Call method, device and electronic equipment of non-public library in mobile terminal

Abstract

The application proposes a calling method, device, electronic equipment and storage medium of a non-public library in a mobile terminal, belonging to the technical field of computer applications. The method includes: obtaining the call request of the application program, the call request includes the identification of the application program and the identification of the non-public library; according to the identification of the application program, obtaining the return address of the application program; writing the jump function into the address corresponding to the preset address In the memory, the target address of the jump function is the return address, and the default address is the legal address of the operating system in the mobile terminal; modify the return address to the default address; call the non-public library according to the default address and the identification of the non-public library The system interface function corresponding to the library to open the non-public library. Therefore, through this method of calling the non-public library in the mobile terminal, it is possible to bypass the system's restriction on the dynamic link of the non-public library for the application, not only does not need to read and parse the file, the link speed is fast, and the non-public library can be loaded now library, improving usability.

Description

Technical field [0001] The present application relates to the field of computer applications, in particular, to a method, apparatus, electronic device, and storage medium in a non-public library in a mobile terminal. Background technique [0002] Starting with Android 7.0, the system blocks the application dynamic link non-public NDK library to improve the security of the system. However, for some special needs, such as insert, hot repair, etc., there is a need to dynamically link non-public libraries, and therefore need to bypass the system. [0003] In the existing related techniques, by reading the SO file under the / proc / directory, parse the reposition table in the SO file (ELF format), use the SO base address plus the address in the relocation table, calculate the desired Call the address of the function to achieve the purpose of calling the non-public NDK library function. However, this method needs to read and resolve the SO file, not only slower, but only the non-publi...

Problems solved by technology

[0004] The calling method, device, electronic equipment and storage medium of the non-public library in the mobile terminal proposed by this application are used to solve the related technology. The existing method of bypassing the system dynamic link non-public library restriction needs to read and parse the so file , not only slow, but also only applicable to non-public libraries that have already been loaded, and the problem of poor practicability
