Method and system used for judging existence of root authority in Android system

Abstract

The invention relates to the field of application interaction and discloses a method for judging if an Android system has a root authority. The method comprises the following steps: S1) acquiring a route of a PATH environment variable of the Android system; S2) traversing documents under the route of the PATH environment variable, judging if a su document is contained in the documents under the route of the PATH environment variable, if yes, indicating that the system has the root authority, and if not, indicating that the system has no root authority; and S3) storing a judging result in step S2) in a data storage interface document, and directly reading the judging result for the root authority in the data storage interface document while judging if the system has the root authority again. The invention also discloses a system for judging if the Android system has the root authority. According to the invention, the judging efficiency for the root authority of the system can be effectively increased.

Description

technical field [0001] The invention relates to the field of application interaction, in particular to a method for judging whether an Android system has root authority and a system for judging whether an Android system has root authority.
