Method and system for simultaneously calling camera by multiple applications based on broadcast mechanism

Abstract

The invention belongs to the field of the software technical application, and discloses a method and system for simultaneously calling a camera by multiple applications based on a broadcast mechanism.The method comprises the following steps: S1, receiving a command, which is sent by an application program A, of calling the camera to shoot, and generating a first command serial number, broadcasting the command, which is sent by the application program A, of calling the camera to shoot and the first command serial number; the method further comprises the step S2: receiving a command, which is sent by an application program, of accomplishing the shooting, and generating a second command serial number, and broadcasting the command, which is sent by an application program, of accomplishing theshooting and the second command serial number, wherein the application program B is the application program occupying camera hardware resource, and the system is the system adopting the above method.Through the method disclosed by the invention, the function of simultaneously occupying the camera by multiple applications can be realized when one application program does not understand a shootinginterface of other application program and does not expose the own shooting interface to other application program.

Description

technical field [0001] The invention belongs to the application field of software technology, and more specifically relates to a method and system for simultaneously calling a camera by multiple applications based on a broadcast mechanism. Background technique [0002] At present, in operating systems such as Android and Windows, if the application program that needs to call the camera to take pictures does not know the camera interface of the application program that takes up the hardware resources of the camera, the application program that needs to call the camera to take pictures cannot be synchronized with the application program that takes up the hardware resources of the camera. Occupies camera hardware resources, that is, when an application needs to use the camera continuously, other applications cannot simultaneously call the camera to complete the camera and video functions; if the application that needs to call the camera to take pictures knows the camera interfac...

AI Technical Summary

Problems solved by technology

[0004] This technical solution not only requires the application that needs to call the camera to take pictures and the application that occupies the hardware resources of the camera to understand each other's camera interface Activity, but is limited to the use of Android devices that have already determined the application, and this technical solution is not suitable for calls that need to call the camera. The application that is recording and the application that is occupying the camera is occupying the hardware resources of the camera to record at the same time
