Android security mechanism (2) Android Permission control mechanism, androidpermission1. Overview Android is a permission separation system. This is to use the existing permission management mechanism in Linux to assign different uid and gid to each Application, this allows private data and access between different app

permissionUser ID: in Linux, a user ID identifies a given user. In Android, a user ID identifies an application. The application is assigned a user ID during installation. The user id remains unchanged during the lifetime of the application on the device. Permission is about allowing or restricting applications (rather than users) to access device resources.Android uses the sandbox concept to implement separation and permissions between applications

Self-articles are mainly translated articles on the official website, and I have also added my own understanding. If there is any inaccuracy, please correct me.Http://developer.android.com/guide/practices/security.html Some virtual machines run within a security boundary and are isolated from their operating system programs, such as Java virtual machines and. net runtime environments.On android, Dalvik virt

If the UID is 0, the description is the root user, then the permissions are not controlled.2.

Complete analysis of Android security attack and defense, decompilation and obfuscation technologies (I) I have been hesitant to write this article before. After all, it is not proud to decompile other programs. However, from a technical point of view, it is indeed a very useful skill to master the decompilation function, which may not be used very often, that's a headache. In addition, since someone else c
