Detailed Description
The invention discloses a virtual equipment sharing method, which is characterized in that by introducing the logic of video or audio sharing virtual equipment, a user can simultaneously play video or audio through a plurality of different software applications while opening the camera equipment or audio equipment through a first application, so that the multiplexing of the camera equipment or microphone equipment is realized, and the practicability and the scene of a product are effectively improved.
In the Android system, an Android Virtual Device (AVD) is a configuration for defining functions to be used in the Android system, which is a characteristic of an Android mobile phone, a tablet, a Wear OS, an Android TV, or an Android auto OS device. The virtual device (AVD) manager is an interface that can be launched from the Android Studio and is intended to help create and manage AVDs.
Virtual Devices (AVDs) have dedicated storage areas in development computers. Virtual Devices (AVDs) store device user data such as installed applications and settings and emulated SD cards. The AVD Manager can be used to erase the user data as needed so that the corresponding device has the same data as the new device.
The API level of the target device is important because the application will not be able to run on a system image with an API level lower than the level required by the application.
As a first embodiment of the present invention, the present invention discloses a virtual device sharing method, including performing the following steps:
step 1: and installing a virtual equipment manager, and creating and managing virtual equipment through the virtual equipment manager.
Step 2: when the virtual device created in step 1 is used, the virtual device is virtualized into a logical device, and the system uses the logical device as a real device, thereby realizing multi-use of one device.
In said step 1, if an application declares an element in the manifest file, the application needs to have a system image of the external library. If an application is to be run on a simulator, A Virtual Device (AVD) is created that contains the required libraries, for which purpose the virtual device is created using plug-in components that are appropriate for the virtual device platform.
In step 1, creating a virtual device from the copy further includes: on the virtual device page of the virtual device manager, right clicking on the virtual device and selecting Duplicate, the system displays a Verify Configuration page.
If changes are needed on System Image and Select Hardware pages, Change or Previous changes are clicked and Finish is clicked, the Virtual device will be displayed in the Your Virtual Devices page.
As shown in fig. 1, in step 2, the method further includes that the user opens and uses the actual physical device through the first application program, and the specific steps are as follows:
step S1: starting a first application program;
step S2: opening the using equipment;
step S3: calling an equipment API;
step S4: calling a logic device;
step S5: applying for opening the equipment;
step S6: locking device resources is monopolized, and finally the actual physical device is opened, e.g., the actual physical device is a Microphone (MIC).
As shown in fig. 1, in step 2, the step of opening and using the actual physical device by the user through the first application program further includes opening and using the actual physical device through the second application program, and the specific steps are as follows:
step 20: starting a second application program; (including launch application 1 … … application n);
step 21: opening the virtual device; (including opening virtual device 1 … … opening virtual device n);
step 22: calling the virtual equipment; (including invoking virtual appliance 1 … … to invoke virtual appliance n);
step 23: virtualizing the virtual device of step 22 into a logical device; (including virtualization logic device 1 … … virtualization logic device n);
step 24: sharing a virtual resource pool;
step 25: the virtual device queue is applied, and finally the actual physical device Microphone (MIC) is opened.
As shown in fig. 2, as a second embodiment of the present invention, the second embodiment is a further modification on the first embodiment,
in step S6, the device resource is locked exclusively, and finally the actual physical device camera is turned on.
In step 25, a virtual device queue is applied, and finally, the actual physical device camera is opened.
The invention has the beneficial effects that: according to the virtual equipment sharing method, as long as the virtual equipment is used, the equipment is firstly virtualized into the logic equipment, and the system can use the logic equipment as real equipment which is completely consistent with one physical equipment, so that one equipment can be accessed and used by multiple applications at the same time, multiple uses of one microphone equipment or video equipment are realized, and the product practicability and the use scene are effectively improved.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details.
