Embodiment two
Embodiments provide a kind of method generating application installation kit, see Fig. 2, method flow comprises:
201: by application installation kit decompression, obtain in application installation kit and include the executable file of the logic of application and the first file except executable file.
Wherein, the installation kit of Android application typically uses ZIP compressed file format, therefore can decompress according to the installation kit of normal ZIP decompression mode to this application, the various files be applied in installation kit.
Wherein, the necessary file meeting Android regulation must be comprised in the file in application installation kit, the dynamic link library file write by other language (such as: C Plus Plus) can also be comprised.Android application is write primarily of JAVA language, but because JAVA language can not complete some functions be combined with system, because herein is provided the scheme realized by other language, and stated by Native method, in order to state that the method is not that JAVA language realizes, and need to call dynamic link library file to call to load method corresponding to dynamic link library.
202: in the code of executable file, amendment realizes the Examples of types of claims of the function of applied logic, and is encrypted by code corresponding for the function realizing applied logic.
Wherein, for the Examples of types of claims of Modification growth function, need the function list that different needs amendments can corresponding be set according to dissimilar application in advance.Such as: for communication class application, then the function of communication class is chosen as the function in the function list of the corresponding needs amendment arranged of such application.
Wherein, step 202 can be specially:
2021: decompiling executable file, obtain the code of executable file.
Wherein, executable file is the classes.dex file in installation kit.
2022: in the code of executable file, the Examples of types of claims of the function realizing applied logic is revised as the Examples of types of claims calling function in dynamic link library.
Wherein, in order to the code of the installation kit file of protection application is not revised by other developers, the embodiment of the present invention is by again stating the function realizing applied logic in application and encrypt, to make other developer's None-identifieds and to revise code.In embodiments of the present invention, after Examples of types of claims being modified by the mode of method step 202, if this application is revised by other developers and after repacking, is cannot find corresponding function according to this amended Examples of types of claims, therefore cannot be normally performed by system.
Wherein, the mode of concrete modification Examples of types of claims is: Examples of types of claims corresponding for function in normal JAVA is revised as Examples of types of claims corresponding to Native method, and the Examples of types of claims that wherein Native method is corresponding is Examples of types of claims corresponding to the function called in dynamic link library.
Illustrate: in class HelloWorld, have a function displayHelloWorld.
Original claim is: public void displayHelloWorld ();
Be revised as: public native void displayHelloWorld ().
If after the code in the installation file of this application is modified, when cannot carry out reducing correct Examples of types of claims, system then can go to search corresponding dynamic link library file according to Native method, and when finding and load dynamic link library, then can normally run this application.
2023: according to the cryptographic algorithm preset, code corresponding for the function realizing applied logic is encrypted.

Carry out recording and saving as positional information for the location revision of the function of amendment in step 2022, wherein location revision can be the line number in code, and this positional information does not limit.After saving positional information, this positional information is stored in the preset memory locations of code, to carry out the reduction of Examples of types of claims by searching positional information when performing this application.
2025: the executable file that the code building compiling executable file is modified.
Wherein, this process is the step regenerating amended classes.dex.
203: obtain the Install and configure file in the first file.
204: in the preset field of Install and configure file, be added into the code calling default dynamic link library.
Wherein, the file that the dynamic link libraries added in step 204 is corresponding, calls the dynamic link library Examples of types of claims that also original function is corresponding in advance time in embodiments of the present invention to make execution apply and the code corresponding to function is decrypted.
Wherein, in the preset field of Install and configure file, in step 204, be added into the process of the code calling default dynamic link library, can be specially:
2041: judge whether have preset field in Install and configure file.
Wherein, judge whether to there is preset field, be at AndroidManifest.xml(Install and configure file) search whether there is application joint in file, and whether there is android:name attribute field in the field.
2042: if there is preset field, be then added into the code calling default dynamic link library in the category information of specifying in preset field.
Wherein, preset field in Install and configure information is applied in the operation entrance be executed in Android operation system, the content arranged in this preset field can be first called when applying execution, therefore added by the code calling default dynamic link library in the category information of specifying, this dynamic link library also can be called by this category information of specifying of first calling when applying and performing.
2043: if there is not preset field, be then added into preset field at Install and configure document allocation and in preset field, add the category information of specifying, in the category information of specifying in preset field, being added into the code calling default dynamic link library.
205: by the first file, amended executable file and default dynamic link library, repack and generate application installation kit corresponding to application.
Wherein dynamic link library is for reducing Examples of types of claims corresponding to the function that realizes applied logic, and the code corresponding to the function realizing applied logic is decrypted.
File corresponding for the dynamic link library of amended classes.dex file, AndroidManifest.xml, interpolation and other unmodified files are repacked the application installation kit generating this application.
The embodiment of the present invention realizes the Examples of types of claims of the function of applied logic and encrypts code corresponding to this function by the executable file including the logic of application in amendment application installation kit, to regenerate this application installation kit.Can the logic realizing this application in hiden application installation kit, cannot be revised by other staff, improve the security of application.
