[0043] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0044] The application installation method provided by the embodiment of the present disclosure is applied to the scenario where a terminal installs an application based on a user instruction.

[0045] When the terminal installs an application, it is necessary to verify the installation package file of the application before the installation of the application can be completed. In the related art, when the terminal verifies the application installation package, the terminal needs to perform compilation optimization actions on the application through the compilation optimization tool (dex2oat). By disassembling the time-consuming information of each stage of the compilation process, it can be found that during the application installation process, it is necessary to verify the rationality of the application method. That is, for all executable (Dex) files contained in the installation package file of the application, each method is accessed by traversing layer by layer, and each instruction contained in the method is verified for rationality. As the functions of terminal applications become more and more abundant, the amount of code of the application is also increasing, the executable files in the installation package file increase synchronously, and the methods that need to be accessed and verified also increase and decrease accordingly, resulting in the verification process of the application taking longer and longer, and then the application installation time is also longer and longer, which seriously affects the user experience. In addition, due to the increase in the time-consuming installation of the application, the consumption of the terminal processor during the installation of the application will also increase, which will lead to an increase in the power consumption of the installed application.

[0046] In view of this, the present disclosure proposes an application installation method, which completes the verification process of the application installation package file in the cloud in advance, and obtains a verification file containing the verification result of the application installation package file. When the terminal requests to download and install the application, the installation package file and the verification file of the application to be installed are obtained. When the terminal verifies the installation package file during the installation process, the verification result can be quickly obtained through the obtained verification file, thereby shortening the time spent on verifying the application on the terminal, and ultimately shortening the time spent on application installation, reducing the consumption of the terminal processor, and reducing the power consumption of application installation.

[0047] Figure 1 FIG. 1 is a flow chart of an application installation method according to an exemplary embodiment. Figure 1 As shown, the method includes step S101 to step S102.

[0048] In step S101, in response to an application installation instruction, a request for obtaining an installation package file of a target application is sent to the cloud, and the installation file sent by the cloud based on the request is obtained.

[0049] The installation file includes the installation package file and verification file of the target application.

[0050] In step S102, during the installation process of the installation package file, the installation package file is verified by using a verification file to complete the installation of the target application.

[0051] In the disclosed embodiment, the user selects the target application to be downloaded in the application store of the terminal, and issues an instruction to download the application (such as clicking "Install" under the icon of the target application in the display interface of the application store). After receiving the instruction, the terminal application store sends a request to the cloud to obtain the installation package of the target application, and receives the installation file including the verification file and the installation package file issued by the cloud.

[0052] In the disclosed embodiment, when installing an application, the installation package file is verified using the downloaded verification file, without the need for the terminal processor to call a compilation optimization tool (such as dex2oat) for verification, thereby shortening the time spent on verifying the application on the terminal, ultimately shortening the time spent on application installation, reducing the consumption of the terminal processor, and reducing the power consumption of application installation.

[0053] In the embodiment of the present disclosure, verifying the installation package file by verifying the file includes verifying the entire file before installing the installation package file, and verifying the installed sub-files during the installation of the installation package file. The following embodiment of the present disclosure describes the method for verifying the installation package file.

[0054] Figure 2 FIG. 1 is a flow chart showing a method for verifying an installation package file by verifying a file according to an exemplary embodiment. Figure 2 As shown, the method includes step S201 to step S202.

[0055] In step S201, a first verification is performed on the installation package file by using a verification file.

[0056] In step S202, according to the verification result of the first verification, the installation process of the installation package file is entered, and a second verification is performed on the multiple sub-files included in the installation package file during the installation process.

[0057] In the disclosed embodiment, when the terminal obtains the installation package file from the cloud, due to cloud problems (such as the developer uploads a new version of the installation package, but the verification text is not updated accordingly) or errors in the download of the installation package file, the downloaded verification file may not be applicable to the downloaded installation package file. Therefore, the entire file should be verified before the installation package file is installed to determine whether the downloaded verification file is applicable to the downloaded installation package file, and then decide whether to use the verification file to verify the installed file during the application installation process.

[0058] In the disclosed embodiment, the first verification is performed on the entire installation package file before installation, and different verification strategies are adopted for multiple sub-files included in the installation package file during the installation process based on the verification results. It is ensured that the verification results of the multiple sub-files included in the installation package file during the installation process are consistent with the actual situation of the installation package file, and it is ensured that the target application can run normally after installation.

[0059] In the embodiment of the present disclosure, the purpose of performing the first check on the installation package file is to determine whether the check file is applicable to the installation package file (whether the version and package name match). The following embodiment of the present disclosure describes the method for performing the first check.

[0060] Figure 3 FIG. 1 is a flowchart of a method for performing a first verification on an installation package file by using a verification file according to another exemplary embodiment. Figure 3 As shown, the method includes step S301 to step S302.

[0061] In step S301, a first verification file among verification files is extracted.

[0062] In step S302, the version information and package name information of the installation package file are verified using the first verification file.

[0063] The first verification file includes version information and package name information of the target application.

[0064] It is understandable that there are differences in the installation package files of different applications, and there will be differences in the verification process and verification results of the installation package files of different applications. There will also be differences in the installation packages of different versions of the same application, and there will also be differences in the verification process and verification results of the installation package files of different versions of the same application. Therefore, the verification file in the present disclosure is targeted and is only for the installation package files of the feature version of a specific application. The present disclosure verifies the version information and package name information of the installation package file to ensure that the downloaded verification file is a verification file suitable for the downloaded installation package file. The accuracy of the verification result is guaranteed to ensure that the target application can run normally after installation.

[0065] In the embodiments of the present disclosure, different verification strategies are adopted for multiple sub-files included in the installation package file during the installation process according to the verification result of the first verification of the entire file before the installation package file is installed. The following embodiments of the present disclosure further illustrate the method of performing the second verification on multiple sub-files included in the installation package file during the installation process.

[0066] Figure 4 FIG. 1 is a flow chart showing a method for performing a second check on multiple sub-files included in an installation package file during an installation process according to an exemplary embodiment. Figure 4As shown, the method includes step S401, step S402A and step S402B.

[0067] In step S401, a first verification is performed on the installation package file by using a verification file.

[0068] In step S402A, in response to the installation package file passing the first verification, a second verification is performed on multiple sub-files of the installation package file in the installation process according to the verification file.

[0069] In step S402B, in response to the installation package file failing the first verification, the terminal accesses multiple sub-files included in the installation package file one by one during the installation process and performs a second verification.

[0070] In the disclosed embodiment, the installation package file passes the first verification, indicating that the downloaded verification file is applicable to the downloaded installation package file. Based on the verification file, multiple sub-files of the installation package file can be verified during the installation of the installation package file, and the verification result can be directly obtained from the verification file to achieve fast verification. The time spent on verifying the application on the terminal is shortened, and the time spent on application installation is ultimately shortened, and the consumption of the terminal processor is reduced, thereby reducing the power consumption of application installation.

[0071] In the disclosed embodiment, if the installation package file fails the first verification, it indicates that the downloaded verification file is not applicable to the downloaded installation package file. In the installation process of the installation package file, the multiple sub-files of the installation package file are verified in a traditional manner, and the processor of the terminal parses the sub-files to obtain the verification result, thereby ensuring that the verification of the installation package file can be completed even if the downloaded verification file is invalid, so that the target application can be installed and run normally.

[0072] In the embodiment of the present disclosure, the verification file includes a second verification file, which is the verification result of the target application function information. When the downloaded verification file is applicable to the downloaded installation package file, it can be directly used as the verification result for the installed sub-files during the installation process. The following embodiment of the present disclosure further describes the method of performing a second verification on multiple sub-files included in the installation package file during the installation process.

[0073] Figure 5 FIG. 1 is a flow chart showing a method for performing a second check on multiple sub-files included in an installation package file during an installation process according to an exemplary embodiment. Figure 5 As shown, the method includes step S501 to step S502.

[0074] In step S501, in response to the version information of the installation package file matching the version information included in the first verification file, the package name information of the installation package file matches the package name information included in the first verification file.

[0075] In step S502, a second verification file is extracted from the verification file in the installation process, the verification result of the target application function information is obtained, and a second verification of multiple sub-files included in the installation package file is completed.

[0076] In the disclosed embodiment, if the terminal detects that the package name information and version information of the application recorded in the manifest file (first verification file) in the verification file matches the current application installation package information, the descriptor (fd) of the verification file is used as the installation input parameter during the installation of the installation package file and is passed to the compilation and installation process of the installation package. When the descriptor is used to trigger the compilation of the application, the decompiled file (second verification file) containing the verification result information can be decompressed and extracted from the verification file, and the verification result information can be read, so as to use it to implement fast verification (Fast Verify) of the application and improve the application installation speed.

[0077] The following embodiments of the present disclosure further illustrate a method for performing a second verification on a plurality of sub-files included in an installation package file during an installation process.

[0078] Figure 6 FIG. 1 is a flowchart showing a method for performing a second verification by accessing multiple sub-files contained in an installation package file one by one by a terminal in an installation process according to an exemplary embodiment. Figure 6 As shown, the method includes step S601 to step S602.

[0079] In step S601, in response to the version information of the installation package file not matching the version information included in the first verification file, and / or the package name information of the installation package file not matching the package name information included in the first verification file.

[0080] In step S602, during the installation process of the installation package file, the terminal accesses the multiple sub-files contained in the installation package file one by one, obtains the functional information of the target application, and completes the verification of the functional information, obtains the verification result of the target application functional information, and completes the second verification of the multiple sub-files contained in the installation package file.

[0081] In the disclosed embodiment, if the terminal detects that any one of the package name information and version information of the application recorded in the manifest file (first verification file) in the verification file does not match the current application installation package information. Then the decompiled file (second verification file) containing the verification result information in the representation verification file is not applicable to the installation process of this installation package file. At this time, the terminal processor (CPU) uses a general method to complete the verification during the compilation and installation of the installation package file: that is, for all executable (Dex) files contained in the installation package file of the application, each method therein is accessed by traversing layer by layer, and each instruction contained in the method is checked for rationality to obtain the verification result, ensuring that the verification of the installation package file can be completed even if the downloaded verification file is invalid, so that the target application can be installed and run normally.

[0082] In the disclosed embodiment, the cloud completes the verification process of the application installation package file in advance and obtains a verification file containing the verification result of the application installation package file. When the terminal requests to download and install the application, the cloud sends the installation package file and the verification file of the application to be installed to the terminal. The disclosed embodiment describes the application installation method applied to the cloud.

[0083] Figure 7 FIG. 1 is a flow chart of an application installation method according to an exemplary embodiment. Figure 7 As shown, the method includes step S701 to step S702.

[0084] In step S701, in response to receiving a request from a terminal for obtaining an installation package file of a target application.

[0085] In step S702, the installation file is sent to the terminal.

[0086] The installation file includes an installation package file and a verification file of the target application, the verification file includes a second verification file, and the second verification file is a verification result of the target application function information.

[0087] In the disclosed embodiment, after the cloud receives a request from the terminal to obtain the target application installation package, it sends the installation package file to the cloud and also sends a verification file corresponding to the installation package file to the terminal. The verification file includes a second verification file, which is the verification result of the target application function information, so that the terminal can quickly complete the verification and installation based on the verification file.

[0088] In the embodiment of the present disclosure, after the application developer completes the development of the application, he uploads the application installation package file to a platform that supports downloading (i.e., the cloud), and the cloud obtains the corresponding verification file based on the installation package file uploaded by the developer. The following embodiment of the present disclosure describes the installation file generation method.

[0089] Figure 8 FIG. 1 is a flow chart of a method for generating an installation file according to an exemplary embodiment. Figure 8 As shown, the method includes step S801 to step S802.

[0090] In step S801, the installation package file of the target application is received, the installation package file is parsed and compiled, and a verification file is obtained.

[0091] In step S802, the installation package file and the verification file are determined as installation files.

[0092] In the disclosed embodiment, after an application developer wants to upload an installation package file of an application to the cloud, the cloud uses compilation optimization tools and parsing tools to compile, install and parse the application installation package file uploaded by the application developer, obtains the verification file corresponding to the installation package file, and associates the installation package file and verification file of the same application as the installation file of the application, so that when the cloud receives a request from the terminal to obtain the installation package file, it can synchronously send the installation package file and verification file of the same application to the terminal.

[0093] In the embodiment of the present disclosure, when obtaining the verification file, it is necessary to obtain a first verification file for determining whether the verification file is applicable to the installation package file, and obtain a second verification file representing the verification result of the functional information of the installation package file. The following embodiment of the present disclosure describes the method for obtaining the verification file.

[0094] Fig. 9 FIG. 1 is a flow chart showing a method for obtaining a verification file according to an exemplary embodiment. Fig. 9 As shown, the method includes steps S901 to S903.

[0095] In step S901, the installation package file is parsed to obtain a first verification file including version information and package name information of the target application.

[0096] In step S902, the installation package file is compiled, the verification result of the function information of the target application is obtained, and the verification result is determined as the second verification file.

[0097] In step S903, the first verification file and the second verification file are packaged and compressed into a verification file.

[0098] In the disclosed embodiment, a compilation optimization tool is called to compile and install the application installation package file uploaded by the application developer, and a second verification file containing only verification result information is generated by controlling the compilation parameters. The installation package file is parsed using a parsing tool to obtain the version information and package name information of the application, which are written into the first verification piece in a specific format, and the second verification file containing the verification result information and the first verification file containing the version information and package name information are packaged to generate a verification file. The terminal quickly obtains the verification result through the obtained verification file, thereby shortening the time spent on verifying the application on the terminal, and ultimately shortening the time spent on application installation, reducing the consumption of the terminal processor, and reducing the power consumption of application installation.

[0099] In the disclosed embodiment, when obtaining the verification file, a first verification file is obtained for determining whether the verification file is applicable to the installation package file, and the second verification file is effective when it is applicable to the installation package file, so as to ensure that the verification result during the installation of the installation file is accurate, so that the target application can be installed and run normally. A second verification file representing the verification result of the functional information of the installation package file is obtained.

[0100] In an exemplary embodiment of the present disclosure, Fig.10 The statistical diagram of the installation speed of applications installed on different terminals is shown in the figure. Among them, terminal 3 is a terminal using the application installation method disclosed in the present invention, terminal 1 and terminal 2 are terminals using a general application installation method, and terminal 1, terminal 2 and terminal 3 use the same processor. The time taken by terminal 1 to install application A, application B, application C, application D and application E are 16025ms, 14835ms, 9075ms, 8445ms and 6470ms respectively; the time taken by terminal 2 to install application A, application B, application C, application D and application E are 12880ms, 12570ms, 6030ms, 5585ms and 4440ms respectively; the time taken by terminal 3 to install application A, application B, application C, application D and application E are 5307ms, 4781ms, 3362ms, 2701ms and 2267ms respectively. As Fig.10 As shown, the application installation speed of the terminal 3 using the application installation method of the present disclosure is significantly higher than that of the terminals 1 and 2 using the general application installation method.

[0101] In an exemplary embodiment of the present disclosure, Fig.11The energy consumption statistics of installed applications before and after the same terminal is optimized are shown in the figure. Before the terminal is optimized, the general application installation method is used, and after the terminal is optimized, the application installation method proposed in the present disclosure is used. Before the terminal is optimized, the energy consumption of application A, application B, application C, application D and application E are 5.06mAh, 4.36mAh, 2.33mAh, 2.13mAh and 1.64mAh respectively; after the terminal is optimized, the energy consumption of application A, application B, application C, application D and application E are 2.24mAh, 2.40mAh, 1.52mAh, 1.12mAh and 0.95mAh respectively. Fig.10 As shown, the installation energy consumption of the same terminal after optimization using the application installation method disclosed in the present invention is significantly lower than the installation energy consumption of the same terminal before optimization using the general application installation method.

[0102] In an exemplary embodiment of the present disclosure, Fig.12 As shown in the block diagram of the application installation method, the cloud generates the verification file corresponding to the installation package file in the following manner, and sends the installation package file and the verification file to the terminal upon receiving the download request from the terminal:

[0103] 1. After the application developer uploads the application installation package file (application.apk), call the compilation optimization tool (dex2oat) to compile and install the application installation package file uploaded by the application developer, and generate a decompiled file (primary.vdex) that does not contain the original executable (dex) file but only contains the verification result information (VerifierDeps) by controlling the compilation parameters.

[0104] 2. Use the parsing tool (aapt) to parse the installation package file to obtain the application's version information (versionCode) and package name information (packageName), and write them into the manifest file (manifest.json) in json format; package the decompiled file containing the verification result information and the manifest file containing the version information and package name information to generate a verification file (application.dm).

[0105] 3. When the user tries to download and install the application, upon receiving a request to download the application, the application installation package file and the corresponding verification file are sent to the end user's mobile phone together.

[0106] In an exemplary embodiment of the present disclosure, Fig.12 As shown in the block diagram of the application installation method, the terminal uses the following method to request the cloud to obtain the installation package file, and completes the verification and installation of the installation package file after obtaining the installation package file:

[0107] 1. The user issues an instruction to download and install the target application in the terminal's application store. The application store application on the terminal sends a request to the cloud to obtain the application installation package file, and receives and downloads the installation package file and the corresponding verification file sent by the cloud. By calling the software framework's interface (openWrite), the installation package file and the verification file are all written to the file stream (session) and submitted to the framework for installation.

[0108] 2. When processing the application installation request, the framework package installation management service will first extract the manifest file containing the package name and version information from the verification file (base.dm, i.e. application.dm, only the file name is modified). The package name and version information of the application recorded in the manifest file will be read to determine whether it matches the current application installation package information (including package name and version information). If it does not match, the downloaded verification file will be abandoned, and the terminal processor will parse the installation package file to complete the verification of the installation package file.

[0109] 3. If the package name and version information of the application recorded in the manifest file matches the current application installation package information, the descriptor (fd) of the verification file is passed to the compilation and installation process of the installation package as the installation input parameter; thereby triggering the compilation of the application to decompress and extract the decompiled file containing the verification result information from the verification file, and read the verification result information, so as to use it to implement fast verification (Fast Verify) of the application and improve the application installation speed.

[0110] In the disclosed embodiment, after the application developer uploads the installation package file of the application to the cloud, the cloud completes the verification process of the application installation package file, and obtains the verification file containing the verification result of the application installation package file. When the terminal requests to download and install the application, the installation package file and the verification file of the application to be installed are obtained synchronously. When the terminal verifies the installation package file during the installation process, the verification result is quickly obtained through the obtained verification file, thereby shortening the time spent on verifying the application on the terminal, and ultimately shortening the time spent on application installation, reducing the consumption of the terminal processor, and reducing the power consumption of application installation.

[0111] Based on the same concept, the embodiment of the present disclosure also provides an application installation device 100 and an application installation device 200 .
