1)应用程序：简称应用，为能够实现某项或多项特定功能的软件程序。通常，电子设备中可以安装多个应用。比如，相机应用、短信应用、邮箱应用、视频应用、音乐应用等。下文中提到的应用，可以是电子设备出厂时已安装的应用，也可以是用户在使用电子设备的过程中从网络下载或其他电子设备获取的应用。
2)透明压缩：在透明压缩中，当应用将原始数据写入文件系统(File system)时，由文件系统本身对数据进行压缩操作，然后将压缩后的数据写入存储设备，比如通用闪存存储(universal flash storage，UFS)；当应用读取数据时，先从UFS中读取压缩后的数据，经由文件系统解压缩后返还给应用。采用透明压缩，可以做到压缩、解压缩对应用完全透明。应当理解，应用对于数据的压缩和解压缩是无感知的。例如，应用所包括的数据的存储格式或者后缀名称在透明压缩、透明解压缩前后不发生变化，应用所包括的数据在透明压缩后变成了压缩数据，应用仍能直接识别、读取该压缩数据。
随着电子设备的发展以及用户需求的提升，用户在终端设备，比如手机上安装的应用越来越多，这些应用的安装数据会占据一部分存储空间。并且，应用在使用过程中会产生大量的数据，这些数据也会占据很大的存储空间。随着使用时间的增加，手机的存储空间会越来越小。
有鉴于此，本申请提供一种应用压缩方法，该方法中可选择应用进行压缩，以节省应用所占的存储空间，提升存储空间利用率，并且能够提升用户体验。
此外，下述实施例涉及的至少一个，包括一个或者多个；其中，多个是指大于或者等于两个。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的。
需要说明的是，本申请实施例提供的应用压缩方法，可以适用于具有显示屏的多种电子设备，诸如手机、平板电脑、可穿戴设备(例如，手表、手环、智能头盔，智能眼镜等)、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等，本申请实施例不作限定。本申请实施例涉及到的电子设备可以是可折叠式电子设备，比如可折叠式手机，可折叠式平板电脑等，本申请对此不作限定。并且，电子设备的示例性实施例包括但不限于搭载 或者其它操作系统的电子设备。

本申请一些实施例中，用户可以在桌面选择要压缩的应用(比如，图库应用)以及压缩方式，并点击压缩按钮，然后空间压缩管理器可扫描应用文件，在应用文件中选择要压缩的文件和文件压缩算法。接着，空间压缩管理器可调用文件系统对图库应用进行压缩。另一些实施例中，可通过系统应用，比如设置应用调用文件系统对图库应用进行压缩。
以下实施例以应用在图1所示的手机100所示的架构中为例进行描述。
在本申请实施例中，应用压缩的过程可以由用户触发，也可以由电子设备来触发，本申请对此不作限定。下面以手机100为例，介绍由用户触发的应用压缩方法。
如图3所示，为本申请实施例提供的一种应用压缩方法流程图，参阅图3所示，该方法可包括如下步骤：
S301：接收用户选择待压缩的应用以及对应的压缩方式的指令。
在一些示例中，用户可通过如下几种方式选择要压缩的应用及其对应的压缩方式：
方式1：用户在主界面上通过手势操作触发应用进入编辑模式，然后选择要压缩的应用及其对应的压缩方式。
示例1：如图4A所示，假设手机100显示图4A中的(a)所示的主界面400，当手机100检测到用户在主界面上的手势操作，比如图中所示的双指捏合的手势操作时，可响应用户的手势操作，显示界面410，例如图4A中的(b)所示。其中，界面410包括带有选择框的多个应用的标识(例如，地图、图库等)，以及压缩方式标识(例如，轻度压缩、中度压缩、重度压缩)。接着，手机100可以检测用户针对应用的选择框的操作，比如用户在图4A中的(b)所示的界面410中选择对应图库应用的应用图标和电子邮件应用的应用图标，图库应用和电子邮件应用的选择框中可显示选中标记(例如，对号√)，然后点击中度压缩方式按钮，手机100可响应该操作，对图库应用和电子邮件应用进行中度压缩，压缩之后的界面可参阅图4A中的(c)所示界面420。其中，界面420中可显示已压缩的应用图标和未压缩的应用图标。对于同一个应用，压缩前的应用图标和压缩后的应用图标可以不同。比如，针对同一应用，压缩前后的应用图标的透明度可以不同；通过改变应用的透明度，可以便于用户区分应用是否被压缩。
应理解，不同的应用可以选择相同或不同的压缩方式。示例性的，比如用户可以先选择图库应用的应用图标，然后点击中度压缩方式按钮，先对图库应用进行压缩。接着，用户可以再选择电子邮件应用的应用图标，然后点击轻度压缩方式按钮，再对电子邮件应用进行压缩。
在一些示例中，如果选择多个应用进行压缩，则对于不同应用，压缩后的应用图标可以相同，也可以不同。比如，选择对图库应用和电子邮件应用进行压缩，压缩后的图库应用的应用图标可以如图4A中的(c)所示，压缩后的电子邮件应用的应用图标上可显示“已压缩”字样等，本申请对此不作限定。
在一些示例中，当同一应用/不同应用选择不同的压缩方式时，压缩后的应用图标的显 示样式可以不同，比如不同的压缩方式对应的透明度可以不同，通过应用的透明度，可以便于用户区分应用的压缩方式。
如图4B所示，在另一些实施例中，当手机100检测到用户在主界面上的手势操作，比如图中所示的双指捏合的手势操作时，可响应用户的手势操作，显示界面430。界面430中可包括带有选择框的多个应用的标识(例如，地图、图库等)，以及压缩按钮431。示例性的，界面上可以不显示上述图4A中的(b)所示示意图中的三种压缩方式。然后，用户可在界面430中选择图库应用和电子邮件应用，并点击压缩按钮431，手机100可响应该操作，对图库应用和电子邮件应用进行压缩，压缩之后的界面可参阅图4A中的(c)所示界面420。
作为一种可能的实现方式，手机100可以根据应用使用的情况，比如应用使用的次数自动为应用选择相应的压缩算法。示例性的，手机100可以根据应用未被使用的天数对应用进行分级，然后不同级别选择不同的压缩算法。比如未使用天数超过7天的应用使用lz4算法，未使用天数超过14天的应用使用Zstd算法，未使用天数超过30天的应用使用zip算法。当然，还可以根据其它的方式自动为应用选择相应的压缩算法，比如根据应用的文件的使用频率来选择压缩算法等，本申请对此不作限定。
需要说明的是，图4A、图4B中所示的手势操作仅是一种示例，在本申请实施例中，手势操作还可以为其它操作，比如，在显示屏上画圈、画多边形等的操作；或者，手势操作还可以是“摇一摇”等操作，本申请实施例不作限定。
应理解，用户选择的要压缩的应用可以包括一个或者多个。例如，用户可以在界面410中勾选多个应用图标，然后对多个应用进行压缩。
下面分别对本申请实施例中涉及到的三种压缩方式进行详细介绍。
1、轻度压缩方式
在这种压缩方式中，可将一个应用的文件分为多个，然后在每一个文件中将文件划分为文件块，最后按照文件块进行压缩，示例性的，如图5A所示，假设应用1包括多个文件，比如可将文件1分为16KB的多个文件块，然后将应用数据写入文件系统，由文件系统对文件块进行压缩，比如可得到12KB的压缩(compress)数据、11KB的压缩数据等。最后，再将压缩后的数据写入UFS器件。与压缩之前的文件相比，文件大小明显缩小。
相应地，在解压缩时可从UFS器件中读取数据，然后在文件系统中解压缩，最后将解压缩的数据提供给应用。
应理解，图中所示的文件大小仅是一种示例，空间压缩管理器可根据应用文件的实际情况划分文件块的大小，例如图中所示的原始数据也可以32KB等，本申请对此不作限定。
在一些示例中，应用的文件可包括文件名、索引节点(inode)、数据部分。其中，inode中可包括文件的字节数、文件的创建日期、文件拥有者的用户标识(User ID)等。示例性的，可采用如下两种方式对应用进行透明压缩：
第一种方式：仅对数据部分进行压缩。示例性的，假设应用的文件为文件1.txt，文件1.txt中的数据内容为1、2、3、4、5、6、7、8、9，则可对1、2、3、4、5、6、7、8、9进行压缩，比如压缩之后的内容为：1-9，即压缩后的文件为文件1.txt，此时文件1.txt中的数据内容为1-9。
第二种方式：对应用文件进行替换。示例性的，假设应用的文件为文件1.txt，文件1.txt中的数据内容为1、2、3、4、5、6、7、8、9，则可对文件1进行压缩，比如数据内容1、 2、3、4、5、6、7、8、9压缩为：1-9，此时可将数据内容为1、2、3、4、5、6、7、8、9的文件1.txt替换为数据内容为1-9的文件1.txt。在这种压缩方式中，可以更改inode中的ID，比如压缩前ID为1，压缩后ID为2。
上述两种方式中，对于应用而言，应用文件的名称、后缀均没有发生变化，仅是存储的数据内容的存储形式发生了变化，因此，应用对于压缩过程无感知。而且，在本申请实施例中对应用压缩时无需删除应用的源文件，即不需要删除应用，这样在后续使用应用时也不需要重新安装，能够节省存储空间，提升用户体验。
2、中度压缩方式
在该压缩方式中，可将应用的全部文件分别压缩为压缩文件。
示例性的，如图5B所示，假设应用1包括N个文件，比如文件1、文件2、文件3…文件N，然后可将文件1压缩为压缩文件1，比如记为：文件1.compress，将文件2压缩为压缩文件2，比如记为：文件2.compress，以此类推，分别对多个文件进行压缩。
3、重度压缩方式
在该压缩方式中，可将应用的全部文件打包为一个文件进行压缩，即压缩为一个压缩文件。示例性的，如图5C所示，假设应用1包括N个文件，比如文件1、文件2、文件3…文件N，然后可将文件1-文件N打包为一个文件进行压缩，比如压缩之后得到的文件为：应用1.compress file。
示例2：如图6所示，假设手机100显示图6中的(a)所示的主界面600，用户可在主界面600上长按应用图标，比如可长按图库应用图标，手机100可响应用户的长按操作，例如显示图6中(b)所示的界面610，该界面610中可包括分享按钮611、卸载按钮612、压缩按钮613。接着，用户可点击压缩按钮613，手机100可响应该点击操作，显示图6中(c)所示的界面620，该界面620中可包括轻度压缩按钮621、中度压缩按钮622、重度压缩按钮623。接着，用户可在界面620中选择压缩方式，比如点击中度压缩按钮622，手机100可响应该操作，对图库应用进行中度压缩，压缩之后的界面可参阅图6中的(d)所示界面630。该界面630中可包括已压缩的应用图标和未压缩的应用图标。其中，已压缩的应用图标的名称下方可显示“已压缩”字样。当然，也可以显示在其它位置，本申请对此不作限定。即可通过文字提示信息提醒用户应用是否被压缩。
需要说明的是，在实际产品实现时，用户可点击压缩按钮613，手机100可响应该点击操作，自动选择压缩算法对图库应用进行压缩，即直接显示图6中的(d)所示界面630，无需用户选择压缩方式。
应理解，长按操作可以是在应用图标的位置长按预设时长(比如2秒)后，手机100才显示图6中(b)所示的界面610。
方式2：用户可以在系统设置中选择待压缩的应用及其对应的压缩方式。
示例1：如图7所示，假设用户在手机100的主界面点击设置应用图标，手机100可响应点击操作，进入设置应用界面，比如可参阅图7中的(a)所示的界面700，该界面700中可包括压缩设置选项701。接着，用户可点击压缩设置选项701进入压缩设置界面，比如可显示图7中的(b)所示界面710，用户可在界面710中选择要压缩的应用以及压缩方式。比如，用户选择图库之后，可继续在压缩方式中选择重度压缩。当用户点击重度压缩之后，手机100可对图库应用进行压缩，此时显示屏上可显示图7中的(c)所示界面720， 该界面720上可包括提示信息721，例如该提示信息721可以为：正在压缩图库应用以及压缩进度，比如图中所示的30％。用户可通过该提示信息看到压缩的进度，当压缩完成之后，手机可继续显示图7中的(b)所示界面710。
应理解，用户也可以在图7中的(b)所示界面710中选择多个应用进行压缩。当然，不同的应用可以选择相同或不同的压缩方式。
示例2：如图8所示，假设用户在手机100的主界面点击设置应用图标，手机100可响应点击操作，进入设置应用界面，比如可参阅图8中的(a)所示的界面800，该界面800中可包括压缩设置选项801。接着，用户可点击压缩设置选项801进入压缩设置界面，比如可显示图8中的(b)所示界面810，界面810中可包括每一个应用对应的多种压缩方式按钮，用户可通过选择压缩方式来选择应用。比如，用户可点击图库应用中的重度压缩按钮811，手机100可响应用户的点击操作，对图库应用进行压缩，例如可显示图8中的(c)所示界面820，该界面上可包括提示信息821，比如“正在压缩图库应用”以及压缩进度。当压缩完成之后，手机可继续显示图8中的(b)所示界面810。应理解，在该示例中，用户不需要单独选择应用，可以直接选择压缩方式以达到同时选择应用的目的。
需要说明的是，在实际应用中，也可以不显示图7中的(c)所示界面720以及图8中的(c)所示界面820。
在本申请另一些实施例中，在实际产品实现时，也可以不显示图7和图8所示界面上的三种压缩方式的按钮，仅显示一个“压缩”按钮，比如图4B所示的压缩按钮431。
S302：响应用户选择待压缩的应用以及对应的压缩方式的指令，按照选择的压缩方式对待压缩的应用进行压缩。
以图4A为例，假设用户在界面410中点击中度压缩方式按钮，手机100可响应该操作，对图库应用进行中度压缩，压缩之后的界面可参阅图4A中的(c)所示界面420。其中，界面420中可包括已压缩的应用图标和未压缩的应用图标。并且，已压缩的应用和未压缩的应用的应用图标不同。需要说明的是，当应用压缩之后，用户可通过界面上的图标样式或者文字信息等分辨出未压缩的应用和已压缩的应用。
应理解，在对应用进行压缩时，可以采用Lz4、lz4fast、zstd、deflate、gzip等算法进行压缩，在本申请实施例中能够对应用进行压缩的算法均可包含在本申请的保护范围内。
需要说明的是，上述选择应用的方式及用户界面仅是一种示意性说明，例如也可以在状态栏添加压缩按钮，这样用户可以直接从状态栏点击进入压缩设置界面等方式来选择要压缩的应用。并且，在实际产品实现时，界面上可以包括更多或更少的控件，本申请对此不作限定。
在一些实施例中，对应用进行压缩时，是对应用的安装数据和使用过程中产生的数据进行压缩。示例性的，在安卓系统中，这些数据的存储路径可以为：data/data/com.xxx.xx；data/app/com.xxx.xx；sdcard/Android/data/com.xx.xx。
另一示例，在鸿蒙系统中，这些数据的存储路径可以为如下路径：
(1)、/data/app/base/<bundlename>
(2)、/data/ce/<userId>/bundle/<bundlename>
(3)、/data/ece/<userId>/bundle/<bundlename>
(4)、/data/sece/<userId>/bundle/<bundlename>
(5)、/mnt/hmdfs/<userId>/device_view/local/data/<bundlename>/
通过上述实施例，用户可以根据自身的需求选择要压缩的应用以及应用的压缩方式，然后对应用进行压缩，能够节省电子设备的存储空间，提高空间利用率。并且，由用户选择要压缩的应用和压缩方式能够提升用户体验。
下面介绍由电子设备触发的应用压缩方法。如图9所示，为本申请实施例提供的另一种应用压缩方法流程图，参阅图9所示，该方法可包括如下步骤：
S901：确定满足预设压缩条件。
在一些实施例中，预设压缩条件可包括如下条件中的至少一种：
(1)、电子设备的存储空间剩余量小于设定阈值。比如，当存储空间的剩余量小于总存储空间的5％时触发应用压缩。
(2)、电子设备处于灭屏状态，或者用户未使用电子设备的情况。
(3)、电子设备的温度不超过设定温度，比如45摄氏度。
(4)、电子设备中的可压缩文件的大小超过设定阈值，比如超过10GB。
(5)、电子设备中可压缩文件压缩后的预估收益(即压缩后能节省出的空间大小)大于设定阈值，比如大于1GB。
(6)、电子设备的电量充足。比如电子设备的电量大于60％。
在一些实施例中，如果电量不足，可在电子设备的电池为充电状态，并且电量大于设定电量(比如，60％)时触发压缩。当然，设定电量也可以为其它数值，比如50％等，本申请对此不作限定。
S902：选择待压缩的应用及压缩方式。
作为一种可能的实现方式，电子设备可以根据用户使用应用的情况选择待压缩的应用。示例性的，电子设备可以选择用户使用比较频繁的应用作为待压缩的应用。当然，也可以选择不经常使用的应用作为待压缩的应用，本申请对此不作限定。
作为另一种可能的实现方式，电子设备可以根据应用所占的存储空间选择待压缩的应用。示例性的，电子设备可以选择占存储空间较大的应用作为待压缩的应用，比如可以将应用所占的存储空间进行排序，然后选择所占存储空间排在前N(N为正整数)位的应用作为待压缩的应用。
在一些实施例中，电子设备可以按照应用的使用情况选择压缩方式，比如经常使用的应用可以选择轻度压缩，偶尔使用的应用可以选择中度压缩，几乎不使用的应用选择重度压缩。应理解，经常使用的应用可以为在设定时间内的使用次数大于第一设定阈值的应用，偶尔使用的应用可以为在设定时间内的使用次数大于第二设定阈值，且小于第一设定阈值的应用，几乎不使用的应用为在设定时间内的使用次数小于第二设定阈值的应用。当然，针对不同的应用可以选择不同的压缩方式，也可以选择相同的压缩方式，本申请对此不作限定。
S903：按照选择的压缩方式对待压缩的应用进行压缩。
应理解，图9所示实施例中的S903和图3所示实施例中的S302相同，具体实现过程可参阅图3所示实施例的S302中的详细介绍，此处不再重复赘述。
以上实施例介绍了应用的压缩过程，下面分别基于上述几种选择压缩应用的方式介绍应用解压缩的过程。
示例1：如图10所示，假设用户选择了多个待压缩的应用，比如应用压缩后的界面如图10中的(a)所示界面1000，手机100可检测到用户在该界面1000上的手势操作，触发压缩后的应用进入编辑状态。
在一些实施例中，手势操作可以为用户在界面1000上的空白位置处的长按操作，手机100可响应用户的长按操作，显示图10中的(b)所示界面1010，该界面1010上可包括处于编辑状态的压缩应用的图标、解压缩的按钮1011，用户可在该界面1010上选择要解压缩的应用。比如，用户可在界面1010上选择压缩的图库应用(例如在压缩的图库应用的选择框上可显示√号标记)，然后点击解压缩的按钮1011，手机100可响应该点击操作，对图库应用进行解压缩，解压缩完成之后可参阅图10中的(c)所示界面1020。
示例2：如图11所示，对于应用压缩后的界面1100，手机100可检测到用户在该界面上的手势操作，比如手势操作可以为用户在图11中的(a)所示界面1100上对图库应用图标的长按操作，手机100可响应长按操作，显示图11中的(b)所示界面1110，该界面1110中可包括分享按钮1111、卸载按钮1112、解压缩按钮1113。用户可在界面1110上点击解压缩按钮1113，手机100可响应该点击操作，对图库应用进行解压缩。
应理解，上述两种示例仅是示意性说明，手势操作也可以为其它的操作，当然还可以为语音触发操作等。并且，本申请实施例中用户在选择待压缩的应用/解压缩的应用时可以选择多个应用进行批量压缩/解压缩。
示例3：如图12所示，假设手机100显示图12所示的(a)所示界面1200，该界面1200中可包括解压缩设置选项1201，当用户点击解压缩设置选项1201后，手机100可响应该点击操作，进入解压缩设置界面，例如显示图12中的(b)所示界面1210。其中，界面1210中可显示已压缩的应用列表，用户可在该界面中选择需要解压缩的应用，比如用户可勾选图库应用，然后点击解压缩按钮1211，手机100可响应对解压缩按钮1211的点击操作，对图库应用进行解压缩，例如可显示图12中的(c)所示界面1220。其中，界面1220中可包括提示信息1221，例如该提示信息可以为：正在解压缩图库应用以及解压缩进度条。用户可通过解压缩进度条看到解压缩的进度，当解压缩完成之后，可继续显示图12中的(b)所示界面1210。当然，在实际产品实现时，当解压缩完成之后，手机100也可以返回主界面等，本申请对此不作限定。
示例4：如图13所示，假设手机100显示图13所示的(a)所示界面1300，该界面1300中可包括压缩设置选项1301，当用户点击压缩设置选项1301后，手机100可响应该点击操作，进入压缩设置界面，例如显示图13中的(b)所示界面1310。其中，界面1310中可包括已压缩的应用列表和未压缩的应用列表。假设图库为已压缩的应用，当用户点击图库应用的解压缩按钮1311时，手机100可响应用户的点击操作，对图库应用进行解压缩，比如可显示图13中的(c)所示界面1320，该界面1320中可包括提示信息1321，例如该提示信息可以为：正在解压缩图库应用以及解压缩进度条。当压缩完成之后，手机100可显示图13中的(d)所示界面1330，在界面1330中图库应用所在的矩形框内的压缩标识发生了变化。
由于在压缩应用时并没有删除应用，因此本申请实施例中在对压缩的应用进行解压缩后可直接使用该应用，无需重新安装应用。
下面继续介绍应用压缩后用户如何使用压缩后的应用。
在一些实施例中，已压缩的应用可以边解压边启动，即应用可以正常启动，在解压缩过程中，文件系统可直接将解压缩之后的数据传递给应用，应用感知不到解压缩的过程，能够缩短时间，提升效率，并且能够提升用户体验。示例性的，如图14所示，假设手机100显示图14中的(a)所示的主界面1400，该界面1400中图库应用为已压缩的应用，当用户点击已压缩的图库的应用图标后，手机100可响应该操作，打开图库应用，显示图库的应用界面，例如显示图14中的(b)所示的界面1410。
在另一些实施例中，已压缩的应用可以先解压，在解压完成之后启动进入应用界面。即用户可以看到应用解压过程，等待解压完成后使用应用。示例性的，如图15所示，假设手机100显示图15中的(a)所示的主界面1500，该界面1500中图库应用为已压缩的应用，当用户点击已压缩的图库的应用图标后，手机100可响应该操作，对图库应用进行解压缩，例如可显示图15中的(b)所示的界面1510。其中，界面1510中可包括图库解压的提示信息1511，当解压完成后，可打开图库应用，显示图库的应用界面，例如显示图15中的(c)所示的界面1520。
对于上述各种示例出的对应用进行压缩或者解压缩的方法，还可以包括：响应于用户对已压缩的应用的应用图标的操作，改变对已压缩的应用的压缩方式。示例性的，比如已压缩的应用为图库应用，且图库应用为经过轻度压缩的应用。用户可以长按图库应用的应用图标，将轻度压缩方式更改为中度压缩方式，并对图库应用进行中度压缩。接着，用户可以长按经过中度压缩的图库应用的应用图标，将中度压缩方式更改为重度压缩方式，并对图库应用进行重度压缩。这样用户可以根据自身需求调整压缩方式，能够提升用户体验。
应理解，上述压缩方式的更改仅是一种示意性说明，本申请实施例中的压缩方式之间可以随意切换，比如也可以从轻度压缩方式更改为重度压缩方式，或者从中度压缩方式更改为轻度压缩方式，再从轻度压缩方式更改为重度压缩方式等，本申请对此不作限定。
