Technical Field
The present invention relates to the field of application update technologies, and in particular, to an application program update method for a terminal device.
Background
In the Android system, applications all exist in the form of APK (Android Package). At present, the updating of the application program on the terminal device generally uses the traditional updating method, which includes three types. The first is a method of updating an application program by using a tengtong ticker (tengtong hot update scheme), and an update patch of a single application program integrated with a certain update function can be updated by using the tengtong hot update scheme. The second is a mode of updating an application program through an ali Sophix (ali hot update scheme), and an update patch of a single application integrated with a certain update function can be updated through the ali hot update scheme. And the third is that through a mode of updating the application program by Android's own multitex replacement, the unloaded dex file is replaced by using the Android's dex file (the dex file is a program that the Android virtual machine can run) loading mechanism to realize the application program updating.
However, the above three updating methods can only update the application program itself needing to be updated, and cannot involve the updating of other application programs associated with the application program needing to be updated. Such a situation may arise with conventional update approaches: if the application program a updates a certain function a, but the function a is also supported in other application programs, at this time, since the application program a updates the function a, partial logic in the function a is changed, and finally, other applications using the function a generate an exception when calling the function a, so that the function a cannot be normally used.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The application program updating method of the terminal equipment provided by the embodiment of the invention mainly relates to two execution main bodies: a server and a client. The server is used for searching the associated application program set of the target application program when the target application program is triggered to be updated. The client is used for carrying out updating and installation on the application programs which are left after the installed application programs are filtered and filtered in a centralized mode for the associated application programs of the target application program. The embodiment of the invention realizes the combined update of the target application program and the application program related to the target application program through the communication and the cooperation of the server and the client. The following describes an application updating method of a terminal device according to an embodiment of the present invention from different execution subject perspectives.
Service terminal
Fig. 1 is a schematic flowchart of an application update method of a terminal device according to one embodiment of the present invention. Referring to fig. 1, in an embodiment of the present invention, the method for updating an application program of a terminal device may include steps S102 to S108.
Step S102, update package information of the target application program is obtained.
Step S104, searching a related application program set of the target application program based on the update package information of the target application program to obtain a first application list consisting of the related application program set. The set of associated applications includes a target application.
And step S106, sending the first application list to the client, and receiving a second application list returned by the client after the client filters the installed application programs from the first application list.
And step S108, generating an update package according to the second application list, and sending the update package to the client to install the update package.
According to the embodiment of the invention, when the target application program of the terminal equipment needs to be updated, the update package information of the target application program is obtained, the associated application program set of the target application program is searched based on the update package of the target application program, the first application list consisting of the associated application program set is obtained, the associated application program set comprises the target application program, then the first application list is issued to the client, the second application list returned after the client filters the installed application program from the first application list is received, the update package is generated according to the second application list, and the update package is issued to the client to install the update package. Based on the scheme provided by the invention, when a certain target application program is updated, the associated application program set of the target application program can be automatically searched, so that the associated application programs related to the functions of the target application program are also updated, and the situations of abnormity, crash and the like when all application programs related to a certain function of the application program use the function are avoided when the certain application program updates the certain function. And the application programs installed on the client can be filtered out by filtering the first application list, so that repeated updating of the installed application programs on the mobile terminal is effectively avoided, and the updating efficiency is further improved.
The update package information mentioned in step S102 may be version information of the target application update. For example, may include a version number of an updated version of the application, included functionality, associated application, and/or file storage location, etc.
The update request of the target application program can be provided through a server side or a client side. In an embodiment of the present invention, when an update request for updating the target application is made through the server, the update package information of the target application, which is stored in advance, may be obtained from the server. In other embodiments of the present invention, when an update request of a target application is made through a client, update package information of the target application uploaded by the client may be received.
In some embodiments of the present invention, step S104 may further include the steps of:
step 1: and acquiring a first function set covered by the target application program according to the update package information.
A function set is a collection of all function names and corresponding function descriptions supported by an application, and may be stored in a database in advance. The first set of functions in this step may be defined as an enum enumeration type to ensure that the order of functions is incremented.
Step 2: and taking the first function set as a screening function set, searching each function in the screening function set item by item, and screening out an application program related to any function in the screening function set as a related application program set.
And step 3: and acquiring a second function set according to the screened associated application program set. Wherein the second set of functions covers the functions of each application in the set of associated applications. It is to be understood that the first set of functions corresponds to a subset of the second set of functions.
The second set of functions in this step may be defined as an enum enumeration type to ensure that the order of functions is incremented.
And 4, step 4: and circularly executing to take the second function set as a new screening function set, searching each function in the screening function set item by item, screening out a new associated application program set, acquiring the new second function set according to the new associated application program set, wherein the new second function set covers the functions of each application program in the new associated application program set until the new second function set is the same as the second function set in the previous round.
And 5: and counting the application programs in the finally obtained associated application program set, and removing repeated application programs.
Step 6: a first list of applications comprised of the set of deduplicated associated applications is generated.
In the embodiment, the target application program and all application programs related to the target application program can be screened out by searching each function in the screening function set item by item, so that a more comprehensive related application program set is obtained, and the searching efficiency of the related application program set is improved.
In some further embodiments, when searching items of functions in the screening function set one by one, and screening out an application program related to any function in the screening function set as an associated application program set, the function set of each application program may be first obtained, and then the function set of each application program is respectively subjected to and operation with the screening function set, if the function set of a certain application program and the screening function set are subjected to and the operation result is true, the application program is determined to be an application program associated with the target application program, and all application programs associated with the target application program are counted to form the associated application program set. Therefore, the application program associated with the target application program can be conveniently and quickly determined through the operation of the function set of each application program and the screening function set, so that the associated application program set is obtained, and the updating efficiency is improved.
Illustratively, assume that the first set of functions corresponding to the target application is the screening function set a. The functions covered by the screening function set a are function a, function B and function C, if the functions covered by the function set B of one application program are function a, function d and function e, and the functions covered by the function set C of another application program are function f, function g and function h. At this time, when the function set B and the function set C are respectively operated and compared with the screening function set a, it can be obtained that the operation result of the function set B and the screening function set a is true, and the operation result of the function set C and the screening function set a is false. That is, in this case, the application corresponding to the function set B is a related application that needs to be updated together with the target application and needs to be screened, and the application corresponding to the function set C is an application that does not need to be updated together with the target application and does not need to be screened.
In addition, to facilitate statistics of the applications associated with the target application, after determining that the application is the application associated with the target application, identification information may be added to the application associated with the target application (for example, a tag may be added to the application associated with the target application), and then all the applications associated with the target application are obtained according to the identification information statistics.
In some embodiments of the invention, generating the update package from the second application list may include: searching the update files of all the application programs in the second application list; and packaging the update file into an update package. By searching and packaging the update files of the application programs in the second application list, the update files can be quickly transmitted, and the update efficiency is improved.
In the data transmission process, illegal data can be transmitted due to illegal tampering, and potential safety hazards are caused. For this case, the first check code of the update package may be further generated after the update file is packaged into the update package. Specifically, the first check code may be generated according to a preset calculation manner. And then, the first check code and the update package are issued to the client together, so that the client checks the update package to determine the correctness of the update package, and the safety of data transmission is ensured. The preset calculation mode may be set according to an actual application requirement, for example, an MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm, MD5 Algorithm for short), that is, the server may generate the first check code through the MD5 Algorithm. The MD5 algorithm is a widely used cryptographic hash function that generates a 128-bit hash value to ensure the integrity of the message transmission.
In addition, after step S108, the server may also receive an update result returned by the client, so as to know the update condition of the application program in time.
Client terminal
Fig. 2 is a schematic flowchart of an application updating method of a terminal device according to another embodiment of the present invention. Referring to fig. 2, in an embodiment of the present invention, the method for updating an application program of a terminal device may include steps S202 to S206.
Step S202, when the target application program needs to be updated, a first application list issued by the server is received. The first application list is composed of a set of associated applications of the target application, the set of associated applications including the target application.
And step S204, screening and filtering the installed application programs from the first application list to obtain a second application list, and uploading the second application list to the server.
And step S206, receiving the update package generated according to the second application list and issued by the server, and installing the update package.
In the embodiment of the invention, when the target application program needs to be updated, a first application list composed of an associated application program set of the target application program and transmitted by the server is received, the installed application program is further screened and filtered from the first application list to obtain a second application list, the second application list is uploaded to the server, then an update package generated according to the second application list and transmitted by the server is received, and the received update package is installed. By adopting the embodiment of the invention, the target application program and the application program associated with a certain function of the target application program can be updated together, so that the scenes of abnormity, crash and the like of all the application programs associated with the certain function of the target application program when the function is used are avoided, and the client can filter the application programs installed on the client in the first application list, so that the repeated updating of the installed application programs on the mobile terminal can be effectively avoided, and the updating efficiency is further improved.
In some embodiments of the present invention, the step of filtering out the installed applications from the first application list to obtain a second application list further may include: acquiring an installed application list of a client; matching the version number and the function of the first application list with the installed application list, and screening and filtering application programs installed on the client side in the first application list; and forming a second application list based on the filtered first application list. Here the list of installed applications consists of a set of installed applications on the client. The set of installed applications may include historical versions of the target application and historical versions of applications associated with the target application.
When the version numbers and functions of the first application list and the installed application list are matched, specifically, one application program in the first application list may be matched with the version numbers and functions of the application programs in the installed application list. If a certain application program in the first application list is consistent with the version number and the function of the application program in the installed application list, it is indicated that the application program is an application program installed on the client, and the application program needs to be filtered from the first application list, so that a second application list is generated based on the application programs left in the filtered first application list.
The present invention provides an alternative installation for installation of update packages. For example, the class loader, the address loader and the dex loader of all the application programs related to the update package can be read first, then the dex address lists of all the application programs related to the update package are obtained through the address loader, then the dex file positions corresponding to all the application programs are determined according to the dex address lists, finally the dex files of all the application programs are loaded through the dex loader according to the dex file positions, the dex address lists are updated, and therefore the updating and installation of all the application programs in the update package can be completed.
After the client finishes the updating and installation of each application program in the updating package, the client can also return an updating result to the server, so that the server can know the updating and installation condition in time.
In consideration of the security of data transmission, the update package may also be checked before being installed to determine the correctness of the update package. Specifically, a first check code of an update package issued by a server can be received, wherein the first check code is generated by the server according to a preset calculation mode; the client calculates a second check code of the update package received by the client through the same preset calculation mode as that used by the server; comparing whether the first check code and the second check code are equal; if the first check code is equal to the second check code, the check is passed; and if the first check code and the second check code are not equal, the check is not passed. The preset calculation mode may be set according to actual application requirements, and may be, for example, an MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm, MD5 Algorithm for short). That is, the server generates the first check code through the MD5 algorithm, the client generates the second check code through the MD5 algorithm that is the same as the server, and the correctness of the update package is checked through the comparison result between the first check code and the second check code. The MD5 algorithm is a widely used cryptographic hash function that generates a 128-bit hash value to ensure the integrity of the message transmission.
Wherein, when comparing whether the second check code and the first check code are equal, it is possible to determine whether the second check code and the first check code are equal by comparing the sizes of the character strings.
In some embodiments, after updating the dex address list, a restart command may also be sent to the application program that has updated the dex address list to trigger the application program to restart, thereby completing the update. And then, returning the updating result to the server so that the server can know the updating condition in time.
In order to make the technical means of the present invention more clearly understood, a detailed description is provided below of specific embodiments of an application program updating method of a terminal device in some alternative embodiments of the present invention.
