The plurality of applications may be, for example, at least one of the following applications: a network live video application, a video recording application, a camera application, and a video chat application.
The method for sharing the camera by multiple applications provided by the embodiment of the invention can also be applied to various different application scenes, for example, in a video conference scene, wherein at least one application program in the multiple application programs is a video chat application program and is used for carrying out video connection and sharing the acquired camera data to other video conference terminals, and at least one other application program is a video recording application program and is used for carrying out field recording and storing the acquired camera data; for another example, the method is used in an intelligent rearview mirror scene, wherein at least one application program is a camera application program, the reversing rearview function is realized based on the acquired camera data, and at least one other application program is a video recording application program, and is used for realizing driving video recording and storing the acquired camera data; for another example, in an object recognition scenario, among the plurality of applications, at least one application is a camera application for implementing object recognition, and at least one other application is a video recording application for performing live recording in a recognition process and storing acquired camera data.

In a specific embodiment, referring to fig. 2, the multiple application in-phase cameras may be implemented based on a system framework shared by the cameras, where when a first application requests to open a camera, a request for accessing the camera of the first application is received through an application program interface API of a camera application framework layer, and when the camera service detects that a camera abstract device object has not been created, the camera service accesses a camera driver, creates a new camera abstract device object, and completes a mapping relationship between the first application and the camera abstract device object; when another application program or application programs in the future request to access the camera again, the camera service establishes a mapping relation between the created camera abstract device object and the application program or application programs in the future, so that the application programs are mapped to the same camera abstract device object when accessing the camera, and the camera abstract device object corresponds to one camera hardware device.
In the method for sharing the camera by multiple applications provided by the embodiment of the invention, when multiple applications access the same camera, the same camera abstract device object can be provided for the multiple applications, so that different applications in a foreground running state share the same camera, different applications can acquire the camera data in time conveniently, the camera data can be shared, and the camera access efficiency of different applications can be improved.
In the method for sharing a camera by multiple applications provided in the embodiment of the present invention, in a process of sharing a camera by multiple applications, if a request for modifying a camera configuration of any application using the camera abstraction device object is received, the camera configuration information is modified in response to the request, and the modified camera configuration information is sent to the multiple applications from the camera abstraction device object.
In the embodiment of the present invention, if any application program in the multiple application programs requests modification of the camera configuration, the multiple application programs can acquire modified camera configuration information. For example, if a user needs to switch the resolution of the camera to obtain the video image to adjust the definition of the video image, the user may initiate a request for modifying the configuration information related to the resolution of the camera by interacting with any one of the plurality of application programs, and in a system in which the plurality of application programs operate, the configuration information of the camera hardware device is modified, so that the plurality of application programs can simultaneously obtain the video image of the camera after the resolution adjustment.
In the embodiment of the present invention, in a process of implementing sharing of a camera by multiple application programs, if a request for modifying camera configuration of any application program using the camera abstraction device object is received, the multiple application programs may further acquire modified camera configuration information by:
and in response to a request for modifying the camera configuration of any application program using the camera abstract device object, modifying the camera configuration information, and sending the modified camera configuration information to the camera abstract device object, so that any application program using the camera abstract device object acquires the modified camera configuration information from the camera abstract device object.
In the embodiment of the present invention, in the process of sharing a camera by multiple applications, if a request for acquiring camera data of any application using the camera abstraction device object is received, in response to the request, a corresponding camera data acquisition instruction is sent to a camera driver corresponding to the camera, and the acquired camera data is sent to the multiple applications from the camera abstraction device object.
In the embodiment of the invention, the multiple application programs can simultaneously acquire the same camera data by initiating the request for acquiring the camera data by any one of the multiple application programs, namely the multiple application programs only need to acquire the data once, so that the accuracy and the effectiveness of data acquisition are ensured, the occupation of system data resources in the camera data acquisition process can be reduced, the data transmission rate is higher, and the data carrying efficiency is improved.
In the embodiment of the present invention, in a process of implementing sharing of a camera by multiple application programs, if a request for acquiring camera data by any application program using the camera abstraction device object is received, the multiple application programs may further acquire the camera data by:
responding to a request for acquiring camera data by using any application program of the camera abstract device object, sending a corresponding camera data acquisition instruction to a camera driver corresponding to the camera, and sending the acquired camera data to the camera abstract device object, so that any application program using the camera abstract device object acquires the camera data from the camera abstract device object.
In the embodiment of the invention, in the process of realizing the camera sharing of a plurality of application programs, if a camera closing request of any application program in the plurality of application programs is received, responding to the request, and detecting whether the camera abstract equipment object is provided for at least one other application program for use;
if so, keeping the camera in a starting state;
and if not, sending a closing instruction to the camera, and deleting the abstract equipment object of the camera.
In the embodiment of the present invention, when any application program in the plurality of application programs needs to close the camera and stops acquiring data of the camera, a request may be initiated to close the camera, because there may be other application programs in the plurality of application programs that are using the camera, the camera cannot be directly closed, and only when it is determined that the application program that initiates the request is the last application program that uses the camera, a close instruction may be sent to the camera, the camera is closed, and the camera abstract device object corresponding to the camera is deleted.
In the embodiment of the present invention, the system may implement different camera access processes through different application program interfaces APIs of the camera application framework layer, which specifically includes:
when a plurality of application programs request to access the camera, the requests of the application programs for accessing the camera are received by opening the interface;
when any one of the plurality of application programs requests to modify the camera configuration, the request of the plurality of application programs for modifying the camera configuration is received through the stream configuration interface;
when any one of a plurality of application programs requests to acquire the camera data, the request of the plurality of application programs for acquiring the camera data is received through a stream request interface;
when any one of the plurality of application programs requests to close the camera, the request of the plurality of application programs for closing the camera is received through the closing interface.
In the embodiment of the present invention, based on the requests received by the opening interface, the stream configuration interface, the stream request interface, and the closing interface, the processes of opening the camera, modifying the camera configuration, acquiring the camera data, and finally closing the camera by the multiple application programs can be respectively implemented, and the specific implementation process may refer to the description in the above embodiment and will not be described herein again.
In a specific embodiment, the method for implementing foreground operation of multiple applications can be used to implement display of multiple applications on the same screen and in a foreground operation state, as shown in fig. 3, the specific implementation process includes:
s201: responding to starting requests of a plurality of application programs, and detecting whether the application programs have simultaneous operation labels;
s202: and for the detected target application program with the label, displaying the target application program and the foreground interface of at least one other application program in the plurality of application programs on the same screen, and keeping the target application program in a foreground running state.
It should be noted that, in the embodiment of the present invention, the plurality of application programs may include two or more application programs.
In the embodiment of the invention, for any application program with the simultaneously-running label, when the application program with the label is displayed on the same screen as other application programs, the target application program is always kept in the foreground running state, and whether the target application program acquires a focus in a window is not concerned, so that when the target application program with the simultaneously-running label and at least one other application program in a plurality of application programs are displayed on the same screen in different windows of a device screen, the target application program with the label is kept in the foreground running state on the foreground interface, and the purpose that a user interacts with at least two application programs displayed on the same screen in real time can be achieved.
The inventor of the present invention finds that, in a system in which a terminal device in the prior art operates, generally, only one application program can interact with a user in a foreground, and a foreground interface of the application program is in a foreground operating state at this time.
In addition, although the operating system (for example, the Android system) in the related art can realize the on-screen display of a plurality of applications, the system does not change the lifecycle of an Activity component (Activity) of each application in the multi-window mode, and therefore, in the multi-window mode, only the foreground interface of an application in a window that has interacted with a user recently is in an operating state. The foreground interfaces of the applications in the other windows are visible but are in a suspended state. When the foreground interface of the application program is in a pause state, the video is paused, the microphone stops recording, and the interface stops updating. This application may also be destroyed by the system when the system memory is too low.
In some special scenes, for example, when a network video live broadcast end device wants to start two or more network video live broadcast applications at the same time to perform synchronous video live broadcast on different network video live broadcast platforms, it is necessary that the recording, video recording, interfaces, and the like of the two or more network live broadcast applications are kept normal, and the technical scheme in the prior art cannot meet the requirements of the application scene.
Based on this, in the method for implementing foreground operation of multiple applications according to the embodiment of the present invention, by setting or adding the simultaneous operation tag to the application program, the application program with the simultaneous operation tag can be kept in the foreground operation state when other application programs are displayed on the same screen. Therefore, when two or more application programs with the simultaneously running tags are started, the sound recording, the video recording, the interfaces and the like of the two or more application programs are kept normal, and the two or more application programs can normally realize real-time interaction with the user, so that the requirements of the application scenes are met.
In this embodiment of the present invention, the start requests of the multiple application programs described in step S201 may be start requests sent by the multiple application programs in sequence, or start requests sent by the multiple application programs together.
The starting requests sent by the multiple application programs in sequence can be starting requests sent by the multiple application programs in sequence at different moments, and each application program is respectively allocated with one corresponding window when the multiple application programs are displayed on the same screen, so that if the multiple application programs send the starting requests in sequence, the windows can be reallocated once on the screen of the terminal equipment after the starting request of one application program is received, and the foreground interfaces of the application program sending the starting request later and the other application program or programs which are started are displayed on the same screen.
The starting request sent by the plurality of application programs together comprises the starting request sent by the plurality of application programs simultaneously in the process of one request, and each application program is respectively allocated with one corresponding window when the plurality of application programs are displayed on the same screen, so that the starting process can be started and executed sequentially according to a preset starting sequence if the plurality of application programs send the starting request together. Or the starting request sent by the multiple application programs together comprises the starting requests sent by the multiple application programs in sequence in the process of one request, and each application program is respectively allocated with one corresponding window when the multiple application programs are displayed on the same screen, so that if the multiple application programs send the starting requests together, each application program executes the starting action on the corresponding allocated window simultaneously.
In the embodiment of the present invention, the one-time request may be a start request that is sent by a plurality of applications simultaneously in response to a one-time start instruction initiated by a user or another application in a system of a terminal device.
In the embodiment of the present invention, the simultaneous operation tag of the application program may be obtained by at least one of the following methods:
presetting the label in an application program;
responding to a received starting request of the application program, and setting the label in a starting parameter of the corresponding application program;
and responding to the received request for adding the label, and setting the label in the corresponding application program.
In some embodiments, the simultaneous operation tag may be preset directly in the plurality of applications accessing the camera to obtain the application having the simultaneous operation tag, for example, before the application is downloaded to the terminal device, the provider of the application accessing the camera preset the simultaneous operation tag in the application to obtain a customized application, so as to run the customized application in the system of the terminal device.
In some embodiments, it may also be that the setting of the simultaneous run tag in the application accessing the camera is done by the system installing the application. For example, it may be that one or more applications that can set the simultaneous run tag are predetermined in the system. In the process of starting and running the application program, for the application program which is determined in advance and can access the camera, when a starting request of the application program is received, the system can add the simultaneous running label in the starting parameter of the application program which accesses the camera.
In some embodiments, it may also be that the user selects an application program accessing the camera, to which the simultaneous operation tag may be added, and if a request for adding the simultaneous operation tag is received, the simultaneous operation tag is set in the corresponding application program accessing the camera. For example, a selection box capable of selecting to add the simultaneous operation tag may be provided for the applications in the system setting interface, one or more applications capable of setting the simultaneous operation tag may be selected by the user during the interaction with the user, after the user selects a certain application or certain applications, a request for setting the simultaneous operation tag may be initiated, and the simultaneous operation tag may be added to the start parameter of the corresponding application by the system in response to the request for setting the simultaneous operation tag.
In this embodiment of the present invention, the plurality of application programs described in step S201 may each include an application program having a simultaneous operation tag. If the start request of the plurality of applications described in step S201 is a start request sent by a plurality of applications together, all the applications having the tag in the at least one other application may be in a foreground operating state.
In the embodiment of the present invention, the described target application may be any application in the plurality of applications. When a user initiates a start request sent by two or more application programs together, the two or more application programs can be started according to a preset start sequence for the two or more application programs, and the application program which is started last is enabled to acquire a focus and be in a foreground running state.
In the method for implementing foreground operation of multiple applications provided in the embodiment of the present invention, if a target application is a last started application, the application is in a foreground operation state due to the simultaneous operation tag, and a focus is obtained due to the last start of the target application; if the last started application is one of the at least one other application described in step S202, the last started application, no matter whether having the simultaneous operation tag or not, is in the foreground operation state due to the focus being acquired.
In a specific embodiment, the method for implementing foreground operation of multiple applications further includes:
and if the plurality of application foreground interfaces are displayed on the same screen, the application program which does not have the label acquires the focus, so that the application program acquiring the focus is in a foreground running state.
In the embodiment of the present invention, in the process of displaying the foreground interface on the same screen after the multiple applications are started, a user may interact with any application in the multiple applications, and the application interacting with the user will acquire a focus, so that, for an application not having the tag in the multiple applications, although the application is in a foreground pause state during starting, if the focus is acquired during the running process, the application not having the tag running at the same time that is acquired enters and maintains the foreground running state. Therefore, even if there is an application program that does not have the simultaneous operation tag among the applications for sharing the camera, the technical purpose of sharing the camera can be achieved by making the application program acquire the focus.
In a specific embodiment, if the start request of the multiple applications described in the step S201 is a start request sent by multiple applications together, the displaying the foreground interfaces of the target application and at least one other application in the multiple applications on the same screen described in the step S202 may specifically include:
and carrying out window allocation on the target application program and at least one other application program in the plurality of application programs according to a preset screen allocation format, and displaying foreground interfaces of the target application program and the at least one other application program on the same screen in the allocated window.
In a specific embodiment, the method for implementing foreground operation of multiple applications further includes:
in the process of displaying foreground interfaces of the plurality of application programs on the same screen, if a pause operation request for any application program is received, detecting whether the application program corresponding to the pause operation request comprises the label or not;
if so, keeping the application program corresponding to the pause operation request in a foreground running state;
if not, enabling the application program corresponding to the pause operation request to be in a foreground pause state.
In a specific embodiment, the pause operation request may be triggered by the following processes: and if the focus switching request is received, triggering a pause operation request of the application program losing the focus. For example, in the system running process, if a new operation request is received (for example, a user clicks the pop-up window interaction sub-interface according to the operation request of the pop-up window interaction sub-interface), a pause operation is executed for two or more application programs currently displayed on the same screen, and at this time, for the application programs with the simultaneously running tags, the foreground interface of the application program is kept in a foreground running state; if the application program does not have the simultaneous operation label and is in the foreground operation state, the foreground interface of the application program is changed into the foreground pause state because the application program loses focus; for an application that does not have the simultaneous run tag and is already in the foreground paused state, the foreground paused state is maintained.
Of course, in the system running process, the system may also automatically switch the focuses of two or more application programs displayed on the same screen, so that the application before switching loses the focus of the screen, and at this time, if the application before switching has the simultaneous running tag, the foreground running state is maintained; if the application does not have the simultaneous operation tag before the switching, the application program becomes a foreground temporary state in the on-screen display process because the application program loses focus.
The method for implementing foreground operation of multiple applications provided by the embodiment of the invention can be implemented based on a terminal device system in the prior art, wherein the terminal device system includes but is not limited to an Android system. The specific process for implementing the starting of the plurality of application programs may include:
if a user selects a plurality of application programs to be started, the plurality of application programs initiate starting requests to the system;
responding to the starting requests of the plurality of application programs, carrying out window allocation according to the screen size of the terminal equipment and a preset screen allocation format, allocating a window displayed by the foreground interface of each application program, and further displaying the foreground interface of each application program on the window allocated for the foreground interface.
In one embodiment, the allocation of windows may be achieved by:
when the application programs to be started are two application programs, a user can drag an icon of one application program to the upper side of an icon of the other application program by long-pressing the icon of the application program in the application starter, and then the two application programs can initiate starting requests.
In a specific embodiment, the allocation of windows may also be implemented by:
when the application programs are two or more than two application programs, if a user can press an icon of one application program in the application starter for a long time, the system interface enters a multi-selection mode, the user selects the two or more than two application programs, and then clicks a 'start' button, so that the selected application can initiate a start request.
According to the preset screen allocation scheme, when two or more application programs are started in an application starter mode, the application starter operates in a working mode of realizing Multi-application foreground operation (Multi-Run), and the screen allocation scheme is realized through the working mode, so that corresponding windows are allocated to a plurality of applications respectively. For example, when the number of the applications to be started is two, the screen of the terminal device may be divided into two windows in the height direction; when the number of the application programs to be started is three, the screen of the terminal equipment can be divided into three windows in the height direction; when the number of the applications to be started is two, the screen of the terminal device may be divided into four windows in the height direction, or the screen of the terminal device may be divided into four windows in a grid form.
Of course, in the embodiment of the present invention, the dividing manner of the window in the screen is not limited to the above-mentioned manner, and the dividing manner of the window in the screen may also be other manners provided in the prior art, and thus, the embodiment of the present invention may not be specifically limited.
In this embodiment of the present invention, referring to fig. 4 for each application program, it is assumed that the plurality of application programs include application programs 1 to N, where N is greater than or equal to 2, and a process of displaying a foreground interface of one application program in an allocated window is implemented specifically by:
an Activity Stack monitor (Activity Stack Supervisor) of the system firstly detects whether the application program has a simultaneous operation label;
if so, newly creating an Activity Stack (Activity Stack) of the application program through an Activity Display (Activity Display), and in the process of displaying the foreground interface of the application program, always setting the parameter value of an Activity Record (Activity Record) corresponding to an Activity component (Activity) at the topmost layer in the newly created Activity Stack as a parameter value for identifying that the application program is in a foreground running (On Resume) state, so that the application program keeps the foreground running state when the foreground interface of the application program and the foreground interfaces of other application programs are displayed On the same screen;
if not, newly creating an active stack of the application program through the active display, and only when a foreground interface of the application program acquires a focus in the display process of the foreground interface of the application program, updating a parameter value of an activity record corresponding to an active assembly at the topmost layer in the newly created active stack into a parameter value for identifying that the application program is in a foreground running state, so that the application program is in the foreground running state when the foreground interface of the application program and foreground interfaces of other application programs are displayed on the same screen; if the foreground interface of the application program loses focus, the parameter value of the activity record corresponding to the activity component at the topmost layer in the newly created activity stack is changed into a parameter value for identifying that the application program is in a foreground Pause (On Pause) state, and the application program is in the foreground Pause state.
In the embodiment of the invention, in order to control and realize the change of the foreground interface of each application program in the foreground running process of a plurality of application programs, the sequence of the opening of the active components of each application program is recorded in the Task stack Record (Task Record), and the sequence of the active components stored in the Task stack can be adjusted according to the stack pushing and popping operations of the active components, so that the foreground interface corresponding to which active component is displayed next when one active component is popped.
In a specific embodiment, in the method for implementing foreground operation of multiple applications, the size of the window corresponding to the application program may be adjusted or dragged according to an instruction sent by a user or a system, so as to meet the user requirements of the user on different application programs, and improve the user experience of the user. In the embodiment of the present invention, the size adjustment of the window corresponding to the foreground interface of the application program or the specific implementation process of the window dragging may refer to the description of the related technical solution in the prior art, as long as the size adjustment of the window or the window dragging can be implemented, which may not be specifically limited in the embodiment of the present invention.
In a specific embodiment, the method for implementing foreground operation of multiple applications further includes:
if a closing instruction of any application program or an application program foreground interface closing instruction is received, judging whether the application program which does not receive the closing instruction or the foreground interface closing instruction exists;
and if the current application program does not receive the closing instruction or the foreground interface closing instruction, enabling the application program which loses the focus at the latest to acquire the focus again.
In the embodiment of the invention, in the running process of the system, for two or more application programs displayed On the same screen, if an application program receives a closing instruction, the application program is switched from a foreground running state or a foreground pause state to a Stop (On Stop) state, then enters a Destroy (On Destroy) state, and finally closes the application program. At this time, the application launcher in the system may reallocate the screen display area for the foreground interface of the one or more application programs that have not been closed according to the number of the remaining one or more application programs and the preset screen allocation manner. And because the focus is switched when the application program receives the close instruction, the system records the last application program which acquires the focus when the focus is switched, and if the current application program is closed, whether the application program which loses the focus last exists is checked, so that the application program which loses the focus at the latest in other application programs which do not receive the close instruction or the foreground interface close instruction acquires the focus again.
In a specific embodiment, if the start requests of the multiple application programs described in step S201 are start requests sent by the multiple application programs in sequence, and at least one other application program described in step S202 includes an application program that does not have the tag, the method for implementing foreground operation of multiple applications may further include:
and if the starting request of the other application program without the label is earlier than the starting request of the target application program, enabling the other application program without the label to be in a foreground running state.
In the embodiment of the present invention, since the plurality of applications may include the application having the simultaneous operation tag or the application not having the simultaneous operation tag, for the plurality of applications, since the start request of the other application not having the simultaneous operation tag is earlier than the start request of the target application having the simultaneous operation tag, the other application not having the simultaneous operation tag enters the foreground operating state before the target application, and therefore, when the target application starts, the start request time can be kept earlier than the target application, and the other application not having the simultaneous operation tag keeps the foreground operating state, so that the start request time is earlier than the target application, and the other application not having the simultaneous operation tag can acquire the camera data even if the other application not having the simultaneous operation tag, and sharing of camera data is realized.
In a specific embodiment, if the start requests of the multiple application programs described in step S201 are start requests sequentially sent by the multiple application programs, and if the start requests respectively sent by the multiple application programs are sequentially received and the last started application program does not have the tag, the last started application program obtains the focus and is in the foreground operating state.
In the embodiment of the present invention, since the plurality of application programs may include an application program having a simultaneous operation tag or an application program not having the simultaneous operation tag, for other application programs not having the simultaneous operation tag, although the last started application program does not have the simultaneous operation tag, the last started application program finally acquires the focus, and therefore, the last started application program can keep a foreground operation state, so that the last started application program can realize sharing of camera data even if the last started application program acquires the camera data.
