Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a flowchart illustrating a preferred embodiment of a method for recommending download of an application program according to the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.
The recommended downloading method of the Application program is applied to one or more electronic devices, which are devices capable of automatically performing numerical calculation and/or information processing according to preset or stored instructions, and the hardware of the electronic devices includes, but is not limited to, a microprocessor, an Application Specific Integrated Circuit (ASIC), a Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.
The electronic device may be any electronic product capable of performing human-computer interaction with a user, for example, a Personal computer, a tablet computer, a smart phone, a Personal Digital Assistant (PDA), a game machine, an interactive Internet Protocol Television (IPTV), an intelligent wearable device, and the like.
The electronic device may also include a network device and/or a user device. The network device includes, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a cloud computing (cloud computing) based cloud consisting of a large number of hosts or network servers.
The Network where the electronic device is located includes, but is not limited to, the internet, a wide area Network, a metropolitan area Network, a local area Network, a Virtual Private Network (VPN), and the like.
The flow of the preferred embodiment of the method for recommending and downloading the application program by the electronic device is specifically as follows.
And S10, when the application program download address is detected, acquiring the download address as a target download address.
In at least one embodiment of the present invention, after acquiring the application program download address, the electronic device may process the application program download address, and then recommend the application program corresponding to the application program download address to other users for downloading, where a specific processing procedure will be described in detail below.
Specifically, the application program download address may be obtained from any channel, which is not limited in the present invention.
Specifically, the arbitrary channels may include, but are not limited to: any application download website, any application download platform, etc.
And S11, converting the target download address into a target two-dimensional code.
In at least one embodiment of the present invention, the electronic device converting the target download address into a target two-dimensional code includes:
the electronic equipment analyzes the target download address to obtain an encoding mode, further, the electronic equipment encodes the target download address in the encoding mode to obtain a data code, generates an error correcting code according to the data code, integrates the data code and the error correcting code to generate a target code, and inputs the target code into a matrix to obtain the target two-dimensional code.
Among them, the two-dimensional code is a special type of barcode created by Denso Wave Incorporated. Two-dimensional codes encode text and numbers using a pattern of pixels that is easily read by an optical scanner. The dimension code is a special type of bar code and can encode information such as numbers, letters, Japanese characters and the like.
Specifically, the step of converting the target download address into the target two-dimensional code by the electronic device mainly includes the following steps:
(1) and (6) analyzing the data.
The two-dimensional code encodes a string of text. The two-dimensional code standard has four coding modes: numbers, characters, bytes, and japanese. Each encoding mode encodes text as a string of binary digits (1 and 0), but each mode converts text to binary digits using a different method, and each encoding mode encodes data using the shortest possible string of binary digits. The first step should therefore be to perform a data analysis to determine if the target download address can conform to the encoding of a number, letter, byte or japanese pattern and then select the optimized encoding pattern.
(2) And (6) encoding data.
After a proper coding mode is selected for the target download address, the next step is to code the target download address and generate a plurality of groups of 8-bit-length data codes.
(3) An error correction code (Reed-Solomon error correction) is generated.
And after generating the data code corresponding to the target download address, the electronic equipment further generates the error correction code according to the data code. The data code and the error correction code may be read using any two-dimensional code scanner. By comparing the two codewords, the two-dimensional code scanner can determine whether data is correctly read, and if data is not correctly read, errors of the data code can be corrected using the error correction code.
(4) And (5) finally coding.
The electronic device arranges the data code and the error correction code in a certain order.
Specifically, for a large-sized two-dimensional code, the data code and the error correction code must be arranged in blocks, and the blocks must be staggered according to the specification of the two-dimensional code.
(5) The modules are placed in a matrix.
After arranging the data code and the error correction code, these binary digits are placed in a specific way in a two-dimensional code matrix.
(6) A mask pattern.
Two-dimensional code scanners sometimes have difficulty in correctly reading a particular pattern of code words. For this case, eight mask patterns are defined in the two-dimensional code specification, and each specific pattern may change the original two-dimensional code pattern.
(7) Format and version information.
Format and (if necessary) version information are added to the blank specific area in the two-dimensional code matrix. The format information defines an error correction level and a pattern of the mask pattern. The version information defines the size of the two-dimensional code matrix.
Through the implementation mode, the target download address can be automatically converted into the target two-dimensional code for subsequent use.
And S12, packaging the target two-dimensional code to generate an executable target installation package.
In at least one embodiment of the present invention, the packaging, by the electronic device, the target two-dimensional code, and the generating the executable target installation package includes:
and the electronic equipment stores the target two-dimensional code into a source code resource file to obtain a resource file, and further packages the resource file to generate the executable target installation package.
Wherein the packaging the resource file by the electronic device, and the generating the executable target installation package comprises:
the electronic equipment packages the resource files to generate R.java files and acquires AIDL files from the resource files, processes the AIDL files to generate corresponding java files, compiles the java files to generate corresponding class files, converts the class files into dex files supported by a Davik VM, further packages the dex files and generates the target installation package.
Specifically, package compilation of applications is a specific engineering problem, so the present invention first introduces the related package compilation tools as shown in table 1:
TABLE 1
Further, the flow of packaging the target two-dimensional code by the electronic device is as follows:
1) and the electronic equipment packs the resource file to generate an R.java file.
Compiling the R.java class needs to use an aapt tool provided by the android SDK, and the concrete process of compiling the R.java file by the apt is as follows: and entering an application program directory to create a gen directory, wherein because no gen directory exists, the command has an error that a file cannot be found, and after the command is successfully executed, a directory tree and an R.java file with a package structure are generated under the gen directory.
2) And the electronic equipment processes the AIDL file and generates a corresponding java file.
The electronic equipment adopts an aidl tool carried by the android SDK to generate a java file from the aidl file. And (5) operating an aidl tool to convert the aidl file into a java file.
3) And the electronic equipment compiles the java file to generate a corresponding class file.
The electronic equipment compiles the original java file to generate a class file, and the specific command is as follows:
javac-encoding utf-8-target 1.5-bootclasspathE:\Androiddev\android-sdk-windows2.2\platforms\android-3\android.jar-d binsrc\com\byread\reader\*.java gen\com\byread\reader\R.java
the commands specify a program encoding mode, a source file position and a starting position of the adroid boot.
4) The electronic device converts the class file into a dex file supported by the Davik VM.
The electronic equipment compiles class files under the engineering bin directory into classes.
5) And the electronic equipment packs the dex file to generate the target installation package.
Through the implementation mode, the electronic equipment can automatically generate the available target installation package for storage and reservation.
In at least one embodiment of the invention, the method further comprises:
the electronic equipment signs the target installation package by using a jar scanner command, generates a signed packaging program, and aligns the packaging program.
Specifically, the electronic device first packages and generates an unsigned apk file, i.e., the target installation package. Specifically, the electronic device packages the packaged resource file, the packaged class file dex file and the libs file by using an apkbuilder tool to generate an unsigned apk file, and then signs the unsigned apk file by using a jarsinger tool to generate a signed packaging program, and the electronic device processes the signed packaging program, otherwise, the electronic device cannot release the signed packaging program.
With the above embodiment, the target installation package can be released, so that the target installation package can be used in a wide range.
And S13, saving the target installation package.
In at least one embodiment of the invention, the electronic device may save the target installation package locally to facilitate invocation.
Of course, in other embodiments, the electronic device may also store the target installation package in another server or database, which is not limited by the present invention.
S14, configuring a trigger event for the target installation package.
Specifically, the trigger event is used to trigger the recommended download of the target installation package.
In at least one embodiment of the present invention, the electronic device configuring the trigger event to the target installation package includes:
the electronic equipment determines an event to be modified, and configures the event to be modified as the trigger event based on an event interception/distribution mechanism of the event to be modified.
Wherein, the event to be modified may be a touch event or the like.
It can be understood that the graphical user interface structure of the Android is a tree structure, the top layer (root node) of the tree is a View group contained in Activity, a plurality of View group nodes are arranged below the tree, a plurality of View group nodes or View nodes are arranged below each node, and so on. The delivery and handling of Touch events is closely related to this structure. A full touch event consists of one ACTION _ DOWN, zero or one or more ACTION _ MOVEs, and one ACTION _ UP.
For example: the electronic device may configure the touch event as the trigger event in the following manner.
(1) Event distribution: public boilean dispatctchTouchent (motionEvent ev)
When a Touch event occurs, the dispatch Touch () method of Activity will transmit the event to the dispatch Touch () of the outermost View in a tunnel mode (i.e., sequentially passing from the root node down to the innermost child node or stopping transmission due to a certain condition in a certain node in the middle), and distribute the event by the dispatch Touch () of the View.
The event distribution logic for the dispatchTouchent is as follows:
return true: events are distributed to the current View and consumed by the DispatcTouchEvent () method, while events stop passing down.
return false: returning the event to the ontouchvent () of the previous level (maybe Activity, also maybe parent View) of the current View for consumption.
Dispatch touch (ev): events are automatically distributed to the onInterceptTouchent method of the current View. It should be noted that the premise of the View response dispatctchtouchvent and onInterceptttouchvent is that a child View can be added to the View, that is, the View has child nodes to distribute and intercept.
(2) Event interception: public borolan onInterceptTouchent (MotionEvent ev)
When the dispatch touch () method of the outer View returns a super.
The event interception logic of onInterceptTouchent is as follows:
return true: and intercepting the event, and handing the intercepted event to ontouchvent () of the current View for processing.
return false: and releasing the event, transmitting the event on the current View to the child View, and continuously distributing the event by the dispatch TouchEvent () of the child View.
Turn super. onInterceptTouchavent (ev): the event is intercepted by default, and the intercepted event is handed over to the ontouchvent () of the current View for processing.
(3) And (3) event response: public boilean on Touchent (MotionEvent ev)
The condition under which ontouchempty () is called can be known by (1) and (2).
The event response logic for onTouchEvent is as follows:
return false: events are passed up from the current View and are all received by the onTouchEvent () of the top View, and if the onTouchEvent () passed to the top returns false, the event "disappears" and the next event is not received.
return true: the event is received and consumed.
Turn super. The logic for the default handling event is the same as the return false.
Further, the method further comprises:
when the trigger event is detected, the electronic equipment displays the target two-dimensional code for scanning.
Specifically, the electronic device sets an OnTouchListener listener, and then the OnTouchListener method is executed first in the execution process, and then whether the ontouchvent method needs to be executed is determined according to the return value. Whether ontouchevevent needs to be called is related to the value of result: if result is true, no call is made; otherwise, it is called. The onTouchEvent function is modified so that when the touch event is triggered, an application two-dimensional code picture is displayed.
Through the implementation mode, when the trigger event is detected to be triggered, the target two-dimensional code can be directly displayed for scanning and downloading by a user, so that the application program is quickly recommended and downloaded, the time for the user to inquire is saved, and the method is more friendly and convenient.
In summary, according to the present invention, when an application program download address is detected, the download address is obtained as a target download address, the target download address is converted into a target two-dimensional code, the target two-dimensional code is further packaged to generate an executable target installation package, the target installation package is stored, and a trigger event for the target installation package is configured, so that recommendation download for the application program is realized, a user searches for the target installation package manually in an unordered manner, and download efficiency is improved.

In at least one embodiment of the invention, the method further comprises:
the signing unit 115 signs the target installation package by using a jarsegner command to generate a signed packaging program, and the aligning unit 116 aligns the packaging program.
Specifically, the packaging unit 112 first packages and generates an unsigned apk file, i.e., the target installation package. Specifically, the packing unit 112 packs the packed resource file, the packed class file dex file, and the libs file by using an apkbuilder tool to generate an unsigned apk file, the signing unit 115 signs the unsigned apk file by using a jarsinger tool to generate a signed packing program, and the aligning unit 116 processes the signed packing program, otherwise, the signed packing program cannot be issued.

Of course, in other embodiments, the saving unit 113 may also save the target installation package in other servers or databases, and the present invention is not limited thereto.
The configuration unit 114 configures a trigger event for the target installation package.
Specifically, the trigger event is used to trigger the recommended download of the target installation package.
In at least one embodiment of the present invention, the configuring unit 114 configures the trigger event for the target installation package, including:
the configuration unit 114 determines an event to be modified, and configures the event to be modified as the trigger event based on an event interception/distribution mechanism of the event to be modified.
Wherein, the event to be modified may be a touch event or the like.
It can be understood that the graphical user interface structure of the Android is a tree structure, the top layer (root node) of the tree is a View group contained in Activity, a plurality of View group nodes are arranged below the tree, a plurality of View group nodes or View nodes are arranged below each node, and so on. The delivery and handling of Touch events is closely related to this structure. A full touch event consists of one ACTION _ DOWN, zero or one or more ACTION _ MOVEs, and one ACTION _ UP.
For example: the configuration unit 114 may configure the touch event as the trigger event in the following manner.
(1) Event distribution: public boilean dispatctchTouchent (motionEvent ev)
When a Touch event occurs, the dispatch Touch () method of Activity will transmit the event to the dispatch Touch () of the outermost View in a tunnel mode (i.e., sequentially passing from the root node down to the innermost child node or stopping transmission due to a certain condition in a certain node in the middle), and distribute the event by the dispatch Touch () of the View.
The event distribution logic for the dispatchTouchent is as follows:
return true: events are distributed to the current View and consumed by the DispatcTouchEvent () method, while events stop passing down.
return false: returning the event to the ontouchvent () of the previous level (maybe Activity, also maybe parent View) of the current View for consumption.
Dispatch touch (ev): events are automatically distributed to the onInterceptTouchent method of the current View. It should be noted that the premise of the View response dispatctchtouchvent and onInterceptttouchvent is that a child View can be added to the View, that is, the View has child nodes to distribute and intercept.
(2) Event interception: public borolan onInterceptTouchent (MotionEvent ev)
When the dispatch touch () method of the outer View returns a super.
The event interception logic of onInterceptTouchent is as follows:
return true: and intercepting the event, and handing the intercepted event to ontouchvent () of the current View for processing.
return false: and releasing the event, transmitting the event on the current View to the child View, and continuously distributing the event by the dispatch TouchEvent () of the child View.
Turn super. onInterceptTouchavent (ev): the event is intercepted by default, and the intercepted event is handed over to the ontouchvent () of the current View for processing.
(3) And (3) event response: public boilean on Touchent (MotionEvent ev)
The condition under which ontouchempty () is called can be known by (1) and (2).
The event response logic for onTouchEvent is as follows:
return false: events are passed up from the current View and are all received by the onTouchEvent () of the top View, and if the onTouchEvent () passed to the top returns false, the event "disappears" and the next event is not received.
return true: the event is received and consumed.
Turn super. The logic for the default handling event is the same as the return false.
Further, the method further comprises:
when the trigger event is detected, the display unit 117 displays the target two-dimensional code for scanning.
Specifically, the display unit 117 sets an OnTouchListener monitor, and then the OnTouchListener method is executed first during the execution process, and then it is determined whether the ontouchvent method needs to be executed according to the return value. Whether ontouchevevent needs to be called is related to the value of result: if result is true, no call is made; otherwise, it is called. The onTouchEvent function is modified so that when the touch event is triggered, an application two-dimensional code picture is displayed.
Through the implementation mode, when the trigger event is detected to be triggered, the target two-dimensional code can be directly displayed for scanning and downloading by a user, so that the application program is quickly recommended and downloaded, the time for the user to inquire is saved, and the method is more friendly and convenient.
In summary, according to the present invention, when an application program download address is detected, the download address is obtained as a target download address, the target download address is converted into a target two-dimensional code, the target two-dimensional code is further packaged to generate an executable target installation package, the target installation package is stored, and a trigger event for the target installation package is configured, so that recommendation download for the application program is realized, a user searches for the target installation package manually in an unordered manner, and download efficiency is improved.
