Problems solved by technology

Usually, the Android system itself has permission management. When operating the mobile client, the tester needs to have the corresponding operation permission, otherwise the mobile client cannot perform the corresponding operation.
[0003] Different from pulling ordinary files such as pictures and music, due to the particularity of system file content and storage location, pulling system files requires higher permissions. Therefore, if the tester has insufficient operating permissions, the system files cannot be pulled to the PC.
In addition, when pulling a system folder containing multiple system files as a whole, the mobile client needs to access all the system files in the system folder one by one and build a file list. If the tester does not have access to the system files permissions, the mobile client cannot access the system files, resulting in no system files that can be pulled in the established file list, which in turn leads to the failure of pulling the system folder

Embodiment Construction

[0027] The following will clearly and completely describe the technical solution in this embodiment with reference to the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] Before describing this embodiment, a brief introduction to system files is given first. At present, the industry believes that except for files stored on an external memory card, all files stored in the internal storage area of ​​the mobile phone can be called system files. Typical system folder paths include:

[0029] 1) / system / app, the path points to the read-only memory (Read Only Memory, ROM for short) of the mobile phone, which is used to store the system application of the mobile phone. Usually,...

Abstract

The invention discloses a file pulling method, device and system, and relates to the technical field of communication. A system file in a mobile client can be successfully pulled to a PC (Personal Computer). The file pulling method comprises the following steps that the mobile client obtains a superuser (root) privilege which is the highest privilege of the mobile client; under the root privilege, the system file is copied to an external storage region from an internal storage region, and the access privilege of the system file in the external storage region is lower than that of the system file in the internal storage region; under the operation privilege of the PC, the system file in the external storage region is sent to the PC. The file pulling method, device and system provided by the invention are mainly applied to the process of detecting a mobile phone system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for pulling files. Background technique [0002] When testers detect mobile clients such as mobile phones and tablet computers, they need to pull the system files in the mobile client to a computer (Personal Computer, referred to as PC), and run and detect the system files on the PC, so that Complete the system test on the mobile client. Usually, the Android system itself has permission management. When the tester operates the mobile client, he needs to have the corresponding operation permission, otherwise the mobile client cannot perform the corresponding operation. [0003] Different from pulling pictures, music and other ordinary files, due to the particularity of system file content and storage location, pulling system files requires higher permissions. Therefore, if the tester does not have enough operating permissions, the system...
