用列表界面上第一应用的点击(如单击、双击等)操作、长按后选择打开选项的操作、右键后选择打开选项的操作、拖动至预设位置的操作,或者其它预设操作等。以应用列表界面如图8所示为例,对应用列表界面上第一应用,如
的打开操作可以如对图8中的(a)或者如对图8中的(b)所示应用列表界面上
应用图标的点击、长按后选择打开选项的操作、右键后选择打开选项等操作,或者将如对图8中的(c)所示
悬浮可滑动页面拖动至迁移启动图标处的操作。
S605:第一设备解析第一应用的应用数据,模拟发起第一应用的开始活动(startActivity)。
在本申请实施例中,第一设备中用于负责应用界面迁移服务的应用,如平行空间应用可以提供虚拟的服务(如VAMS、VPMS、VNMS等)和应用编程接口(application programming interface,API)调用能力,以便在用户选择在第一设备跨设备运行第二设备中安装的第一应用时通过模拟发起开始活动(startActivity)、启动进程等,以实现不安装相应应用程序,但是正常运行该应用的目的。
如图7中S705所示,第一设备的平行空间用户界面进程可以通过VAM,指示平行空间服务进程模拟发起第一应用的开始活动(startActivity),以开启第一应用进程。
进一步的,如图7中S706所示,第一设备根据应用数据所指示的intent发起第一应用的开始活动(startActivity),如启动应用的占位Activity(StubActivity),创建第一应用进程,并且为第一应用启动提供标准环境。
以
***为例,标准环境如标准zygote环境。其中,在
***中,大多数应用进程和***进程都是通过标准zygote环境生成的。示例性的,基于zygote环境,可以创建第一应用进程和第一应用的应用线程(ApplicationThread)。其中,应用线程(ApplicationThread)用于提供Binder通信接口。以
***为例,示例 性的,在模拟发起开始活动(startActivity)时,通常会进入hooked StartActivity方法,该方法在发现需要启动插件内部的Activity时,会进行ActivityInfo解析,然后通过VAM调用VAMS对应的方法,发起开始活动(startActivity)以及创建进程。
然后,如图7中S707所示,第一应用进程通过调用自身回调初始化第一应用进程,接管API、AMS、PMS,以解析真正要启动的Activity(如实际要加载的应用程序代码位置,应用数据中的相应文件(如dex文件,so文件和res文件等)),进而将解析到的数据映射到第一应用进程的内存空间。
S606:第一设备运行第一应用。
如图7中S708所示,第一应用进程在应用线程(ApplicationThread)创建之前通过hook手段,调用桩函数将应用程序包名修改成真正的包名,为第一应用进程创建上下文(context),进而成功创建第一应用的应用线程(ApplicationThread)。其中,上下文(context)用于访问应用相关的各种资源文件(如图片、布局文件等)。至此,第一应用进程进入标准(standard)模式的第一应用的Activity的生命周期。
可以理解,至此,第一设备完成对第二设备上安装的应用的跨设备运行。
其中,在本申请实施例中,第一设备通过Framework层根据从第二设备获取的第一应用的应用数据模拟发起第一应用的开始活动,启动以及运行第一应用。示例性的,第一设备通过调用自身回调,接管API、AMS、PMS等Framework层的能力,经过应用进程初始化、应用数据解析和映射、hook后修改程序包名、创建上下文等,成功启动以及运行第一应用。因此,操作***会把第一应用当做安装在第一设备中的应用,按照第一应用的标准(standard)模式生命周期运行第一应用。因此,基于本申请实施例提供的方法可以实现应用的跨设备使用体验。
进一步的,在本申请一些实施例中,为了保证第一应用在第一设备上的正常启动。第一设备还可以实时检测是否收到代码段的缺失(如class not found),so不能加载等异常告警。以及,在检测到异常告警时,从第二设备获取对应文件(如dex文件),重新加载并映射到第一应用进程中。在截取(hook)到异常告警时,如图9中S709所示,第一应用进程可以调用HookManager向第二设备(如图9所示第二设备中的APK管理类(VApkManager))请求对应文件(如dex文件)。然后,如图9中S710所示,第一应用进程可以调用HookManager将获取的对应文件(如dex文件)重新加载并映射到第一应用进程中。
进一步的,对于第一设备启动第二设备上安装的第一应用,且登录第二设备上第一应用所登录账号的情况,如图10所示,本申请实施例提供的方法的跨设备运行阶段还可以包括S1001-S1002:
S1001:第一设备从第二设备获取第一应用的用户数据。
其中,第一应用的用户数据如第一应用的账号信息。
示例性的,第一应用的用户数据可以由第二设备中安装的平行空间应用从第二设备的存储空间中获取。通常,在用户使用应用的过程中,相关用户数据会实时保存在存储空间中。例如,第一应用的用户数据可以存储在以下路径下:/data/data/。示例性的,第一应用的账号信息的保存路径为/data/data/com.xxx.xx/登录信息,其中com.xxx.xx如com.android.vending。
S1002:第一设备将第一应用的用户数据加载至第一应用,登录对应账号。
在一些可能的情况中,如对于第一设备接续显示第二设备上应用界面(如第一界面)的情况,如图11所示,本申请实施例提供的方法的跨设备运行阶段还可以包括S1101-S1102:
S1101:第一设备从第二设备获取第一应用的用户数据。
其中,第一应用的用户数据可以包括但不限定于第一应用的账号信息、历史使用数据等。其中,历史使用数据如聊天记录、播放记录、浏览记录等相关数据。
以第一应用是
应用为例,第一应用的用户数据包括微信账号信息、聊天记录、通信录、白名单/黑名单、朋友权限、朋友圈动态、公众号、收藏等相关信息。以第一应用是视频应用为例,第一应用的用户数据包括视频应用账号信息、播放记录、最近播放进度、收藏等相关信息。本申请不限定第一应用的用户数据的类型,视具体应用而定。
示例性的,第一应用的用户数据可以由第二设备中安装的平行空间应用从第二设备的存储空间(如/data/data/路径下)中获取。
S1102:第一设备将第一应用的用户数据加载至第一应用中,接续显示第一应用的第一界面。
其中,在本申请实施例中,第一设备接续显示第一应用的第一界面是指第一设备不丢失第二设备显示第一应用的第一界面时对应的应用进程,继续根据该应用进程显示界面。
需要说明的是,本申请上述实施例仅以第一设备中未安装第一应用作为示例。实际上,第一设备中也有可能已经安装有第一应用。
对于第一设备中已经安装有第一应用的情况,当第一设备接续显示第一应用的第一界面时,在一些实施例中,本申请实施例提供的应用界面跨设备显示方法包括图11所示S601-S603和S1101,然后,第一设备启动安装在第一设备中的第一应用,并执行S606和S1102。可见,本申请实施例既可以适用于第一设备中未安装第一应用的情况下第一应用的跨设备启动和第一应用界面的迁移,也可以适用于第一设备中已经安装有第一应用的情况下第一应用界面的迁移,通用性强。
在一些实施例中,为了安全起见,一些应用在跨设备运行时,需要进行设备或用户等相关信息校验,因此当在第一设备上运行第二设备上安装的应用时,第一应用可能会调用校验信息。示例性的,校验信息如硬件校验信息(如设备ID)或者用户身份识别卡(subscriber identity module,SIM)校验信息等。对于这种情况,为了保证第一应用在第一设备上的正常运行,第一设备可以截取(hook)对上述校验API的调用,从第二设备获取相关硬件信息(如设备ID)或者验证信息(如验证码)以成功完成校验。
在一些实施例中,为了保证应用界面跨设备显示方法的性能稳定,对于独立资源访问,如内存访问申请、互联网资源访问、摄像头调用等,可以采用***API的常规处理流程调用相应内存、网络和摄像头。
需要说明的是,上述对API调用的截取(hook)场景仅作为示例,本申请不限定截取(hook)API的具体场景、类型等,视具体情况和实际需求而定。
如上文所述,在本申请实施例中,用户可以通过在第一设备上发起跨设备显示第二设备上的应用界面,也可以通过在第二设备上发起将第二设备上的应用界面跨设备显示在第一设备上。上述实施例1具体介绍了用户在第一设备上发起跨设备显示第二设备上的应用界面的情况。关于用户在第二设备上发起将第二设备上的应用界面跨设备显示在第一设备上的情况,应用界面跨设备显示具体过程可以参考以下实施例2。
实施例2:
在本申请实施例2中,在第二设备与第一设备建立通信连接之后,第二设备具备根据用户在该设备上的操作,将该设备上运行的应用界面迁移至第一设备上接续显示的能力。
如图12所示,本申请实施例提供的跨设备应用界面显示方法可以包括S1201-S1205:
S1201:第二设备与第一设备建立通信连接。
关于S1201的具体过程,可以参考实施例中对S601的介绍,这里不做赘述。
S1202:响应于用户打开应用界面迁移功能的操作,第二设备显示可迁移应用列表界面。
其中,可迁移应用列表界面包括至少一个应用图标或者悬浮可滑动页面。该至少一个应用图标或者悬浮可滑动页面对应的应用安装在第二设备中和/或运行在第二设备中。
作为一种示例,应用界面迁移功能的触发入口集成在平行空间应用中。对于这种情况,用户打开用户界面迁移功能的操作如用户在平行空间应用界面上开启应用界面迁移功能的操作,相应的,可迁移应用列表界面以平行空间应用界面的形式展示。
作为另一种示例,应用界面迁移功能可以以第二设备桌面上一个功能文件夹的形式为用户提供服务。对于这种情况,用户打开用户界面迁移功能的操作如用户打开该功能文件夹的操作。相应的,可迁移应用列表界面即打开该功能文件夹后的界面。
作为另一种示例,应用界面迁移功能可以以桌面上一个功能图标的形式为用户提供服务。对于这种情况,用户打开用户界面迁移功能的操作如用户点击上述功能图标的操作。示例性的,可迁移应用列表界面即用户打开用户界面迁移功能后的主界面,如该主界面上包括多个悬浮可滑动页面。
S1203:响应于用户在可迁移应用列表界面上对第一应用的选择操作,第二设备向第一设备发送第一应用的应用数据。
其中,第一应用的应用数据可以包括但不限定于应用信息,权限信息,应用程序包,资源文件,lib文件等。例如,第一应用的应用数据可以存储在以下路径下:/data/app/。
在一些实施例中,若第一应用的应用数据量较大,第二设备可以先向第一设备传输第一应用的第一部分,以加速第一设备加载并运行第一应用的速度。然后,第二设备在第一设备加载并运行第一应用的过程中,再向第一设备发送第一应用的第二部分。其中,第一应用的第一部分如第一应用的最小可运行版本的应用数据(如apklite包),第一应用的第二部分如其它未传输的应用数据(如dex文件,so文件,res文件或arsc文件等其它文件)。通过这种方式可以避免应用数据的传输花费时间较长,造成的第一设备对用户对应用列表界面上第一应用的打开操作响应的不及时的问题。
或者,若第一应用的应用数据量较大,第二设备还可以提示用户(如弹窗提示用户等)选择应用界面跨设备显示策略,并且根据用户选择的应用界面跨设备显示策略执行相应任务。其中,应用界面跨设备显示策略如投屏(如同源投屏或异源投屏等)、APP安装、继续传输应用数据(如先传输最小可运行版本)等。
S1204:第一设备解析第一应用的应用数据,模拟发起第一应用的开始活动(startActivity)。
S1205:第一设备运行第一应用。
关于S1204和S1205的具体过程,可以参考实施例1中对S605和S606的介绍,这里不做赘述。
进一步的,对于第一设备启动第二设备上安装的第一应用,且登录第二设备上第一应用所登录账号的情况,如图12所示,本申请实施例提供的方法的跨设备运行阶段还可以包括S1001-S1002。
或者,进一步的,对于第一设备接续显示第二设备上应用界面(如第一界面)的情况,如图13所示,本申请实施例提供的方法的跨设备运行阶段还可以包括S1101-S1102。
关于S1001-S1002,S1101-S1102的具体过程,可以参考实施例1中的介绍,这里不做赘述。
通过上述实施例1和实施例2可知,基于本申请实施例提供的应用界面跨设备显示方法,通过动态加载来自第二设备的应用程序包(如APK文件),实现在第一设备上直接运行第一应用的目的,且保证应用界面与原生应用的应用功能和界面显示一致。上述方法突破了设备之间的壁垒,极大提高了应用界面跨设备显示的便捷性,方便了跨设备场景下用户的使用体验。
并且,上述方法中,在结束应用界面跨设备显示之后,第一设备可以删除应用程序包应用数据和/或用户数据,如APK文件等相关数据,以实现应用相关进程的随用随走,并不会对第一设备的后续使用造成任何影响,提高了应用界面跨设备显示时的用户体验。示例性的,基于图6所示应用界面跨设备显示方法,第一设备可以在不安装相应应用程序的前提下,通过动态加载来自第二设备的应用程序包(如APK文件),实现在第一设备上直接打开并运行第二设备上安装的应用,且保证应用界面与原生应用的应用功能和界面显示一致。
例如,基于本申请实施例提供的应用界面跨设备显示方法,用户可以通过未安装导航应用的平板电脑,使用手机中已安装的导航应用。其中,平板电脑可以基于本申请实施例提供的应用界面跨设备显示方法,直接开启安装在手机中的导航应用,如图14所示。
基于图10和图12所示应用界面跨设备显示方法,第一设备可以在不安装相应应用程序的前提下,通过动态加载来自第二设备的应用程序包(如APK文件),实现在第一设备上直接以第二设备上该应用已登录的账号运行第二设备上安装的该应用,且保证应用界面与原生应用的应用功能和界面显示一致。
例如,基于本申请实施例提供的应用界面跨设备显示方法,用户可以通过未安装导航应用的平板电脑,使用手机中已安装的导航应用。并且,用户无需手动在平板电 脑中输入导航应用的登录信息。其中,平板电脑可以基于本申请实施例提供的应用界面跨设备显示方法,自动登录手机中导航应用所登录的账号,如图15所示。
基于图11和图13所示应用界面跨设备显示方法,第一设备可以在不安装相应应用程序的前提下,通过动态加载来自第二设备的应用程序包(如APK文件),实现在第一设备上接续第二设备对应用界面的显示,且保证应用界面与原生应用的应用功能和界面显示一致。
例如,基于本申请实施例提供的应用界面跨设备显示方法,用户可以通过未安装
应用的平板电脑,接续显示手机中的
应用界面(如聊天界面、公众号浏览界面、朋友圈浏览界面等)。又如,用户可以通过未安装视频应用的电视机,接续手机中的视频播放。
又如,基于本申请实施例提供的应用界面跨设备显示方法,用户可以通过未安装导航应用的平板电脑,接续显示手机中导航应用界面(如导航界面),如图16所示。
