Specific embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in accompanying drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure and should not be by embodiments set forth here
Limited.On the contrary, there is provided these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure
Complete conveys to those skilled in the art.
As previously described, for the situation that application file is expired or invalid, if also still caching these application files, meeting
The waste to terminal storage space is caused, terminal response speed can be also affected when serious.In this regard, the embodiment of the present invention provides a kind of
The method processed application file, by server controls process order is issued, and instruction terminal carries out the place of application file
Reason.In addition, in preferred embodiment, the mode of application file is cleared up herein in connection with terminal local, inactive application is cleaned out in time
File.
Referring to Fig. 1, for a kind of method processed application file that the present invention is provided.
S101：Terminal receives the application file process order that application server sends.
Application file process order, refers to the instruction processed application file, for example, file is carried out the behaviour such as deleting
The instruction of work.Application file, refers to the associated documents of application program, for example, the configuration file of application program, the fortune of application program
Style of writing part, etc., wherein, configuration file is usually related to the version information of application program, upgrade information or user profile
File, and the operating file of application program refers to application program related file of recalls information in running.
In practical operation, application server sends application file and processes opportunity of order and do not limit to terminal, for example, can be with
Periodically issue application file and process order, or application file is issued as needed in technical attendant and process order, Huo Zhe
Version updating is carried out to application or application file is issued when deleting legacy version to process order, or terminal to report certain/a bit should
Order is processed with application file is issued when file is invalid.The application file processes order includes the text that instruction terminal is processed
Part identifies (such as file name) and processes action type.
In order to ensure terminal receives the application file process order that application server is issued, need to maintain terminal with application
Communication connection between server.For example, two can be maintained by way of terminal periodically sends heartbeat packet to application server
Communication connection between person.Specifically, terminal periodically to application server send heartbeat packet, heartbeat packet carried terminal IP address,
Terminal device information；Application server receives heartbeat packet, it is determined that keep communicating with terminal, so as to practical writing can be sent to terminal
Part process order.
It can be seen that, if it is desired to can implement by server lower section control life during application server and terminal communication
Order, now needs the heartbeat packet for maintaining and server.Heartbeat packet is mainly terminal periodically to server one sky of transmission
Order ensures that the connection of terminal and server will not disconnect because of time-out.Firstly, because process in terminal and server communication
In, if service end long-time does not receive the message of terminal, service end in order to discharge the resource that the terminal takes can disconnect with
The connection of terminal.If server and terminal are disconnected connection, then later terminal just cannot and server communication, if it is desired to
Continue to communicate, terminal must re-establish connection, but this process for setting up connection is very time-consuming, in order to solve this
Problem terminal can be solved by sending heartbeat packet.Next, terminal periodically sends heartbeat packet, and (heartbeat packet content carries client
Some essential informations, such as terminal mac address, device-dependent message, cell-phone number etc., main purpose is exactly and server carries out one
Secondary traffic operation), server finds that terminal periodically has and oneself communication, and server will be considered that terminal has always a demand for service, now
Server will not disconnect the connection with terminal.In addition, there is the transmission of heartbeat packet, it becomes possible to ensure terminal and server well
Connection do not turn off.
S102：Terminal parsing application file processes order, knows pending file identification and processes action type.
Pending file identification can be file name either file exclusive identification code or other represent files information,
Process mode of operation of the action type instruction to pending file is processed, for example, processing operation includes deletion action, updates operation
(old edition presents is replaced with new edition file), etc..
Specifically, server sends application file and processes order based on HTPP agreements to terminal, and for example, terminal receives application
The application file based on http protocol JSON forms that server sends processes order；Terminal parsing application file processes order
Mode is：Application file is parsed by FASTJSON modes and processes order.Wherein, JSON (JavaScript Object
Notation) it is a kind of data interchange format of lightweight, its a subset based on ECMAScript, JSON is using completely solely
Stand on the text formatting of language, but also using similar to C language family custom (including C, C++, C#, Java,
JavaScript, Perl, Python etc.).FASTJSON is the JSON processors that Java language is write, compared with JSON,
FASTJSO has the faster advantage of processing speed.
For example, the structure of application file process order is as follows：
{
"fileName":"myConfig.xml",
"fileOperation":"delete",
}
Wherein：
fileName：Expression needs to be deleted in file name, this example and needs to be deleted the title of file and be
myConfig.xml。
fileOperation：It is the operation for needing to carry out this file, the particular content of this operation is that delete is represented
Need to carry out deletion action to this file.
Such as above example, application file process order is that the data transfer of JSON forms is come by http protocol,
Terminal is received after the JSON data that server is passed over, and the JSON forms can be carried out using general FASTJSON modes
Parsing operation, parses the file name for needing to delete.For example, the file name after being parsed in above example is
myConfig.xml。
S103：Terminal performs the process to pending file and operates according to action type is processed.
Terminal parsing application file is processed after order, is performed the process to pending file and is operated.Specifically, can make
Specific process is performed with the various methods in the File classes of JDK offers to operate.Wherein, JDK is the software development of Java language
Kit, the java application being mainly used on mobile device, embedded device.JDK is the core of whole Java exploitations, it
Contain the class libraries of the running environment of Java, Java instruments and Java bases.File's classes (files classes) in by calling JDK
Various methods, it is possible to achieve the process to file is operated.For example, for deletion action, then the File classes that JDK can be used to provide
In delet method (Delete functions) deletion action performed to file process, Delete functions are one in file deletion letters
Number, its major function is to delete file from disk.
The application file processing method provided by the present invention, by server the side that application file processes order is issued
Formula, realize rubbish dynamic cleaning purpose, for example, for the configuration file of application program be updated or escalation process in, it is right
Carry out issuing delete command in the scratch file for being related to version or upgrading, so as to reduce these inactive files to terminal buffers space
Occupancy, mitigate the expense taken to disk, it is also possible to effectively avoid because the later stage causes system configuration to be lost the problems such as upgrade
Imitate so as to cause the disabled problem of software.
Except above by server issue application file process order mode it is (particularly invalid to terminal inactive file
Configuration file) outside the mode that processed, may also be combined with terminal local to inactive file (particularly invalid operating file)
Manner of cleaning up, so as to can further effective control software itself disk take.
Referring to Fig. 2, cleaning according to an embodiment of the invention is gone out and has been determined according to local using in the method for inactive file
When device delete cache file flow chart, comprise the steps：
S201：In terminal local, application file cleaning timer is set；
S202：Timer is cleared up according to application file, the application file of caching is read in timing；
S203：It is determined that the storage size shared by the application file of caching is more than preset memory space cleaning threshold；
S204：Delete the application file of caching.
Below by taking the terminal of android system as an example, it is described in further detail for aforementioned four step.
First, with regard to step S201 " arranging application file cleaning timer "
Local timer is configured：
The Special timer AlarmManager that Android can be adopted to provide, under system resting state, if
Timer expiry, Android can automatically waken up system to trigger timed task.AlarmManager has the work(for waking up CPU
Can, it is ensured that when every time needing to perform particular task CPU can normal work, register when CPU is in dormancy in other words
Alarm clock can be retained (can wake up CPU).
To set timer as example by AlarmManger in embodiment of the present invention.
The use of AlarmManager is divided into following two steps：
(1) timer AlarmManager is obtained
AlarmManager is the timing services that android system is provided, head when needing to use timing services
This service of android system offer first must be provided.Concrete acquisition methods are as follows：
AlarmManager alarmManager=
(AlarmManager)getSystemService(ALARM_SERVICE)；
Directly invoke this method of getSystemService, it becomes possible to get the reality of timer AlarmManager
Example.Wherein getSystemService is the interface dedicated for obtaining system service that android system is provided.
(2) arrange and repeat timer
There is one in AlarmManager dedicated for arranging the function setRepeating for repeating timer, this function
Major function be arrange timed task, this timed task once arrival after, system can reopen new timed task, newly
Timing it is identical with old timing.
The use of this function is as follows：
SetRepeating (int type, long startTime, long intervalTime, PendingIntent
pi)：
In the example of embodiment of the present invention, because periodically to carry out cleaning process to inactive file, it is advantageous to using
SetRepeating timers are setting timer.SetRepeating function setups be a cycle timer,
Periodically timer is able to ensure that task is performed by constantly timing.
2nd, with regard to step 202 " clearing up timer according to application file, the application file of caching is read in timing "
It is, for example possible to use the file that the JDK of Java is provided reads API, the application of caching is read by the timing of File classes
File.Specifically, the API that a set of file of the JDK offers of the Java that file is used reads is read, using File classes come to file
It is read out.The mode that File classes read file is as follows：File (file path), by the path of file the construction of File is delivered to
In function, such system will return the example file of this document.Subsequently letter can be carried out to file by document instance file
The acquisition of breath or the associative operation of file.
3rd, " judge the storage size shared by the application file for caching whether more than preset storage with regard to step 203
Space cleaning threshold "
Still by above in the way of " file that the JDK of Java is provided reads API ", read file document instance it
Afterwards, length methods therein can be called to obtain the size of file.The wherein major function of this function of length methods
It is the size information for returning current file.Thus, it is possible to which the size of current file has been got by length functions.
Need in advance to arrange a memory space cleaning threshold (file threshold value), be in order to big file is deleted, such as
The Documents Comparison of fruit caching is little, now it is considered that there is no need to delete it, because little cache file is to system disk
Expense it is smaller, affect to be negligible.If file is excessive will to produce certain have impact on to system.For example, originally
Threshold value is set to 50M in example, and in actual use the value can be configured size according to real needs, will read
Size and threshold value 50M to file carries out size contrast.
4th, with regard to step S204 " deleting the application file of caching "
Still such as above example, if file size is bigger than threshold value 50M, now deletion action is carried out to file.Delete text
The method of part be by calling file in delete functions deleting file, Delete functions are one in file
Function is deleted, its major function is to delete file from disk.If cache file is not above threshold size, now not
Any operation is done, i.e., for small documents will not carry out deletion action to it.
Corresponding with said method embodiment, the present invention also provides a kind of device processed application file.Referring to
Fig. 3, shows the apparatus structure schematic diagram that the present invention is processed application file, and the device includes：
Order receiving unit 301 is processed, the application file for receiving application server transmission processes order；
Process command resolution unit 302, for parsing the application file order processed, know pending file identification with
And process action type；
Operation execution unit 303 is processed, for according to action type is processed, performing the process to pending file and operating.
Pending file identification can be file name either file exclusive identification code or other represent files information,
Process mode of operation of the action type instruction to pending file is processed, for example, processing operation includes deletion action, updates operation
(old edition presents is replaced with new edition file), etc..
In practical operation, application server sends application file and processes opportunity of order and do not limit to terminal, for example, can be with
Periodically issue application file and process order, or application file is issued as needed in technical attendant and process order, Huo Zhe
Version updating is carried out to application or application file is issued when deleting legacy version to process order, or terminal to report certain/a bit should
Order is processed with application file is issued when file is invalid.The application file processes order includes the text that instruction terminal is processed
Part title and process action type.
In order to ensure terminal receives the application file process order that application server is issued, need to maintain terminal with application
Communication connection between server.For example, two can be maintained by way of terminal periodically sends heartbeat packet to application server
Communication connection between person.Specifically, terminal periodically to application server send heartbeat packet, heartbeat packet carried terminal IP address,
Terminal device information；Application server receives heartbeat packet, it is determined that keep communicating with terminal, so as to practical writing can be sent to terminal
Part process order.
Preferably, the device also includes：Heartbeat packet transmitting element 304, for periodically to application server send heartbeat packet,
The heartbeat packet carried terminal IP address, terminal device information.
It can be seen that, if it is desired to can implement by server lower section control life during application server and terminal communication
Order, now needs the heartbeat packet for maintaining and server.Heartbeat packet is mainly terminal periodically to server one sky of transmission
Order ensures that the connection of terminal and server will not disconnect because of time-out.Firstly, because process in terminal and server communication
In, if service end long-time does not receive the message of terminal, service end in order to discharge the resource that the terminal takes can disconnect with
The connection of terminal.If server and terminal are disconnected connection, then later terminal just cannot and server communication, if it is desired to
