Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] Such as figure 1 As shown, an android application anti-piracy method includes the following steps:

[0037] S10: Split the android application program into two parts of code: add a stub class (Stub.java) code into code 1 and compile it into generated file 1; compile code 2 into generated file 2, and upload the two parts of the file to the server;

[0038] Such as figure 2 As shown, in this embodiment, it is preferable to split the android application source code 10 into the following two parts: the second file is the key source code 13 of the application program, which can be the startup ...

Abstract

The invention provides an anti-piracy method and system for an android application. The method comprises the following steps: partitioning the android application into two parts: a key program and an incomplete partial application, wherein normal running is unavailable unless the two parts are combined; uploading the two parts to a server, encrypting a key code by the server, and applying for the key program from the server at the first-time run after a user downloads the incomplete partial application; downloading the key program after receiving authentication of the server, decrypting the key program on a client, storing in a safe space, and loading the key program after lawful authority is judged so as to run the application normally; after the first-time run, storing the key program in the safe space and running each time without downloading from the server. According to the method and the system, the application can be effectively prevented from being subjected to reverse engineering and piracy without increasing the workload of a developer.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method and system for preventing piracy of android application programs. Background technique [0002] With the rapid development of the mobile Internet, mobile terminal operating systems have formed two main camps, ios and android. The application program based on the android operating system adopts the mainstream programming language Java. Java programs are compiled to generate bytecodes that run on virtual machines. For the android system, the application program written in Java is compiled and run on the DEX bytecode on DalvikVM, and all the bytecode files of the application program are packaged into APK files and installed on the android system. At present, Java programming language tools do not take effective protection measures for Java bytecode, and the structure of Java bytecode file itself makes it easy to be reverse engineered, so there is a source code se...
