下面结合图1对手机100的各个部件进行具体的介绍：
处理器101是手机100的控制中心，利用各种接口和线路连接手机100的各个部分，通过运行或执行存储在存储器103内的应用程序，以及调用存储在存储器103内的数据和指令，执行手机100的各种功能和处理数据。在一些实施例中，处理器101可包括一个或多个处理单元；处理器101还可以集成应用处理器和调制解调处理器；其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器101中。举例来说，处理器101可以是多核处理器。
射频电路102可用于在收发信息或通话过程中，无线信号的接收和发送。具体地，射频电路102可以将基站的下行数据接收后，给处理器101处理；另外，将涉及上行的数据发送给基站。通常，射频电路包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器、双工器等。此外，射频电路102还可以通过无线通信和其他设备通信。所述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统、通用分组无线服务、码分多址、宽带码分多址、长期演进、电子邮件、短信服务等。
存储器103用于存储应用程序以及数据，处理器101通过运行存储在存储器103的应用程序以及数据，执行手机100的各种功能以及数据处理。存储器103可以包括存储程序区以及存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)；存储数据区可以存储根据使用手机100时所创建的 数据(比如音频数据、电话本等)。此外，存储器103可以包括高速随机存取存储器，还可以包括非易失存储器，例如磁盘存储器件、闪存器件或其他存储器件等。存储器103可以存储各种操作系统，例如苹果公司所开发的

操作系统等。
触摸屏104可以包括触敏表面104-1和显示器104-2。
其中，触敏表面104-1(例如触控面板)可采集手机100的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触敏表面104-1上或在触敏表面104-1附近的操作)，并将采集到的触摸信息发送给其他器件例如处理器101。触敏表面104-1可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再发送给处理器101，触摸控制器还可以接收处理器101发送的指令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触敏表面104-1。
显示器(也称为显示屏)104-2可用于显示由用户输入的信息或提供给用户的信息以及手机100的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器104-2。触敏表面104-1可以覆盖在显示器104-2之上，当触敏表面104-1检测到在其上或附近的触摸事件后，传送给处理器101以确定触摸事件的类型，随后处理器101可以根据触摸事件的类型在显示器104-2上提供相应的视觉输出。虽然在图1中，触敏表面104-1与显示屏104-2是作为两个独立的部件来实现手机100的输入和输出功能，但是在某些实施例中，可以将触敏表面104-1与显示屏104-2集成而实现手机100的输入和输出功能。可以理解的是，触摸屏104是由多层材料堆叠而成，本申请实施例中只展示出了触敏表面(层)和显示屏(层)，其他层在本申请实施例中不予记载。另外，在本申请其他一些实施例中，触敏表面104-1可以覆盖在显示器104-2之上，并且触敏表面104-1的尺寸大于显示屏104-2的尺寸，使得显示屏104-2全部覆盖在触敏表面104-1下面，或者，上述触敏表面104-1可以以全面板的形式配置在手机100的正面，也即用户在手机100正面的触摸均能被手机感知，这样就可以实现手机正面的全触控体验。在其他一些实施例中，触敏表面104-1以全面板的形式配置在手机100的正面，显示屏104-2也可以以全面板的形式配置在手机100的正面，这样在手机的正面就能够实现无边框的结构。在本申请其他一些实施例中，触摸屏104还可以包括一组或多组传感器阵列，用于触摸屏104在感测用户在其上的触摸事件的同时也可以感测到用户在其上施加的压力等。

Wi-Fi 107，用于为手机100提供遵循Wi-Fi相关标准协议的网络接入，手机100可以通过Wi-Fi 107接入到Wi-Fi接入点，进而帮助用户收发电子邮件、浏览网页和访问流媒体等，它为用户提供了无线的宽带互联网访问。在其他一些实施例中，该Wi-Fi 107也可以作为Wi-Fi无线接入点，可以为其他终端提供Wi-Fi网络接入。
定位装置108，用于为手机100提供地理位置。可以理解的是，该定位装置108具体可以是全球定位系统(global positioning system，GPS)、北斗卫星导航系统等定位系统的接收器。定位装置108在接收到上述定位系统发送的地理位置后，将该信息发送给处理器101进行处理，或者发送给存储器103进行保存。在另外的一些实施例中，该定位装置108可以是辅助全球卫星定位系统(assisted global positioning system，AGPS)的接收器，AGPS是一种在一定辅助配合下进行GPS定位的运行方式，它可以利用基站的信号，配合GPS卫星信号，可以让手机100定位的速度更快；在AGPS系统中，该定位装置108可通过与辅助定位服务器(例如手机定位服务器)的通信而获得定位辅助。AGPS系统通过作为辅助服务器来协助定位装置108完成测距和定位服务，在这种情况下，辅助定位服务器通过无线通信网络与终端例如手机100的定位装置108(即GPS接收器)通信而提供定位协助。
音频电路109、扬声器113、麦克风114可提供用户与手机100之间的音频接口。音频电路109可将接收到的音频数据转换后的电信号，传输到扬声器113，由扬声器113转换为声音信号输出；另一方面，麦克风114将收集的声音信号转换为电信号，由音频电路109接收后转换为音频数据，再将音频数据输出至RF电路102以发送给比如另一手机，或者将音频数据输出至存储器103以便进一步处理。

手机100还可以包括给各个部件供电的电源装置111(比如电池和电源管理芯片)，电池可以通过电源管理芯片与处理器101逻辑相连，从而通过电源装置111实现管理充电、放电、以及功耗管理等功能。
尽管图1未示出，手机100还可以包括摄像头、闪光灯、微型投影装置、近场通信(near field communication，NFC)装置等，在此不予赘述。
在本申请实施例中，两个终端(例如手机A和手机B)之间可以基于有线连接进行数据传输，也可以基于无线连接进行数据传输，还可以同时基于有线连接和无线连接进行数据传输。
例如，手机A和手机B中均具有Wi-Fi功能。如图2所示，手机A可通过其Wi-Fi接入到某一Wi-Fi接入点，手机B也可通过其Wi-Fi接入到该Wi-Fi接入点，这样，手机A与手机B就可以进行数据传输。当然，手机A和手机B也可通过各自的Wi-Fi建立WLAN直连，此时在手机A与手机B之间传输数据时无需额外通过Wi-Fi接入点转发。又或者，手机A(或手机B)也可以作为Wi-Fi接入点与另一手机建立无线连接，从而使用该无线 连接实现数据传输。当然，手机A和手机B也可以通过蓝牙、NFC或4G网络、5G网络等方式建立无线连接，本申请实施例对此不做任何限制。
又例如，如果手机A和手机B中均具有USB接口(USB接口为外设接口的一种)。仍如图2所示，可使用与手机A和手机B的USB接口均适配的USB数据线201建立手机A和手机B之间的有线连接。
其中，上述USB接口的类型具体可以为USB Type A接口、USB Type B接口、Micro USB接口、Mini USB接口或者USB Type C接口等，本申请实施例对此不做任何限制。
其中，上述数据线201两端的接口需要分别与手机A和手机B的USB接口适配。例如，如果手机A和手机B的USB接口均为USB Type C接口，那么，可以使用Type C to Type C(C-to-C)的直连数据线连接手机A和手机B的USB接口。或者，当数据线201两端的接口不是USB Type C接口时，例如，USB数据线201的一端为USB Type C接口，而USB数据线201的另一端为USB Type A接口。此时，可以通过OTG(On The Go)连接器将USB数据线201的USB Type A接口转换为USB Type C接口，进而实现手机A和手机B之间的有线连接。
另外，手机A和手机B通过USB数据线201进行数据传输时可基于USB1.0、USB2.0、USB3.0或USB3.1等任意类型的USB规范，本申请实施例对此不做任何限制。
也就是说，在本申请实施例中，当用户需要在两个终端之间传输数据时，可在这两个终端之间建立有线连接和无线连接共两种传输通道。例如，用户希望将旧手机中的数据传输给新手机时，可使用相应接口的数据线连接旧手机和新手机以建立USB连接，并可通过Wi-Fi功能建立旧手机和新手机之间的Wi-Fi连接。这样，旧手机可通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至新手机，从而大大提高终端之间的数据传输速度。
并且，由于旧手机和新手机之间具有USB连接和Wi-Fi连接这两种传输通道，因此，当任意一种传输通道中断(例如Wi-Fi连接断开)时，发送端还可继续使用另一传输通道(例如USB连接)传输数据，从而保证了数据传输时的稳定性。

示例性地，图3是一种可以运行在上述终端中的
Figure PCTCN2018087153-appb-000006
操作系统的软件架构示意图。该软件架构可以分为四层，分别为应用程序层，应用程序框架层，函数库层和Linux内核层。
1、应用程序(Applications)层
应用程序层是操作系统的最上一层，包括操作系统的原生应用程序，例如电子邮件客户端、短信、通话、日历、浏览器、联系人等。当然，对于开发者来说，开发者可以编写应用程序并安装到该层。
一般而言，应用程序可以使用Java语言开发，通过调用应用程序框架层所提供的应用程序编程接口(application programming interface，API)来完成。
2、应用程序框架(Application Framework)层
应用程序框架层主要是为开发者提供了可以访问应用程序所使用的各种API，开发者可以通过应用程序框架来与操作系统的底层(例如函数库、Linux内核等)进行交互，开发自己的应用程序。该应用程序框架主要是Android操作系统的一系列的服务和管理系统。应用程序框架主要包括如下基础服务：
活动管理器(Activity Manager)：用来管理应用程序生命周期并提供常用的导航回退功能；
内容提供器(Content Providers)：用来管理不同应用程序间的数据共享和访问；
通知管理器(Notification Manager)：用于控制应用程序在状态栏、锁屏界面等显示提示信息(例如警告(Alerts)、通知(Notifications)等)给用户；
剪贴板管理器(Clipboard Manager):主要提供应用程序内部或者应用程序之间的复制或粘贴功能；
视图(View)：具有丰富的、可扩展的视图集合，可用于构建一个应用程序。它具体包括列表(list)、网格(grid)、文本(text)、按钮(button)，以及图片(image)等多种类型。
位置管理器(Location Manager)：主要是让应用程序可以访问到终端所处的地理位置。
3、函数库(Libraries)层
函数库层是应用程序框架的支撑，是连接应用程序框架层与Linux内核层的重要纽带。函数库层包括一些由计算机程序C语言或C++语言编译的函数库，这些函数库能被操作系统中的不同的组件使用，它们通过应用程序框架层为开发者提供服务。具体地，函数库可以包括libc函数库，它是专门为基于embedded linux的设备定制的；函数库还可以包括多媒体库(Media Framework)，该库支持多种编码格式的音频或视频的回放和录制，同时支持静态图像文件，以及常见的音频或视频编码格式。函数库还包括界面管理库(Surface Manager)，主要负责管理针对显示系统的访问，具体用于在执行多个应用程序时候，负责管理显示与存取操作间的互动，另外也负责2D绘图与3D绘图进行显示合成。
函数库层中还可以包括其他的用于实现手机各个功能的函数库，例如：SGL(Scalable Graphics Library)：基于XML(Extensible Markup Language)文件的2D图形图像处理引擎；SSL(Secure Sockets Layer)：位于TVP/IP协议与各种应用层协议之间，为数据通讯提供支持；OpenGL/ES：3D效果的支持；SQLite：关系型数据库引擎；Webkit：Web浏览器引擎；FreeType：位图及矢量字体支持；等等。
Android Runtime是一种在

操作系统上的运行环境，是
Figure PCTCN2018087153-appb-000008
操作系统所使用的一种新的虚拟机。在Android Runtime中，采用AOT(Ahead-Of-Time)技术，应用程序在第一次安装的时候，该应用程序的字节码就会被预先编译成机器码，让应用程序成为真正的本地应用，之后再次运行，就省去了编译这一步骤，启动和执行都会变得更加快速。
在本申请其它一些实施例中，Android Runtime也可以由核心函数库(Core Libraries)和Dalvik虚拟机(Dalvik Virtual Machine)代替。核心函数库提供了Java语言API中的大多数功能，主要通过Java原生界面(Java native interface，JNI)的方式向应用程序框架层提供调用底层程序库的接口。同时也包含了该操作系统的一些核心API，如android.os、 android.net、android.media等等。Dalvik虚拟机使用一种JIT(Just-in-Time)的运行时编译的机制，每次启动一个进程都需要虚拟机在后台重新编译字节码，会对启动速度有一定的影响。每一个应用程序都运行在是一个Dalvik虚拟机中的实例中，每一个Dalvik虚拟机实例都是一个独立的进程空间。Dalvik虚拟机设计成在一个设备可以高效地运行多个虚拟机。Dalvik虚拟机可执行文件格式是.dex，dex格式是专为Dalvik设计的一种压缩格式，适合内存和处理器速度有限的系统。需要提出的是Dalvik虚拟机依赖于Linux内核提供基本功能(线程、底层内存管理)。可以理解的是，Android Runtime、Dalvik属于不同类型的虚拟机，本领域技术人员可以在不同情况下选用不同形式的虚拟机。
4、Linux内核(Linux Kernel)层
该层提供操作系统的核心系统服务，如安全性、内存管理、进程管理、网络协议栈和驱动模型等都基于Linux内核。Linux内核同时也作为硬件和软件栈之间的抽象层。该层有许多与移动设备相关的驱动程序，主要的驱动有：显示驱动；基于Linux的帧缓冲驱动；作为输入设备的键盘驱动；基于内存技术设备的Flash驱动；照相机驱动；蓝牙驱动；Wi-Fi驱动；USB驱动等。
在本申请实施例中，仍如图3所示，应用程序层安装有一个或多个用于在终端之间传输数据的数据传输应用，例如，手机克隆APP、一键换机APP等。并且，应用程序框架层还包括Wi-Fi管理器(Wi-Fi Manager)和USB管理器(USB Manager)。以手机克隆APP为例，手机克隆APP可以通过调用相应的API与Wi-Fi Manager和USB Manager交互，这样在向用户提供数据传输服务时，可由手机克隆APP作为决策者的角色来控制Wi-Fi Manager和USB Manager，可以实现在Wi-Fi连接和USB连接上同时传输数据的双通道数据传输模式。
当应用程序层中的应用(例如手机克隆APP)需要使用Wi-Fi功能时，可通过Context.getSystemService(Context.WiFi_SERVICE)这一函数来调用应用程序框架层中的Wifi Manager，Wifi Manager又可以通过调用内核层中的Wifi驱动发现和管理其他使用Wi-Fi功能的设备，例如，打开或关闭Wi-Fi功能、扫描Wi-Fi网络，建立Wi-Fi连接等。
当应用程序层中的应用(例如手机克隆APP)需要使用USB功能时，可通过Context.getSystemService(Context.USB_SERVICE)这一函数来调用应用程序框架层中的USB Manager对象，USB Manager又可以通过调用内核层中的USB驱动发现和管理其他USB设备，例如，扫描USB设备、检测USB设备的插拔事件等。
其中，USB Manager在运行时可以有两种工作模式，一个是作为作为主设备时的USBHostManager模式，另一个是作为从设备时的USBDeviceManager模式。当终端(例如手机A)处于USBHostManager模式时，说明此时手机A的角色为USB主设备(host)，手机A可向与其通过USB数据线相连的其他终端(例如手机B)供电，此时，手机B作为USB从设备(slave)运行USBDeviceManager模式。可以理解的是，USBDeviceManager模式和USBHostManager模式是一个相对的概念。以手机为例，当手机通过USB数据线与PC连接时，手机为USBDeviceManager模式，手机作为USB从设备，而当手机通过USB数据线与U盘连接时，手机为USBHostManager模式，手机作为USB主设备。
示例性的，USB Manager可以通过调用函数：public void setCurrentFunction(String function,boolean usbDataUnlocked)在USBDeviceManager模式与USBHostManager模式之间 切换。当切换为USBDeviceManager模式时，USB Manager可执行函数：public ParcelFileDescriptor openAccessory(UsbAccessory accessory)去连接从设备；当切换为USBHostManager模式时，USB Manager可执行函数：public UsbDeviceConnection openDevice(UsbDevice device)去连接并响应主设备发出的指令。
在USB OTG协议之前，USB数据线两端的主从关系一般是确定的，当某一终端与USB数据线上作为USB主设备的接口连接后，触发该终端的USB Manager切换为USBHostManager模式，由该终端扮演USB主设备的角色；当另一终端与USB数据线上作为USB从设备的接口连接后，触发该终端的USB Manager切换为USBDeviceManager模式，由该终端扮演USB从设备的角色。而USB OTG协议中引入了一种主机协商协议(Host Negotiation Protocol，简称HNP)的机制，基于这种机制，USB数据线两端设备在建立USB连接时可协商确定哪一方作为USB主设备，进而由USB主设备向另一方(即USB从设备)供电。因此，在使用支持HNP的USB数据线时均可通过上述协商机制确定USB数据线两端设备的主从关系。
需要说明的是，在USB Type-C规范中也沿用了上述主机协商协议的机制，基于USB Type-C规范确定的USB主设备也可以称为Source设备，即通过VBUS或者VCONN供电的设备，而基于USB Type-C规范确定的USB从设备也可以称为Sink设备，即通过VBUS或者VCONN接受供电的设备。为方便描述，后续实施例中均以USB主设备和USB从设备为例进行说明。
在本申请实施例中，当用户打开手机A中的手机克隆APP，用户打开手机B中的手机克隆APP，手机克隆APP可提示用户与另一传输端(例如手机B)建立Wi-Fi连接和USB连接。进而，手机克隆APP可调用应用程序框架层的Wi-Fi Manager检测并完成与手机B的Wi-Fi连接，手机克隆APP可调用应用程序框架层的USB Manager检测并完成与手机B的USB连接。
那么，以手机A向手机B发送数据为例，手机A可以将用户选中的一部分数据通过上述Wi-Fi连接发送给手机B，并将用户选中的另一部分数据通过上述USB连接发送给手机B。这样的双通道数据传输方法可以显著提高数据的传输速度，并且，当USB连接(或Wi-Fi连接)断开时，手机A还可以通过另一条通道向手机B发送数据，即在数据传输过程中可以实现单通道传输和双通道传输的动态切换，从而提高数据传输过程中的数据稳定性。
为了便于理解，以下结合附图对本申请实施例提供的数据传输方法进行具体介绍。
图4为本申请实施例提供的一种数据传输方法的流程示意图。如图4所示，该数据传输方法可以包括：
S401、第一终端与第二终端建立无线连接。
S402、第一终端与第二终端建立USB连接。
以第一终端为用户的旧手机，第二终端为用户的新手机为例，当用户希望将旧手机中的数据拷贝到新手机上时，用户可分别打开新手机和旧手机上安装的手机克隆APP。
如图5所示，手机克隆APP的首页上显示有设置为旧手机的按钮501以及设置为新手机的按钮502。如图5中的(a)所示，如果检测到用户点击按钮501，则说明此时用户操作的终端为旧手机(即第一终端)，后续可将第一终端作为发送端向与其连接的接收端(即 第二终端)发送数据。如图5中的(b)所示，如果检测到用户点击按钮502，则说明此时用户操作的终端为新手机(即第二终端)，后续可将第二终端作为接收端接收与其连接的发送端(即第一终端)发送的数据。
进一步地，第一终端检测到用户点击按钮501或第二终端检测到用户点击按钮502后，如图6所示，第一终端(或第二终端)可显示在新手机和旧手机之间建立无线连接(例如Wi-Fi连接)的提示601，以及在新手机和旧手机之间建立USB连接的提示602。其中，提示601和提示602还可以是二维码、动画、视频或语音等形式，本申请实施例对此不做任何限制。
那么，根据上述提示601，用户可以打开新手机和旧手机的Wi-Fi功能并接入同一Wi-Fi网络，从而建立新手机和旧手机之间的Wi-Fi连接。或者，用户也可以打开新手机和旧手机的WLAN直连功能，通过WLAN直连功能建立新手机和旧手机之间的Wi-Fi连接。又或者，用户也可以将新手机(或旧手机)设置为个人热点，进而操作另一终端接入该个人热点后建立新手机和旧手机之间的Wi-Fi连接。
示例性的，当第二终端检测到用户点击按钮502后，手机克隆APP可调用Wi-Fi Manager自动建立个人热点，并将该个人热点的名称和密码等信息以二维码等方式显示出来。那么，用户操作第一终端扫描该二维码后即可与第二终端建立Wi-Fi连接。在这种情况下，第一终端和第二终端可以不显示提示601。
又或者，当第一终端检测到用户点击按钮501，第二终端检测到用户点击按钮502后，如果某一终端(例如第一终端)已经开启Wi-Fi功能，并接入某一Wi-Fi网络，由于此时第一终端内的手机克隆APP无法确定当前Wi-Fi连接的另一端是否为准备接收数据的新手机(即第二终端)，因此，手机克隆APP可指示第一终端向当前Wi-Fi连接的另一端发送身份确认消息，例如，询问当前Wi-Fi连接的另一端是否为准备接收数据的新手机。那么，如果第一终端接收到另一端的正确响应，则说明当前第一终端已经与第二终端建立的Wi-Fi连接，此时第一终端和第二终端可以不显示上述提示601。
相应的，根据上述提示602，用户可以使用与新手机和旧手机均适配的USB数据线连接新手机和旧手机，以建立第一终端与第二终端之间的USB连接。例如，新手机和旧手机的USB接口均为USB Type-C类型时，用户可以将C-to-C直连数据线两端的接口分别插入新手机和旧手机的USB接口内。新手机和旧手机检测到这一连接事件后，可基于上述主机协商协议(HNP)确定其中一方为USB主设备，另一方为USB从设备。例如，如果新手机首先检测到旧手机与其通过USB数据线进行连接，则新手机可通知旧手机：新手机为USB主设备，旧手机为USB从设备。当旧手机向新手机发送确认消息确认这一主从关系后，新手机可按照USB主设备模式运行，而旧手机可按照USB从设备模式运行。此时，可由USB主设备(例如新手机)通过USB数据线向USB从设备(例如旧手机)供电。
又或者，如果在第一终端检测到用户点击按钮501，第二终端检测到用户点击按钮502后，某一终端(例如第一终端)已经检测到与其他USB设备连接，由于此时第一终端内的手机克隆APP可能无法确定当前他USB连接的另一端是否为准备接收数据的新手机(即第二终端)，因此，手机克隆APP可指示第一终端向当前他USB连接的另一端发送身份确认消息，例如，询问当前他USB连接的另一端是否为准备接收数据的新手机。那么，如果第一终端接收到另一端的正确响应，则说明当前第一终端已经与第二终端建立的他USB 连接，此时第一终端和第二终端无需显示上述提示602。
第一终端与第二终端建立USB连接之后，第一终端内应用程序框架层中的USBManager可向应用程序层中的手机克隆APP上报USB连接已建立这一事件。同样，第一终端与第二终端建立Wi-Fi连接之后，第一终端内应用程序框架层中的WiFiManager可向应用程序层中的手机克隆APP上报Wi-Fi连接已建立这一事件。那么，手机克隆APP确定当前已建立了两条传输通道后，便可执行下述步骤S402-S404使用这两条传输通道进行数据传输，提高手机克隆时的数据传输速度。
另外，由于第一终端与第二终端建立USB连接之后，作为USB主设备的终端向作为USB从设备的终端供电，因此USB连接两端设备的电量会发生变化。那么，第一终端可获取第二终端的电量情况以及自身的电量情况。或者，可由第二终端获取第一终端的电量情况以及自身的电量情况，本申请实施例对此不做任何限制。其中，第一终端或第二终端可通过已建立的USB连接获取对方的电量情况，也可通过已建立的Wi-Fi连接获取对方的电量情况。
以第一终端获取自身的电量情况举例，手机克隆APP可以预先在应用程序框架层的PowerManager(电源管理器)注册触发PowerManager上报电量的条件，例如，请求PowerManager周期性(例如每5分钟)的上报电量剩余量给手机克隆APP，或者，请求PowerManager在检测到电量每降低10％后向手机克隆APP上报当前的电量剩余量等。那么，PowerManager检测到终端的电量符合手机克隆APP预先注册的条件时，可将当前的电量剩余量上报给手机克隆APP。类似的，第二终端也可以按照上述方法获取自身的电量情况，进而将第二终端的电量情况通过已建立的Wi-Fi连接或USB连接发送给第一终端。
当然，PowerManager也可以向手机克隆APP开放电量查询的接口，手机克隆APP也可以通过调用该接口主动获取当前的电量情况，本申请实施例对此不做任何限制。
需要说明的是，本实施例中是以第一终端与第二终端建立了无线连接和USB连接之后进行数据传输为例说明的。可以理解的是，第一终端还可以在与第二终端建立了无线连接之后便开始进行数据传输，在数据传输的过程中可再建立第一终端与第二终端之间的USB连接。或者，第一终端还可以在与第二终端建立了USB连接之后便开始进行数据传输，在数据传输的过程中可再建立第一终端与第二终端之间的无线连接，后续实施例中将对此进行详细阐述，故此处不再赘述。
可以理解的是，上述S401和S402中，也可以先执行S402，后执行S401。本实施例中对S401和S402步骤的先后顺序不做限定。
S403、第一终端接收用户在第一终端中选中待传输数据的第一输入。
在步骤S403中，当第一终端作为旧手机(即发送端)检测到第一终端与第二终端之间的无线连接和USB连接已经建立后，如图7A所示，在第一终端内运行的手机克隆APP可跳转至界面701。用户可以在界面701中可选择需要向第二终端(即接收端)发送的待传输数据。例如，上述界面701中包括联系人、短信、照片、通话记录、音乐以及应用等候选数据。其中，某一应用作为候选数据时具体可以包括其应用程序本身，还可以包括用户在使用该应用过程中产生的记录数据和储存的文件，例如联系人头像、缓冲和下载好的图片等。那么，用户可以点击界面701中待传输的联系人、短信、照片、通话记录、音乐以及应用中的至少一项选中待传输数据，此时，用户在界面701中的选中候选数据可作为 上述第一输入。
当第一终端检测到用户在界面701中执行选中待传输数据的第一输入后，可进一步确定待传输数据的传输方式。例如，第一终端可将待传输数据中的一部分(例如第一数据)通过上述无线连接传输，将待传输数据中的另一部分(例如第二数据)通过上述USB连接传输。
示例性的，第一终端可基于第一终端与第二终端之间无线连接的网络质量确定上述第一数据的数据量。例如，当第一终端与第二终端之间的Wi-Fi网络速度小于阈值时，可将小部分数据确定为通过Wi-Fi连接的方式传输，将剩余的大部分数据确定为通过USB连接的方式传输，这样可以提高整个待传输数据的传输速度。
又或者，第一终端可基于第一终端和第二终端的电量确定上述第一数据的数据量。例如，当检测到USB数据线连接的某一终端的电量小于20％或者第一终端和第二终端之间的电量差大于60％时，由于终端使用Wi-Fi连接传输数据时的耗电量更大，因此，第一终端可将小部分数据确定为通过Wi-Fi连接的方式传输，将剩余的大部分数据确定为通过USB连接的方式传输，这样可以降低数据传输过程中某一终端的耗电量过大而导致终端关机，使得数据传输中断的几率。
当然，如果检测到第一终端和第二终端之间Wi-Fi连接的网络质量较好而USB连接的传输速度较慢，例如，第一终端和第二终端之间的USB连接是基于传输速度较慢的USB 1.1规范实现的，那么，第一终端可将大部分数据确定为通过Wi-Fi连接的方式传输，将剩余的小部分数据确定为通过USB连接的方式传输，从而提高待传输数据的传输速度。其中，USB 1.1中所支持的最低速度(Low Speed)为1.5Mbits/s，全速(Full Speed)为12Mbits/s，USB 2.0全速时的高速度(High Speed)可达到480Mbits/s，而最新的USB 3.0可支持5Gbits/s的超高速(Super Speed)传输。
在确定Wi-Fi连接和USB连接上传输的具体数据时，第一终端内的手机克隆APP可以将用户选中的待传输数据划分为多个数据块。例如，将1G的待传输数据按照1M的大小划分为1024个数据块，并按照划分时的顺序为每个数据块编号。这样，第一终端可以按照上述实施例中的方法确定通过Wi-Fi连接传输的数据块数目以及通过USB连接传输时的数据块数目。其中，通过Wi-Fi连接传输的数据块可以为第一数据，通过USB连接传输的数据块可以为第二数据。例如，在USB连接速度较快而Wi-Fi连接质量不好时，可通过USB连接传输800个数据块，同时通过Wi-Fi连接传输224个数据块。当然，手机克隆APP也可以基于电量情况、Wi-Fi网速以及USB的传输速度等因素在传输过程中动态的确定每一个数据块的传输方式。后续，第二终端接收到这两种发送方式发送的数据块后可以按照各个数据块的编号恢复上述1G的待传输数据。
另外，上述实施例中均以第一终端(例如第一终端内运行的手机克隆APP)自动确定待传输数据的传输方式为例说明的，在本申请的另一些实施例中，还可以由用户手动选择待传输数据的传输方式。
例如，如图7B中的(a)所示，用户在界面701中每选中一项待传输数据后均可弹出选择框703，使得用户可以在选择框703中选择该项待传输数据是通过Wi-Fi连接传输还是通过USB连接传输。又例如，如图7B中的(b)所示，界面701中包括与Wi-Fi连接对应的区域704以及与USB连接对应的区域705。那么，用户可以将需要传输的每一项待传 输数据拖入相应的区域中，以选择该项待传输数据的传输方式。例如，用户将联系人这一项待传输数据拖入区域704，即指示第一终端通过Wi-Fi连接传输该项待传输数据，此时，用户将联系人这一项待传输数据拖入区域704的操作可以作为上述第一输入。
S404、响应于用户在第一终端上执行的第二输入，第一终端通过上述无线连接和USB连接向第二终端发送上述待传输数据。
在步骤S404中，如果检测到用户在第一终端上执行发送上述待传输数据的第二输入，例如，用户点击上述界面701中的发送按钮702，此时，第一终端作为旧手机(即发送端)可通过已建立的无线连接(例如Wi-Fi连接)向第二终端传输一部分待传输数据(即第一数据)。同时，第一终端还可通过已建立的USB连接向第二终端传输另一部分待传输数据(即第二数据)。这样，第一终端可以通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至新手机，从而大大提高终端之间的数据传输速度。
需要说明的是，发送上述待传输数据的第二输入与上述选中待输入数据的第一输入可以是用户执行的两个独立手势。例如，上述第一输入可以是用户点击界面701中的联系人等候选数据的单击手势，而第二输入是用户点击发送按钮702的单击手势。
或者，上述第二输入与第一输入也可以是用户执行的一个手势中的两个阶段。如图8中的(a)所示，如果检测到用户手指长按联系人801这项待传输数据(即第一输入)，则第一终端可确认用户选中联系人801作为待传输数据，此时，如图8中的(b)所示，如果检测到用户手指没有离开触摸屏，而是继续将联系人801这项待传输数据拖入发送区域802后松开(即第二输入)，则第一终端可确认用户希望发送联系人801这项待传输数据，并执行步骤S404。
可以理解的，续请参阅图8中的(b)，如果检测到用户手指长按联系人801这项待传输数据，在用户手机没有离开触摸屏，而是继续将联系人801这项待传输数据拖入发送区域802(即，用户长按联系人并拖入发送区域未松开可以理解为第一输入)，然后松开(可以理解为第二输入)，则第一终端可确认用户希望发送联系人801这项待传输数据，执行步骤S404。
需要说明的是，上述实施例中均以第一终端和第二终端安装并运行手机克隆APP举例说明的，可以理解的是，第一终端和第二终端也可以将上述数据传输的功能集成在自身的设置功能内。以第一终端为例，如图9中的(a)所示，第一终端的设置界面901中包含数据拷贝902这一选项，当用户打开数据拷贝902这一选项后，如果检测到Wi-Fi连接和USB连接已经建立，则如图9中的(b)所示，第一终端可显示联系人、短信、照片、通话记录、音乐以及应用等至少一项候选数据供用户选择。当用户从这些候选数据中选中了需要传输的待传输数据后，可点击发送按钮903触发第一终端按照上述步骤S404将待传输数据通过Wi-Fi连接和USB连接发送给第二终端。
进一步地，如图10中的(a)所示，在第一终端与第二终端进行数据传输的过程中，如果检测到Wi-Fi连接断开，则第一终端内的Wi-FiManager可向手机克隆APP上报Wi-Fi连接断开这一事件。此时，手机克隆APP可以将上述第一数据的传输方式从通过Wi-Fi连接传输转换为通过USB连接传输。并且，第一终端或第二终端上均可向用户提示Wi-Fi连接已经断开，或者第一终端和第二终端中一个终端向用户提示Wi-Fi连接已经断开。相应的，如图10中的(b)所示，在第一终端与第二终端进行数据传输的过程中，如果检测 到USB连接断开，则第一终端内的USBManager可向手机克隆APP上报Wi-Fi连接断开这一事件。此时，手机克隆APP可以将上述第二数据的传输方式从通过USB连接传输转换为通过Wi-Fi连接传输。并且，第一终端或第二终端均可向用户提示USB连接已经断开，或者第一终端和第二终端中一个终端向用户提示USB连接已经断开。
当然，如果Wi-Fi连接断开后，第一终端与第二终端又重新建立了Wi-Fi连接，或者，USB连接断开后，第一终端与第二终端又重新建立了USB连接，则第一终端可以恢复使用USB连接和Wi-Fi连接这两种传输通道同时传输当前剩余的待传输数据至第二终端，从而实现双传输通道和单传输通道之间的动态切换。
需要说明的是，上述Wi-Fi连接断开或USB连接断开可以是用户手动操作第一终端(或第二终端)断开的。例如，用户关闭Wi-Fi功能或者用户拔掉第一终端与第二终端之间的USB数据线。或者，上述Wi-Fi连接断开或USB连接断开也可以是第一终端(或第二终端)自动断开的。例如，可以在第一终端或第二终端检测到Wi-Fi网络质量较差，或者某一终端的电量较低时自动断开已建立的Wi-Fi连接，本申请实施例对此不做任何限制。
另外，在第一终端与第二终端进行数据传输的过程中，如果第一终端与第二终端之间的电量差大于第一阈值，且电量较低一方为进行供电的USB主设备，则USB主设备如果继续向USB从设备供电的话很可能会耗尽USB主设备的电量并导致数据传输中断。
因此，在本申请提供的实施例中，当USB主设备与USB从设备(即第一终端与第二终端)之间的电量差大于第一阈值，且USB主设备为电量较低的一方时，USB数据线两端的第一终端和第二终端可自动切换当前USB连接的主从关系。即将电量较低的USB主设备切换为接受供电的USB从设备，并将电量较高的USB从设备切换为供电的USB主设备。从而及时对电量较低的一方进行及时补电，避免因一方电量过低而导致传输中断的问题，提高数据传输过程的稳定性。
其中，进行供电的USB主设备可以是第一终端，也可以是第二终端；相应的，当USB主设备是第一终端时，接受供电的USB从设备为第二终端，当USB主设备是第二终端时，接受供电的USB从设备为第一终端。
示例性的，在第一终端与第二终端建立USB连接(即步骤S402)时，第一终端与第二终端之间的主从关系已经确定。例如，第一终端为USB主设备，第二终端为USB从设备。那么，第一终端可以获取第二终端(即USB从设备)的电量情况以及自身的电量情况，例如，第一终端内运行的手机克隆APP可周期性的获取第二终端的电量情况以及自身的电量情况，并计算USB主设备与USB从设备之间的电量差。
如图11中的(a)所示，USB主设备的电量为25％，而USB从设备的电量为80％。此时，USB主设备与USB从设备之间的电量差大于第一阈值(例如50％)。那么，USB主设备内的手机克隆APP可与USB从设备内的手机克隆APP交互，以确认双方准备切换当前的主从关系切换。进而，USB主设备内的手机克隆APP可调用应用程序框架层中的USB Manager，将USB Manager从USBHostManager模式切换为USBDeviceManager模式，此时，如图11中的(b)所示，第一终端从USB主设备切换为USB从设备。另外，USB从设备内的手机克隆APP也可调用应用程序框架层中的USB Manager，将USB Manager从USBDeviceManager模式切换为USBHostManager模式，此时，如图11中的(b)所示，第二终端从USB从设备切换为USB主设备，切换为USB主设备的第二终端向切换为USB 从设备的第一终端供电。
需要说明的是，当第二终端切换为USB主设备，第一终端切换为USB从设备后，虽然USB数据线两端的主从关系进行了切换，但第一终端与第二终端之间的数据传输方向并没有改变，仍然是第一终端向第二终端发送待传输数据。这样在不干扰数据传输的同时，可以实现USB数据线两端设备的电量均衡，避免数据传输时一方电量过低导致的传输中断问题。
在本申请的一些实施例中，第一终端与第二终端之间的USB数据线可以为C-to-C的直连数据线。由于C-to-C的直连数据线支持上述主机协商协议(HNP)所规定的协商机制，因此，当USB主设备与USB从设备之间的电量差大于第一阈值，且USB主设备为电量较低的一方时，USB主设备与USB从设备可基于HNP进行协商，确定USB主设备与USB从设备的切换时机、切换后的角色等协商结果，进而按照该协商结果动态的切换自身的主从关系。
在本申请的另一些实施例中，第一终端与第二终端之间的USB数据线也可以为非C-to-C的直连数据线。例如，第一终端与第二终端之间的USB数据线可以是通过OTG连接器转接后的USB数据线。由于非C-to-C的直连数据线可能不支持上述主机协商协议的机制，因此，当USB主设备与USB从设备之间的电量差大于第一阈值，且USB主设备为电量较低的一方时，USB主设备可向USB从设备发送切换指示，并在接收到USB从设备的响应后自动将与其相连的USB数据线下电，进而将原本运行的USB主设备模式强制切换为USB从设备模式。而原本的USB从设备在接收到USB主设备发送的切换指示后，也可自动将与其相连的USB数据线下电，将原本运行的USB从设备模式强制切换为USB主设备模式。切换后的USB主设备和USB从设备重新对USB数据线上电后可恢复第一终端与第二终端之间的USB连接，实现USB数据线两端设备的主从关系切换。
另外，在USB主设备和USB从设备进行主从关系切换的过程中，可暂停使用USB连接进行数据传输，避免由于主从关系切换而导致数据传输出错的现象。
需要说明的是，上述实施例中均以USB主设备作为执行主体阐述获取USB主设备和USB从设备之间的电量差，并根据该电量差切换自身的主从关系，同时指示USB从设备进行主从关系切换等过程。可以理解的是，也可以由USB从设备作为执行主体获取USB主设备和USB从设备之间的电量差，并根据该电量差切换自身的主从关系，同时指示USB主设备进行主从关系切换，本申请实施例对此不做任何限制。
另外，当第一终端与第二终端建立无线连接(例如Wi-Fi连接)后，Wi-Fi连接的两端设备也可能具有主从关系。例如，如果第一终端打开了个人热点，第二终端可将第一终端作为一个Wi-Fi接入点接入第一终端的个人热点。此时，第一终端可作为Wi-Fi主设备，而第二终端可作为Wi-Fi从设备。又例如，如果第一终端与第二终端之间采用Wi-Fi直连的方式建立Wi-Fi连接，那么，在建立Wi-Fi连接时可基于Wi-Fi直连的相关协议规范，例如802.11z协议，将某一终端(例如第一终端)确定为group owner(即Wi-Fi主设备)，那么，第二终端可作为group client(即Wi-Fi从设备)连接group owner，从而建立第一终端与第二终端之间的Wi-Fi连接。
一般而言，Wi-Fi主设备相比于Wi-Fi从设备在传输数据的过程中耗电量更多。因此，为了避免发生因Wi-Fi主设备在传输数据的过程耗电量过多而导致传输中断的问题，当 Wi-Fi主设备与Wi-Fi从设备之间的电量差大于第二阈值(第二阈值与上述第一阈值可以相同，也可以不同)，且Wi-Fi主设备为电量较低的一方时，第一终端和第二终端可自动切换当前Wi-Fi连接的主从关系。即将当前电量较低的Wi-Fi主设备切换为耗电量较小的Wi-Fi从设备，并将电量较高的Wi-Fi从设备切换为耗电量较大Wi-Fi主设备，从而缓解Wi-Fi主设备耗电过快而导致传输中断的问题。
当然，如果Wi-Fi从设备在传输数据的过程中耗电量更多，则可以在Wi-Fi主设备与Wi-Fi从设备之间的电量差大于第二阈值(第二阈值与上述第一阈值相同或不同)，且Wi-Fi从设备为电量较低的一方时，由第一终端和第二终端自动切换当前Wi-Fi连接的主从关系，从而缓解Wi-Fi从设备耗电过快而导致传输中断的问题。可以由第一终端执行Wi-Fi连接的主从关系切换，当然也可以由第二终端执行Wi-Fi连接的主从关系切换。
也就是说，在本申请实施例中可以基于第一终端与第二终端的电量情况，控制电量较多的一方承担传输过程中更加耗电的角色，从而降低数据传输过程中一方电量耗尽而导致传输中断的几率。
与上述实施例中切换USB连接的主从关系类似的，如图12中的(a)所示，Wi-Fi主设备的电量为32％，而Wi-Fi从设备的电量为80％。此时，Wi-Fi主设备与Wi-Fi从设备之间的电量差大于第二阈值(例如40％)。那么，Wi-Fi主设备内的手机克隆APP可与Wi-Fi从设备内的手机克隆APP交互，以确认双方切换当前Wi-Fi连接的主从关系切换。
进而，Wi-Fi主设备内的手机克隆APP可调用应用程序框架层中的Wi-Fi Manager，由Wi-Fi Manager将当前的运行模式切换为Wi-Fi从设备模式，此时，如图12中的(b)所示，第一终端从Wi-Fi主设备切换为Wi-Fi从设备。另外，Wi-Fi从设备内的手机克隆APP也可调用应用程序框架层中的Wi-Fi Manager，由Wi-Fi Manager将当前的运行模式切换为Wi-Fi主设备模式，此时，如图12中的(b)所示，第二终端从Wi-Fi从设备切换为Wi-Fi主设备。
这样，原本电量较低的Wi-Fi主设备切换为Wi-Fi从设备后，其耗电量可相应降低，进而可降低数据传输过程中一方电量耗尽而导致传输中断的几率。
需要说明的是，上述实施例中均是以第一终端作为Wi-Fi主设备切换为Wi-Fi从设备举例说明的，可以理解的是，也可以由第二终端作为Wi-Fi主设备切换为Wi-Fi从设备，本申请实施例对此不做任何限制。
图13为本申请另一些实施例提供的一种数据传输方法的流程示意图。如图13所示，该数据传输方法可以包括：
S1001、第一终端与第二终端建立USB连接。
其中，第一终端与第二终端建立USB连接的具体方法可参见上述步骤S402的相关描述，此处不再赘述。可以理解的，在S1001之前，可以打开第一终端的手机克隆APP，打开第二终端的手机克隆APP。
S1002、第一终端接收用户在第一终端中选中待传输数据的第一输入。
与上述步骤S403不同的是，第一终端可以在检测到USB连接已经建立后，可将USB连接已经建立的消息上报第一终端内运行的手机克隆APP，手机克隆APP无需在确认Wi-Fi连接已建立的情况下便可触发手机克隆APP跳转至图7A或图7B所示的界面701。进而，第一终端可接收用户在界面701选中待传输数据的第一输入。当然，也可以基于第 一终端的设置界面901中包含数据拷贝902这一选项，当用户打开数据拷贝902这一选项后，如图9中的(b)所示，第一终端可显示联系人、短信、照片、通话记录、音乐以及应用等至少一项候选数据供用户选择，用户从这些候选数据中选中需要传输的待传输数据可以为第一输入。
S1003、响应于用户在第一终端上执行的第二输入，第一终端通过USB连接向第二终端发送上述待传输数据。
在步骤S1003中，如果检测到用户在第一终端上执行发送上述待传输数据的第二输入，例如，用户点击上述界面701中的发送按钮702，此时，由于第一终端与第二终端之间目前只有通过USB连接的传输通道，因此，第一终端可通过该USB连接向第二终端发送用户选中的待传输数据。由于USB连接的稳定性以及数据传输速度较高，因此，相比于通过Wi-Fi连接向第二终端发送上述待传输数据，通过USB连接向第二终端发送待传输数据的速度和稳定性更高。
S1004(可选的)、第一终端与第二终端建立无线连接。例如，第一终端与第二终端建立Wi-Fi连接。
S1005(可选的)、第一终端通过USB连接和无线连接向第二终端发送待传输数据。
以Wi-Fi连接作为无线连接举例，在执行上述步骤S1001-S1003的过程中，第一终端也可以检测是否与第二终端建立Wi-Fi连接，或者，第二终端也可以检测是否与第一终端建立Wi-Fi连接。
那么，如果在执行步骤S1003之前，即在第一终端通过USB连接发送上述待传输数据之前，检测到第一终端与第二终端建立了无线连接，则按照上述步骤S404，可由第一终端作为发送端通过已建立的Wi-Fi连接向第二终端传输一部分待传输数据(即第一数据)。同时，第一终端还可通过已建立的USB连接向第二终端传输另一部分待传输数据(即第二数据)。这样，第一终端可以通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至第二终端，从而大大提高终端之间的数据传输速度。
相应的，如果在执行步骤S1003的过程中，即在第一终端通过USB连接发送上述待传输数据的过程中，检测到第一终端与第二终端建立了无线连接。此时，如图14所示，第一终端(或第二终端)可提示用户是否同时启用Wi-Fi连接和USB连接传输。那么，如果检测到用户点击确定按钮1101，则第一终端可以将当前剩余的待传输数据划分为两部分，一部分继续通过上述USB连接发送给第二终端，另一部分可通过新建立的Wi-Fi连接发送给第二终端，实现数据传输过程中双传输通道和单传输通道之间的动态切换。
可选的，在检测到用户点击确定按钮1101，第一终端也可以将当前剩余的待传输数据通过无线连接，例如通过Wi-Fi连接，发送给第二终端。第一终端可以不通过USB连接传输待传输的数据给第二终端。
当然，如果在第一终端通过USB连接发送上述待传输数据的过程中，检测到第一终端与第二终端建立了无线连接，第一终端也可在用户无感知的情况下，默认采用双传输通道的方式向第二终端发送未发送的上述待传输数据，本申请实施例对此不做任何限制。
另外，在第一终端向第二终端发送待传输数据的过程中，当USB主设备与USB从设备之间的电量差大于第一阈值，且USB主设备为电量较低的一方时，USB数据线两端的第一终端和第二终端可切换当前USB连接的主从关系，从而及时对电量较低的一方进行补 电，避免因一方电量过低而导致传输中断的问题，提高数据传输过程的稳定性。
类似的，在第一终端向第二终端发送待传输数据的过程中，当Wi-Fi主设备与Wi-Fi从设备之间的电量差大于第二阈值，且Wi-Fi主设备为电量较低的一方时，第一终端和第二终端也可切换当前Wi-Fi连接的主从关系，从而缓解Wi-Fi主设备耗电过快而导致传输中断的问题。
其中，切换当前USB连接的主从关系，以及切换当前Wi-Fi连接的主从关系的具体方法可参见上述步骤S404中的相关描述，此处不再赘述。
需要说明的是，上述实施例中判断第一终端和第二终端的电量差是否满足主从关系切换条件时使用的第一阈值和第二阈值可以是本领域技术人员根据实际经验或实际应用场景设置的，也可以是第一终端或第二终端基于一定算法在数据传输过程中动态调整的，本申请实施例对此不做任何限制。
示例性的，以设置第一阈值的取值为例，由于第一终端和第二终端内的电量总和是一定的，那么，为了保证能够完成本次数据传输，第一终端(或第二终端)可以根据待传输数据的数据量以及当前USB连接和Wi-Fi连接的传输速度预估完成本次数据传输所需的预估电量。这样，基于该预估电量，第一终端(或第二终端)可动态设置第一阈值的取值，以保证完成本次数据传输后第一终端和第二终端的电量均不为零。
另外，由于用户使用手机克隆APP拷贝数据的目的是为了尽快使用新手机，且一般新手机的电量较低，因此，还可以适当减小第一阈值的取值，使得作为旧手机的第一终端可以尽快向新手机(第二终端)供电，保证完成本次数据传输后第二终端的电量大于第一终端的电量。
至此，上述步骤S1001-S1005阐述了第一终端先与第二终端建立无线连接，在基于该无线连接传输数据的同时，如果第一终端与第二终端又建立了USB连接，则第一终端通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至第二终端的数据传输场景。
相应的，在本申请的另一些实施例中，第一终端也可先与第二终端建立USB连接，在基于该USB连接传输数据的同时，如果第一终端与第二终端又建立了无线连接，则第一终端仍然可以通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至第二终端。此时，如图15所示，该数据传输方法可以包括：
S1201、第一终端与第二终端建立无线连接。例如，第一终端与第二终端建立Wi-Fi连接。
可以理解的，在第一终端与第二终端建立无线连接之前，可以打开第一终端的手机克隆APP，打开第二终端的手机克隆APP。
S1202、第一终端接收用户在第一终端中选中待传输数据的第一输入。
S1203、响应于用户在第一终端上执行的第二输入，第一终端通过无线连接向第二终端发送上述待传输数据。
与上述步骤S1001-S1003对应的，在步骤S1201-S1203中，如果用户打开了第一终端和第二终端的Wi-Fi功能并操作这两个终端建立了第一终端与第二终端之间的无线连接，则作为数据发送端的第一终端可以跳转至手机克隆APP的界面701，接收用户在界面701选中待传输数据的第一输入。进而，如果检测到用户点击上述界面701中的发送按钮702(即第二输入)，由于第一终端与第二终端之间目前只有通过Wi-Fi连接的传输通道，因此， 第一终端可通过该Wi-Fi连接向第二终端发送用户选中的待传输数据。
S1204(可选的)、第一终端与第二终端建立USB连接。
S1205(可选的)、第一终端通过USB连接和无线连接向第二终端发送未发送的上述待传输数据。
与上述步骤S1004-S1005对应的，如果在第一终端通过Wi-Fi连接发送上述待传输数据之前，检测到第一终端与第二终端建立了USB连接，则可按照上述步骤S404，由第一终端作为发送端通过Wi-Fi连接向第二终端传输一部分待传输数据(即第一数据)。同时，第一终端还可通过USB连接向第二终端传输另一部分待传输数据(即第二数据)。这样，第一终端可以通过USB连接和Wi-Fi连接这两种传输通道同时传输数据至第二终端，从而大大提高终端之间的数据传输速度。
相应的，如果在第一终端通过Wi-Fi连接发送上述待传输数据的过程中，检测到第一终端与第二终端建立了USB连接。此时，如图16所示，第一终端(或第二终端)可提示用户是否同时启用USB连接和无线连接进行数据传输。那么，如果检测到用户点击确定按钮1301，则第一终端可以将当前剩余的待传输数据划分为两部分，一部分继续通过上述USB连接发送给第二终端，另一部分可通过新建立的Wi-Fi连接发送给第二终端，实现数据传输过程中双传输通道和单传输通道之间的动态切换。
可选的，在第一终端与第二终端建立了USB连接，在检测到用户点击确定按钮1301，第一终端可以将当前剩余的待传输数据通过USB连接，发送给第二终端。第一终端可以不通过Wi-Fi连接传输待传输的数据给第二终端。
当然，在第一终端向第二终端发送待传输数据的过程中，也可以按照上述步骤S404的相关描述切换当前USB连接的主从关系，或者切换当前Wi-Fi连接的主从关系，本申请实施例对此不做任何限制。
