Example one
Based on the foregoing embodiments, the embodiments of the present invention provide a method for deleting cached data, where the method may be applied to a terminal, a function implemented by the method for deleting cached data may be implemented by a processor in the terminal calling a program code, and of course, the program code may be stored in a computer storage medium, and thus, the terminal at least includes the processor and the storage medium.
Fig. 3 is a schematic flow chart of a method for deleting cache data according to a first embodiment of the present invention, and referring to fig. 3, the method for deleting cache data may include:
s301: acquiring a system log of a terminal;
specifically, when a user of a terminal uses the terminal, the user can use a third-party application installed in the terminal when the user finds that the system is not smoothly used and a card pause phenomenon occurs, fig. 4 is a schematic configuration diagram of a display interface for clearing cache data in the first embodiment of the present invention, as shown in fig. 4, the third-party application is a mobile phone manager, and a virus in the mobile phone is checked and killed by the mobile phone manager, specifically, the virus includes payment risk, hidden danger software, malicious software and system bugs, and the cache data in the smart phone is cleared.
In addition, when a user of the terminal plays a game, the size of the installation package of the game is 600M, but the user of the terminal frequently plays the game so that the occupied memory of the game reaches 1G, then, the user can unload the game in order to continue playing the game, and then download the installation package of the game again, so that the operation of the user is complicated.
In order to simplify the problem of complicated operation steps, a system log of the terminal may be obtained first, in practical applications, in the obtaining of the system log of the terminal, the system log may be generated and stored by tracking the systree by the system, the terminal obtains the system log of the terminal in real time, and changes of various parameters in the system log are monitored to determine whether the system is stuck or is about to be stuck.
Here, when the terminal is in an operating state, the terminal may generate a system log through sysstrace, the system log records information of hardware, software and system problems in the system, and may also monitor events occurring in the system, and through the system log, the cause of the terminal error occurrence may be checked, or traces left by an attacker when the terminal receives an attack may be found.
Therefore, the system log records the operating condition of the system, and then, in order to clean the cache data, the system log of the terminal may be first obtained.
The terminal may be an electronic device with information processing capability, such as a smart phone, a tablet computer, or a desktop computer, and the embodiment of the present invention is not limited in particular.
S302: acquiring the frame rate of a display screen of the terminal from a system log;
after the system log of the terminal is acquired in S301, since information of hardware, software, system problems in the system and events occurring in the system are recorded in the system log, and when the system is jammed, the capability of the terminal for processing information is reduced, so that the frame rate of the display screen of the terminal is changed correspondingly when the system is jammed, the frame rate of the display screen of the terminal is acquired from the system log.
The frame rate of the display screen can reflect the current display condition of the display screen, and then the display condition of the terminal can be known through the frame rate of the display screen in the system log, so that whether the system is blocked or not can be monitored in real time by acquiring the frame rate of the display screen.
S303: when the frame rate of a display screen is determined to meet a preset condition, determining cache data to be deleted from the cache data of the terminal;
specifically, the display condition of the terminal can be known through the acquired frame rate of the display screen, whether the frame rate of the display screen meets the preset condition or not is judged through the set preset condition, and only if the preset condition is met, the cache data to be deleted is determined from the cache data of the terminal.
When the frame rate of the display screen meets the preset condition, the fact that the system of the terminal is blocked due to the fact that the cache data occupy more storage space in the system of the terminal is shown, and therefore the cache data to be deleted are determined from the cache data of the terminal at the moment; when the frame rate of the display screen is determined not to meet the preset condition, the system running state of the terminal is good, and the cache data does not need to be cleaned at the moment.

Example two
Based on the foregoing embodiments, this embodiment provides a method for deleting cached data, where the method may be applied to a terminal, and a function implemented by the method for deleting cached data may be implemented by a processor in the terminal calling a program code, where of course, the program code may be stored in a computer storage medium, and thus, the terminal at least includes the processor and the storage medium.
On the basis of the first embodiment, in order to determine whether the system of the terminal has a stuck phenomenon or is about to have a stuck phenomenon, the determination may be made by whether the frame rate of the display screen satisfies a preset condition, and in an alternative embodiment, the determining that the frame rate of the display screen satisfies the preset condition in S303 may include:
and when the frame rate of the display screen is determined to be greater than or equal to a first preset threshold, determining that the frame rate of the display screen meets a preset condition.
Because the frame rate of the display screen can reflect the number of display frames in a unit time, when the frame rate of the display screen is too large, it indicates that the number of display frames in the unit time is large at this time, and the terminal is currently in a high-speed operation state, for example, a user of the terminal is playing a game or browsing a high-definition video, and the like, a large amount of buffer data is generated at this time, and if the large amount of buffer data is not timely cleaned, a system of the terminal is stuck.
Therefore, by setting the first preset threshold, it is determined that the frame rate of the display screen is greater than or equal to the first preset threshold, and it can be determined that the terminal is in a high-speed operation state, and the cache data needs to be cleaned in time, so as to prevent the system from generating a pause phenomenon.
In an alternative embodiment, the determining that the frame rate of the display screen satisfies the preset condition in S303 may include:
determining the variation of the frame rate of the display screen in unit time;
and when the variation is determined to be larger than or equal to a second preset threshold, determining that the frame rate of the display screen meets a preset condition.
The frame rate of the display screen at the current time is acquired, the frame rate of the display screen at the previous time is acquired, the variation of the frame rate of the display screen in unit time is determined according to the frame rate at the current time and the frame rate at the previous time, and then the frame rate of the display screen is determined to meet the preset condition by comparing the variation of the frame rate of the display screen in unit time with the second preset threshold value.
Specifically, when the amount of change is determined to be large, it indicates that the frame rate of the display screen is changed from a large value to a small value, for example, the frame rate of the display screen is 60fps at the current time, 30fps at the next second, and the second preset threshold is 20fps, and obviously, when the amount of change is determined to be greater than or equal to the second preset threshold, it indicates that the frame rate of the display screen is reduced, the terminal has a stuck phenomenon, and it is determined that the frame rate of the display screen meets the preset condition, and it is necessary to clean the cache data.
In order to determine the cache data to be deleted from the buffer data to prevent the system from generating a stuck phenomenon, in an alternative embodiment, the determining the cache data to be deleted from the cache data of the terminal in S303 may include:
determining the calling frequency of the cache data;
and determining the cache data with the calling frequency less than the preset frequency as the cache data to be deleted.
The cache data may include contents such as a browsing plug-in, a push message, and an error report, and the embodiment of the present invention is not limited in particular.
Specifically, the calling frequency of each cache data is determined, and in consideration of the influence of the calling frequency of each cache data on the system running speed, the cache data with the calling frequency lower than the preset frequency can be determined as the cache data to be deleted, that is, the cache data which is not frequently used in the cache data is determined as the cache data to be deleted, and the cache data with the higher calling frequency is reserved.
In order to determine the calling frequency of each cache data, in an alternative embodiment, determining the calling frequency of the cache data may include:
obtaining the calling times of the cache data from the system log;
and determining the calling frequency of the cache data according to the calling times.
Specifically, since the system log records the call record of each cache data, the call frequency of each cache data can be counted, the call frequency of each cache data can be determined according to the call frequency of each cache data in a preset time period before the current time, and then the cache data to be deleted is selected according to the call frequency of each cache data; the cache data to be deleted can be selected directly according to the calling times of each cache data.
In order to determine, from the cache data, cache data to be deleted to clean the cache data, in an optional embodiment, determining, as the cache data to be deleted, the cache data whose calling frequency is less than a preset frequency may include:
selecting cache data with a data type of push information from the cache data with calling frequency less than preset frequency;
acquiring a receiving label of a push message;
and determining the cache data except the push message which is actively received by the selected receiving tag in the cache data with the calling frequency less than the preset frequency as the cache data to be deleted.
Specifically, cache data with a calling frequency smaller than a preset threshold value is selected first, the selected cache data may include cache data with a data type of push message, and the push message may be divided into two types according to a receiving tag of the push message, where one type is a push message with an actively received receiving tag, and the other type is a push message with a passively received receiving tag.
The active receiving is used for receiving the push message after the identification terminal receives the receiving permission instruction, and the passive receiving is used for identifying that the terminal does not receive the receiving permission instruction to receive the push message.
For example, the push message whose receiving tag is actively receiving may be a message received through communication software, fig. 5 is an optional arrangement schematic diagram of a display interface of the push message in the second embodiment of the present invention, as shown in fig. 5, the push message is a wechat picture and a wechat video sent by a wechat, and the push message is received by the terminal only after the user sends a receiving permission instruction;
wherein, the push message whose receiving tag is passively received may be an advertisement window pushed by a third party application, fig. 6 is another optional arrangement schematic diagram of a display interface of the push message in the second embodiment of the present invention, as shown in fig. 6, after the shopping software is opened, an advertisement window pushed by a server on the network side of the shopping software, for example, the XX advertisement in fig. 6: "buy XX product at present stage, buy and buy immediately as long as 998, get preferential" the push message is a push message which is forcibly received by the terminal after the user does not issue the instruction to allow reception.
In order to avoid deleting the push message actively received by the user, the cache data with the calling frequency less than the preset frequency, except the selected receiving tag as the cache data of the push message actively received, is determined as the cache data to be deleted, so that the push message actively received by the user in the cache data with the calling frequency less than the preset frequency is reserved, and the data required to be reserved by the user is prevented from being deleted by mistake or mistakenly deleted.
In an optional embodiment, determining cache data to be deleted from the cache data of the terminal includes:
selecting cache data with the data type of a push message from the cache data;
acquiring a receiving label of a push message;
determining a receiving tag of the push message as passively received cache data from the selected cache data with the data type of the push message as first cache data to be deleted;
determining the calling frequency of the cache data except the first cache data to be deleted;
selecting cache data with calling frequency less than preset frequency from the cache data except the first cache data to be deleted, and determining the cache data as second cache data to be deleted;
and forming the cache data to be deleted by using the first cache data to be deleted and the second cache data to be deleted.
Here, in order to delete the cache data that is useless to the user as much as possible, first, the number of cache users to be deleted is determined from the cache data whose data type is the push message, and then the second cache data to be deleted is determined from the cache data other than the first cache data to be deleted, so that the cache data to be deleted is formed by the first cache data to be deleted and the second cache data to be deleted.
In a specific implementation process, in order to determine the first cache data to be deleted, the cache data of which the data type is the push message is selected from the cache data, then, a receiving tag of the push message is obtained, and the receiving tag of the push message is the passively received cache data and is determined as the first cache data to be deleted from the cache data of which the selected data type is the push message.
In a specific implementation process, in order to determine first cache data to be deleted, cache data other than the first cache data to be deleted is recorded as remaining cache data, the calling frequency of the cache data other than the first cache data to be deleted is determined, then cache data with the calling frequency smaller than a preset frequency is selected from the cache data other than the first cache data to be deleted and determined as second cache data to be deleted, and therefore cache data which are not frequently used in the remaining cache data can be deleted, and a storage space is released.
And finally, the first cache data to be deleted and the second cache data to be deleted are used for forming the cache data to be deleted, so that the push messages which do not need to be reserved by the user are deleted, the cache data which are not frequently used in the rest cache data are deleted, the storage space is released to the maximum extent, and the system is prevented from being blocked.
The method for deleting the cache data comprises the steps of firstly, obtaining a system log of a terminal, then obtaining a frame rate of a display screen of the terminal from the system log, obtaining the frame rate of the display screen, knowing an operation condition of the system through display changes of the display screen, determining a time for cleaning the cache data by setting a preset condition when the frame rate of the display screen meets the preset condition, and finally determining the cache data to be deleted from the cache data of the terminal and deleting the cache data to be deleted; that is to say, in the embodiment of the present invention, the operating condition of the system can be known through the obtained frame rate of the display screen, and further, under the condition that the frame rate of the display screen meets the preset condition, the cache data to be deleted, that is, the cache data to be deleted, can be determined from the cache data, and then the cache data to be deleted is cleaned.
