Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides a method for generating an application installation package, which is applied to an Android system, where an execution main body of the method for generating an application installation package may be an application development side client, as shown in fig. 1, and the method includes:
step 101: and acquiring installation resources of the application program.
Step 102: and analyzing the first resource for loading the main interface of the application program from the installation resource.
Specifically, after the application program is developed, the installation resources of the application program can be obtained according to the developed application program, and the installation resources of the application program include resources required for the direct operation of the application program and resources not required for the direct operation of the application program, where the resources required for the direct operation of the application program at least include resources for loading a main interface of the application program, and thus, in step 102, the resources for loading the main interface of the application program can be analyzed from the installation resources as the first resources. In a special case, the application program has a start page when running directly, and then, in step 102, the resources for loading the start page and the main interface of the application program can be analyzed from the installation resources as the first resources.
Step 103: and generating an application program installation package according to the first resource.
Specifically, the file format of the application installation package is apk (android package). After the application program installation package is generated according to the first resource, the application program can be installed according to the application program installation package, the main interface is loaded by the application program after the installed application program is opened, and when the application program has the start page, the start page and the main interface are sequentially loaded by the application program.
Further, after parsing out the first resource for loading the main interface of the application from the installation resource, the method further includes: and temporarily storing a second resource except the first resource in the installation resources into an asset directory.
Specifically, the resources other than the resources required for the direct running of the application are the resources that are not required for the direct running of the application, where the resources that are not required for the direct running of the application include resources for loading a secondary interface of the application. In the application, after the first resource is analyzed, the second resource except the first resource in the installation resource is temporarily stored in the asset directories (Assets directories), so that the problem of resource conflict caused by storing the second resource in the resource file directory (Res directory) can be avoided.
Specifically, the files in the Assets directory are accessed by file names, that is, the Resources object is obtained first, then the Assets directory is obtained by calling the getAssets method according to the Resources object, and then the open method is called to read the specified files.
Further, after parsing out the first resource for loading the main interface of the application from the installation resource, the method further includes: and generating a resource installation package according to a second resource except the first resource in the installation resources.
Specifically, in the present application, after a first resource for loading a main interface of an application is parsed from an installation resource, a second resource other than the first resource in the installation resource may be directly packaged into a resource installation package, or the second resource may be temporarily stored in an Assets directory and then packaged into the resource installation package. And the file format of the resource installation package is also APK. After the resource installation package is generated, the resource installation package is sent to a server.
Further, in order to improve the security of the resource installation package and prevent the resource installation package from being stolen or modified in the transmission process, in the application, file signatures can be carried out on the application program installation package and the resource installation package, so that the file signature of the application program installation package is consistent with the file signature of the resource installation package, and the resource installation package is guaranteed to be effective on the application program installation package only when the file signature of the resource installation package is consistent with the file signature of the application program installation package. In addition, the application installation package and the resource installation package can be encrypted, and the file signature process and the encryption process can be combined to ensure the safety of the resource installation package.
Further, the application executes two encryption processes when encrypting the application installation package and the resource installation package. The client at the application development side can be used for encrypting the application installation package and the resource installation package, and the server can be used for encrypting the application installation package and the resource installation package. In the present application, the installation package is encrypted using a key pair, one key pair comprising a public key and a private key. The first key pair and the second key pair used for encryption may be generated in the client on the application development side or in the server, and the first key pair and the second key pair may be mutually transmitted between the client on the application development side and the server.
In general, the asymmetric encryption algorithm is to encrypt and decrypt using a public key by using a private key, but there may be a case that a man-in-the-middle forges a server in a transmission process, the forged server provides a forged resource installation package to a client, and the forged resource installation package contains a malicious advertisement, so that in the present application, the encryption is performed in a reverse direction, that is, the encryption is performed using the private key and the decryption is performed using the public key, specifically:
when the client side of the application development side is used for encryption, firstly, the client side of the application development side stores a first public key in a first key pair into an application installation package, and simultaneously, a first private key in the first key pair is used for carrying out first encryption on a resource installation package, then, the client side of the application development side stores a second private key in a second key pair into the application installation package, and simultaneously, a second public key in the second key pair is used for carrying out second encryption on the resource installation package. After completing the encryption twice, the client on the application development side can send the resource installation package to the server.
When the resource installation package is encrypted by the server, the resource installation package is sent to the server after the resource installation package is generated, then the server end encrypts the resource installation package by using a first private key in a first key pair, and simultaneously a first public key in the first key pair is stored in the application program installation package, so that the resource installation package which can be decrypted by only the first public key in the application program installation package can be ensured to be transmitted by the server, as the first private key corresponding to the first public key is only held by the server and cannot be forged by a middleman, the resource installation package cannot be stolen by a third party, as the first public key is public, and further the resource installation package is encrypted for the second time, specifically, the server encrypts the resource installation package by using a second public key in a second key pair, meanwhile, the second private key in the second key pair is stored in the application program installation package, so that the resource installation package can be decrypted only by the application program installation package holding the second private key, and a third party can only encrypt and cannot decrypt even if holding the second public key.
Based on the same inventive concept, an embodiment of the present invention further provides a method for loading an application installation package, which is applied to an Android system, where an execution main body of the method for loading an application installation package may be an application user side client, as shown in fig. 2, and the method includes:
step 201: the method comprises the steps of obtaining an application program installation package generated according to a first resource, wherein the first resource is used for loading a main interface of an application program.
Specifically, the acquisition path of the application installation package may be an application development side client, or may be any software download website.
Step 202: and installing the application program according to the application program installation package so that the main interface can be loaded when the user opens the application program.
In the application, after the application is installed by using the application installation package generated according to the first resource, the user opens the installed application, and then the application use side client loads the main interface and displays the main interface of the application to the user.
Further, when the current display interface of the application program is a main interface, whether an opening operation for opening a secondary interface in the main interface exists is judged, and when the opening operation exists, a resource installation package stored in a server is obtained and loaded. Specifically, the client on the application program using side sends a resource obtaining request to the server, and the server sends the resource installation package to the client on the application program using side after receiving the resource obtaining request, and stores the resource installation package in a file directory of the application program.
Further, after the resource installation package stored in the server is obtained, the method further includes:
decrypting the resource installation package encrypted by the second public key in the second key pair for the first time by using a second private key in the second key pair stored in the application installation package;
and carrying out secondary decryption on the resource installation package encrypted by the first private key in the first key pair by using the first public key pair in the first key pair stored in the application program installation package.
Specifically, after the resource installation package is obtained, corresponding to the encryption process, first, the resource installation package is decrypted for the first time by using the second private key of the second key pair, after the decryption is successful, the resource installation package becomes a file encrypted by the first key pair, then, the resource installation package is decrypted for the second time by using the first public key of the first key pair, and finally, the resource installation package without the password is obtained.
In addition, after decrypting the resource installation package for the second time by using the first public key of the first key pair, the method may further include: and judging whether the file signature of the resource installation package is consistent with the file signature of the application program installation package, if so, loading the resource installation package, and otherwise, deleting the resource installation package.
Further, when acquiring a file signature, acquiring a package management service object of android by a context package manager method, acquiring an applied package info object by a getPackageInfo method of the object, acquiring signature information of an installation package by a signatures field of the object, directly acquiring a self-defined Resources object by a getAssesses method when an opening operation for opening a secondary interface exists, acquiring a management object of an Assets directory by calling the getAssesses method, and finally calling an open method to acquire a specified resource file, wherein a parameter of the open method is a resource file name, and finally setting Resources in an application program.
Further, the class for directly operating the resource in the android system is Resources, and the resource except the installation package cannot be loaded directly through the Resources class, because the Resources are verified, when the installation package is not an installed installation package, the resource is not read, and the Resources class finally loads the resource of the specified path installation package through addasstapath of an assetmager class, wherein the assetmager class is an android resource manager class, all the Resources in the android are realized through the addasstapath, and only an own Resources object can be created when the resource package which is not installed is read, but a construction method for creating the Resources class needs to introduce an assetmager object, and a construction function of the assetmager object is set to be hidden by the system, so that an assetmager object needs to be constructed through reflection.
The process of reflection creating an AssetManager object is as follows: firstly, obtaining a type object clazz of an AssetManager Class by a forName method of the Class, wherein the Class is a Class which represents all classes in java, it provides many functions for java class reflection, which accepts a string description of a class, the AssetManager class package name "android. Then calling the getConstructor method of clazz to obtain the construction method of the AssetManager class, finally calling the newInstance () method to create an AssetManager object, calling the addAssetPath method of the AssetManager object to specify the path of the loading resource after the AssetManager object is created, and the addesstop path is also a hidden method name and also needs to be called by reflection, firstly, a getDescaled method of clazz is called to obtain an object of the addasstop path method, a first parameter of the getDescaled method receives a method character string description needing reflection, i.e., addassetPath, the second parameter is the type of parameter that requires the reflection method, the parameter of the addassetPath method is the path name, the type is String, so the second parameter passes string class, and finally the invoke method of the addasspath method object is called to execute the addasspath method. Wherein invoke is a method calling step in reflection, and when a method is reflected, getDelaredMethod only gets the method object, so it also needs to call invoke the invoke method to actually execute the method to be reflected.
Further, the process of creating custom Resources objects is as follows: the resource class construction needs three parameters, the first is an AssetManager object, and simultaneously, a path of an installation package file is set to be a path of a resource by calling an addassetPath method, the second parameter is an object of a DisplayMetrics class, the DisplayMetrics class can obtain information such as a mobile phone screen size, so that a DisplayMetrics object is directly created, the third parameter is a Configuration object which controls a series of information such as a mobile phone horizontal screen and a mobile phone vertical screen, the DisplayMetrics object is directly obtained and transmitted through a context object in the installation package, namely, a getConfiguration () method is called, the context is a context environment representing an android application program, various environments in which the android program runs can be accessed through the context, and when the self-defined Resources are realized, the Resources are loaded and decrypted to call and read the resource in the resource installation package.
