[0048] Taking the fine-grained authority control security module as an example, the construction method of the Android platform with the pluggable function of the fine-grained authority control security module, the specific implementation process is as follows:
[0049] Fine-grained permission control The security module can control the dangerous permissions of a single application and the combination of multiple applications.
[0050] Step 1 In the four-layer structure of the native Android platform, the intersection point related to the feature points of the fine-grained permission control security module is the checkPermission method of ActivityManagerService, such as figure 2 shown. The Android application framework layer provides a set of authorization mechanisms. When an application accesses resources, permission checks are performed, and only authorized operations are allowed to continue running. The location of the permission check is the checkPermission method of th...
