Description
Technical Field
The invention relates to the technical field of computer information, in particular to a dual-system setting item management system based on a Linux kernel and a management method thereof.
Background
A dual-system product developed based on a Linux kernel generally requires two sets of setting applications to set specific setting items in two systems, respectively. The setting application refers to a specific application program with an interface for setting system configuration items. For example, for android, a setting application refers to "setting", specifically to a system-level application program called com. The method is an application program with an interface of a foreground, and the specific setting operation is finished by calling a system setting interface or setting a database.
However, there are often duplicate operations on the same setting item in both operating systems, such as a setting operation on a system time. The user switches the setting application between the two operating systems, and the tedious operation also causes very poor user experience. And in order to manage the respective system setting items, the two systems need to have respective system setting applications, which is a waste of system resources.
Disclosure of Invention

and the first operating system and the second operating system operate respective setting item databases through the setting application in the first operating system.
Furthermore, the setting application has setting item pages of two operating systems, and when the setting application operates the setting item database of the second operating system, the setting application adopts remote call to notify the system service of the second system, and the setting application is realized by the system service of the second system.
Furthermore, the first operating system and the second operating system both include a system service module, where the system service module of the first operating system is used to identify a request of a first operating system application program for setting an application, or identify a request of a second operating system application program for setting an application, which is intercepted and forwarded by a system service of the second operating system, and call a corresponding setting item page according to the request; the system service module of the second operating system is used for monitoring and rejecting a direct operation request of an application program of the second operating system to the setting application, and the operation request is forwarded to the system service of the first operating system.
On the other hand, the invention provides a Linux kernel-based dual-system setting item management method, which is realized based on the management system of the first aspect, and comprises the following steps:
the system service of the first operating system responds to a setting item operation request initiated by a user through the first operating system or a setting item operation request forwarded by the second operating system through the system service, and informs the first operating system of starting a setting application;
the setting application calls setting pages corresponding to different operating systems according to different initiating processes of the operation request and is used for receiving the setting operation of the user;

Further, when the user initiates a setting item operation request through the first operating system, the system service judges the affiliation of the target setting item and the operating system, and selects different management modes according to the affiliation of the target setting item and the operating system.
Further, when a user initiates a setting item operation request through the second operating system, the system service of the second operating system intercepts the request for starting the setting application, rejects the direct operation of the second operating system on the setting item, forwards the operation request to the system service of the first operating system, and the system service of the first operating system judges the affiliated relationship between the target setting item and the operating system and selects different management modes according to the affiliated relationship between the target setting item and the operating system.
Further, selecting different management modes according to the affiliated relationship between the target setting item and the operating system includes:
when the target setting item is a setting item specific to the first operating system, the setting application directly operates a setting item database of the first system and calls a related system interface to complete setting;
when the target setting item is a setting item specific to the second operating system, the setting page receives the setting operation of a user, when the setting application is set by the user, the system service of the first operating system is informed to forward the setting content to the system service in the second operating system, the system service of the second system calls a setting item database to update the setting item data, and calls a system interface in the second operating system according to the change content of the setting item to generate a specific setting result, or directly calls the system interface of the second operating system without passing through the setting item database to generate the specific setting result;
when the target setting item is a setting item shared by the two systems, the setting application completes updating of the setting item database and calling of a system setting interface in the first operating system, and simultaneously informs the system service of the second operating system of completing updating of the setting item database of the second operating system and calling of the system setting interface through forwarding of the system service of the first operating system, so that the setting operation is completed.
Further, when a user initiates a setting item operation request through the second operating system, the operation request includes specific setting intention parameters, the setting application automatically jumps to a specific corresponding setting item page to receive the setting operation of the user, and when the user completes the setting, the setting application directly operates the setting item database of the first system and calls a related system interface to complete the setting.
Furthermore, after the user completes the setting item operation request initiated by the second operating system, the first operating system exits the setting application and automatically switches back to the second operating system.
The invention has the beneficial effects that: only one setting application exists, and the two operating systems carry out system setting through the unified setting application. The unified setting application can improve the use experience of a user and reduce the occupation of the setting application to the disk space of the operating system.
