Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. On the contrary, the embodiments of the invention include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
The embodiments of the invention mainly aim at the problems that when an application installation package is too large, the flow consumed in the downloading process is high, the downloading process is slow, the efficiency is low, and a user is unwilling to download, and the application utilization rate is reduced.
The following describes a method, an apparatus and an electronic device for reducing an application installation package according to an embodiment of the present invention with reference to the drawings.
FIG. 1 is a flow diagram of a method of reducing application installation packages, in accordance with one embodiment of the present invention.
As shown in fig. 1, the method for reducing the application installation package includes:
Specifically, the method for reducing the application installation package provided by the embodiment of the present invention may be executed by the apparatus for reducing the application installation package provided by the embodiment of the present invention.
The project file corresponding to the application is a file formed in the application Development process, and specifically may be a file formed by developing the application in an Integrated Development Environment (IDE).
Specifically, since the project file corresponding to the application is written by using a high-level language program and is not a machine language that can be recognized by a computer or other electronic devices, in this embodiment, after the project file corresponding to the application is obtained, the project file is first packaged and compiled to obtain a compiled file in a binary code form corresponding to the project file, so that when the application is installed, the installation device can install the application according to the binary code.
And 102, storing the first binary code corresponding to the layout file in the compiled file according to a preset storage path.
The layout file may include a View (View) file such as a menu and a picture.
The storage path can be set as required. Specifically, the location may be a certain location in the remote server, or may be a certain location in a Secure Digital Memory Card (SD Card for short) built in the network server, which is not limited herein.
In a specific implementation, a storage path may be preset, and since the item file corresponding to the application is already packaged and compiled in step 101, a compiled file in a binary code form is generated, and then after the storage path is set, the first binary code corresponding to each layout file in the compiled file may be stored in the preset storage path through commands such as adb.
And 103, replacing the first binary code corresponding to the layout file with the binary code of the storage path in the compiled file.
Specifically, after the first binary codes corresponding to each layout file in the compiled file are stored in the preset storage path, the binary codes of the storage path can be used for replacing and applying the first binary codes corresponding to each layout file in the corresponding compiled file.
In specific implementation, as for a compiled file, the first binary code belongs to a hidden file, and therefore when being loaded, the first binary code can be loaded into the stored first binary code only by calling the addasspath method in the AssetManager through reflection, and as the addasspath is a hidden api, we cannot directly call the addasspath, so that only through reflection is possible. In this embodiment of the present application, before replacing the first binary code corresponding to the layout file with the binary code of the storage path, the method may further include: the path head is determined by reflection.
Correspondingly, replacing the first binary code corresponding to the layout file with the binary code of the storage path may specifically include:
and replacing the first binary code corresponding to the layout file by the binary code of the path head and the binary code of the storage path.
It is understood that in Java, attributes, methods, construction methods, and the like of Java objects may be accessed through a reflection mechanism, and in this embodiment, a path header of the storage path may be obtained through the reflection mechanism. After the path header is obtained, the path header can be added to the storage path to replace the first binary code corresponding to the layout file in the compilation file by using the binary code of the path header and the binary code of the storage path.
In specific implementation, in order to reduce resources occupied by the binary code of the path header and the binary code of the storage path, a text file (cookie) can be generated according to the path header and the storage path, and then the binary code of the text file is used for replacing the first binary code corresponding to the layout file.
And 104, acquiring a first R file included in the compiled file.
And 105, creating a second R file in the compiled file according to the first R file to generate an installation package file corresponding to the application.
And the name of the second R file is different from that of the first R file, and the content in the second R file is the same as that in the first R file.
The R file is a file automatically generated by the system in the process of packaging and compiling the project file, and includes identifiers (IDs for short) of all the layout files, and the application can acquire the corresponding resources according to the IDs in the first R file in the installation process.
In a specific implementation, a class file with a name different from that of the first R file may be created in the compilation file, then the content in the first R file may be copied and pasted into the newly created class file to obtain a second R file, so as to generate an installation package file corresponding to the application, that is, step 105 may specifically include:
creating a class file in the compiled file;
and copying the content in the first R file into the class file to generate a second R file.
Specifically, the layout file in the compiled file is already stored in the preset storage path, so that the first R file cannot be executed, and the corresponding layout file is obtained.
According to the method for reducing the application installation package, provided by the embodiment of the invention, firstly, the project files corresponding to the application are packaged and compiled to generate the compiled files corresponding to the application; then storing the first binary code corresponding to the layout file in the compiled file according to a preset storage path; replacing the first binary codes corresponding to the layout file by the binary codes of the storage paths in the compiled file; then acquiring a first R file included in the compiled file; and finally, creating a second R file in the compiled file according to the first R file so as to generate an installation package file corresponding to the application. Therefore, the layout files in the installation package are taken out of the installation package and are independently stored, the newly created R files are used for replacing the R files automatically generated by the system after the project files are packed and compiled, the size of the application installation package is reduced, the space occupied by the application installation package and the flow consumed in the downloading process are saved, the downloading speed and the application utilization rate of the application installation package are improved, and the user experience is improved.
According to the analysis, the layout files in the installation package can be taken out of the installation package and stored independently, and the newly created R files are used for replacing the R files automatically generated by the system after the project files are packed and compiled, so that the installation package files corresponding to the application are generated. In practical application, after downloading the installation package corresponding to the application, the user needs to obtain the replaced layout file to complete installation of the application, and the method for reducing the application installation package provided by the present application is further described below with reference to fig. 2.
FIG. 2 is a flow diagram of a method of reducing application installation packages in accordance with another embodiment of the present invention.
As shown in fig. 2, the method for reducing application installation packages includes:
step 201, packaging and compiling the project files corresponding to the application to generate a compiled file corresponding to the application.
Step 202, storing the first binary code corresponding to the layout file in the compiled file according to a preset storage path.
Step 203, determine the path header by reflection.
And 204, replacing the first binary code corresponding to the layout file with the binary code of the path header and the binary code of the storage path in the compiled file.
Step 205, obtaining a first R file included in the compiled file.
Step 206, create a class file in the compiled file.
And step 207, copying the content in the first R file into the class file, and generating a second R file so as to generate an installation package file corresponding to the application.
The detailed implementation process and principle of steps 201 to 207 may refer to the detailed description of steps 101 to 104 in the above embodiments, and are not described herein again.
And 208, receiving a layout file acquisition request sent by the terminal, wherein the acquisition request comprises a second R file and a storage path.
The second R file and the storage path included in the acquisition request may be in a binary code form or other forms, which is not limited herein.
Step 209, obtain the second binary code of the layout file corresponding to the storage path and the second R file.
It can be understood that, according to the installation package file corresponding to the application generated in the above step, the binary code and the second R file of the storage path are respectively used to replace the first binary code corresponding to the layout file and the first R file containing the resource ID automatically generated by the system, and when the application is installed by using the application installation package, a file that may need to be replaced may be needed.
The obtaining request comprises a storage path of a layout file stored in a preset storage position and required by the installation application and a second R file containing a resource ID.
In specific implementation, after the storage path and the second R file are obtained, each binary code corresponding to each layout file in the storage path can be obtained by accessing the storage path, and the second binary code of the layout file corresponding to the resource ID is obtained by the resource ID in the second R file.
And step 210, sending the second binary code to the terminal.
Specifically, after the second binary code of the layout file corresponding to the storage path and the second R file is obtained, the second binary code is sent to the terminal, so that the terminal operates the second binary code to obtain the corresponding layout file, thereby completing application installation.
For example, assuming that the binary code of the cookie generated by the storage path is used to replace the first binary code corresponding to each layout file to generate the installation package file corresponding to the application, when the application is installed by using the application installation package, each binary code stored in the storage path can be parsed by using openXmlResourceParser of the XML parser of Android to obtain the corresponding layout file according to the binary code of the cookie, and then the corresponding sub-layout file can be obtained by using the findViewByid method of the second R file, so that the application is installed by using each layout file.
According to the method for reducing the application installation package, provided by the embodiment of the invention, the layout file in the installation package is taken out from the installation package and is independently stored, the newly created R file is used for replacing the R file automatically generated by the system after the project file is packaged and compiled, after the installation package file corresponding to the application is generated, if a layout file acquisition request sent by the terminal is received, the second binary code of the layout file corresponding to the storage path and the second R file is acquired, and the second binary code is sent to the terminal. Therefore, the layout files in the installation package are taken out of the installation package and are independently stored, the newly created R files are used for replacing the R files which are automatically generated by the system after the project files are packaged and compiled, and the layout files are obtained by using the storage path and the newly created R files after the layout file obtaining request sent by the terminal is received, so that the size of the application installation package is reduced, the space occupied by the application installation package and the flow consumed in the downloading process are saved, the downloading speed of the application installation package and the utilization rate of the application are improved, and the user experience is improved.
