Description

Fly screen realization method and device for connecting screen, vehicle, medium and product Technical Field The invention relates to the technical field of multi-screen interaction, in particular to a flying screen realization method and device for a continuous screen, a vehicle, a medium and a product. Background With the current increasing richness of automotive interior functions, multi-screen devices are gradually moved into automobiles. Along with the version change, the Android version of the automobile also comes to Android14, and for the version, a screen is connected on some automobile types, the original screen flying scheme is to distinguish different screens according to the display device identifier DISPLAY ID, so that the screen flying function among different screens is realized, and the screen connecting design belongs to a large screen because the screens are not distinguished on the physical level, so that the screen flying function cannot be realized, and therefore, how to realize the screen flying function for two or more screens under the Android system becomes a problem to be solved urgently. Disclosure of Invention The invention provides a method, a device, a vehicle, a medium and a product for realizing a flying screen of a continuous screen, which are used for solving the problem that a flying screen realizing scheme under an android system is difficult to apply to the continuous screen design in the related technology. In a first aspect, the invention provides a method for realizing a fly-screen with a screen, wherein the screen is a screen of an android system, a plurality of applications are deployed on the screen, the screen comprises a first screen and at least one second screen, and the method comprises the following steps: monitoring application stack information in an android system; In response to detecting that the task identifier of the parent desktop application of the target application in the application stack information changes, determining to trigger a fly-screen operation, and acquiring a first task identifier before the parent desktop application changes and a second task identifier after the parent desktop application changes from the application stack information; And respectively switching the audio focus and the audio zone corresponding to the target application from the first screen corresponding to the first task identifier to the second screen corresponding to the second task identifier. According to the invention, by monitoring android system application stack information, task identification change of target application father desktop application is used as a fly screen triggering basis, the limitation of distinguishing screens by using display device identifiers of a plurality of screens in the prior art is broken through, and a screen connection scene is adapted. Meanwhile, after the screen flying is triggered, the audio focus and the voice zone of the target application are synchronously switched, so that the display content is ensured to be transferred, and the audio output and the interactive focus can be seamlessly connected. The method is free from additional hardware assistance, can flexibly expand to multi-screen scenes with more than two screens only by relying on an android system native stack mechanism, meets the requirements of vehicle-mounted continuous-screen multi-screen cooperation, and improves the use smoothness of users in multi-screen interaction. In an optional implementation manner, switching the audio focus corresponding to the target application from the first screen corresponding to the first task identifier to the second screen corresponding to the second task identifier includes: releasing the focus of the target application in a focus stack of a first screen corresponding to the first task identifier; and applying for the focus of the target application in a focus stack of a second screen corresponding to the second task identifier. According to the method and the device, accurate migration of the audio focus is achieved through the mode that the target application focus is released on the first screen focus stack and the focus is reapplied on the second screen focus stack. The process follows the ordered logic of focus management, and avoids abnormal audio interaction caused by focus confusion. And the focus related adaptation development is not required to be carried out on the target application, all focus operations are completed by a system level, so that all three parties and local applications can normally respond to focus switching when flying the screen, the compatibility of different applications is improved, and the application adaptation cost is reduced. In an optional implementation manner, switching the audio region corresponding to the target application from the first screen corresponding to the first task identifier to the second screen corresponding to the second task identifier includes: And removing the bin
