參見圖1，本發明之第一實施例的生成應用程式安裝封包的方法流程圖；該方法流程包括以下步驟：101：通過對應用程式安裝封包解壓縮處理，獲取應用程式安裝封包中包含有應用的邏輯的可執行檔以及除可執行檔以外的第一檔案；102：在可執行檔的代碼中，修改執行應用程式邏輯的函式的宣告類型，並將執行應用程式邏輯的函式對應的代碼進行加密；103：將第一檔案，修改後的可執行檔以及預設 的動態連結程式庫，重新打包生成應用對應的應用程式安裝封包，其中動態連結程式庫用於還原執行應用程式邏輯的函式對應的宣告類型，並對執行應用程式邏輯的函式對應的代碼進行解密。 1 is a flowchart of a method for generating an application installation package according to a first embodiment of the present invention; the method process includes the following steps: 101: obtaining an application installation package by using an application package decompression process Logic executable file and a first file other than the executable file; 102: in the code of the executable file, modifying the declaration type of the function executing the application logic, and corresponding to the function executing the application logic The code is encrypted; 103: the first file, the modified executable file and the preset The dynamic link library is repackaged to generate an application installation package corresponding to the application, wherein the dynamic link library is used to restore the declaration type corresponding to the function executing the application logic, and the code corresponding to the function executing the application logic is performed. Decrypt.

本發明實施例通過修改應用程式安裝封包中包含有應用的邏輯的可執行檔執行應用程式邏輯的函式的宣告類型並加密該函式對應的代碼，以重新生成該應用程式安裝封包。可以隱藏應用程式安裝封包中的執行該應用的邏輯，無法被其他人員修改，提高了應用的安全性。 The embodiment of the present invention regenerates the application installation package by modifying the declaration type of the function of the application logic by modifying the executable file of the application containing the logic of the application and encrypting the code corresponding to the function. The logic for executing the application in the application installation package can be hidden and cannot be modified by other people, which improves the security of the application.

參見圖2，本發明之第二實施例的生成應用程式安裝封包的方法流程圖；該方法流程包括以下步驟： Referring to FIG. 2, a flowchart of a method for generating an application installation package according to a second embodiment of the present invention; the method flow includes the following steps:

201：通過對應用程式安裝封包解壓縮處理，獲取應用程式安裝封包中包含有應用的邏輯的可執行檔以及除可執行檔以外的第一檔案。 201: Obtain an executable file containing the logic of the application in the application installation package and a first file other than the executable file by decapsulating the application installation package.

其中，Android應用的安裝封包通常是使用ZIP壓縮檔案格式，因此可以按照正常ZIP解壓縮處理方式對該應用的安裝封包進行解壓縮，得到應用程式安裝封包中的各種檔案。 The installation package of the Android application usually uses the ZIP compression file format, so the installation package of the application can be decompressed according to the normal ZIP decompression processing method, and various files in the application installation package are obtained.

其中，應用程式安裝封包中的檔案中必須要包含符合Android規定的必要檔案，還可以包含通過其他程式語言(例如：C++程式語言)編寫的動態連結程式庫檔案。Android應用主要由JAVA程式語言來進行編寫，但是由於JAVA程式語言不能夠完成一些與系統結合的功能，因此提供了通過其他語言來執行的方案，並通過Native方法進行宣告，用以宣告該方法不是JAVA程式語言執行，並需要調用動態連結程式庫檔案來調用加載動態連結程式庫對應的方法。 Among them, the files in the application installation package must contain the necessary files that meet the Android rules, and can also include dynamic link library files written in other programming languages (for example, C++ programming language). Android applications are mainly written by the JAVA programming language, but because the JAVA programming language can not complete some functions combined with the system, it provides a solution implemented by other languages, and is declared by the Native method to declare that the method is not The JAVA programming language executes and needs to call the dynamic link library file to call the method corresponding to loading the dynamic link library.

202：在可執行檔的代碼中，修改執行應用程式邏輯的函式的宣告類型，並將執行應用程式邏輯的函式對應的代碼進行加密。 202: In the code of the executable file, modify the declaration type of the function that executes the application logic, and encrypt the code corresponding to the function that executes the application logic.

其中，對於修改函式的宣告類型，需要預先根據不同類型的應用會對應設置不同的需要修改的函式列表。例如：對於通信類應用，則選取通信類的函式作為該類應用對應設置的需要修改的函式列表中的函式。 For the declaration type of the modification function, it is necessary to set different function lists to be modified according to different types of applications in advance. For example, for a communication application, the function of the communication class is selected as a function in the function list that needs to be modified correspondingly set by the application.

其中，步驟202可以包括下列步驟： Wherein, step 202 can include the following steps:

2021：反編譯可執行檔，得到可執行檔的代碼。 2021: Decompile the executable file to get the code for the executable file.

其中，可執行檔為安裝封包中的classes.dex檔案。 Among them, the executable file is the classes.dex file in the installation package.

2022：在可執行檔的代碼中，將執行應用程式邏輯的函式的宣告類型修改為調用動態連結程式庫中函式的宣告類型。 2022: In the code of the executable file, the declaration type of the function executing the application logic is modified to call the declaration type of the function in the dynamic link library.

其中，為了保護應用的安裝封包中檔案的代碼不被其他開發人員修改，本發明實施例通過將應用中執行應用程式邏輯的函式進行重新宣告並加密，以使其他開發人員無法識別並修改代碼。在本發明實施例中，通過方法步驟202的方式將宣告類型被修改後，該應用如果再被其他開發人員修改並重新打包後，是無法根據該修改後的宣告類型找到對應的函式，因此無法正常被系統執行。 In order to protect the code of the archive in the installation package of the application from being modified by other developers, the embodiment of the present invention re-advertises and encrypts the function of executing the application logic in the application, so that other developers cannot identify and modify the code. . In the embodiment of the present invention, after the announcement type is modified by the method step 202, if the application is modified and repackaged by other developers, the corresponding function cannot be found according to the modified announcement type. Cannot be executed by the system normally.

其中，修改宣告類型的方式為：將正常的JAVA中函式對應的宣告類型修改為Native方法對應的宣告類型，其中Native方法對應的宣告類型即為調用動態連結程式庫中的函式對應的宣告類型。 The manner of modifying the declaration type is: modifying the declaration type corresponding to the function in the normal JAVA to the declaration type corresponding to the Native method, wherein the declaration type corresponding to the Native method is the declaration corresponding to the function in the dynamic link library. Types of.

舉例說明：在類HelloWorld中有一個函式 displayHello World。 For example: there is a function in the class HelloWorld displayHello World.

原始宣告為：(public void displayHello World)；修改為：(public native void displayHello World)。 The original declaration is: (public void displayHello World); modified to: (public native void displayHello World).

如果該應用的安裝檔案中的代碼被修改後，無法進行還原正確的宣告類型時，系統則會根據Native方法去查找對應的動態連結程式庫檔案，而在無法找到並加載動態連結程式庫時，則會無法正常運行該應用。 If the code in the installation file of the application is modified and the correct declaration type cannot be restored, the system will search for the corresponding dynamic link library file according to the Native method, and when the dynamic link library cannot be found and loaded, The app will not run properly.

2023：根據預設的加密算法，將執行應用程式邏輯的函式對應的代碼進行加密。 2023: Encrypt the code corresponding to the function executing the application logic according to a preset encryption algorithm.

2024：記錄被修改的執行應用程式邏輯的函式對應的宣告類型的位置信息，並將位置信息存儲於可執行檔的代碼中的預設存儲位置。 2024: Record the location information of the declared type corresponding to the function of the modified execution application logic, and store the location information in a preset storage location in the code of the executable file.

對於步驟2022中修改的函式的修改位置進行記錄並保存為位置信息，其中修改位置可以為在代碼中的行數，該位置信息並不進行限定。保存了位置信息後，將該位置信息存儲於代碼的預設存儲位置，以在執行該應用時通過查找位置信息進行宣告類型的還原。 The modified position of the function modified in step 2022 is recorded and saved as position information, wherein the modified position may be the number of lines in the code, and the position information is not limited. After the location information is saved, the location information is stored in a preset storage location of the code to restore the announcement type by searching for the location information when the application is executed.

2025：編譯可執行檔的代碼生成被修改的可執行檔，此為重新生成修改後的classes.dex的步驟。 2025: The code that compiles the executable file generates the modified executable file, which is the step of regenerating the modified classes.dex.

203：獲取第一檔案中的安裝配置檔案。 203: Obtain an installation configuration file in the first file.

204：在安裝配置檔案的預設字段中添加入調用預設的動態連結程式庫的代碼。 204: Add the code for calling the preset dynamic link library in the preset field of the installation configuration file.

其中，步驟204中添加的動態連結程式庫對應的檔案，在本發明實施例中以使執行應用程式時預先調用動態連結程式庫還原函式對應的宣告類型並對函式對應的代碼進行解密。 The file corresponding to the dynamic link library added in step 204 is used in the embodiment of the present invention to pre-call the declaration type corresponding to the dynamic link library restore function and decrypt the code corresponding to the function.

其中，步驟204中在安裝配置檔案的預設字段中添加入調用預設的動態連結程式庫的代碼的過程，可以具體為： The process of adding the code of the preset dynamic link library in the preset field of the installation configuration file in step 204 may be specifically as follows:

2041：判斷安裝配置檔案中是否存在有預設字段。 2041: Determine whether there is a preset field in the installation configuration file.

其中，判斷是否存在預設字段，即為在AndroidManifest.xml(安裝配置檔案)檔案中查找是否存在application節，以及在該字段中是否存在android：name屬性字段。 Wherein, it is determined whether there is a preset field, that is, whether the application section exists in the AndroidManifest.xml (installation configuration file) file, and whether the android:name attribute field exists in the field.

2042：如果存在預設字段，則在預設字段中指定的類信息中添加入調用預設的動態連結程式庫的代碼。 2042: If there is a preset field, the code that calls the preset dynamic link library is added to the class information specified in the preset field.

其中，安裝配置信息中的預設字段是應用在被執行在Android操作系統中的運行入口，該預設字段中設置的內容會在應用執行時首先被調用，因此將調用預設的動態連結程式庫的代碼加入指定的類信息中，該動態連結程式庫也會在應用執行時會被首先調用的該指定的類信息中進行調用。 The preset field in the installation configuration information is an operation entry that is executed in the Android operating system, and the content set in the preset field is first called when the application is executed, so the preset dynamic link program is called. The code of the library is added to the specified class information, and the dynamic link library is also called in the specified class information that is first called when the application is executed.

2043：如果未存在預設字段，則在安裝配置檔案中指定位置添加入預設字段並預設字段中加入指定的類信息，在預設字段中指定的類信息中添加入調用預設的動態連結程式庫的代碼。 2043: If the preset field does not exist, add the specified field in the specified location in the installation configuration file and add the specified class information in the preset field, and add the dynamic of the calling preset to the class information specified in the preset field. The code to link the library.

205：將第一檔案，修改後的可執行檔以及預設的動態連結程式庫，重新打包生成應用對應的應用程式安裝封包。 205: Repackage the first file, the modified executable file, and the preset dynamic link library to generate an application installation package corresponding to the application.

其中動態連結程式庫用於還原執行應用程式邏輯的函式對應的宣告類型，並對執行應用程式邏輯的函式對應的代碼進行解密。 The dynamic link library is used to restore the declaration type corresponding to the function executing the application logic, and decrypt the code corresponding to the function executing the application logic.

將修改後的classes.dex檔案、AndroidManifest.xml、添加的動態連結程式庫對應的檔案以及其他未修改的檔案重新打包生成該應用的應用程式安裝封包。 The modified classes.dex file, AndroidManifest.xml, the files corresponding to the added dynamic link library, and other unmodified files are repackaged to generate the application installation package of the application.

本發明實施例通過修改應用程式安裝封包中包含有應用的邏輯的可執行檔執行應用程式邏輯的函式的宣告類型並加密該函式對應的代碼，以重新生成該應用程式安裝封包。可以隱藏應用程式安裝封包中的執行該應用的邏輯，無法被其他人員修改，提高了應用的安全性。 The embodiment of the present invention regenerates the application installation package by modifying the declaration type of the function of the application logic by modifying the executable file of the application containing the logic of the application and encrypting the code corresponding to the function. The logic for executing the application in the application installation package can be hidden and cannot be modified by other people, which improves the security of the application.

參見圖3，本發明之第三實施例的執行應用程式的方法流程圖，該方法流程包括以下步驟：301：在系統運行應用程式安裝封包時，獲取應用程式安裝封包中的包含有應用的邏輯的可執行檔，除可執行檔以外的第一檔案以及預設的動態連結程式庫；302：調用動態連結程式庫，在可執行檔的代碼中還原執行應用程式邏輯的函式的宣告類型，並將執行應用程式邏輯的函式對應的代碼進行解密；303：根據第一檔案，修改後的可執行檔執行應用程式。 Referring to FIG. 3, a flowchart of a method for executing an application according to a third embodiment of the present invention includes the following steps: 301: Obtaining an application-containing logic in an application installation package when the system runs an application installation package. The executable file, the first file except the executable file and the preset dynamic link library; 302: calling the dynamic link library, and restoring the declaration type of the function executing the application logic in the code of the executable file, And decrypting the code corresponding to the function executing the application logic; 303: executing the application according to the modified file in the first file.

本發明實施例執行重新打包的應用程式安裝封包時，通過預設的動態連結程式庫將原有被修改過宣告類型的包含有應用的邏輯的可執行檔執行應用程式邏輯的函式進行還原，並進行解密還原出原始的應用程式安裝封包，以執行經過安全加密的應用，提高了應用的安全性。 When the repackaged application installation package is executed, the embodiment of the present invention restores the function of executing the application logic of the executable file containing the application logic by using the preset dynamic link library.
