图3示出了本申请实施例提供的一种后台应用恢复方法的示意性流程图，作为示例而非限定，该方法可以应用于上述电子设备100中。
参考图3，后台应用恢复方法包括：
S310、响应来自用户的删除操作，删除至少一个后台应用并将删除的后台应用存入第一存储空间。
一些实施方式中，用户的删除操作可以是一个独立的操作，也可以是多个操作的组合。
当删除操作为独立的操作时，可以是电子设备接收到的语音控制指令、手势操作或者对物理按键的操作等。例如，当电子设备的麦克风接收到语音指令“清理后台应用”时，电子设备可以将所有的后台应用删除。或者，当电子设备的触控面板接收到用于指示清理后台应用的手势操作时，也可以将所有的后台应用删除。再或者，若设置了用于清理后台应用的物理按键，当该物理按键接收到用户的按压操作发出信号时，则可以将所有的后台应用删除。
当删除操作为多个操作的组合时，可以是对电子设备显示界面的多个控制操作的组合。例如，当电子设备接收到从底部屏幕边缘向上滑动的滑动操作后，电子设备的显示界面可以显示后台应用列表中的多个正在运行的后台应用。该界面中可以包括多个后台应用的预览界面，每个后台应用的预览界面上设置有用于指示删除该后台应用的删除标记。该界面中还可以包括用于指示删除所有后台应用的清理标记等。其中，后台应用列表中包括至少一个正在运行的后台应用。
然后，电子设备接收到用于指示删除一个或多个后台应用的滑动操作后，将对应的后台应用删除。其中，用于指示删除一个或多个后台应用的滑动操作包括：点击后台应用界面中后台应用对应的删除标记。或者，点击后台应用界面中的清理标记。再或者，还可以通过点击后台应用的预览界面，并向预设的方向拖动该预览界面一段距离，以指示删除该后台应用。
一些实施方式中，删除至少一个后台应用并将删除的后台应用存入第一存储空间，可以将删除的后台应用从后台应用列表中移除。然后，将删除的后台应用、删除的后台应用的恢复信息以及用户的第一识别标签进行绑定，保存在第一存储空间中。
图4示出了本申请实施例提供的一种后台应用恢复方法的系统结构示意图。
作为示例，参考图4，其中包括后台应用显示模块、虚拟删除模块以及删除路径列表存储模块。后台应用显示模块可以是在随机存取存储器(Random Access Memory，RAM)中运行的服务，用于在检测到指示显示正在运行的后台应用的操作时，从RAM中获取正在运行的后台应用，并在电子设备的界面进行展示。
虚拟删除模块，可以是系统服务层和框架层中的服务模块，用于识别当前删除后台应用的用户的第一识别标签。并将删除的后台应用、删除的后台应用的恢复信息以及用户的第一识别标签进行绑定，并交给删除路径列表存储模块。删除路径列表存储模块则用于将绑定好的删除的后台应用、删除的后台应用的恢复信息以及用户的第一识别标签存储在只读存储器(Read-Only Memory，ROM)中的第一存储空间内。删除的后台应用包括后台应用的运行数据。例如，可以包括后台应用的进程数据、调用的服务类型、缓存数据的存储位置等。删除的后台应用的恢复信息则可以包括删除后台应用时的时间、删除后台应用时应用的界面信息等。用户的第一识别标签可以是编号、文字信息或者具有唯一性的字符串等。用户的第一识别标签用于指示用户的身份，例如，用户的身份包括机主、多个家庭成员或访客等。用户的第一识别标签可以根据用 户的声纹特征、面容特征、指纹特征等生物特征进行确定，或者也可以是密码、绘制的图形等可以用于识别用户的信息。
作为示例，可以在电子设备中预先录入多个不同身份用户(如机主和多个家庭成员)的生物特征，当通过对应的生物特征解锁电子设备时，则可以确认当前用户为该生物特征对应用户的身份，即可确定用户的第一识别标签。
需要说明的是，电子设备的每个用户均可删除后台应用，为了区分不同用户的删除的后台应用，删除路径列表存储模块可以将不同识别标签的用户删除的后台应用存储在不同的存储空间中。例如，当删除路径列表存储模块接收到的第一识别标签、删除的后台应用、删除的后台应用的恢复信息时，确定该第一识别标签对应机主，后台应用是机主删除的。则可以将第一识别标签、删除的后台应用、删除的后台应用的恢复信息存储在第一存储空间中机主对应的存储空间内。
而当删除路径列表存储模块接收到的第一识别标签、删除的后台应用、删除的后台应用的恢复信息时，确定该第一识别标签对应家庭成员A，后台应用是家庭成员A删除的。则可以将第一识别标签、删除的后台应用、删除的后台应用的恢复信息存储在第一存储空间中家庭成员A对应的存储空间内。
一些实施方式中，参考图4，在本实施例中，还包括延迟删除模块，延迟删除模块与虚拟删除模块类似，可以是系统服务层和框架层中的服务模块，用于对存储在第一存储空间中的删除的后台应用进行计时。每个删除的后台应用对应一个预设的时长。该预设的时长为后台应用的清理时长。当删除的后台应用在第一存储空间中的存储时长达到删除的后台应用对应的清理时长之后，延迟删除模块将清理删除的后台应用。即延迟删除模块将删除的后台应用以及对应的恢复信息从第一存储空间中删除。
S320、响应来自用户的恢复操作，获取用户的第一识别标签。
一些实施方式中，用户的恢复操作可以是一个独立的操作，也可以是多个操作的组合。
当恢复操作为独立的操作时，可以是电子设备接收到的语音控制指令、手势操作或者对物理按键的操作等。例如，参考图4，当电子设备的麦克风接收到语音指令“恢复后台应用”时，可以通过用户认证模块，根据接收到的语音指令的声纹特征获取对应用户的第一识别标签。其中，用户认证模块可以是系统服务层和框架层中的服务模块，用于对发起恢复操作的用户进行识别。
或者，当电子设备的触控面板接收到用于指示恢复后台应用的手势操作时，也可以通过用户认证模块采集用户的指纹特征或面容特征，以识别用户的第一识别标签。
当恢复操作为多个操作的组合时，可以是对电子设备显示界面的多个控制操作的组合。例如，当电子设备接收到从底部屏幕边缘向上滑动的滑动操作后，电子设备的显示界面可以显示多个正在运行的后台应用。该界面中出了S310的示例中提及的内容，还可以包括用于指示恢复后台应用的恢复按钮。
然后，电子设备接收到点击用于指示恢复后台应用的恢复按钮的操作时，可以通过用户认证模块采集用户的声纹特征、指纹特征或面容特征，以对发起恢复操作的用户进行识别，获得用户的第一识别标签。
图5示出了本申请实施例提供的一种后台应用恢复方法的应用界面示意图。
参考图5，其中示出了多个正在运行的后台应用501以及恢复按钮502。当展示恢复按钮502的区域接收到点击操作时，则电子设备可以确定接收到恢复操作。电子设备可以通过指纹传感器、摄像头或者麦克风采集发起恢复操作的用户的生物特征，并根据用户的生物特征获取该用户的第一识别标签。
S330、根据用户的第一识别标签，从第一存储空间中获取用户删除的后台应用。
一些实施方式中，第一存储空间中可能存储有多个用户删除的后台应用，每个删除的后台应用均对应一个第一识别标签。这个情况下，可以只获取具有该用户的第一识别标签的删除的后台应用。例如，若第一存储空间中存储有机主删除的后台应用(具有机主的第一识别标签)以及家庭成员A删除的后台应用(具有家庭成员A的第一识别标签)。当用户的第一识别标签指示该用户为机主时，则根据机主对应的第一识别标签，获取所有机主删除的后台应用。
S340、响应来自用户的操作，从用户删除的后台应用中确定并恢复至少一个后台应用。
图6示出了本申请实施例提供的另一种后台应用恢复方法的应用界面示意图，图7示出了本申请实施例提供的另一种后台应用恢复方法的应用界面示意图。
一些实施方式中，在从第一存储空间中获取用户删除的后台应用之后，可以在界面中显示用户删除的后台应用的应用名称和图标。参考图6，其中，机主为用户1。在图6中，按照删除的时间顺序显示了机主删除的4个后台应用的名称“应用名称5”、“应用名称6”、“应用名称7”和“应用名称8”。同时，展示了4个恢复选项“选择恢复”、“逐条恢复”、“全部恢复”和“取消恢复”。
这个情况下，用户的操作可以是选择操作。作为示例，选择操作可以是作用于展示“选择恢复”、“逐条恢复”或“全部恢复”区域的点击操作。
例如，当用户的选择操作为作用于展示“选择恢复”区域的点击操作时，参照图7，可以通过高亮“选择恢复”区域提示用户进入了选择恢复的界面。同时，可以通过接收用户作用于“应用名称5”、“应用名称6”、“应用名称7”和“应用名称8”展示区域的点击操作，将选择的应用名称高亮显示，以确定用户需要恢复的后台应用。图7中以选择“应用名称5”和“应用名称7”为例，当确定用户选择了需要恢复的后台应用是，可以展示“确认恢复”按钮，以提示用户再次确认是否进行后台应用恢复。当展示“确认恢复”的区域接收到点击操作后，则确认用户需要恢复“应用名称5”和“应用名称7”对应的后台应用。
然后，参考图4，恢复模块从第一存储空间中，获取“应用名称5”和“应用名称7”的对应的后台应用的恢复信息，并根据“应用名称5”和“应用名称7”的恢复信息，将“应用名称5”和“应用名称7”对应的应用程序添加后台应用列表中，然后从第一存储空间中移除“应用名称5”和“应用名称7”对应的数据。
一些实施方式中，继续参考图6，当用户的选择操作为作用于展示“逐条恢复”区域的点击操作时，每当点击一下，可恢复一个删除时间与当前时间最接近的删除的后台应用。例如，若当前时间为18：00分，应用程序5为17:00分删除，应用程序6为17:12分删除，应用程序7为17:31分删除，应用程序8为17:58分删除。则当展示“逐条恢复”区域的接收到点击操作时，将应用程序8对应的后台应用恢复；当展示“逐条恢复”区域的再次接收到点击操作时，将应用程序7对应的后台应用恢复，其恢复的方 式与上述示例类似，在此不做赘述。以此类推，直至所有删除的后台应用全部恢复，或者接收到终止恢复的操作(例如展示“取消恢复”区域的接收到点击操作)为止。
还有一些实施方式中，继续参考图6，当用户的选择操作为作用于展示“全部恢复”区域的点击操作时，则将“应用名称5”、“应用名称6”、“应用名称7”和“应用名称8”对应的后台应用全部恢复，其恢复的方式与上述示例类似，在此不做赘述。
图8示出了本申请实施例提供的另一种后台应用恢复方法的应用界面示意图。
参考图8，其中，家庭成员A为用户2。在图8中，按照删除的时间顺序显示了家庭成员A删除的2个后台应用的名称“应用名称9”、“应用名称10”。以及4个恢复选项“选择恢复”、“逐条恢复”、“全部恢复”和“取消恢复”。用户2恢复后台应用的方式与用户1类似，在此亦不做赘述。
在本申请中，通过在用户发起恢复操作时获取该用户的第一识别标识，并根据用户的第一识别标识获取该用户删除的后台应用。可以防止其他用户恢复非本人删除的后台应用，防止其他用户通过恢复删除的后台应用获取隐私数据，可以更好的保护每个用户的隐私。
图9示出了本申请实施例提供的另一种后台应用恢复方法的系统结构示意图。
一些实施方式中，参考图9，本申请还提供了用户习惯学习模块，用户习惯学习模块也是系统服务层和框架层中的服务模块，用于根据用户的恢复习惯修改延迟删除模块中的每个后台应用预设的时长(即清理时长)，以学习用户恢复后台应用的习惯，提供更加个性化的服务。
图10示出了本申请实施例提供的另一种后台应用恢复方法的示意性流程图。
参考图10，学习用户恢复后台应用的习惯，包括：
S350、获取每个后台应用的恢复数据，恢复数据包括后台应用的恢复次数和恢复时间间隔。
其中，不同的用户删除相同的后台应用时，该后台应用的清理时长可能不相同。后台应用的恢复次数需要根据不同用户进行统计，例如，在一周内，用户1(机主)恢复了应用程序1的次数为20次(恢复次数)，且通常在删除应用程序1后的10分钟内(恢复时间间隔)进行恢复。用户2恢复了应用程序1的次数为5次，且通常在删除应用程序1后的30分钟内进行恢复。
S360、根据每个后台应用的恢复数据调整每个后台应用的清理时长。
一些实施方式中，每个后台应用对于不同用户的重要性均不相同，因此获取每个后台应用的恢复数据时，需要根据用户的第一识别标识进行区分。
例如，对于上述示例的用户1，在一周内恢复应用程序1的次数最多，且恢复的时间间隔最短，则可以根据应用程序1的恢复数据确认应用程序1对于用户1的重要性提升，即可以延长用户1删除应用程序1后的清理时长。例如，用户1删除应用程序1后的清理时长为15分钟，根据应用程序1对于用户1的重要性变化，可以将清理时长调整为30分钟。
对于上述示例的用户2，在一周内恢复应用程序1的次数最少多，且恢复的时间间隔最长，则可以根据应用程序1的恢复数据确认应用程序1对于用户2的重要性降低，即可以缩短用户2删除应用程序1后的清理时长。例如，用户2删除应用程序1 后的清理时长为15分钟，根据应用程序1对于用户2的重要性变化，可以将清理时长调整为10分钟。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后。各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
