Abstract

Embodiments of the present invention provide a method, device, device, and storage medium for operating system switching. The method is applied to a terminal device running a first operating system and a second operating system. The method includes: responding to the monitored first operating system Switch event, determine whether the first operating system is switched to the foreground or switched to the background; if switched to the background, then release the first multimedia hardware resource occupied by the first type of multimedia application program under the first operating system; release the first operation The second multimedia hardware resource occupied by the second type of multimedia application program under the system, and suspend the data operation of the second type multimedia application program on the second multimedia hardware resource; switch the first operating system to the background operating system , and switch the second operating system to the foreground operating system. According to the technical solutions of the embodiments of the present invention, not only can the problem of mutual exclusion of multimedia hardware resources during system switching be avoided, but also the efficiency of system switching can be improved.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to an operating system switching method, device, equipment and storage medium. Background technique [0002] With the development of computer technology, multiple operating systems can be run on many computers, for example, two Android operating systems can be run on a mobile phone terminal. [0003] In one technical solution, on a dual-system device such as an Android dual-system device, the audio and video frameworks of the two operating systems share unique multimedia hardware resources, including microphones, speakers, and codecs. All user operations are in contact with the foreground operating system. When the foreground operating system uses multimedia hardware resources, it requires the background operating system to release resources. [0004] However, in this technical solution, on the dual-system device, the two systems share the only multimedia hardware resourc...
