Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.
Example one
Referring to fig. 2, it is shown that an embodiment of the present invention provides a method for a terminal to clean a cache, where the method may include:
s201: acquiring user participation degrees corresponding to cache files with different granularities according to a preset user participation degree acquisition strategy;
s202: comparing the user participation degree of the cache file with a preset threshold value: when the user participation degree of the cache file is lower than a preset threshold value, turning to S203; when the user participation degree of the cache file is higher than a preset threshold value, turning to S204;
s203: deleting the cache file;
s204: and saving the cache file.
For the technical solution shown in fig. 2, it should be noted that, in the running process of the application program of the terminal, a cache file is generated, generally, many cache files are generated by the application programs such as the instant messaging software and the network video playing software, and the size of the cache file is also large, so that, in this embodiment, the instant messaging software and the network video playing software are taken as examples for description, it can be understood that a person skilled in the art may apply the technical solution of this embodiment to a scenario of performing cache cleaning on other types of application programs without creative labor, and this embodiment is not described in detail.
In this embodiment, the user engagement of the cache file may be used to characterize the degree of correlation between the cache file and the user; specifically, the occurrence of the user-related information in the cache file can be used for representing, the more frequently the user-related information occurs, the more relevant the cache file is to the user, and further, the more important the cache file is to the user, so that the cache file needs to be saved when the cache is cleared.
In addition, the cache file may include a single cache file and a cache folder holding a plurality of cache files according to file granularity.
Optionally, when performing cache cleaning on a single cache file, step S201 may include:
and when the granularity of the cache file is any cache file, taking the ratio of the occurrence times of the user information in the cache file to the number of cache information pieces as the user participation degree corresponding to the cache file.
In a preferred implementation process, taking instant messaging software as an example, the ratio of the number of occurrences of the user information to the number of pieces of the cached information includes: in the chat records, the ratio of the number of the chat records with the user information to the total number of the chat records is shown.
Specifically, the user information may include an identifier of the user, and a keyword string corresponding to the user identity, such as a mobile phone number, an email address, and the like. Therefore, the chat record in which the user information appears may be a chat record including the user identifier and the keyword string corresponding to the user identity, or may also be a chat record sent by the user, and so on, which is not described in this embodiment.
In another preferred specific implementation process, taking network video playing software as an example, the ratio of the number of occurrences of the user information to the number of pieces of the cache information includes: the ratio of the playing times of the playing cache file to the total times of the video playing software playing the video.
Specifically, in network video playing software, a cache file is usually a video stream that is cached when a video is played, and therefore, the corresponding cache file is a play record of a user when each video is played; when the number of playing times of the video corresponding to a certain cache file is large, it indicates that the video is important for the user, and therefore, the cache file of the video should be saved.
Optionally, when performing cache cleaning on a cache folder storing a plurality of cache files, step S201 may include:
and when the granularity of the cache file is the cache folder of any application program, taking the use frequency of the application program as the user participation degree corresponding to the cache folder of the application program.
Specifically, each application program generates a corresponding cache folder in a storage space of the terminal, so as to store a cache file generated when the application program runs. When the application is frequently used, it is stated that the application is important for the user, and therefore, the cache file in the cache folder of the application is also important for the user, and therefore needs to be saved.
The embodiment provides a method for clearing cache by a terminal, which represents the importance of a cache file to a user through user participation, so that the cache file which is not needed by the user can be efficiently and automatically deleted, the cache file which is important to the user is reserved, the operation of the user is reduced, and the user experience is improved.
Example two
Based on the foregoing embodiment, the flow of the foregoing embodiment is described in detail by taking instant messaging software of a terminal as an example, referring to fig. 3, and the specific flow may include:
s301: traversing the cache file of the instant messaging software by the terminal;
specifically, the cache file in the instant messaging software generally stores chat records of users, different cache files correspond to different chat objects, and the chat objects may be single contacts or chat groups, which is not specifically limited in this embodiment.
S302: the terminal acquires the occurrence times of the user information and the total number of the chat records of the cache files in each cache file;
specifically, in the chat record corresponding to each cache file, when the user is more actively engaged in the chat record, the number of occurrences of the user information in the cache file is increased, and thus, the cache file of the chat record is more important for the user.
For example, taking the user name John as an example, in the chat record shown in fig. 4, the user does not participate in the chat, and the user information does not appear in the chat record, so that the chat record is considered to be unimportant to the user John, and the cache file of the chat record can be cleared when the cache is cleared;
still taking the user name John as an example, in the chat records shown in fig. 5, the user participates in the chat, so the user name and the chat records of the user appear in the chat records many times, so the chat records can be considered to be important for the user John, and the cache files of the chat records are saved when the cache is cleared;
still taking the user name John as an example, in the chat record shown in fig. 6, although the user does not participate in the chat, the user name appears in the chat record, so that the chat record can be considered as important for the user John, and the cache file of the chat record can be saved when the cache is cleared;
s303: the terminal obtains the ratio of the occurrence frequency of the user information to the total number of the chat records of the cache file;
s304: the terminal compares the ratio with a preset ratio threshold: when the ratio is not less than the preset ratio threshold, go to S305; when the ratio is greater than the preset ratio threshold, go to S306;
specifically, for S303 and S304, in the above description, it is assumed that m chat records are shared in a cache file of chat records, and n chat records in which user information is present, the ratio of the number of occurrences of user information as user participation to the total number of chat records in the cache fileSetting a preset ratio threshold value as a, wherein the preferred value of a is 30, and the method can be customized by a user;
if Q is larger than or equal to a, the chat records are proved to have great relation with the user, and the cache is reserved when being cleaned;
if Q < a, it shows that the chat record is not related to the user, and the cache can be cleared.
S305: the terminal marks the cache file as an unclonable identifier;
s306: the terminal marks the cache file as a cleanable identifier;
s307: and the terminal cleans the cache file corresponding to the cleanable identifier and stores the cache file corresponding to the unclonable identifier.
Optionally, in the specific implementation process of S305, S306, and S307, the terminal may further mark only the cache file that needs to be cleaned as a cleanable identifier, so that the terminal deletes the cache file with the cleanable identifier; or the terminal may further mark the cache file that needs to be stored as the unclonable identifier, so that the terminal deletes the cache file that does not have the unclonable identifier, which is not described in detail in this embodiment.
According to the embodiment, through a specific implementation process, the importance of the cache file to the user is represented through the user participation degree, so that the cache file which is not needed by the user can be deleted efficiently and automatically, the cache file which is important to the user is reserved, the operation of the user is reduced, and the user experience is improved.
