Description

一种折叠屏显示应用方法及电子设备
本申请要求于2019年08月30日提交国家知识产权局、申请号为201910817212.1发明名称为“一种折叠屏显示应用方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子技术领域，尤其涉及一种折叠屏显示应用的方法及电子设备。
背景技术
目前，用户在电子设备上操作应用程序时，应用程序中会存在一些等待场景。例如，手机游戏中的匹配玩伴的过程，需要用户等待一定时间，才能加入游戏战队。又例如，手机中安装的视频应用，在视频应用播放视频之前会先播放一段时间的广告，需要等待广告播放完之后才开始播放视频。
对于有些用户来说，这些等待时间太长会导致用户想要切换其他应用，当用户切换其他应用之后，再次切换回该应用时，可能会发现还是需要重新等待。例如，若用户在游戏应用的等待场景切换手机应用，该游戏应用将被直接暂停，当该游戏应用被切换到前台时，需要从之前切出的时间点继续等待或者需要与服务器重新连接，导致用户在等待场景下的时间利用率较低，用户体验不佳。
发明内容
本申请实施例提供一种折叠屏显示应用方法及电子设备，可以在用户使用该电子设备的过程中，提高用户在应用等待场景中的时间利用率，提升用户体验。

具体实施方式
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。
以电子设备安装有安卓(Android)系统为例，电子设备在运行应用程序时，电子设备系统将尽可能的长时间保持应用进程。在电子设备使用的过程中，当一个应用被用户退出后并不会立刻被系统查杀kill，而是在Android系统内存不足时，为了新建进程，或者为系统运行更重要的进程，或者确保系统的流畅度，系统才会按照优先级杀掉一些进程来回收内存。Android系统可能会根据不同应用程序的进程对用户的相对重 要程度，决定杀掉哪一个进程，或者，Android系统还可能根据电子设备中的应用白名单，决定杀掉哪个应用的进程。后台保活是指进程可以在后台一直运行下去保持不被杀死的状态。例如：微信应用在后台运行时，仍然可以接收其他电子设备发送的消息，就是在后台运行时，如果系统内存不足，可以将微信应用中的其他进程kill，仅保活接收消息的进程。可以理解的，保持进程保活的方法是系统不查杀该进程，即系统通知执行查杀操作的服务程序跳过目标进程。因此，应用程序在后台运行时，后台保活该应用程序并不等于该应用程序在后台运行的状态与在前台运行的状态一致，而是保证该应用的某些进程不被系统查杀。
一个具体的应用中，当电子设备运行的应用为视频应用时，在视频播放的过程中，若检测到用户退出视频应用的操作，该视频应用将被电子设备切换至后台运行。当用户再次切换回该视频应用时，电子设备不能直接显示该视频应用上次播放中断的视频，而是显示视频应用的一个界面。这种方式并不能保证应用在后台继续运行。特别是，当一个应用中当前的场景为等待场景时，如视频应用中的广告播放时间、片头视频播放时间或片尾视频播放时间，或者游戏应用中等待玩家加入的场景等，在等待场景中用户可以切换至电子设备中的其他应用，当用户再次切换回该应用，还是需要在等待场景中继续等待，后台保活仅能保证该应用不会被杀掉，并不能保证该应用在后台继续运行。
对于包括折叠屏的电子设备，应用切换的方式与非折叠屏的电子设备相似，这种应用切换方式并不能发挥折叠屏电子设备的特点。以及，现有的后台保活方式并不能真正保证应用在后台继续运行。用户在使用包括折叠屏的电子设备时，应该提高用户在应用的等待场景中的时间利用率，以及为用户提供更好的体验。
因此，本申请实施例提供一种折叠屏显示应用方法，该方法可以应用于包括折叠屏的电子设备，在电子设备的使用过程中，电子设备处于展开状态和折叠状态时，电子设备显示不同的应用的界面。其中，电子设备处于展开状态时，折叠屏显示第一应用的界面。电子设备由展开状态转变为折叠状态时，电子设备显示第二应用的界面或主界面，电子设备可以在后台继续运行第一应用。其中，第一应用在后台运行的状态与前台运行的状态一致。电子设备由折叠状态转变为展开状态时，电子设备再次显示第一应用的显示界面。使得应用以后台保活方式运行时，能够真正保证应用运行状态与前台运行状态一致，提高用户体验。
本申请实施例中包括折叠屏的电子设备可以分为两类：一类为折叠屏朝外翻折的电子设备，另一类为折叠屏朝内翻折的电子设备。该电子设备可折叠使得折叠屏形成多个显示区域，例如，该电子设备可沿折叠屏边或折叠轴折叠形成第一屏和第二屏。
例如，图1为本申请实施例提供的一种朝外翻折的电子设备的产品形态示意图，图1中(a)是朝外翻折的电子设备100完全展开时的形态示意图。电子设备100可沿折叠边按照图1中(a)所示的方向翻折，形成图1中(b)所示的第一屏和第二屏，电子设备100继续沿折叠边折叠，可形成图1中(c)所示完全被折叠后的电子设备100的形态示意图，电子设备100被完全折叠后第一屏和第二屏相背对。电子设备处于折叠状态时，第一屏或第二屏可以作为主屏显示。
可以理解的是，当电子设备处于折叠状态时，可以在第一屏或第二屏显示界面； 当电子设备处于展开状态时，可以在第一屏和第二屏显示界面。其中，对电子设备的展开状态和折叠状态的介绍可以参考以下实施例中的描述，此处不予说明。

值得一提的是，对于朝外翻折的电子设备，电子设备处于折叠状态时，第一屏或第二屏可以作为主屏。对于朝内翻折的电子设备，电子设备处于折叠状态时，第一屏和第二屏对用户不可见，第三屏作为主屏。
一般而言，包括折叠屏的电子设备(包括朝外翻折的电子设备和朝内翻折的电子设备)的第一屏和第二屏的夹角α的取值范围为[0°，180°]。本申请实施例中，如果α∈[0°，P]，可以确定电子设备处于折叠状态；如果α∈(P，180°]，可以确定电子设备处于展开状态。或者，如果α∈[0°，P)，可以确定电子设备处于折叠状态；如果α∈[P，180°]，可以确定电子设备处于展开状态。其中，P是预设角度阈值。P可以是根据大量用户使用折叠屏的使用习惯确定的；或者，P可以由用户在电子设备中设定。
在一些实施例中，按照大多数用户的使用习惯，第一屏和第二屏的夹角α大于90°时，用户想要将第一屏和第二屏作为整体(即作为一个完整的显示屏)使用的可能性较高。因此，本申请实施例中的预设角度阈值P可以大于90°。其中，预设角度阈值P的取值范围可以为(90°，180°)。例如，预设角度阈值P可以为100°、120°、135°、140°、145°或150°等。
需要说明的是，本申请实施例中的电子设备(包括朝内翻折的电子设备和朝外翻折的电子设备)被折叠后形成的至少两个屏，可以为独立存在的多个屏，也可以为一体结构的一个完整屏，只是被折叠形成了至少两部分。

需要注意的是，本申请实施例中，电子设备包括折叠屏，电子设备被折叠后使得折叠屏分为多个显示区域，每个显示区域称为一个屏。每个屏上可以包括陀螺仪传感器180B，用于测量对应屏的朝向(即朝向的方向向量)。例如，如图1中(b)所示，电子设备被折叠后形成第一屏和第二屏，第一屏和第二屏中均设置有陀螺仪传感器180B，可以分别测量第一屏和第二屏的朝向。电子设备根据测量得到的每个屏的朝向角度变化，确定出第一屏和第二屏的夹角。
例如，电子设备100被折叠形成图4A所示的第一屏(图示A屏)和第二屏(图示B屏)，A屏中设置有陀螺仪传感器A，B屏设置有陀螺仪传感器B。本申请实施例这里，对陀螺仪传感器A测量A屏的朝向(即朝向的方向向量)，陀螺仪传感器B测量B屏的朝向(即朝向的方向向量)的原理，以及电子设备100根据A屏的朝向和B屏的朝向计算A屏和B屏的夹角α的原理进行说明。
其中，陀螺仪传感器的坐标系是地理坐标系。如图4B所示，地理坐标系的原点O位于运载体(即包含陀螺仪传感器的设备，如电子设备100)所在的点，x轴沿当地纬线指向东(E)，y轴沿当地子午线线指向北(N)，z轴沿当地地理垂线指向上，并与x轴和y轴构成右手直角坐标系。其中，x轴与y轴构成的平面即为当地水平面，y轴与z轴构成的平面即为当地子午面。因此，可以理解的是，陀螺仪传感器的坐标系是：以陀螺仪传感器为原点O，沿当地纬线指向东为x轴，沿当地子午线线指向北为y轴，沿当地地理垂线指向上(即地理垂线的反方向)为z轴。
电子设备100利用每个屏中设置的陀螺仪传感器180B，便可测量得到每个屏在其设置 的陀螺仪传感器的坐标系中的朝向的方向向量。例如，参考如图4A所示的电子设备的侧视图，电子设备测量得到的A屏在陀螺仪传感器A的坐标系中的朝向的方向向量为向量z1，B屏在陀螺仪传感器B的坐标系中的朝向的方向向量为向量z2。电子设备100利用公式(1)：
Figure PCTCN2020109313-appb-000001
便可计算出向量z1与向量z2的夹角θ。
又根据图4A可知，由于向量z1与A屏垂直，向量z2与B屏垂直，因此，可以得到A屏与B屏的夹角α＝180°-θ。即电子设备根据测量得到的A屏在陀螺仪传感器A的坐标系中的朝向的方向向量(即向量z1)和B屏在陀螺仪传感器B的坐标系中的朝向的方向向量(即向量z2)，便可确定出A屏与B屏的夹角α。
需要说明的是，虽然A屏和B屏中设置的陀螺仪传感器的位置并不重叠，即A屏和B平的陀螺仪传感器的坐标系的原点并不重叠，但是，两个坐标系的x轴、y轴、z轴是平行的，从而可以认为A屏和B屏中设置的陀螺仪传感器的坐标系是平行的。这样一来，虽然向量z1和向量z2不在同一个坐标系，但是因为两个坐标系的各轴平行，因此，仍可通过上述公式(1)计算向量z1与向量z2的夹角θ。
在一些实施例中，还可以由其他一个或多个传感器配合，测量A屏与B屏的夹角α。例如，折叠屏的每个屏中均可设置一个加速度传感器180E。电子设备100(如处理器110)可利用加速度传感器测量每个屏被转动时的运动加速度；然后根据测量得到的运动加速度计算一个屏相对于另一个屏转动的角度，即A屏与B屏的夹角α。

视图系统在构建界面(比如，包括应用图标的桌面)时，可以通过内容提供器来获取存储的数据文件，并根据获取的数据文件显示界面。在一些实施例中，在构建界面时，还可以对内容提供器中存放的数据文件进行修改。
内核层是硬件和软件之间的层。内核层至少包含显示驱动，摄像头驱动，音频驱动，传感器驱动。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)，摄像头驱动，音频驱动以及传感器驱动等。
其中，用户对电子设备进行输入操作(如展开电子设备的操作)，内核层可以根据输入操作产生响应的输入事件(如折叠屏展开事件)并向应用程序框架层上报该事件。由应用程序框架层的活动管理服务器AMS设置界面显示(包括主界面的显示方式和窗口显示模式等)。应用程序框架层的窗口管理服务器WMS根据AMS的设置绘制界面，然后将界面数据发送给内核层的显示驱动，由显示驱动在折叠屏显示对应的界面。
其中，本申请实施例提供的显示方案基于google的自由窗口(freeform)特性和多窗口多任务基础架构实现。本申请实施例提供的显示流程可以参见图5。如图5所示，在本申请实施例中，活动管理器AMS可以包括Activity原生管理模块和Activity扩展模块。其中，Activity原生管理模块用于负责管理Activity，负责系统中各组件的启动、切换、调度及应用程序的管理和调度等工作。Activity扩展模块用于根据折叠屏所处的折叠状态或展开状态，设置主界面的显示方式和窗口显示模式等。
可以理解的是，在电子设备100显示界面的过程中，电子设备100的折叠屏可能会发生由折叠状态向展开状态的切换，或由展开状态向折叠状态的切换。此时，驱动层的折叠驱动(输入/输出设备驱动)即可以检测到用户输入的折叠事件。本申请实施例中，折叠事件可以是用户控制折叠屏由上述折叠状态转变为展开状态的操作触发的，称为折叠事件1。或者，折叠事件可以是用户控制折叠屏由展开状态转变为折叠状态的操作触发的，称为折叠事件2。折叠驱动可以向框架层(即应用程序框架层)的窗 口管理器WMS上报折叠事件。
窗口管理器WMS可以监听折叠事件，监听到折叠事件后可以确定切换显示屏(display)大小。窗口管理器WMS向活动管理器AMS发送display变化事件，由活动管理器AMS设置窗口模式和窗口的属性。其中，窗口管理器WMS监听到折叠事件1时，可以确定display变大，向活动管理器AMS发送display变化事件1。display变化事件1用于触发活动管理器AMS将窗口模式由全屏模式切换为多窗口模式或单窗口模式，并调整窗口的属性。视图系统获取内容提供器中的数据，确定显示的应用界面，活动管理器获取视图系统中的显示界面，显示第一应用的界面。窗口管理器WMS监听到折叠事件2时，可以确定display变小，向活动管理器AMS发送display变化事件2。display变化事件2用于触发活动管理器AMS将窗口模式由多窗口模式或单窗口模式切换为全屏模式，并调整窗口的属性。视图系统获取内容提供器中的数据，确定显示的应用界面，活动管理器获取视图系统中的显示界面，显示第二应用的界面。
示例性的，若第一应用为游戏应用，电子设备处于展开状态，折叠屏显示第一应用的显示界面。如图6中(a)表示第一应用为游戏应用时，匹配游戏好友的界面。电子设备由展开状态转变为折叠状态，电子设备显示第二应用的界面。如图6中(b)表示第一应用为“微信”的显示界面。经过预设时间之后，如20秒，电子设备由折叠状态转变为展开状态，电子设备显示第一应用的界面。如图6中(c)表示电子设备由折叠状态转变为展开状态，电子设备显示第一应用的显示界面。
例如，电子设备处于展开状态，折叠屏显示第一应用的界面。响应于上述display变化事件2，活动管理器AMS请求窗口管理器WMS绘制窗口，并调用显示驱动显示的界面可以为：电子设备处于折叠状态，折叠屏被分为多个显示区域，在电子设备处于折叠状态的主屏上显示第二应用的界面或主界面。响应于上述display变化事件1，活动管理器AMS请求窗口管理器WMS绘制窗口，并调用显示驱动显示的界面可以为：电子设备的折叠屏处于展开状态，在折叠屏上显示第一应用的界面。
以下将以电子设备为手机，对本申请中折叠屏显示应用方法进行说明，以手机为朝外翻折的手机为例。其中，朝外翻折的手机处于折叠状态时，第一屏或第二屏可以作为主屏。该方法流程如图7所示，包括步骤701-步骤703：
步骤701：手机处于展开状态时，在折叠屏显示第一界面。
其中，第一界面为第一应用的显示界面。示例性的，第一应用可以是手机中的任一个应用程序。例如，第一应用可以是视频应用、游戏应用、短信应用或者即时通信应用(如，微信)等。其中，手机在前台运行第一应用时，可以是第一应用的显示界面。
步骤702：响应于手机从展开状态转变为折叠状态，在手机的主屏显示第二界面，手机在后台继续运行第一应用。
其中，第二界面是第二应用的显示界面或者第二界面是手机的主界面。手机的主界面可以包括多个应用图标。
示例性的，第二应用可以是手机在后台运行的一个应用；或者，第二应用是手机在预设时间内运行次数或者运行时长大于预设阈值的任一个应用；或者，第二应用是手机中预先配置的应用。
例如，在预设时间内，手机统计每个应用被运行次数或每个应用的运行时长，若手机应用中“微信”、“微博”和“QQ”被运行次数都超过预设阈值，手机可以选择其中任一个应用作为第二应用。
需要注意的是，本申请实施例中，手机在后台运行第一应用时，第一应用在后台运行的状态与前台运行的状态一致。
本申请实施例对，响应于手机从展开状态转变为折叠状态，手机在后台继续运行第一应用的具体方法进行说明。
示例性的，第一应用在后台运行的状态与前台运行的状态一致是指，手机处于展开状态时，若第一应用中的第一界面为游戏玩家匹配场景，如图6中(a)所示游戏应用中为手机用户匹配其他游戏玩家的场景，该场景中设置有倒计时601，响应于手机由展开状态转变为折叠状态，第一应用在后台运行时，第一应用的倒计时时长不会被暂停，而是可以像其在前台运行的状态一样继续倒计时。例如，手机处于展开状态时，第一应用的倒计时的剩余等待时长为20秒。手机响应于由展开状态转变为折叠状态，第一应用被切换至后台继续运行，手机主屏显示第二应用的界面。第二应用在前台运行10秒之后，手机由折叠状态转变为展开状态，手机显示第一应用，第一应用的倒计时的剩余等待时长为10秒。即第一应用在后台运行时，第一应用的倒计时图标中的剩余等待时长不会停止，而是可以继续在后台倒计时。
需要说明的是，Android系统中Activity的生命周期可以包括：1)启动Activity时，系统会先调用onCreate方法，然后调用onStart方法，最后调用onResume，Activity进入运行状态。2)当前Activity被其他Activity覆盖其上或被锁屏时，系统会调用onPause方法，暂停当前Activity的执行。3)当前Activity由被覆盖状态回到前台或解锁屏时，系统会调用onResume方法，再次进入运行状态。4)当前Activity转到新的Activity界面或按Home键回到主屏，自身退居后台时，系统会先调用onPause方法，然后调用onStop方法，进入停滞状态。5)用户后退回到此Activity时，系统会先调用onRestart方法，然后调用onStart方法，最后调用onResume方法，再次进入运行状态。6)当前Activity处于被覆盖状态或者后台不可见状态，即2)和4)，系统内存不足，杀死当前Activity，而后用户退回当前Activity时，再次调用onCreate方法、onStart方法、onResume方法，进入运行状态。7)用户退出当前Activity时，系统先调用onPause方法，然后调用onStop方法，最后调用onDestory方法，结束当前Activity。
结合Android系统中Activity的生命周期可知，手机在前台运行第一应用时，手机响应于由展开状态转变为折叠状态，手机在主屏显示第二应用的界面，手机将第一应用切换至后台运行，此处属于上述生命周期中的4)，系统会调用onPause()接口，系统调用onPause()接口后，第一应用将被暂停。即手机在前台运行第二应用时，第一应用在后台暂停运行。可以理解的，第一应用在后台暂停运行时，第一应用的倒计时图标中的剩余等待时长也将暂停，而不会在后台继续倒计时。
因此，本申请实施例中手机按照前台运行的状态在后台继续运行第一应用，具体是指：手机在后台运行第一应用时，第一界面中的等待信息中的等待时间继续倒计时。
手机可以通过以下两种实现方式，实现按照前台运行的状态在后台继续运行第一应用。
实现方式(1)：响应于手机从展开状态转变为折叠状态，手机拦截向第一应用传输的暂停PAUSE命令。
第一应用在后台运行时，手机拦截向第一应用传输的暂停PAUSE命令，以使得第一应用在后台运行的状态与前台运行的状态一致。例如，手机不调用onPause()接口。即第一应用在后台运行时，系统不调用onPause()接口，第一应用将不会收到系统发送的PAUSE命令，因此第一应用可以在后台继续运行，第一应用的剩余等待时长不会被暂停，可以在后台继续倒计时。
实现方式(2)：第一应用在后台运行时，手机向第一应用传输第二指令，该第二指令用于指示第一应用继续按照前台运行的状态运行。
示例性的，第一应用在后台运行时，手机可以调用onPause()接口，并通过onPause()接口传输第二指令，指示第一应用继续按照前台运行的状态运行。例如，第一应用在后台运行时，手机可以调用onPause()接口，并通过onPause()接口传输第二指令，此时第一应用可以按照其在前台运行的状态一样，继续在后台运行。例如，第一应用的剩余等待时长可以按照在前台运行的状态一样继续在后台倒计时。该实现方式中，手机通过onPause()接口传输继续运行指令时，需要修改第一应用的运行逻辑。
步骤703：响应于手机由折叠状态转变为展开状态，手机显示第一界面。
可以理解的是，手机由展开状态转变为折叠状态时，第一应用在后台继续运行，手机主屏显示第二应用。第二应用运行预设时间之后，手机由折叠状态转变为展开状态，手机显示第一界面，第一应用也在后台运行预设时间，第一界面是第一应用在后台继续运行预设时间之后的显示界面。如图6所示，(a)表示第一应用为游戏应用时的第一界面，(b)表示手机由展开状态转变为折叠状态时，手机显示第二应用(为“微信”)的显示界面，(c)表示手机由折叠状态转变为展开状态时，手机显示第一界面。其中，第一界面为游戏匹配玩家的界面，图示中包括倒计时601，时间为30秒，第二界面在前台运行20秒之后，手机由折叠状态转变为展开状态，手机显示第一界面，第一界面中的倒计时601为10秒。
可选的，第一界面中还可以包括等待信息。当手机由展开状态转变为折叠状态时，可以根据等待信息在后台运行第一应用。例如，响应于手机由展开状态转变为折叠状态，手机根据等待信息的第一指令，在后台继续运行第一应用。其中，第一指令用于指示第一应用按照前台运行的状态在后台继续运行。
可以理解的是，手机还可以根据第一界面中包括的等待信息识别第一界面是等待场景的界面。例如，第一应用是游戏应用时，第一界面可以为图6中(a)所示的游戏玩家匹配界面，需要等待其他玩家加入游戏之后开始游戏。又例如，第一应用是游戏应用时，第一界面可以是游戏角色死亡时的等待界面，需要等待预设时间之后游戏角色才能复活可以继续游戏。又例如，第一应用是视频应用，第一界面可以是视频播放前的广告播放界面，需要等待广告播放时间结束之后，播放视频。
示例性的，第一界面的等待信息中可以包括等待时间。例如，第一界面为图6中(a)中所示的游戏玩家匹配界面，等待时间601为30秒，该等待时间601是等待其他玩家加入游戏的时间。其中，应用中当前的场景为需要用户等待一段时间的场景均为等待场景，且手机可以识别出应用中的等待场景。
示例性的，手机识别应用当前场景为等待场景的方式可以是，在手机中设置场景识别通道，该场景识别通道可以包括函数，场景识别通道可以识别该应用的当前的场景。例如，第一应用在前台运行，第一应用的软件开发工具包(Software Development Kit，SDK)可以通过应用程序接口(Application Program Interface，API)与场景识别通道建立连接。场景识别通道识别第一应用当前显示的第一界面，并确定该界面为等待场景的界面。或者，第一应用的SDK通过API向手机的控制器发送显示指令，该显示指令用于指示第一应用的第一界面为等待场景。
可以理解的是，手机还可以使用其他的方式识别前台运行的第一应用的显示界面为等待场景，具体方式不做限定。
示例性的，手机可以识别第一界面中的等待信息，若确定第一界面中包括等待信息，则确定第一界面为等待界面。其中，第一界面中的等待信息可以是，倒计时图标、等待时长文字信息、或暂停信息等。例如，手机识别到第一界面中包括“广告时间”、“等待匹配”、“等待复活”或者“倒计时”等字样时，确定该界面为等待界面。
用户使用手机的过程中，手机处于展开状态。若第一界面为等待场景的界面，用户想要在等待场景的等待时间中使用其他的应用，手机响应于由展开状态转变为折叠状态，手机主屏显示第二应用，手机在后台运行第一应用。为了提供更好的用户体验，手机可以在等待场景中的等待时间结束或即将结束时提醒用户，使得用户不至于错过等待时间结束的时刻。
在一些实施例中，第二界面可以包括等待信息。
示例性的，第一界面为等待场景的界面，识别等待场景中的等待信息，将第一界面中的等待信息显示在第二界面。或者，识别等待场景中的等待信息，确定等待信息中的剩余等待时长，将剩余等待时长以倒计时的方式显示在第二界面。如图8中(a)所示，第二界面为“微信”界面，第一界面中的等待信息以倒计时的方式显示在第二界面。
在一些实施例中，第二界面还可以显示第一提示信息。其中，在等待信息的剩余等待时长结束时，手机显示第一提示信息。或者，在等待信息的剩余等待时长结束前的预设时间，手机显示第一提示信息。第一提示信息用于指示等待信息的剩余等待时长结束或即将结束。
示例性的，第一界面为等待场景的界面，识别等待场景中的剩余等待时长。如图8中(b)所示，第一应用在后台继续运行，手机可以实时获取第一界面中的剩余等待时长，确定剩余等待时长结束或即将结束时，在“微信”应用界面中显示第一提示信息。
例如，用户在使用手机的过程中，手机处于展开状态，第一应用为游戏应用(如，王者荣耀)。游戏应用中的界面为游戏角色死亡等待复活的界面，如图9中(a)所示。手机检测到用户的折叠事件，手机由展开状态转变为折叠状态，手机显示第二应用的界面，第二应用为“微信”，如图9中(b)所示，其中，“微信”界面中包括“王者荣耀”的等待时间。在第二应用在前台运行预设时间之后，如30秒，手机检测到用户的展开事件，手机由折叠状态转变为展开状态，手机显示“王者荣耀”的界面，如图9中(c)所示，游戏角色复活，游戏继续。其中，由于第一应用一直在后台继续运行，手机可以获取第一应用中的等待时间，若检测到游戏等待时间小于1秒，手机显示弹窗提示， 如图9中(d)所示。手机显示界面的变化可以是由图9中(a)切换至图9中(b)，由图9中(b)切换至图9中(c)；或者，由图9中(a)切换至图9中(b)，由图9中(b)切换至图9中(d)，由图9中(d)切换至图9中(c)。
在另一些实施例中，手机在后台运行第一应用，在前台运行第二应用显示第二界面的过程中，手机还可以播放第一应用的音频信息。
在一种情况下，手机运行第二应用不需要使用手机的音频资源。手机可以使用音频资源播放后台运行的第一应用的音频信息。例如，第二应用为阅读应用，用户未使用音频资源，第一应用为游戏应用，第一应用可以使用手机的音频资源播放游戏背景音乐。
在另一种情况下，手机运行第二应用需要使用手机的音频资源。如此，手机使用音频资源播放第一应用的音频信息与手机使用音频资源播放第二应用的音频信息存在资源冲突。在这种情况下，手机可以使用音频资源播放前台运行的第二应用的音频信息；或者，手机可以使用音频资源播放以前台运动的状态在后台运行的第一应用的音频信息；或者，手机可以使用音频资源播放第一应用和第二应用中优先级较高的应用的音频信息。
例如，第一应用和第二应用的音频冲突时，手机可以关闭第一应用的音频，播放第二应用的音频。例如，手机在前台运行“微信”，在后台运行“王者荣耀”时，如果用户点击微信好友发送的语音信息或在微信应用中播放视频或音频时，可以认为“微信”和“王者荣耀”的音频冲突，手机关闭“王者荣耀”的音频，播放“微信”的音频。
在另一些实施例中，手机在前台运行第二应用，在后台运行第一应用时，无论第一应用和第二应用的音频是否冲突，手机也可以一直关闭第一应用的音频。
本申请实施例中手机可以响应于状态的变化，显示不同的应用界面。具体包括，在展开状态时显示第一应用的界面，响应于由展开状态转变为折叠状态，手机显示第二应用的界面，第一应用在后台运行，其中，第一应用在后台运行的状态与在前台运行的状态一致。响应于手机由折叠状态转变为展开状态，手机显示第一应用的显示界面。能够提高等待场景下的时间的利用率，提升用户体验。
