Detailed Description

In order to better understand the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the drawings and specific embodiments.

Nowadays, various applications related to life entertainment emerge in large quantities, and as the functions of the applications are more and more, the storage space occupied by the applications is larger and larger, and in order to meet the needs of life entertainment, a large number of applications are often installed on a terminal by a user, and application data occupy excessive storage space of the terminal, and in addition, if the user uses a certain application for a long time, the application also generates a large amount of user data.

At present, if data in the terminals are to be compressed, a user needs to search data to be compressed from a large amount of data, then compression software in the terminal is selected, and the terminal compresses the data according to the data selected by the user.

In view of this, an embodiment of the present application provides a method for compressing and decompressing data, and the following introduces an application scenario related to the embodiment of the present application.

The method for compressing and decompressing data in the embodiment of the present application may be executed by a terminal, where the terminal may be, for example, a mobile phone, a computer, and the like, and specifically may be implemented by a target application in the terminal, where the target application is, for example, a widget in the terminal, or a client pre-installed in the terminal, or a sub-application embedded in a third-party application in the terminal. Unlike the application, the gadget can realize the process of compressing and decompressing data without the support of a background server.

Referring to fig. 1, an application scenario diagram of a data compression and decompression method is shown, or may be understood as a structural example diagram of a terminal, where the terminal 110 includes a plurality of applications and an applet 120, and the plurality of applications include a first application 130 and a second application 140.

When the user wants to use the widget 120, the user may click on the target file box in the widget 120, and the terminal 110 displays the target file box on the main interface. Of course, the terminal 110 may create a plurality of object file boxes on one main interface of the terminal 110 or create one object file box on each main interface, respectively, in response to an operation by the user. Alternatively, the object file frame may be automatically generated by the widget 120, and the object file frame is displayed at a preset position of the terminal 110 without any operation by the user.

When a user needs to compress the application data of the first application 130, the application icon of the first application 130 may be moved to the target file frame, and when the terminal 110 detects that a new application icon exists in the target file frame, the application data corresponding to the application icon is obtained and compressed. The process of how to compress the application data will be described below.

When the user needs to use the first application 130, the application icon of the first application 130 may be moved out of the target file frame, and when the terminal 110 detects that a certain application icon is absent in the target file frame, the terminal acquires the compressed data corresponding to the application icon and decompresses the compressed data, thereby acquiring the application data and recovering the normal use of the application. The process of how to decompress the data will be described below.

Based on the application scenario discussed in fig. 1, a method for compressing data according to an embodiment of the present application is described below.

Referring to fig. 2, a flow chart of a data compression method is shown, the method including:

s201: and displaying the target file frame.

A plurality of application icons are displayed in the target file frame, so that a user can visually see the compressed application. One or more object file frames may be displayed on a main interface of the terminal 110, and each object file frame may also be displayed on each main interface. Of course, the target file box may be displayed at other positions of the terminal 110. The following describes an example of a manner in which the target file box is created and displayed:

firstly, the method comprises the following steps: the terminal 110 displays an object file box in response to a user's object manipulation with respect to the widget 120.

Specifically, the user presses the main interface of the terminal 110 for a long time, and the terminal 110 displays a setting interface including the widget 120 in response to the user's operation. The widget 120 may be displayed on a status bar. The widget 120 includes a target file frame corresponding to a target application in the terminal, the user drags or clicks the target file frame, and the terminal 110 displays the target file frame on the main interface in response to the dragging or clicking operation of the target file frame.

II, secondly: the terminal 110 is pre-installed with a target application, a user performs a target operation on the target application, and the terminal 110 creates a target file frame corresponding to the target application in response to the target operation. The target operation is, for example, a long-press operation of an icon of the target application.

Thirdly, the method comprises the following steps: the terminal 110 creates a target file frame in advance and displays the target file frame at a preset position of the main interface. For example, the application icon of the target application preinstalled in the terminal 110 is the target file box.

For example, fig. 3 shows a variation example diagram of a terminal interface in the process of creating a target file frame, wherein (1) in fig. 3 shows an example diagram of a setting interface on which a widget 120 is displayed, wherein a dotted arrow pointed to a desktop by the widget 120 indicates that a user drags or clicks the target file frame in the widget 120, the terminal 110 shows an example diagram of the target file frame as shown in (2) in fig. 3, and in the interface shown in (2) in fig. 3, the target file frame is displayed in a main interface of the terminal 110.

S202: and responding to a first operation of moving the application icon to the target file frame, and displaying a first prompt interface.

The application associated with the application icon is different from the application associated with the target file box. As discussed above, the target file frame is a target application corresponding to the compressed data, and the application icon refers to an icon of an application that the user wants to compress. When the user wants to compress the application data associated with the application icon, the user may drag or click the application icon, and the terminal 110 detects a first operation of the user moving the application icon to the target file box, such as a sliding operation, a dragging operation, and the like, and displays a first prompt interface. The first prompt interface is used for indicating a user to confirm whether to compress the application data corresponding to the application icon. The first prompt interface comprises a first key and a second key, the first key is used for confirming that application data corresponding to the application icon is compressed, and the second key is used for confirming that application data corresponding to the application icon is not compressed. The key may be an entity operation key, a touch key, a suspension key, or other keys, and is not limited in particular.

For example, fig. 4 shows an exemplary diagram of interface changes of a terminal during data compression, and (1) in fig. 4 shows an exemplary diagram of a main interface before data compression, which displays a first application 130, a second application 140, and a target file box. The dotted arrow pointing to the target file frame by the first application indicates that the user moves the icon of the first application 130 into the target file frame, the terminal 110 displays an exemplary diagram of the first interface as shown in (2) in fig. 4, where a "yes" icon displayed in the first interface represents a first key, a "no" icon represents a second key, when the user clicks the "yes" key, the user confirms that the application data corresponding to the application icon is compressed, and when the user clicks the "no" key, the user does not compress the application data corresponding to the application icon.

S203: and responding to the confirmation operation in the first prompt interface, and acquiring the application data associated with the application icon.

When the terminal 110 detects that the user clicks the first key, which is equivalent to the user performing an operation of confirming that the application data associated with the application icon is compressed, the terminal 110 acquires the application data associated with the application icon. For example, the terminal 110 prestores a corresponding relationship between each application icon and a storage address of the application data, and after the terminal 110 determines an application icon that needs to be compressed by a user, the terminal directly indexes the corresponding storage address according to the application icon. Of course, there may be one or more storage addresses corresponding to the application data of an application, and when there are multiple storage addresses, the terminal 110 obtains the corresponding data from the storage addresses respectively.

The application data refers to various layers of data related to the application, and specifically includes data of the application layer itself, for example, installation data of the application, and data of the user layer, for example, one or two of usage data of the application, the installation data of the application includes data generated in the process of installing the application, the installation data may also include an installation package of the application, and the usage data of the application includes personal account information of the user in the application, behavior data of the user is recorded, cache data generated in the process of using the application, and the like.

Data generated during the installation of the application, such as registration data of the application, a link of an application icon, and the like. The personal account information includes a login account, a login password, and the like. And recording behavior data of the user, for example, data related to historical operation behavior of the user in the application, such as web page addresses accessed by the user through the history of the application, and the like. The user uses the cached data generated during the application process, such as chat records, transmitted pictures, files, and the like.

When a user compresses an application, the user does not generally need to use the application, but does not exclude that the application still runs in the background, but the user wants to compress the application, at this time, the terminal 110 may forcibly close the application, and after forcibly closing the application, obtain application data of the application.

Certainly, the application data of a certain application cannot be compressed due to the permission problem, and then the terminal 110 may only obtain the data in the permission corresponding to the application to compress the data in the permission.

S204: and compressing the application data to obtain compressed data, and displaying the application icon in the target file frame.

As discussed above, the application data includes multiple levels of data, and the data corresponding to each level may be composed of multiple files, or the multiple levels of data of the application data may be composed of multiple files. For example, the installation data of the application may be composed of a plurality of files such as a registry of the application, a link of an application icon, and the like, or the installation data of the user is one file and the usage data of the user is one file. Since each file may have different format, during the compression process, the format corresponding to each file is stored so as to be decompressed and restored to the file type before compression.

When compressing the application data, the terminal 110 may compress each file included in the application data to obtain a plurality of compressed data packets, and then compress the plurality of compressed data packets to obtain final compressed data. The compression process is the same whether compressing a file or compressing a data packet, and the following description will be given by taking compressing a file as an example:

the current string is read. The current character string refers to a character string that the terminal 110 needs to compress currently, and any character that needs to be processed can be regarded as the current character string.

If the current character string is the character string read for the first time, and the character string read for the first time means that the current character string does not appear in the process of reading the file before, the terminal 110 encodes the current character string by using an identifier, wherein the identifier is used for indicating that the current character string is the character string read for the first time, and the identifier is related to the length of the current character string.

If the current character string is the character string read for the nth time, N is an integer greater than or equal to 2, and the character string read for the nth time indicates that the current character string appears in the process of reading the file before, the terminal 110 encodes the current character string by using a finger-back distance and a repetition length to obtain compressed data, wherein the finger-back distance is a distance offset between the current character string and the character string read for the (N-1) th time, and the repetition length is the length of the current character string.

For example, when a character string in a certain file to be compressed is "AABAABAAB", and "AAB" is read, the "AAB" does not appear in the previous process of reading the file, and the "AAB" is determined to be the character string read for the first time, and the encoding result of the "AAB" is: "(03) h, AAB", etc., wherein (03) h is an identifier. When "aabab" is processed, it is found that "AAB" appears during the previous reading of the document, the length of "aabab" is 6, so the repetition length is 6, the distance between the first character "a" in "aabab" and the first character "a" in "AAB" appearing before is 3, so the finger-back distance is 3, and "aabab" is represented by "(03) h, (06) h", according to the finger-back distance and the repetition length, so the encoding result of the character string "aababaab": "(03) h, AAB, ((03) h, (06) h)".

In a possible embodiment, it is determined whether the current character string is the character string read for the nth time, and character comparison may be performed one by one in a sliding window manner.

In a possible embodiment, an lzo (lempel Ziv obeshumer) algorithm is adopted in the data compression process, the first read character string is stored in a hash table, the first read character string and the position of the first read character string are stored in the hash table, when the current character string is read each time, whether the current character string is the nth read character string is judged according to whether hash collision occurs, and the hash collision indicates that the values obtained after hash operation of different character strings are the same. An example of the process by which the LZO algorithm compresses a string is as follows:

and reading the current character string, and carrying out Hash operation on the current character string.

And if the first hash operation does not generate hash collision, determining that the current character string is the character string read for the Nth time, and encoding the current character string by using the back pointing distance and the repetition length.

And if the first hash operation generates hash collision, performing the second hash operation, if the second hash operation does not generate collision, determining the current character string as the character string read for the Nth time, and encoding the current character string by using the finger-back distance and the repetition length.

And if the second hash operation still generates hash conflicts, determining the current character string as the character string read for the first time, encoding the current character string by using the identifier, writing the current character string into the hash table, and expanding the dictionary to reduce the time for searching the longest matching string each time, wherein the process for searching the longest matching string is the process for searching the character string read for the Nth time.

For example, when the character string "AABAABAAB" to be processed is read as "AAB", it is a new character string, and after the hash operation, the obtained position is stored in the hash table, and "AAB" is encoded with an identifier, that is, "(03) h, AAB". When the AABAAB is read again, determining the AABAAB as a character string read for the Nth time through the first hash operation if no hash collision is generated, namely repeating the character string with the previous character string, and coding the AABAAB by using a finger-back distance and a repetition length, namely, ((03) h, (06) h); if hash collision is generated, performing hash operation for the second time, if no collision is generated in the hash operation for the second time, determining that the AABAAB is the character string read for the Nth time, and encoding the current character string by using the finger-back distance and the repetition length, namely, ((03) h, (06) h); and if the hash collision is still generated in the second hash operation, determining the AABAAB as the character string read for the first time, encoding the current character string by using the identifier, writing the AABAAB into the hash table, and expanding the dictionary.

For example, with continued reference to fig. 4, after the user clicks the "yes" button in (2) of fig. 4, the terminal 110 displays an example of an interface of the terminal after the compression is completed as in (3) of fig. 4, and in the interface shown in (3) of fig. 4, an application icon of the first application 130 that has been compressed is displayed in the target file box.

As an embodiment, S202 in fig. 2 is an optional step.

As an embodiment, after compressing the application data corresponding to the application icon, or detecting that the user moves the application icon into the target file frame, the terminal 110 deletes the application icon that was previously and independently displayed in the terminal 110, that is, the application icon is displayed in the target file frame and is not displayed elsewhere.

After repeating the above steps for multiple times, multiple application icons are stored in the target file frame, and the terminal 110 may adjust or further sort the application icons according to the relevant operations of the user on the icons.

For example, the target file frame includes a first application icon and a second application icon, when the user wants to sort the first application icon and the second application icon, the user may move the first application icon, and the terminal 110 detects that the distance between the first application icon and the second application icon in the target file frame is less than or equal to a first threshold, creates a subfile frame in the target file frame, where the subfile frame includes the first application icon and the second application icon.

For example, fig. 5 shows an example of interface change of a terminal during application classification of a target file frame, and (1) in fig. 5 shows an example of an interface before application classification of the target file frame, in which a first application icon and a second application icon are displayed. The dotted arrow pointing to the second application from the first application indicates that the user moves the first application icon so that the distance between the first application icon and the second application icon is less than or equal to the first threshold, and the terminal 110 displays an example of the interface after application classification of the target file box shown as (2) in fig. 5, in the interface shown as (2) in fig. 5, the target file box displays a subfile box in which the first application icon and the second application icon are displayed.

Or, when the user wants to move the second application icon to the position of the first application icon, the user may move the first application icon, and the terminal 110 detects that the distance between the first application icon and the second application icon in the target file frame is less than or equal to a second threshold, and then exchanges the position of the second application icon with the position of the first application icon, where the first threshold is less than the second threshold.

For example, fig. 6 shows an example of an interface change of a terminal during application shift of a target file frame, and (1) in fig. 6 shows an example of an interface before application shift of the target file frame, in which a first application icon and a second application icon are displayed. The dotted arrow pointing to the second application from the first application indicates that when the user moves the first application icon so that the distance between the first application icon and the second application icon is less than or equal to the second threshold, the terminal 110 displays an example image of the interface after the application shift of the target file frame shown in (2) in fig. 6, and in the interface shown in (2) in fig. 6, the position of the second application icon and the first application icon have been interchanged.

In a possible embodiment, when a user wants to use an application in the target file frame, an operation of moving the application icon out of the target file frame may be performed, and the terminal 110 detects the operation, acquires compressed data corresponding to the application icon, and decompresses the compressed data, thereby acquiring application data of the application. Further, after the application data is decompressed, the application icon in the target file frame may be deleted and independently displayed in the main interface of the terminal 110.

Based on the same inventive concept, please refer to fig. 7, which shows a flowchart of a data decompression method, the method includes:

s701: and responding to a second operation of moving the first application icon out of the target file frame, and displaying a second prompt interface.

When the user wants to use the first application 130, the user drags or clicks the application icon, the terminal 110 detects a second operation of the user to move the application icon out of the target file box, the second operation being, for example, a sliding operation, a dragging operation, etc., and displays a second prompt interface. And the second prompt interface is used for indicating whether to confirm whether to recover the application data corresponding to the application icon. The second prompt interface comprises a third key and a fourth key, the third key is used for confirming recovery of application data corresponding to the application icon, and the fourth key is used for confirming deletion of the application data corresponding to the application icon. The key may be an entity operation key, a touch key, or various keys such as a suspension key, which is not limited specifically.

For example, fig. 8 shows an exemplary diagram of an interface change of the terminal during data decompression, and (1) in fig. 8 shows an exemplary diagram of a compressed object file box, which displays the first application 130. The dotted arrow pointing to the desktop by the first application 130 indicates that the user moves the icon of the first application 130 out of the destination file box, the terminal 110 displays an exemplary diagram of a second interface as shown in (2) in fig. 8, the "resume" icon displayed in the second interface represents a third key, the "delete" icon represents a fourth key, when the user clicks the "resume" key, the user confirms that the compressed data corresponding to the application icon is restored, and when the user clicks the "delete" key, the user confirms that the compressed data corresponding to the application icon is deleted.

S702: and in response to the recovery operation performed on the second prompt interface, acquiring the compressed data associated with the application icon.

When the terminal 110 detects that the user clicks the third key, which is equivalent to the user performing an operation of confirming recovery of the application data corresponding to the application icon, the terminal 110 obtains the compressed data associated with the application icon. The compressed data includes one or both of installation data of the compressed application or usage data of the compressed application.

Further, in response to the confirmation performed on the second prompt interface not to resume the operation, the application icon and the compressed data associated with the application icon are deleted.

When the terminal 110 detects that the user clicks the fourth key, which is equivalent to the user performing an operation of confirming that the application data corresponding to the application icon is not recovered, the terminal 110 deletes the application icon and the compressed data associated with the application icon.

S703: and decompressing the compressed data to obtain application data, and deleting the first application icon in the target file frame.

As discussed above, the compressed data is obtained by compressing a plurality of compressed data packets, and when decompressing the compressed data, the terminal 110 first obtains a plurality of compressed data packets, and then decompresses each compressed data packet to obtain the application data. The decompression process is the same whether the compressed data or the data packet is decompressed, and the decompression of a certain data packet is taken as an example and described as follows:

the current encoded value is read. The current code value refers to a code value that the terminal 110 needs to decompress currently, and any character that needs to be decompressed can be regarded as the current code value.

And if the current coded value contains the identifier, determining that the character string corresponding to the current coded value is the character string read for the first time, and decoding the current coded value according to the identifier.

If the current code value contains a back-pointing distance and a repetition length, determining that a character string corresponding to the current code value is an Nth read character string, wherein N is an integer greater than or equal to 2, the Nth read character string indicates that the current character string appears in the process of reading the file before, finding the Nth read character string by the terminal 110 according to the back-pointing distance, and then obtaining the character string corresponding to the current code value according to the repetition length, wherein the back-pointing distance is a distance offset between the character string corresponding to the current code value and the character string read in the (N-1) th time, and the repetition length is the character string length corresponding to the current code value.

For example, when the character string of the compressed data to be decompressed is "(03) h, AAB, ((03) h, (06) h)", and the identifier "(03) h" is read, the 3 characters "AAB" following the identifier are determined as the character string read for the first time. When the "((03) h, (06) h)" is read, the character string corresponding to the "((03) h, (06) h)" is determined to be the character string read for the nth time, the character string "AAB" read for the (N-1) th time is found according to the distance 3, and the character string corresponding to the "((03) h, (06) h)" is obtained to be the "AABAAB" according to the length 6, so that the decoding result of the "((03) h,010110, ((03) h, (06) h)" is the "AABAABAAB".

For example, with continued reference to fig. 8, after the user clicks the "resume" button in (2) of fig. 8, the terminal 110 displays an exemplary diagram of a main interface after decompression is completed as in (3) of fig. 8, in which an application icon and a target file box of the first application 130 are displayed.

In one possible embodiment, a plurality of application icons are stored in the target file frame, and the terminal 110 may adjust or further arrange the application icons according to the user's associated operations on the icons.

Or, when the user wants to move the second application icon to the position of the first application icon, the user may move the first application icon, and the terminal 110 detects that the distance between the first application icon and the second application icon in the target file frame is less than or equal to a second threshold, moves the position of the second application icon to the position of the first application icon, and moves the first application to the right by one position, where the first threshold is less than the second threshold.

After the terminal 110 decompresses the compressed data associated with a certain application icon, the application icon is independently displayed in the main interface of the terminal 110 to indicate that the application can be normally used, and the deletion of the application icon in the target file frame indicates that the compressed data associated with the application icon has been deleted.
