Description

应用数据管理方法、设备、产品及介质
本申请要求于2022年09月30日提交中国专利局、申请号为202211215773.2、申请名称为“应用数据管理方法、设备、产品及介质”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
本申请涉及终端领域，尤其涉及一种应用数据管理方法、设备、产品及介质。
背景技术
多个应用程序在获取终端的存储权限后，均可以在终端的存储空间中任意读取和写入文件，导致终端操作系统无法分辨终端存储的文件分别来自于哪个应用程序，也无法区分缓存文件以及用户保存的媒体文件(例如图片、视频以及音频)等文件类别。进而终端无法将存储空间的文件按所属应用程序或者按文件类别进行分类，使得用户在对存储空间进行管理时，例如需要删除用户通过某一应用程序保存的图片时，需要注意逐一辨别存储空间中文件是否属于该应用程序，以及分辨文件的类别是否为图片，增大了操作难度。
在一些方案中，第三方清理类应用的运营人员可以定期分析存储空间中文件所属的应用程序以及类型，根据分析结果生成分析规则，使得第三方清理类应用对终端存储空间进行扫描后，得到的每个文件的文件类别以及所属应用程序。
但是，运营人员是基于应用程序创建的各个文件夹去分析各个文件夹中存储的文件的类型，导致对每个应用程序的文件类别的分析结果都不相同。用户要对不同应用程序的文件进行管理时，还需要分别去理解每种分类下文件的用途和/或来源，使得用户在管理文件时效率较低。

为更加清楚理解本申请的方案，下面首先介绍应用程序在终端写入文件的过程。
目前，用户可以根据需求在终端上安装和卸载应用程序。应用程序在安装时，需要向终端获取存储权限，用户在终端授予应用程序存储权限后，应用程序可以随意访问终端存储器的存储空间。进而，应用程序可以在存储空间建立文件夹保存应用程序运行时应用程序产生的缓存(例如浏览的网页的页面信息)以及用户通过应用程序保存的媒体文件(例如图片、视频以及音频)等等。并且，应用程序还可以将上述数据写入终端操作系统建立的文件夹中，例如，应用程序将产生的图片写入系统相册中，用户通 过终端自带的相册软件就能查看到所有应用程序产生的图片。
因此，终端上已安装的多个应用程序均可以在终端的存储空间中任意读取和写入文件，导致用户和终端操作系统无法分辨终端存储的文件分别来自于哪个应用程序，也无法区分哪些文件是系统文件，哪些文件是缓存文件，使得用户无法便捷地对存储空间进行管理。例如，无法便捷得进行文件删除以实现存储空间的释放，当用户无法便捷地删除存储空间中的文件时，进而终端存储空间中文件越来越多，大量残留文件占用存储空间，终端可用存储空间越来越少，终端的系统越来越慢。
为解决上述问题，在一些实施例中，通过第三方清理类应用的运营人员定期分析存储空间中文件的文件类别，从而根据分析结果生成分析规则。并通过第三方清理类应用对终端存储空间进行扫描，将扫描到的文件再根据上述分析规则进行分析，以获得每个文件的文件类别以及文件所属应用程序，例如第三方清理类应用可以根据分析规则分析该文件属于应用程序的源代码还是缓存文件，又或者是媒体文件等，并将分析结果展示给用户。进而，用户就能通过第三方清理类应用扫描和分析的结果对存储空间进行管理。
举例来说，第三方清理类应用可以扫描手机10的存储空间，并分析手机10存储空间中各个文件的用途，将手机10中存储的缓存文件进行显示。如图1所示，图1示例性示出了手机10中第三方清理类应用对扫描得到的缓存文件进行显示的界面101。其中，界面101中显示框1011显示了手机10中存在缓存垃圾共86.3兆字节(Megabytes，MB)，缓存垃圾为手机10操作系统在运行应用程序时产生的临时数据，例如浏览过的网页的数据。缓存垃圾还具体分为了手机缓存垃圾、系统缓存垃圾以及云空间的垃圾。手机缓存垃圾包括手机10中所有应用程序在运行时产生的缓存文件，系统缓存包括手机10操作系统运行过程中产生的缓存文件，云空间的垃圾包括手机10在云服务器中存储文件中的缓存文件。
第三方清理类应用程序还会扫描手机10中应用程序产生的音频、图片以及视频等媒体文件，例如界面101中显示框1012示出了对手机10深度检出后确定的手机10中还存储有97.8MB媒体文件。用户通过点击控件1013即可对上述缓存垃圾和深度检出的文件进行删除。
在另一些实施例中，第三方清理类应用还可以进一步将扫描到媒体文件按文件类别进行分类。例如，根据文件类别可以将手机10中的媒体文件按图片、视频、音频、大文件、应用以及安装包等进行分类。示例性地，如图2所示，手机10中第三方清理类应用显示的界面102中包括显示框1021，用户可以根据显示框1021中文件的分类对文件进行管理。
但是，由于应用程序可以随意将上述媒体文件写入任意文件夹，第三方清理类应用也只是根据文件类别，例如，根据文件的后缀(例如：.jpg、.avi或者.exe)以及根据文件的数据大小对文件进行分类的，第三方清理类应用也无法分析到每个文件具体来源于哪个应用程序。示例性地，当用户点击图2中显示框1021中的图片对应的图标之后，第三方清理类应用将在手机10上显示如图3所示的界面103，如界面103所示第三方清理类应用程序仅能将图片按时间顺序进行排序，而不能将图片按应用程序进行分类。
因此，用户在对某一分类的文件进行清理时，无法获取到该分类中文件分别源于哪个应用程序，当用户需要删除某一应用程序产生的媒体文件时，还需要逐一去分辨哪些文件是该应用程序产生的，会消耗用户大量时间，影响用户使用体验。
为解决上述问题，在另一些实施例中，第三方清理类应用的运营人员还可以定期分析每个应用程序创建的文件夹以及产生的文件，将分析结果记为规则。通过第三方清理类应用对终端存储空间进行扫描，将扫描到的文件夹和里面的文件再根据上述规则进行分析，就能得到的每个文件所属的应用以及其用途。进而，用户就能对某一应用程序产生的数据进行管理。
示例性地，如图4所示，第三方清理类应用基于对“视频应用”产生的文件进行的分析，可以在手机10存储空间中确定视频应用所创建的文件夹，并对该文件夹下各个目录中的文件进行显示，用户可根据需求对该视频应用产生文件进行删除。
但是，运营人员的分析结果是依赖于应用程序自身创建的文件夹的目录的，最终所呈现的结果可能过于专业，普通用户难以理解，如图4中界面104所示，视频应用产生的文件包括“日志文件”、“网页缓存”以及“引导图片缓存”，普通用户难以理解上述各类别文件的区别，进而无法对文件进行管理。
并且，通过上述第三方清理类应用扫描和分析存储空间的文件对存储空间进行管理，需要第三方清理类应用的运营人员定期去分析应用程序和操作系统产生文件，每当应用程序或操作系统更新，运营人员又需要重新去分析产生的文件的用途，这样会消耗大量人力。并且运营人员的分析结果不一定完全正 确，当运营人员的分析有误时，用户可能会将有用的文件清除掉，甚至误删应用程序的程序文件，导致应用程序或操作系统没法正常运行，影响用户体验。
为解决上述问题，在另一些实施例中，终端还可以限制应用程序产生的文件的存储区域，终端为每个应用程序分配了独立的存储空间，每个应用程序的文件都能存储在对应的文件夹下，其他应用程序无法访问该应用程序的数据。这样，终端能根据文件所属的文件夹确定文件所属的应用程序。
但由于应用所有的数据都只能存储在这个文件夹，而文件夹内部应用存储的内容没有细分。又因为其他应用程序无法访问该应用程序的文件，第三方应用程序无法对应用程序的文件进行分类用户想要对应用对应的数据进行管理，例如删除部分文件，只能选择删除整个文件夹，如此，导致用户仍然无法对存储空间进行便捷的管理。
综上，上述方案仍然均难以实现存储空间的便捷管理。当用户无法便捷地管理存储空间，例如便捷的删除存储空间中的文件时，会导致终端存储空间难以及时释放，影响终端的系统运行。
为了解决上述问题，本申请提供了一种应用数据管理方法，应用于终端100。该方法在终端100中设置了文件读写框架，文件读写框架中设置有多个文件写入接口，每个文件写入接口对应不同的文件类别。应用程序在向终端100写入不同类别的文件时，需要通过该文件类别对应的接口进行写入，并且，终端100会获取写入文件的应用程序的唯一标识，进而可以确定文件所属的应用程序。如此，在某个应用程序通过调用写入文件的类别所对应的接口类型写入文件时，将写入文件的应用程序的唯一标识和写入文件的文件类别保存在信息记录表中。即信息记录表中存储有各个文件所属的应用程序的唯一标识、文件类别。
如此，终端100不需要借助第三方清理类应用对应用程序产生的文件进行分析，根据信息记录表中各个文件所属的应用程序以及文件类别，用户就能按应用程序和文件类别对查找文件，并按需对文件进行删除或保留等操作。该方法无需耗费额外的人力去分析文件，不会产生文件类别分析出错，导致用户误删文件的情况。
其中，文件类别包括隐私文件、公共文件。由于不同文件的隐私权限不同的，因此根据文件的隐私权限，将应用程序可以分享给其他应用程序的文件称为公共文件，应用程序不分享给其他应用程序的文件称为隐私文件。进一步地，还具体将公共文件按类型分为了视频、音频、相机拍摄的图片、短距接收或下载的文件、其他图片以及文档等子文件类别，其中其他图片为非相机拍摄的图片和非短距接收或下载的图片。应理解，公共文件和隐私文件还可以包括其他子文件类别，本申请对公共文件和隐私文件的子文件类别划分也不作具体限定。
在一些实施例中，文件读写框架也可称为用户数据访问框架。公共文件也可称为媒体文件。隐私文件也包括图片、视频和文档等文件，例如应用程序的用户密码、聊天记录以及数据库记录等。但上述隐私文件是应用程序不分享给其他应用程序的文件。例如，应用接收到图片，但用户并没有将该图片保存到终端100中，此时该图片为隐私文件，而当用户将该图片保存到终端100后，该图片就属于公共文件。另外，应用程序产生的缓存文件也可以根据需求划分为公共文件或者隐私文件。
文件读写框架可以是软件模块，一般位于终端100的应用程序框架层。文件读写框架可以包括隐私文件读写框架和公共文件读写框架。隐私文件读写框架向应用程序提供了隐私文件写入/读取接口，用于应用程序写入或读取隐私文件。公共文件读写框架向应用程序提供了公共文件写入/读取接口，用于应用程序写入或读取公共文件。公共文件写入接口还可以包括相机(camera)拍摄的图片写入/读取接口，其他图片(image)写入/读取接口，视频(video)写入/读取接口，音频(audio)写入/读取接口以及文档(documents)写入/读取接口，短距接收或下载的文件写入/读取子接口等接口。应理解，在还具有其他文件类别的情况下，文件读写框架还可以包括其他与文件类别对应的写入/读取接口，本申请对文件接口类别的划分也不作具体限定。
在一些实施例中，公共文件读写框架向应用程序提供了公共文件写入/读取接口，公共文件写入/读取接口还可以包括不同类别参数，不同文件类别对应不同公共文件写入/读取接口的类别参数，类别参数可以用于指示文件类别为视频、音频、相机拍摄的图片、短距接收或下载的文件、其他图片以及文档。
如图5所示，终端100的应用程序框架层可以包括隐私文件读写框架和公共文件读写框架，应用1能通过隐私文件读写框架提供的隐私文件写入接口向终端100写入隐私文件，以及能通过公共文件读写框架提供的公共文件写入接口向终端100写入公共文件。
此外，如前所述，在一些实施例中，存在用户想要对应用的文件进行管理的情况，为此，本申请另外一些实施例，公开了一种应用数据管理方法，该方法用户在对文件进行管理时，可以通过信息记录表获取终端100文件所属的应用，然后显示终端100上所有应用的应用列表，用户可以根据需求选中目标应用，然后终端100会根据信息记录表中目标应用文件的文件类别显示文件类别列表，用户可以选用目标文件类别，然后对该目标应用中目标文件类别下的文件进行管理，具体可以执行删除、移动、复制、分享等操作。
如图6中(A)示例性示出了终端100上应用数据管理的界面106A，界面106A显示了终端100上“视频应用”、“音乐”和“浏览器”三个应用程序在存储空间中占用的大小。当用户点击显示框1061时，终端100将如图6中(B)所示按文件类别显示“视频应用”的文件，其中，由于隐私文件为不能被其他应用所访问的文件，因此应用数据管理中只显示“视频应用”的隐私文件占用的存储空间大小，而不能显示“视频应用”隐私文件中的具体文件。相反，公共文件是可以被其他应用所访问的，应用数据管理中按“存储的图片”、“存储的视频”、“存储的音频”以及“存储的文档”四个分类对“视频应用”的公共文件进行显示，用户可以通过点击显示框1063中的区域对对应的文件类别进行选择。
在另一些实施例中，基于用户对文件进行管理，还可以通过信息记录表获取终端100文件总共具有的文件类别，然后显示终端100上所有文件类别，用户可以根据需求选中目标文件类别，然后终端100会根据信息记录表中具有目标文件类别的文件的应用，显示应用列表，用户可以选用目标应用，然后对该目标文件类别下目标应用的文件进行管理。具体可参考后文图12及其相关描述。
这样，终端100能将存储空间中的文件按应用程序进行分类，并对于每个应用程序的文件还能按文件类别进行分类，或者，先将文件按文件类别进行分类，并对于每个文件类别还能按应用程序进行分类，使得用户能根据终端100对文件的分类结果对应用程序某一分类的部分文件进行便捷管理，而不是删除应用程序对应的整个文件夹。
综上所述，通过本申请提供的应用数据管理方法，终端100不需要借助第三方清理类应用对应用程序产生的文件进行分析，就能确定存储空间中的文件所属的应用程序以及文件的类别。该方法无需耗费额外的人力去分析文件，并且终端100是直接通过应用程序写入文件时的接口确定的文件类别，不会产生文件类别分析出错，导致用户误删文件的情况。因此，终端100能将存储空间中的文件按应用程序和文件类别进行分类，使得用户能根据终端100对文件的分类结果对文件进行管理，既节省了人力资源，又提高了用户体验感。

下面结合图8对手机10安装第一应用程序的过程进行详细描述。
S801：第一应用向应用管理框架发送安装第一应用的请求。
用户可以通过手机10的应用商城下载应用程序，或者通过手机10中的浏览器下载应用程序。当用户在应用商城或浏览器发送安装第一应用的请求时，第一应用将通过应用商城或浏览器向手机10的应用管理框架发送安装应用程序的请求。
示例性地，参见图9中的(A)，界面901为手机10的主界面，手机10可以检测到作用于界面901中应用商城图标9011的触控操作(如在图标9011上的点击操作)，并响应于该操作启动应用商城程序。参见图9中的(B)，界面902为应用商城的界面，用户可以在该应用商城中下载需要的各种应用，例如，用户可以点击视频应用对应的控件9012，手机10检测到作用于控件9012的触控操作，即手机10的应用管理框架获取到安装视频应用的请求。

在一些实施例中，应用管理框架检测到第一应用通过隐私文件读写框架写入了安装文件后，应用管理框架还将对APK文件等安装文件进行解析，以获取第一应用的组件、配置文件等信息，进而第一应用可以在手机10上运行。
下面结合图10对第一应用向手机10写入数据的过程进行详细描述。
S1001：第一应用产生第一文件。
第一应用在运行中会产生数据，第一应用产生的数据包括第一应用在运行过程中产生的隐私文件，用户通过第一应用保存的图片、视频、音频等文件，第一应用要进行更新时会获取到的APK文件，以及第一应用运行过程中所需的驱动程序等。
S1002：第一应用确定第一文件的文件类别。
第一应用将根据手机10提供的文件读写接口，判断第一文件的文件类别，以使第一应用能调用对应的接口写入数据。
举例来说，第一应用产生的文件可以按文件是否可共享给其他应用而分为隐私文件和公共文件，其中，公共文件为应用程序可以分享给其他应用程序的文件，例如图片、视频以及音频。隐私文件为不分享其他应用程序的文件，例如应用程序中的用户密码，聊天记录，数据库记录等。
在一些实施例中，如果第一文件属于公共文件，第一应用还会进一步将按文件类别对第一文件进行分类，判断第一文件属于视频、音频、相机拍摄的图片、短距接收或下载的文件、其他图片以及文档中哪一类。
S1003：第一应用通过第一文件写入接口写入第一文件。
第一应用根据第一文件的文件类别确定写入该第一文件所需要调用的接口，进而根据对应的接口写入第一文件。例如，调用第一文件写入接口，第一文件写入接口对应第一文件的文件类别。
在一些实施例中，手机10具有多个文件写入接口，文件写入接口可以包括隐私文件写入接口、公共文件写入接口，公共文件写入接口还包括视频写入子接口、音频写入子接口、相机拍摄的图片写入子接口、短距接收或下载的文件写入子接口、其他图片写入接口以及文档写入子接口。
S1004：手机10向第一应用获取第一应用的唯一标识。
手机10在接收到第一应用写入第一文件时，还会向第一应用获取第一应用的唯一标识，以确定第一文件所属的应用。
S1005：手机10根据第一文件写入接口确定第一文件的文件类别，并存储第一应用的唯一标识和文件类别。
手机10能根据第一应用写入第一文件时调用的文件写入接口或者接口参数确定文件类别。手机10还会将第一文件的文件类别、第一文件的绝对路径、第一应用的唯一标识存储至信息记录表中。
在一些实施例中，手机10可以根据第一应用调用的是有隐私文件写入接口、视频写入子接口、音频写入子接口、相机拍摄的图片写入子接口、其他图片写入接口还是文档写入子接口，确定第一文件是隐私文件，还是公共文件中的视频、音频、相机还是其他图片。
在另一些实施例中，在第一应用调用的是公共文件写入接口的情况下，手机10还可以根据第一应用调用的公共文件写入接口的类别参数确定第一文件的文件类别，其中，公共文件写入接口还包括视频、音频、相机拍摄的图片或视频、短距接收或下载的文件、其他图片文档等不同类别参数。
在另一些实施例中，手机10在接收到第一应用写入第一文件后，还会根据文件写入接口将第一文件写入手机10预制文件夹中对应的目录下，其中预制文件夹中包括各个文件类别。
示例性地，如图11中所示，界面1101示出了手机10为预制文件夹，预制文件夹下还具体包括图片、视频、音频以及文档文件夹，其中图片文件夹用于存放为其他图片写入接口写入的文件，视频文件夹用于存放视频写入子接口写入的文件，音频文件夹用于存放音频写入子接口写入的文件，文档文件夹用于存放文档写入子接口写入的文件。
在一些实施例中，由于隐私文件不分享其他应用程序的文件，在不删除第一应用的情况下，只有第一应用能对隐私文件夹中的数据进行读写，因此手机10不会显示存放隐私文件夹。
在另一些实施例中，手机10还会将第一文件的绝对路径、文件大小、创建时间等数据一起写入信息记录表。
下面结合图12对管理第一应用的数据的过程进行详细描述。
S1201：应用管理框架获取到管理第一应用的文件的请求。
手机10还包括如手机管家等应用，该应用用于通过应用管理框架对手机10中的数据进行管理，用户可以基于手机管家等应用对第一应用的数据进行管理。在手机10获取到用户对文件进行管理的操作时，手机10还将获取信息记录表中，所有文件所属的应用，然后将显示应用列表，用户可以点击应用列表中的目标应用，对目标应用的文件进行管理。
示例性地，参见图13中的(A)，界面1301为手机10的主界面，手机10可以检测到作用于界面1301中手机管家图标1302的触控操作。响应于上述操作，手机10将运行手机管家应用，参见图13中的(B)，界面1303为一种手机管家运行后的界面图，手机管家可以通过应用管理框架按应用程序和公共文件的分类对文件进行管理。
当手机10检测到作用于应用数据管理显示栏1304的触控操作，手机10将显示各个应用程序，以及各个应用程序所占用的存储空间大小，手机10获取到用户选中第一应用的操作，即手机10获取到管理第一应用的数据的请求。具体可参考上述图6中的(A)示出的界面，此处不再赘述。
S1202：应用管理框架将第一应用的文件按文件类别进行显示。
应用管理框架将根据信息记录表中属于第一应用的文件的文件类别，显示文件类别列表，具体可参考上述图6中的(B)示出的界面，此处不再赘述。在一些实施例中，应用管理框架仅用于获取第一应用的文件信息，还需要窗口管理器等框架才能在手机10的显示屏显示第一应用的文件的信息。
在一些实施例中，应用管理框架也可以先显示文件类别列表，然后在用户选中了目标文件类别的情 况下，再显示具有目标文件类别的文件的应用列表。举例来说，用户在如图13中的(B)所示的界面中选中公共文件管理的显示栏1305，响应于用户操作，参见图14中的(A)，应用管理框架将把所有应用程序的数据按拍摄的照片、存储的图片、存储的视频、存储的音频以及存储的文档按界面1401所示进行显示，并显示各个类别的文件共占用的存储大小。
应用管理框架检测到作用于某一类别的文件的触控操作，应用管理框架将显示该类别的文件。应用管理框架在显示该类别的文件时，还能按文件所属的应用程序进行排序显示。参见图14中的(A)手机10检测到作用于“存储的图片”对应的显示栏1402的触控操作，手机10通过应用管理框架获取到文件数据显示如图14中的(B)所示的界面1403，界面1403将手机10中通过图片接口写入的数据进行了显示。
应用管理框架按不同排序方式对文件进行显示，例如按时间排序、按应用排序或者按大小排序。参考图14中的(B)，界面1403包括控件1404，控件1404用于更改文件排序方式，应用管理框架检测到作用于控件1404的触控操作，参考图15中的(A)，界面1501显示多种排序方式，包括按时间排序、按应用排序以及按大小排序。手机10检测到作用于按应用排序对应控件1502的触控操作，参考图15中的(B)，界面1503示例性展示了将存储的图片按应用程序进行排序的结果，其中，包括视频应用和浏览器存储的图片。
S1203：应用管理框架获取到用户对目标文件进行第一操作的请求。
应用管理框架获取到作用于第一应用中目标文件的触控操作，表示用户需要对目标数据进行相应操作，可进行的操作包括移动、删除、复制、分享、打印以及重命名等。
在一些实施例中，用户在对目标数据进行第一操作之前，还可以查看目标文件的详细信息，例如文件名称、文件大小、创建时间等等。具体参考图16(A)，用户通过点击界面1601中的图片1602的图标来选中视频应用存储的图片中的图片1602，参考图16中的(B)，应用管理框架在界面1603中显示提示框1604，提示框1604示出了图片1602的详细信息，其中，包括名称：“目标文件.jpg”，所述应用：第一应用；图片大小：1.5MB，创建时间：2022.09.09。
用户还可以通过点击图片上的控件来实现对图片的操作，参考图17中的(A)，用户通过点击界面1701图片1602图标上的控件1702，将显示如图17中的(B)所示的界面，其中界面1703中的提示框1704示出了用户可对图片1602进行的操作，例如分享、移动、复制和删除，用户可以根据需求选择需要对图片1602进行的操作。
S1204：应用管理框架将目标文件按第一操作进行处理。
应用管理框架根据获取到的用户对目标数据进行第一操作的请求，对目标数据进行处理。
示例性地，参考图18中的(A)，应用管理框架检测到作用于提示框1704中删除图标1801的触控操作，手机10将删除图片1602。对应地，参考图18中的(B)，界面1802中不再显示图片1602。
下面结合图19对手机10卸载第一应用的过程进行详细介绍。
S1901：应用管理框架获取到卸载第一应用的请求。
用户可以通过手机管家来删除应用程序，也可以直接对应用程序进行删除操作。当应用管理框架获取到上述用户操作时，即认为应用管理框架获取到卸载第一应用的请求。
参考如图6中的(B)，用户可以通过手机管家删除视频应用，应用管理框架检测到作用于控件1064的触控操作，即可认为手机10获取到卸载视频应用的请求。
或者参考如图20中的(A)，应用管理框架检测到作用于视频应用图标2001的长按操作，手机10将显示提示框2002，在手机10再检测到基于卸载控件2003的触控操作，即可认为手机10获取到卸载视频应用的请求。
S1902：应用管理框架获取第一应用的文件，并删除第一应用的隐私文件。
应用管理框架将根据信息记录表确定手机10中属于第一应用的数据，然后根据信息记录表中文件类别，确定第一应用的隐私文件。手机10在卸载第一应用时，将删除第一应用的隐私文件。
在一些实施例中，信息记录表中也可以不记录隐私文件，手机10将隐私文件存储在内部存储器中，应用管理框架将根据第一应用的唯一标识直接在内部存储器中读取第一应用的隐私文件。
S1903：应用管理框架判断是否存在公共文件。
应用管理框架在卸载第一应用时，还会根据信息记录表中文件类别判断是否存在公共文件，所述公 共文件可被其余应用程序读写。若判断结果为是，则执行步骤S1904，若判断结果为否，则完成对第一应用的卸载。
S1904：手机10提示第一应用公共文件的大小。
应用管理框架将根据信息记录表中第一应用的文件的文件类别，检测到手机10中还有第一应用的公共文件未删除时，应用管理框架将提示手机10中还存储有第一应用的公共文件的信息。
参考如图20中的(B)，手机管家基于应用管理框架检测到删除视频应用的请求之后，将显示提示框2004，提示用户手机10中还存储有第一应用中的公共文件的信息。
在一些实施例中，手机10还会根据信息记录表中第一应用文件的文件类别，确定文件属于公共文件下的具体文件类别，例如，视频、音频、相机拍摄的图片、短距接收或下载的文件、其他图片以及文档等。然后，向用户提示上述各个文件类别下文件的大小。
S1905：应用管理框架获取用户对第一应用的公共文件的第二操作，基于第二操作对第一应用的公共文件进行处理。
用户可以基于手机10的提示，选择对第一应用的公共文件进行删除或者保留，应用管理框架将基于用户操作对第一应用的媒体数据进行删除或者保留。
在一些实施例中，应用管理框架卸载第一应用时还可以先对公共文件进行处理，再删除隐私文件。
