Abstract

The technical scheme disclosed by the invention includes a camera sharing system and method for multiple applications based on the Android. The camera sharing method for multiple applications based onthe Android comprises the following steps: obtaining the data address of a camera device in the Android system; creating a plurality of virtualized camera devices to perform sharing and correlation on the data address obtained by an address acquisition module, wherein the data address of each virtualized camera device has a unique identifier; obtaining the video data of the camera device throughthe data address by means of the virtualized camera device and sending to the corresponding application; and using the function of the camera device. The camera sharing system and method for multipleapplications based on the Android have the beneficial effect that multiple applications can use the camera device and the camera function in the Android system without the strategy switching of the camera device.

Description

technical field [0001] The invention relates to a system and method for sharing a camera based on Android multi-applications, and belongs to the field of computers. Background technique [0002] in some special application scenarios. For example, if the background is always recording, the camera will be occupied by the recording application all the time, and other applications can no longer open the camera. If other applications want to use the camera, the application that occupies the same camera must be exited first. [0003] At present, there is no good solution in the industry. Some solutions do this: [0004] Solution 1: When an application opens the camera, if the camera is occupied, then force the camera to be given to the application that opened the camera last. It is not shared in essence, but the strategy used by the camera is modified. [0005] Solution 2: Do not change the occupation of the camera, but change the window of the camera preview. Which applicati...
