Method and device for obtaining Root permission

Abstract

The embodiment of the invention discloses a method for obtaining a Root permission. The method comprises the following steps that: a terminal opens a native process by using the identity of an SU (Switch User), and a JNI (Java Native Interface) module is started in the native process; the user identity of the native process is set as the ID (Identity) of the SU by the terminal via the JIN module, the operation permission of the SU is obtained, and the security environment variable of a system is cleared; the terminal starts a sub process through the JNI module, and a Jar packet is loaded in the sub process through the operation permission of the SU; and the terminal starts a resident service process of the Jar packet, and the Root permission is obtained through the resident service process. The embodiment of the invention also discloses a device for obtaining the Root permission. After the adoption, the method and the device disclosed by the invention have the advantages that the consumption of resources for obtaining the Root permission can be concretely reduced; the success rate of obtaining the Root permission is improved; the applicability is high; and the experience of a user obtaining the Root permission is enhanced.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and device for obtaining Root authority. Background technique [0002] With the development and maturity of the research and development technology of devices using the Android system such as mobile phones and the increasing number of mobile phones, the types of mobile phone applications are also increasingly diverse. In order to enable mobile phone users to obtain a better user experience, many mobile phone applications need to apply to the system for Root permissions, and realize more functions under the Root permissions. Currently, some mobile phones and other Android device systems provide Root permissions, and the mobile phone needs to obtain Root permissions from the system in order to realize corresponding functions under Root permissions. [0003] In the prior art, when an application program obtains Root authority, it mainly starts its own resident ...

Problems solved by technology

In the prior art, the operation of obtaining Root authority is performed through a service process. Although the Root authority can be obtained, when the system version is higher than Android4.0 and the security monitoring of the system is higher, the method described in the prior art will not Unable to avoid the security monitoring of the system, the application cannot use the Java API to start the user process through app_process, and thus cannot obtain Root privileges

That is, in the prior art, only using the Java API to start the user process through app_process has low applicability and a high failure rate; in addition, in the prior art, the application program needs a service program to perform the operation of obtaining the Root authority every time it applies for the Root authority. Increased resource overhead for obtaining Root permissions
