具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在本文中提及的“多个”是指两个或两个以上。“和/或”，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。字符“/”一般表示前后关联对象是一种“或”的关系。
相关技术中，可穿戴式设备中设置有单一处理器，并通过运行在处理器上的操作系统，对设备运行过程中产生的所有系统事件进行处理，因此该处理器需要具备较强的数据处理能力，并在设备运行过程中保持工作状态。然而，在日常使用过程中，可穿戴式设备在大多数情况下只需要实现一些对处理性能要求较低的功能，比如，对于智能手表或智能手环来说，大多数情况下，智能手表或智能手环只需要进行时间显示和消息提示。因此，长时间保持处理器处于工作状态并不会提高可穿戴式设备的性能，反而会增加设备功耗，导致可穿戴式设备的续航时间较短。
为了在保证可穿戴式设备性能的同时，降低可穿戴式设备的功耗，在一种可能的实施方式中，可穿戴式设备至少设置具有不同处理性能以及功耗的第一处理器和第二处理器，分别用于运行第一系统和第二系统(即双核双系统)，并为双核双系统设计了一套系统切换机制。
可穿戴式设备运行过程中，通过运行在低功耗处理器上的第一系统，对低性能处理需求的事件进行处理，并保持高功耗处理器处于休眠状态(相应的，由高功耗处理器运行的第二系统处于休眠状态)，在实现可穿戴式设备基础功能的同时，降低了可穿戴式设备的功耗；当出现存在高性能处理需求的事件时(比如启动应用程序时)，通过唤醒高功耗处理器，并切换至第二系统对事件进行处理，保证触发的事件能够被及时响应并处理，满足可穿戴式设备的性能需求。
并且，由于高功耗处理器从休眠状态切换为唤醒状态需要耗费一定时间(至少需要200ms至300ms)，因此为了降低启动应用过程中应用画面的显示延迟，本申请引入了启动效果预展示机制，在高功耗处理器切换至唤醒状态之前，由低功耗处理器运行的第一系统绘制并展示应用界面；当高功耗处理器切换至唤醒状态时，再由高功耗处理器运行的第二系统展示应用画面并运行应用，实现应用启动效果的预展示，从而提升视觉上应用的启动速度，降低系统切换过程中应用画面的显示延迟。
本申请实施例中，由于第一处理器和第二处理器异步工作，且第一系统和第二系统需要实现系统通信(或称为双核通信)。在一种可能的应用场景下，第一系统为运行在微控制单元(Micro Controller Unit，MCU)上的实时操作系统(Real Time Operating System，RTOS)，且第二系统为运行在中央处理器(Central Processing Unit，CPU)上的安卓(Android)操作系统。
如图1所示，其示出了本申请一个示例性实施例示出的安卓操作系统的双核通信软件框架。该双核通信软件框架遵循“低耦合，高可靠，高复用”的设计原则，包括Kernel(内核)、HIDL(硬件抽象层接口描述语言)、Native Service(本地服务)、Framework Service(框架服务)、Framework API(框架接口)和APP(应用)部分的模块开发。
其中，APP模块包括Launcher(桌面启动器)、Setting(设置)和SystemUI(系统用户界面)等功能模块；Framework API模块中包括MCUManager(MCU管理)、SensorManager(传感器管理)、LocationManager(位置管理)等管理模块，Framework Service模块中包括MCUManagerService(MCU管理服务)、SystemSensorManager(系统传感器管理)、LocationManagerService(位置管理服务)等服务模块，Native Service模块包括dccservice(dcc服务)、Sensorservice(传感器服务)等服务模块，HIDL模块包括Sensor HAL(传感器硬件抽象层)、GPS HAL(全球定位系统硬件抽象层)等模块。Kernel模块包括dcc_datah、dcc_data、Mcu_sensor、Mcu_gps、Mcu_factory等DCC Transfer Driver(DCC传输驱动)。
传输层作为双核通信软件框架中衔接上下层的接口层，向应用层屏蔽系统下层(数据链路层)通信的传输细节，为应用场景提供服务通道；应用层作为服务提供的主体，响应于人机交互并通过传输层对人机交互过程中产生的数据进行传输，以及对外部数据请求进行响应。
RTOS采用对等原则进行设计。以可穿戴式设备为智能手表为例，如图2所示，其示出了本申请一个示例性实施例示出的RTOS的双核通信软件框架。
RTOS的双核通信软件框架分为应用层(Application Layer)、服务层(Service Layer)、框架层(Framework Layer)、硬件抽象层(Hardware abstraction layer)和平台层(Platform Layer)。
其中，应用层包括watch face(表盘)、Daily Tracker(日常追踪)、Message center(消息中心)、Voice around Apps(声音应用)、Health Apps(健康应用)、Settings(设置)等应用模块；服务层包括Sport&health  task(运动健康任务)、System manager task(系统管理任务)、AMS(活动管理服务)、AudioService(音频服务)、Log Service(日志服务)、OFTP Service(Odette文件传输协议服务)、BT Service(蓝牙服务)、Delegate Service(转交服务)、RPC Service(远程调用服务)、sensor Service(传感器服务)、storage Service(存储服务)等服务模块；框架层包括Message Pub(消息中心)、UI Framework(用户界面框架)、G2D Engine(G2D殷勤)、Audio Middleware(音频中间件)、Preference(偏好)、File system(文件系统)、Algorithms(算法)、Aios、AsycEvent(进程内异步事件)等框架模块；硬件抽象层包括Screen/TP(屏幕/触控屏)、Audio(音频)、GPS(全球定位系统)、sensors(传感器)、Keypad(键盘)、Motor(马达)等硬件抽象模块；平台层包括板级支持包(Board Support Package，BSP)以及低等级驱动(LOW level Driver)，其中，BSP包括Screen/TP、Keys(按键)、GPS、Codec(编码译码器)、sensors、Flash(闪存)、Motor、PSRAM(伪静态随机存储器)等等，低等级驱动包括Uart(通用异步收发传输器)、ADC(模数转换器)、GPIO(通用输入输出)、SPI(串行外设接口)、I2C(集成电路总线)、IOS(输入输出系统)、PCM(脉冲编码调制)、I2S(集成音频总线)、HWTimer(硬件定时器)。
需要说明的是，上述双核通信软件框架仅用于示意性说明，本领域技术人员还可以根据实际需求，对上述框架进行增加、删除或修改，本申请实施例并不对双核通信软件框架的具体结构构成限定。
请参考图3，其示出了本申请一个示例性实施例提供的应用界面的显示方法的流程图，本实施例以该方法应用可穿戴式设备，且可穿戴式设备支持运行第一系统和第二系统为例进行说明，该方法可以包括如下步骤。
步骤301，在第一系统处于唤醒状态，且第二系统处于休眠状态的情况下，响应于目标应用的应用启动指令，通过第一系统绘制并显示目标应用的界面。
在一种可能的实施方式中，可穿戴式设备设置有第一处理器和第二处理器，其中，第一处理器的处理性能低于第二处理器的处理性能(第一处理器的处理能力和处理速度均低于第二处理器)，且第一处理器的功耗低于第二处理器的功耗。相应的，第二系统(由第二处理器运行)能够处理第一系统(由第一处理器运行)所处理的事件，而第一系统并不一定能够处理第二系统所处理的事件。
在另一种可能的实施方式中，可穿戴式设备也可以设置单一处理器，第一系统和第二系统分别运行在处理器的不同核心上，其中，运行第二系统的核心的处理性能高于运行第一系统的核心的处理性能。
比如，以可穿戴式设备为智能手表为例，第一处理器为MCU，第二处理器为CPU，第一系统为RTOS，第二系统为安卓系统。相应的，第一系统所能处理的事件包括表盘显示、表盘界面切换、通知消息显示等对处理性能要求较低的场景或弱交互场景；第二系统所能处理的事件包括来电接听、启动应用、表盘编辑、功能设置等对处理性能要求较高的场景或强交互场景。
在一种可能的实施方式中，可穿戴式设备的工作模式包括能模式、混动模式和低功耗模式，其中，性能模式下，第二处理器和第一处理器均保持唤醒状态(相应的，第一系统和第二系统均处于唤醒状态)；低功耗模式下，仅第一处理器保持唤醒状态，而第二处理器保持关闭状态(即第一系统处于唤醒状态，第二系统处于关闭状态)；混动模式下，在通过第一系统处理事件时，第二处理器处于待机状态，可以在休眠和唤醒状态之间切换(即第一系统处于唤醒状态时，第二系统既可以处于唤醒状态，又可以处于休眠状态)。
可选的，唤醒状态下，系统相关数据缓存在内存(RAM)中，以便于随时运行系统相关数据，休眠状态下，处理器大部分硬件模块关闭，系统相关数据存储在硬盘(ROM)中，并在切换为唤醒状态时由硬盘写入内存中。
不同于智能手机一类具有强交互属性的电子设备，可穿戴式设备作为一种辅助性的电子设备，在绝大多数使用场景下与用户之间仅存在弱交互。比如，用户在大部分场景下仅通过智能手表进行抬腕查看时间或消息提示。因此，可穿戴式设备通过第一系统对事件进行处理时，控制第二处理器处于休眠状态(第二系统处于休眠状态)，从而降低可穿戴式设备的整体功耗。
在第一系统处于唤醒状态，且第二系统处于休眠状态的情况下，当接收到目标应用的应用启动指令时，表明需要启动并运行目标应用，由于第一系统并不具备运行目标应用的能力，因此需要唤醒处于休眠状态的第二系统，从而通过第二系统启动并运行目标应用。
然而，由于第二系统的唤醒过程需要花费一定时间(至少需要200ms至300ms)，因此触发启动目标应用后会出现短暂无响应现象(表现为需要等待一段时间才会出现应用画面)，影响使用体验。本申请实施例中，为了降低系统切换过程中应用画面的显示延迟，当可穿戴式设备在第一系统运行过程中接收到目标应用的应用启动指令，首先通过第一系统绘制目标应用的界面并进行显示(仅负责绘制界面图像，并非在第一系统处启动或运行目标应用)。
可选的，该应用启动指令为通过快捷键(比如物理按键)触发的指令或者通过第一系统中微件(widget)触发的指令；目标应用可以为健康监测应用、即时通信应用、计时应用、闹钟应用、运动应用等等，且该 目标应用的界面可以为静态画面(比如首帧应用界面)，也可以是动态画面(比如应用启动过程的启动动画)。本申请实施例并不对应用启动指令的触发方式、目标应用的类型以及界面的类型进行限定。
由于第一系统处于唤醒状态，因此第一系统在接收到应用启动指令后可以立即进行界面绘制显示，即触发启动目标应用后立即显示目标应用的界面，从而提升视觉上应用的启动速度。
示意性的，如图4所示，以可穿戴式设备为智能手表为例，智能手表中设置有RTOS(由第一处理器运行)和安卓系统(由第二处理器运行)。第一处理器处于唤醒状态，而第二处理器处于休眠状态时，智能手表通过RTOS显示表盘41，安卓系统处于休眠状态，从而保持较低的功耗。当用户需要通过运动应用查看运动数据时，可以通过双击物理按键的方式快速启动运动应用。接收到运动应用的启动指令后，RTOS绘制运动应用的应用界面42并进行显示。
步骤302，响应于第二系统由休眠状态切换为唤醒状态，通过第二系统绘制目标应用的界面。
在一种可能的实施方式中，第一系统绘制显示界面的过程中，第二系统进行同步唤醒，即第二处理器由休眠状态切换为唤醒状态。当第二系统切换至唤醒状态后，通过第二系统启动并运行目标应用。其中，在启动目标应用过程中，第二系统同样需要进行目标应用的界面绘制。
可选的，第二系统所绘制目标应用的界面与第一系统所绘制目标应用的界面相同，比如，两者均绘制目标应用启动后的首帧应用界面；或者，第二系统所绘制目标应用的界面与第一系统所绘制目标应用的界面不同，比如，第一系统所绘制的界面为应用启动过程中的过渡动画，而第二系统所绘制的界面为过渡动画播放完毕后的首帧应用界面。当然，第一系统和第二系统还可以绘制其他属于目标应用的界面，本实施例并不对两者绘制的具体界面进行限定。
可选的，第一处理器采用向第二处理器发送中断的方式唤醒第二处理器。
步骤303，响应于第二系统完成界面绘制，通过第二系统显示目标应用的界面并运行目标应用。
第二系统完成界面绘制后，可穿戴式设备运行的系统即由第一系统切换为第二系统，从而通过第二系统对目标应用的界面进行显示，并继续运行目标应用。
可选的，切换至第二系统后，第一系统仍旧在后续处于唤醒状态(低功耗，对续航影响较小)，或者第一系统切换为休眠状态，本实施例对此不作限定。
示意性的，如图4所示，RTOS显示应用界面42的过程中，安卓系统由休眠状态切换为唤醒状态，当安卓系统唤醒后(比如经过200ms)，智能手表运行的系统由RTOS切换为安卓系统，并通过安卓系统显示应用界面42，运行运动应用。
可选的，第二系统完成事件处理后(比如退出目标应用返回表盘)，第二处理器重新切换至休眠状态，并切换回第一系统处理事件，使可穿戴式设备在少部分场景下保持高性能(但是高功耗)，而在大多数场景下保持低功耗(但低性能)，进一步降低可穿戴式设备的功耗，延长可穿戴式设备的续航时间。
综上所述，本申请实施例中，对于支持双系统的可穿戴式设备，若在第一系统处于运行状态而第二系统处于休眠状态的情况下，接收到目标应用的应用启动指令，首先由第一系统绘制并显示目标应用的界面，并在第二系统唤醒后，通过第二系统显示目标应用的界面并运行目标应用；采用本申请实施例提供的方案，通过第一系统预展示应用启动效果，能够提升视觉上应用的启动速度，降低系统切换过程中应用画面的显示延迟。

响应于更新方式为删除，且第一存储空间中存储有第二应用信息，且存在待删除启动方式以外的启动方式使用第二应用信息，确定存在更新冲突；
其中，存在更新冲突的情况下，第一存储空间中的第二界面资源不更新。

方法还包括：

可选的，可穿戴式设备设置有第一处理器和第二处理器，第二处理器的功耗高于第一处理器的功耗，且第一系统是由第一处理器运行的系统，第二系统是由第二处理器运行的系统。
在一种可能的实施方式中，第一系统和第二系统各自对应有数据存储空间，且由于第一系统仅负责处理简单事件，而第二系统则需要处理复杂事件，因此第二系统对应的存储空间远大于第一系统对应的存储空间。为了实现通过第一系统绘制显示界面，第一系统对应的存储空间中存储应用对应的界面资源，接收到应用启动指令后，第一系统即基于存储空间中的界面资源进行应用界面绘制。下面采用示例性的实施例进行说明。
请参考图5，其示出了本申请另一个示例性实施例提供的应用界面的显示方法的流程图，本实施例以该方法应用可穿戴式设备为例进行说明，该方法可以包括如下步骤。
步骤501，在第一系统处于唤醒状态，且第二系统处于休眠状态的情况下，响应于目标应用的应用启动指令，通过第一系统从第一存储空间获取目标应用对应的目标界面资源，第一存储空间为第一系统对应的存储空间。
本申请实施例中，第一系统对应有第一存储空间，第一存储空间中存储有至少一个应用对应的界面资 源，该界面资源指绘制应用界面所需的资源，该界面资源可以包括文字资源、图片资源、动画资源、特效资源、界面布局资源等等，本实施例对界面资源中包含的具体内容不做限定。
在一种可能的实施方式中，第一存储空间中存储有第二系统中各个应用对应的界面资源。比如，当第二系统中安装有运动应用、健康监测应用、闹钟应用以及即时通信应用时，第一存储空间中即存储安装有4个应用各自对应的界面资源。
由于第一存储空间有限，且并非第二系统下的所有应用均支持从第一系统启动(即目标应用为支持在第一系统下启动的应用)，因此在另一种可能的实施方式中，第一存储空间用于存储支持在第一系统下启动的应用对应的界面资源，从而在实现无感系统切换的同时，降低界面资源占用的存储空间。
可选的，支持在第一系统下启动的应用指：能够在第二系统处于休眠状态的情况下启动的应用。比如，当第一系统中设置有应用的启动入口时，该应用则属于支持在第一系统下启动的应用，和/或，当应用被设置为可以通过快捷键启动时，该应用属于支持在第一系统下启动的应用。
在一些实施例中，在第一系统下启动应用的方式包括如下至少一种：通过快捷键启动和通过第一系统的widget启动。
其中，通过快捷键在第一系统下启动应用的方式可以由用户自行设置，比如设置双击物理按键启动特定应用，或者长按物理按键启动特定应用；widget可以由用户自行添加在第一系统中，比如在表盘上添加健康监测应用对应的widget，以便用户点击第一系统中显示的widget启动健康监测应用。
比如，当第二系统中安装有运动应用、健康监测应用、闹钟应用以及即时通信应用时，由于运动应用支持通过双击物理按键启动，且健康监测应用支持通过表盘上的widget触发，因此第一存储空间仅存储运动应用以及健康监测应用对应的界面资源，无需存储闹钟应用以及即时通信应用对应的界面资源。
关于获取目标应用对应目标界面资源的具体方式，在一种可能的实施方式中，第一存储空间中的应用信息与界面资源关联存储，即存储应用信息与界面资源之间的映射关系。
可选的，该应用信息包括应用包名(packagename)和应用类名(activityname)中的至少一种。其中，当应用仅具有单一功能界面时，该应用信息中包含应用包名，当应用具有多个功能界面，且可以通过设置在第一系统下启动并显示特定功能界面时，该应用信息中包含应用包名和(特定功能界面对应的)应用类名。
相应的，接收到目标应用的应用启动指令后，即通过第一系统获取目标应用对应的目标应用信息，从而基于目标应用信息，通过第一系统从第一存储空间中获取目标界面资源，其中，目标应用信息包括目标应用包名和目标应用类名中的至少一种。
在一些实施例中，第一系统基于目标应用信息在第一存储空间中查找与目标应用信息匹配的界面资源，并将查找到的界面资源确定为目标应用对应的目标界面资源。
在一个示意性的例子中，第一存储空间中应用信息与界面资源之间的映射关系如表一所示。
表一
应用信息 界面资源
应用包名：sport_app 界面资源文件A
应用包名：health_app 界面资源文件B
当获取到目标应用的应用包名为sport_app时，第一系统将第一存储空间中的界面资源文件A确定为目标界面资源；当获取到目标应用的应用包名为health_app时，第一系统将第一存储空间中的界面资源文件B确定为目标界面资源。
步骤502，基于目标界面资源，通过第一系统绘制并显示目标应用的界面。
进一步的，获取到目标界面资源后，第一系统立即进行界面的实时绘制及显示。
可选的，第一系统进行界面绘制过程中，除了需要利用到目标界面资源外，还可能需要利用到其他数据，比如时间数据，传感器数据(比如计步器数据)等等，从而保证绘制出的界面中内容的准确性。
在一个示例性的例子中，第一系统获取到运动应用对应的目标界面资源中包含图片资源、文字资源以及界面布局资源，第一系统根据界面布局资源指示的界面元素布局方式，将图片资源以及文字资源绘制在对应的界面位置，并将当前时间以及计步器数据渲染在界面中，得到运动应用的应用界面。
步骤503，响应于第二系统由休眠状态切换为唤醒状态，通过第二系统绘制目标应用的界面。
本步骤的实施方式可以参考步骤302，本实施例在此不再赘述。
步骤504，响应于第二系统完成界面绘制，通过第二系统向第一系统发送切换指令，切换指令用于指示第一系统转移图形用户界面(Graphical User Interface，GUI)的展示权限。
为了保证目标应用的正常使用，系统切换过程中，第一系统需要将图形用户界面的展示权限转移给第二系统，以便目标应用运行过程中可穿戴式设备展示第二系统的图形用户界面。在一种可能的实施方式中 第二系统完成界面绘制后，向第一系统发送切换指令，指示第一系统向第二系统转移图形用户界面的展示权限。
步骤505，响应于第二系统获取到图形用户界面的展示权限，通过第二系统显示目标应用的界面并运行目标应用。
第二系统获取到图形用户界面的展示权限后，显示绘制完成的目标应用的界面并运行目标应用，相应的，可穿戴式设备即展示目标应用的界面。
本实施例中，通过在第一存储空间中存储应用信息与界面资源，使得第一系统接收到应用启动指令后，能够基于目标应用的目标应用信息从第一存储空间中准确获取对应的目标界面资源，有助于提高界面的绘制速度和绘制准确性。
并且，第一存储空间仅对支持在第一系统下启动的应用的界面资源进行存储，在实现系统无感切换的前提下，减少界面资源占用的存储空间，降低对第一存储空间容量的需求。
上述实施例中，由于可穿戴式设备中应用的界面并非保持不变，且支持在第一系统下启动的应用也可能会发生变化，因此为了保证应用启动过程中显示的应用界面的准确性，第一存储空间中存储的界面资源也需要相应更新。在一种可能的实施方式中，在第二系统处于唤醒状态的情况下，可穿戴式设备通过第二系统向第一系统发送界面资源更新消息(存在界面资源更新事件时)，第一系统即基于界面资源更新消息，更新第一存储空间中存储的界面资源。其中，该界面资源更新消息中至少包括待更新应用的应用信息。
以第一系统为MCU运行的RTOS，第二系统为CPU运行的安卓系统为例，如图6所示，当应用层(Application)中存在界面资源更新事件(包括语言更新、widget更新、快捷键更新等事件)时，应用层将更新后的界面资源预置到安卓系统对应的框架(Framework)资源安卓应用程序包(Android application Package，APK)中。
框架层中设置的界面资源管理中控负责监听界面资源更新事件，当监听到界面资源更新事件时，界面资源管理中控即从框架资源APK中获取界面资源，并通过内核层中设置的双核通信模块(具体设置在内核层的DCC)与MCU进行通信，以便MCU基于接收到界面资源更新数据对第一存储空间中存储的界面资源进行更新。
针对不同的更新场景，第二系统与第一系统之间通过交互实现界面资源更新的过程也不同。其中，当存在系统级的界面资源更新事件时，第一系统需要对第一存储空间内存储的所有界面资源进行更新；当存在应用级的界面资源更新事件时，第一系统则只需要对特定应用的界面资源进行更新。下面分别采用实施例对不同更新场景下的界面资源更新过程进行说明。
请参考图7，其示出了本申请一个示例性实施例提供的界面资源更新过程的流程图，本实施例以该方法应用可穿戴式设备为例进行说明，该方法可以包括如下步骤。
步骤701，在第二系统处于唤醒状态的情况下，响应于接收到语言更新广播，通过第二系统获取第一应用的第一应用信息，其中，第一存储空间中存储有第一应用对应的第一界面资源。
在一种可能的实施方式中，当可穿戴式设备的系统语言发生变更时，第二系统会接收到语言更新广播，该语言更新广播中包含切换后的系统语言。比如，当用户将可穿戴式设备的系统语言由中文切换为英文时，第二系统接收到指示切换为英文的语言更新广播。
由于系统语言发生变更时，第二系统中应用的应用语言均需要发生变更，相应的，应用界面中包含的内容(比如文字内容)也会发生相应变化，因此接收到语言更新广播后，第二系统确定需要对所有应用的界面资源进行更新，并获取第一存储空间中第一应用的第一应用信息。
关于获取第一应用信息的方式，在一种可能的实施方式中，由于第一存储空间中存储有第一应用信息与第一界面资源之间的映射关系，因此第二系统可以通过第一系统获取第一应用信息。可选的，本步骤可以包括如下步骤：
一、通过第二系统向第一系统发送查询消息。
可选的，第二系统通过内核层的双核通信模块，向第一系统发送查询消息，请求第一系统查询第一存储空间中存储的第一应用信息。相应的，第一系统接收到查询消息后，即从第一存储空间中获取存储的第一应用信息。
示意性的，如图8所示，安卓系统在唤醒状态下接收到语言更新广播(ACTION_LOCALE_CHANGED)时，向RTOS发送查询消息。
二、通过第一系统向第二系统发送第一应用的第一应用信息，并删除第一存储空间中第一应用对应的第一界面资源。
可选的，第一系统查询到各个第一应用的第一应用信息后，通过内核层的双核通信模块向第二系统发送包含第一应用信息的查询结果。
结合上述实施例中表一所示的数据，第一系统向第二系统反馈的查询结果中包含应用包名sport_app 以及health_app。
由于系统语言更新后，原先存储的界面资源无效，因此为了释放第一存储空间，并保证后续界面资源更新的准确性，在一种可能的实施方式中，第一系统将删除第一存储空间中第一应用对应的第一界面资源。
可选的，第二系统发送的查询消息中包含预设标识，当识别出查询消息中包含该预设标识时，第一系统确定因系统语言变化需要更新界面资源，从而删除第一存储空间中存储的第一界面资源。结合上述实施例中表一所示的数据，第一系统删除第一存储空间中存储的界面资源文件A和界面资源文件B。
示意性的，如8所示，RTOS向安卓系统反馈查询结果的同时，删除第一存储空间中存储的第一界面资源。
步骤702，通过第二系统向第一系统发送第一界面资源更新消息，第一界面资源更新消息中包含第一应用信息以及更新后的第一界面资源。
在一种可能的实施方式中，第二系统基于第一应用信息，从第二存储空间中获取存储的第一应用对应的更新后的第一界面资源，其中，第二存储空间为第二系统对应的存储空间，且更新后的第一界面资源由各个第一应用存储至第二存储空间。比如，第二系统中的界面资源管理中控从框架资源APK中获取更新后的第一界面资源。
结合上述步骤中的示例，第二系统基于应用包名sport_app以及health_app，获取更新后的界面资源文件A’和界面资源文件B’。
可选的，更新后的第一界面资源中包含的文字资源与更新前第一界面资源中包含的文字资源不同。比如，更新后的文字资源为第一应用的英文名，更新前的文字资源为第一应用的中文名。
进一步的，第二系统通过双核通信模块向第一系统发送第一界面资源更新消息，以便第一系统对第一存储空间进行界面资源更新。
在一种可能的实施方式中，第一界面资源更新消息中可以包含如下字段中：
1、path：用于表征更新路径，本实施例中，path字段的值表征系统语言更新触发界面资源更新；
2、action：用于表征界面资源的更新方式，本实施例中，action字段的值表征替换界面资源；
3、packagename：应用包名；
4、data：更新后的界面资源；
5、extra：用于表征是否强制更新界面资源，本实施例中，extra字段的值表征强制更新界面资源。
需要说明的是，第一界面资源更新消息中还可以包括其他字段，本实施例仅以包含上述字段为例进行示意性说明，但并不对此构成限定。
示意性的，如图8所示，安卓系统接收到查询结果后，基于查询结果获取更新后的第一界面资源，并基于第一界面资源向RTOS发送第一界面资源更新消息。
步骤703，通过第一系统，将第一应用信息与更新后的第一界面资源关联存储在第一存储空间。
接收到第一界面资源更新消息后，第一系统即将第一应用信息与更新后的第一界面资源进行关联存储，后续系统切换过程中，第一系统即可基于更新后的界面资源进行应用界面绘制和显示，保证显示的应用界面所采用的语言与系统语言一致。
结合上述步骤的示例，第一系统基于第一界面资源更新消息进行界面资源更新后，第一存储空间中应用信息与界面资源之间的映射关系如表二所示。
表二
应用信息 界面资源
应用包名：sport_app 界面资源文件A’
应用包名：health_app 界面资源文件B’
可选的，完成界面资源更新后，第一系统向第二系统那个更新完成通知，告知第二系统已完成对界面资源的更新。若第二系统在预设时长内未接收到更新完成通知，则重新向第一系统发送第一界面资源更新消息。
示意性的，如图8所示，RTOS更新完第一界面资源后，向安卓系统发送更新完成通知。
除了采用从第一系统处获取第一应用信息这一方式外，在另一种可能的实施方式中，由于各个应用都会将更新后的界面资源存储在第二系统(的第二存储空间)中，因此可穿戴式设备还可以通过第二系统从第二存储空间中获取第一应用的第一应用信息，并在向第一系统发送的第一界面资源更新消息中设置强制更新标识。
相应的，第一系统识别出第一界面资源更新消息中包含强制更新标识时(比如通过第一界面更新消息中的extra字段设置)，即删除第一存储空间中存储的界面资源，并将第一应用信息与更新后的第一界面资源关联存储在第一存储空间，避免存储同一应用的两套界面资源。
本实施例中，在系统语言更新时，通过第二系统获取各个第一应用的第一应用信息，并基于第一应用 信息获取更新后的第一界面资源，从而将更新后的第一界面资源发送至第一系统，由第一系统对第一存储空间中存储的第一界面资源进行更新，确保后续进行系统切换时，第一系统显示的应用界面的语言与系统语言保持一致。
请参考图9，其示出了本申请另一个示例性实施例提供的界面资源更新过程的流程图，本实施例以该方法应用可穿戴式设备为例进行说明，该方法可以包括如下步骤。
步骤901，在第二系统处于唤醒状态的情况下，响应于监听到第二应用的启动方式更新消息，通过第二系统获取第二应用的第二应用信息以及第二界面资源，启动方式更新消息用于表征第二应用的启动方式发生变化。
为了提高应用的启动效率，用户可能会为第二系统中的应用设置快捷启动方式，从而在第一系统下也能够启动第二系统中的应用。其中，设置快捷启动方式可以包括在第一系统中添加应用的widget，以及设置启动应用的快捷键。
相应的，当第二应用的启动方式发生更新(比如添加快捷启动方式或者删除快捷启动方式)时，第一系统需要对第一存储空间中的界面资源进行适应性更新。
在一种可能的实施方式中，当第二系统中第二应用的启动方式发生变化时，第二系统监听到启动方式变更消息，该启动方式变更消息中可以包括目标启动方式以及目标启动方式对应的更新方式。
比如，当为第二应用设置通过widget启动时，该目标启动方式为widget启动，且更新方式为增加；当为第二应用删除通过快捷键启动时，该目标启动方式为快捷键启动，且更新方式为删除。
进一步的，第二系统获取第二应用对应的第二应用信息以及第二界面资源。其中，第二系统可以根据启动方式更新消息中第二应用的应用信息，从第二存储空间中获取第二界面资源。
可选的，当启动方式更新消息指示的更新方式为增加时，第二系统获取第二应用信息以及第二界面资源，而当启动方式更新消息指示的更新方式为删除时，第二系统仅需获取第二应用信息。
示意性的，如图10所示，安卓系统监听到到第二应用的启动方式更新消息(包括ACTION_SHORTC UT_SETTING_CHANGED以及ACTION_WIDGET_CHANGED)时，获取第二应用的第二界面资源。
步骤902，通过第二系统向第一系统发送第二界面资源更新消息，第二界面资源更新消息中包含更新方式、第二应用信息以及第二界面资源。
基于获取到的第二界面资源，第二系统通过双核通信模块向第一系统发送第二界面资源更新消息，该第二界面资源更新消息除了包含第二应用信息和第二界面资源外，还包含目标启动方式以及更新方式。
在一种可能的实施方式中，第二界面资源更新消息中可以包含如下字段中：
1、path：用于表征更新路径，本实施例中，path字段的值表征更新快捷启动方式(包括更新widget以及更新快捷键)触发界面资源更新；
2、action：用于表征界面资源的更新方式，本实施例中，action字段的值表征增加界面资源或删除界面资源；
3、packagename：应用包名；
4、activityname：应用类名，用于指示应用中的特定应用界面；
5、data：更新后的界面资源；
6、extra：用于表征是否强制更新界面资源。
需要说明的是，第二界面资源更新消息中还可以包括其他字段，本实施例仅以包含上述字段为例进行示意性说明，但并不对此构成限定。
示意性的，如图10所示，安卓系统获取到第二界面资源后，向RTOS发送第二界面资源更新消息，指示RTOS更新第一存储空间中存储的界面资源。
步骤903，基于更新方式通过第一系统更新第一存储空间中第二应用信息对应的第二界面资源。
在一种可能的实施方式中，第一系统基于获取到第二界面资源更新消息，对第一存储空间中第二应用信息对应的第二界面资源进行更新。
关于界面资源更新的具体方式，在一些实施例中，当更新方式为增加时，可穿戴式设备通过第一系统将第二应用信息与第二界面资源关联存储在第一存储空间；当更新方式为删除时，可穿戴式设备通过第一系统从第一存储空间中删除第二应用信息以及第二界面资源。
在一种可能的应用场景下，当第一存储空间中存储有第二应用的第二界面资源时，若直接基于第二界面资源更新消息进行界面资源更新，可能会造成更新冲突。
比如，当第一存储空间中存储有第二应用的第二界面资源时，若第二界面资源更新消息指示增加第二应用的第二界面资源(可以对应不同的快捷启动方式)，直接向第一存储空间中添加第二界面资源会造成界面资源重复存储，导致存储空间浪费。
又比如，当第一存储空间中存储有第二应用的第二界面资源，且第二应用支持通过至少两种不同快捷 方式启动时，若第二界面资源更新消息指示删除第二应用的第二界面资源(删除其中一种快捷启动方式)，直接删除第一存储空间中的第二界面资源会造成只能通过其他快捷启动方式启动第二应用，第一系统无法绘制并显示应用界面。
因此，在一种可能的实施方式中，第一系统接收到第二界面资源更新消息后，基于更新方式以及第二应用信息，进行更新冲突检测，若不存在更新冲突，则基于第二界面资源更新消息指示的更新方式对第一存储空间中的界面资源进行更新；若存在冲突，则不响应第二界面资源更新消息。
针对检测是否存在更新冲突的具体方式，在一种可能的实施方式中，当更新方式为增加(第二界面资源)时，第一系统检测第一存储空间中是否存在第二应用信息，若不存在，则确定不存在更新下冲突，从而将第二应用信息与第二界面资源关联存储在第一存储空间。
在一个示意性的例子中，当第一存储空间中应用信息与界面资源之间的映射关系如表一所示时，若第二界面资源更新消息中包含的更新方式为增加，且包含的第二应用信息为“应用包名：alarm_app”(闹钟应用)时，由于第一存储空间中不包含该第二应用信息，从而确定不存在更新冲突，并进行界面资源更新，界面资源更新后，第一存储空间中应用信息与界面资源之间的映射关系如表三所示。
表三
应用信息 界面资源
应用包名：sport_app 界面资源文件A
应用包名：health_app 界面资源文件B
应用包名：alarm_app 界面资源文件C
可选的，响应于更新方式为增加，且第一存储空间中存储有第二应用信息，第一系统确定存在更新冲突，并不对第一存储空间中的第二界面资源进行更新。
可选的，更新方式为增加时，若确定存在更新冲突，第一系统为第二应用信息添加对应的待添加启动方式。
比如，结合表三所示的数据，当若第二界面资源更新消息中包含的更新方式为增加，且包含的第二应用信息为“应用包名：sport_app”时，由于第一存储空间中包含该第二应用信息，从而确定存在更新冲突，并不对界面资源文件A进行更新，仅为sport_app增加第二界面资源更新消息中的目标启动方式“快捷键”。
在另一种可能的实施方式中，当更新方式为删除(第二界面资源)时，第一系统基于第二界面资源更新消息中的目标启动方式(即待删除启动方式)，检测第一存储空间存储的第二应用信息是否被除待删除启动方式以外的启动方式所使用，若不存在(即第二应用仅采用待删除启动方式所指示的快捷方式启动)，第一系统确定不存在更新冲突，从而从第一存储空间中删除第二应用信息以及第二界面资源。
在一个示意性的例子中，当第一存储空间中应用信息、界面资源以及启动方式之间的映射关系如表四所示。
表四
应用信息 界面资源 启动方式
应用包名：sport_app 界面资源文件A widget、快捷键
应用包名：health_app 界面资源文件B 快捷键
若第二界面资源更新消息中包含的更新方式为删除，且包含的第二应用信息为“应用包名：health_app”，待删除启动方式为“快捷键”时，第一系统确定不存在更新冲突，并进行界面资源更新，界面资源更新后，第一存储空间中应用信息界面资源以及启动方式之间的映射关系如表五所示。
表五
应用信息 界面资源 启动方式
应用包名：sport_app 界面资源文件A widget、快捷键
可选的，响应于更新方式为删除，且第一存储空间中存储有第二应用信息，且存在待删除启动方式以外的启动方式使用第二应用信息，第一系统确定存在更新冲突，并不对第一存储空间中的第二界面资源进行更新。
可选的，更新方式为删除时，若确定存在更新冲突，第一系统为第二应用信息删除对应的待删除启动方式。
比如，结合表四所示的数据，当若第二界面资源更新消息中包含的更新方式为删除，且包含的第二应用信息为“应用包名：health_app”时，由于第一存储空间中包含该第二应用信息，从而确定存在更新冲突，并不对界面资源文件A进行更新，仅为health_app删除第二界面资源更新消息中的待删除启动方式“快捷键”。
在一种可能的实施方式中，第二系统可以通过在第二界面资源更新消息中设置强制更新标识，指示对 第二界面资源进行强制更新。
可选的，响应于识别出第二界面资源更新消息中不包含强制更新标识，第一系统则基于更新方式以及第二应用信息进行更新冲突检测；
响应于识别出第二界面资源更新消息中包含强制更新标识，第一系统则基于更新方式通过第一系统更新第一存储空间中第二应用信息对应的第二界面资源。
可选的，完成界面资源更新后，第一系统向第二系统那个更新完成通知，告知第二系统已完成对界面资源的更新。若第二系统在预设时长内未接收到更新完成通知，则重新向第一系统发送第二界面资源更新消息。
示意性的，如图10所示，RTOS接收到第二界面资源更新消息后，若其中包含强制更新标识，RTOS系统则直接进行界面资源更新(增加或删除)，若其中不包含强制更新标识，RTOS系统则有条件(即不存在更新冲突时)进行界面资源更新(增加或删除)，并在更新完第二界面资源后，向安卓系统发送更新完成通知。
本实施例中，当第二应用的启动方式发生更新时，通过第二系统获取第二应用的第二应用信息，并基于第二应用信息获取第二界面资源，从而向第一系统发送第二界面资源更新消息，由第一系统确定是否第二界面资源是否存在更新冲突，在不存在更新冲突的情况下更新第二界面资源，在存在更新冲突的情况下不更新第二界面资源，保证启动方式更新后系统无感切换功能的正常运行。
需要说明的是，上述各个实施例中，仅以双核双系统设备下应用界面的显示过程为例进行说明，在其他可能的应用场景下，单核双系统(比如处理器不同核心上运行不同系统)设备也可以采用本申请实施例提供的方案实现系统切换过程中应用界面的显示，本实施例在此不作赘述。
