Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As the functions of electronic devices are becoming more abundant, more electronic devices can implement more abundant functions through the mounted devices. For example, in a case where the electronic device is configured with a microphone, the electronic device may acquire audio data through the microphone, identify the acquired audio data, and then perform a corresponding operation according to an identification result. For example, when an acceleration sensor is installed in the electronic device, the electronic device may sense the acceleration magnitude or the acceleration direction of the electronic device through the acceleration sensor, so that different operations may be correspondingly adapted. For example, the electronic device may implement control of an operation target in an application program according to the acceleration. Further, in the case where the electronic apparatus is equipped with a proximity sensor, the electronic apparatus may control the electronic apparatus based on data detected by the proximity sensor. For example, turning off or turning on of the screen may be controlled.

Under the condition that a plurality of application programs in the electronic equipment can use the device, the electronic equipment can set corresponding device use permission for the device, and further the application program which acquires the device use permission corresponding to the device can use the device. For example, when the voice recognition application needs to acquire audio data collected by a microphone, it needs to acquire the device usage right corresponding to the microphone first. For another example, if the image capture application needs to use a flash lamp to perform light supplement during photographing, the device usage right of the flash lamp needs to be obtained first.

However, the inventor finds that after acquiring the device usage right and being preempted, the related application program tries to acquire the device usage right again in a polling manner until successfully acquiring the device usage right again, thereby causing a certain waste of resources. Specifically, in the process of reacquiring the device usage right, the application program consumes processor resources and system resources, but the device usage priority of the application program whose device usage right is preempted is generally lower than the device usage priority of the application program whose device usage right is preempted, so that even if the application program whose device usage right is preempted continuously tries to reacquire the device usage right, the device usage right cannot be actually acquired, and further the consumed processor resources and system resources are wasted.

Therefore, the inventor proposes an application control method, an application control apparatus, and an electronic device in the present application, where after an application requests to acquire a device usage right corresponding to a target device, an authorization occupation message is sent to the application when the device usage right is occupied by another application, so that if the application receives the authorization occupation message, the application stops acquiring the device usage right again. Therefore, the application program can not continuously consume system resources to request to obtain the device use permission under the condition that the device use permission is preempted by other application programs through the mode, and waste of the system resources is reduced.

The application environment to which the present application relates will be described first.

As shown in fig. 1, an application environment provided by this embodiment includes a hardware abstraction layer, a Framework layer, a system service, and an application program.

The Framework layer comprises a device management module and a data output module. The device management module is used for managing whether the application program can acquire the device use permission corresponding to the device, and determining which application program can acquire the device use permission corresponding to the device. The data output module is configured to specifically execute, under the control of the device management module, transmitting data (i.e., input streams included in the hardware abstraction layer in fig. 1) acquired by the device to the application program that obtains the device usage permission.

It should be noted that, in a case where there are a plurality of devices included in the electronic apparatus, the device management module and the data output module may be configured for each device. For example, if the device included in the electronic apparatus includes a microphone and a camera, the device management module and the data output module may be configured for the microphone, and the device management module and the data output module may be configured for the camera. For example, if the electronic device is an Android operating system, the device management module configured for the microphone may be an AudioPolicy module, and the data output module may be an AudioFlinger module. Then the input stream in the corresponding hardware abstraction layer may be an audio input stream.

The system service can be used as an information transmission medium between the device management module and the application program. The device management module and the system service can transmit information in an interprocess communication mode. For example, interprocess communication may be performed by way of a socket. If the device management module needs to notify the application program that the device usage right is occupied by the specific application program at present, a notification message may be sent to the system service, so that the system service may broadcast the application program that has occupied the device usage right to other application programs by sending a broadcast message after receiving the notification message. The implementation of system services may vary in different operating systems. For example, if the electronic device is an Android operating system, the system Service may be a Service built based on a Service component.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 2, an application control method provided by the present application is applied to an application, and the method includes:

s110: and requesting to acquire the device use permission corresponding to the target device by the application program, wherein the application program acquiring the device use permission allows the target device to be used.

After the application program obtains the device usage right corresponding to the device to be used, the electronic device where the application program is located will allow the application program to use the target device. The application program using the target device may include the application program using a function provided by the target device or may include the application program acquiring data collected by the target device. For example, if the target device is a flash lamp, the application program may call the flash lamp to start within a required time after acquiring the device usage right corresponding to the flash lamp. For another example, if the target device is a microphone, the application program may be allowed to acquire the audio data collected by the microphone after acquiring the device usage right corresponding to the microphone. For another example, if the target device is a camera, the application program may be allowed to acquire the image data acquired by the camera after acquiring the device usage right corresponding to the camera.

Wherein the target device is a device requested to be used by the application program. For example, if the application functions as voice recognition, the device requested to be used by the application functioning as voice recognition may be a microphone. For another example, if the application functions as a flashlight, then the device requested for use by the application that functions as a flashlight may be a flashlight. For another example, if the application functions as image capture, the devices requested to be used by the application functioning as image capture may be a microphone and a camera.

In the embodiment of the application, the application program can request to acquire the device usage right of the target device under various conditions.

As one mode, after acquiring the device usage right, the application may request to acquire the device usage right corresponding to the target device under the condition that the acquired device usage right is occupied. It should be noted that, in the electronic device, the priority of use of different applications may be different for the same device. For example, in the Android system, the usage priority corresponding to the microphone may include a priority based on a HOTWORD type and a priority based on a non-HOTWORD type. Wherein the priority based on the HOTWORD type is lowest.

The application program with higher use priority can more easily acquire the device use right. The electronic device may compare the usage priority of the application program that sends the request with the usage priority of the application program that already occupies the device usage right when the device usage right that the application program requests to acquire a certain device is acquired, and if the usage priority of the application program that already occupies the device usage right is lower than the usage priority of the application program that sends the request, the electronic device may transfer the device usage right to the application program that sends the request.

For example, for a microphone, the priority of use of a voice recognition application is lower than the priority of use of a voice call application (e.g., an application that can engage in a bluetooth voice call). If the electronic device obtains a request for using the microphone from the voice call application program, the device usage right of the microphone is transferred to the voice call application program if the voice recognition application program already possesses the device usage right of the microphone. Then, for the voice recognition application program, under the condition that the device usage right of the microphone that the voice recognition application program has already acquired is preempted by the voice call application program, the voice recognition application program may request to acquire the device usage right corresponding to the target device in a polling manner.

Alternatively, the application may request to acquire the device usage rights of the target device while in the running state. When the application program detects that the application program is started, the application program can determine that the application program is in a running state. For example, for some electronic devices having speech recognition functionality, the speech recognition functionality may be implemented by a speech recognition application installed in the electronic device. After the electronic device is started, the voice recognition application installed in the electronic device can be started synchronously, and the started voice recognition application can make a request for the device use permission of the microphone.

As another way, the application program may start to request to acquire the device usage right corresponding to the target device after displaying the designated function interface. For example, applications lower than some instant messaging applications may also have a code scanning payment function, and for such applications, the acquisition of the device usage right corresponding to the target device (e.g., a camera) may also be requested when the code scanning interface is displayed.

S120: and if the application program receives the permission occupation message, the application program stops requesting to acquire the device use permission, the permission occupation message is used for informing the application program, and the device use permission is occupied by other application programs.

The application program may perform acquisition in a polling manner in the process of requesting acquisition of the device usage right of the target device, and then, after detecting that acquisition of the device usage right fails, the application program may perform the device usage right request again at intervals of a specified time until the device usage right of the target device is acquired. However, the application needs to consume processor resources as well as system resources (e.g., memory resources) in initiating the request. In order to avoid the waste of the processor resources and the system resources by the application program, the system service in the electronic device may send the permission occupation message to the application program, so that the application program is in an idle state after receiving the permission occupation message, and further stops requesting to acquire the device usage permission. Correspondingly, as a mode, if the application receives the permission occupation message, the application stops requesting to acquire the device usage permission, including: and if the application program receives the permission occupation message sent by the system service, the application program stops requesting to acquire the device use permission.

It should be noted that, after the application stops requesting to obtain the device usage right of the target device, in order to enable the application to immediately resume using the target device, in this embodiment, the electronic device may further notify the application by sending a right occupation message. As a mode, after the application stops requesting to acquire the device usage right if the application receives the right occupation message, the method further includes: and if the application program receives the permission release message, recovering the request to acquire the device use permission, wherein the permission release message is used for informing the application program that the device use permission is in an idle state.

The permission release message can enable the application program to timely recover the request to acquire the device use permission of the target device after stopping acquiring the device use permission of the target device, and further the application program can be favorably used for quickly acquiring the device use permission of the target device. For example, as shown in fig. 3, assuming that the application may request to acquire the device usage right of the target device once every time duration n after time t starts, if a certain request fails, the application needs to wait for the time duration n before making the next request. For example, if the application fails to request at time t + n, the next request is made only when time t +2n is obtained, but the application occupying the device usage right of the target device may release the device usage right of the target device between time t + n and time t +2n, and therefore the application originally requesting to obtain the device usage right cannot use the target device in a timely manner. By the method provided by the embodiment, the application program which is in the idle state and stops obtaining the device use permission can immediately recover the request for obtaining the device use permission after receiving the permission release message. For example, if the application receives the permission release message at a time between t + n and t +2n, the application may immediately recover the request to acquire the device usage permission after receiving the permission release message.

One way, the target device includes a microphone, and the data collected by the target device includes audio data collected by the microphone.

In the application control method provided in this embodiment, after an application requests to acquire a device usage right corresponding to a target device, a right occupation message is sent to the application under the condition that the device usage right is occupied by other applications, so that if the application receives the right occupation message, the application stops reacquiring the device usage right. Therefore, the application program can not continuously consume system resources to request to obtain the device use permission under the condition that the device use permission is preempted by other application programs through the mode, and waste of the system resources is reduced.

Referring to fig. 4, an application control method provided by the present application is applied to a system service, and the method includes:

s210: if the first application program acquires the device use permission corresponding to the target device and acquires a request of a second application program for acquiring the device use permission, a permission occupation message is sent to the second application program so that the second application program stops acquiring the device use permission, and the second application program is the application program requesting to acquire the device use permission. And the permission occupation message is used for informing the second application program that the device use permission is occupied by other application programs.

In embodiments of the present application, sending a message to an application may be accomplished by a system service.

As one way, the system service may be determined according to the occupation condition and the request condition of the acquired device usage right of the device. In this way, the device management module corresponding to each device can obtain the device permission occupation condition and the request condition synchronously, so that the system service can also obtain the current device permission occupation condition and the request condition synchronously, and the permission occupation message is determined when to be sent according to the obtained current device permission occupation condition and the obtained request condition.

Illustratively, as shown in fig. 5, the device management module includes a device management module 1, a device management module 2, and a device management module 3. The device management module 1 is configured to manage the device usage right of the device 1, and the device management module 1 may synchronize the occupation and request of the device usage right of the device 1 with the system service. The device management module 2 is configured to manage the device usage right of the device 2, and the device management module 2 may synchronize the occupation situation and the request situation of the device usage right of the device 2 with the system service. The device management module 3 is configured to manage the device usage right of the device 3, and the device management module 3 may synchronize the occupation situation and the request situation of the device usage right of the device 3 with the system service.

The system service, upon receiving the occupation status and the request status sent by each device management module, may generate the contents in the data table style shown in fig. 4. The current occupant and the requester corresponding to each device may be recorded in the data table. And the current occupant is an application program of the device use authority corresponding to the current occupied device. The requester is an application program which sends a device use permission request for occupying the device but does not successfully acquire the device use permission after the current occupant corresponding to the device is determined. Furthermore, there may be more than one requestor corresponding to the device, for example, in fig. 5, the requestor corresponding to the device 1 may have the application 2 and the application 4, which means that during the period when the current occupant of the device 1 is updated to the application 1, both the application 2 and the application 4 have sent a request for requesting the device usage right of the device 1, but neither has successfully acquired the device usage right of the device 1. Optionally, after the current occupant corresponding to the device is updated, the requester corresponding to the device may be updated synchronously.

Furthermore, as another way, the system service may determine at what timing the right occupation message is transmitted specifically according to the instruction of the device management module. In this manner, the device management module may not synchronize the request and occupation of the device usage rights with the system service, but may send a notification message directly, where the notification message may be determined by the system service as a trigger instruction. For example, if the device management module 1 desires the system service to broadcast a message, and the content of the message is that the device usage right of the device 1 is already occupied by the application program 1, the device management module 1 may send a notification message to the system service, and the system service may respond to the notification message to broadcast a right occupation message, the content of which is that the device usage right of the device 1 is already occupied by the application program 1, so that other application programs that desire to acquire the device usage right of the device 1 may stop requesting.

It should be noted that, as described in the foregoing, the permission occupation message may be triggered by the system service according to the occupation situation and the request situation, or may be triggered according to the notification message sent by the device management module. While for the two aforementioned approaches, the occupancy for the resources may be different. For example, if the system service is triggered according to the occupation situation and the request situation, because the number of determination steps required by the system service increases, the resources (processor resources and memory resources) occupied by the system service are more, but in the electronic device, the resources possibly allocated to each module are limited, and if the resources required by the module are close to or exceed the resources allocated by the electronic device, the operation of the module may be locked, which may cause the whole electronic device to be locked. Then, in order to reduce the probability of the electronic device being stuck, the system service may determine, according to the resource occupied by itself, which manner is specifically adopted to trigger sending the permission occupation message to the application program.

Optionally, the system service may compare the occupied resources with the resources allocated to the electronic device, and if a difference between the occupied resources and the allocated resources meets a threshold condition, the system service determines that the permission occupation message is triggered by the system service according to an occupation situation and a request situation of the device management permission sent by the device management module. Optionally, if the system service determines that the difference between the occupied resource and the allocated resource does not satisfy the threshold condition, the system service may determine when the device management module determines to send the right occupation message.

After determining the trigger mode of the permission occupation message, the system service may send a message to the device management module, where the sent message carries the currently determined trigger mode, so that the device management module may determine the content sent to the system service according to the trigger mode carried in the message. For example, if the system service triggers the permission occupation message according to the occupation condition and the request condition of the device management permission sent by the device management module in the message sent by the system service to the device management module, the device management module may start synchronizing the occupation condition and the request condition of the device usage permission to the system service. If the trigger mode carried in the message sent by the received system service to the device management module is that the device management module determines the sending time of the permission occupation message, the device management module stops synchronizing the occupation condition and the request condition of the device usage permission to the system service, and sends a notification message to the system service when determining that the permission occupation message needs to be sent.

The threshold condition represents that the resources occupied by the system service do not influence the normal operation of the system service. Optionally, the threshold condition may include that a difference between the occupied resource and the allocated resource is below a specified threshold. When the types of the resources are various, a specified threshold may be corresponding to each type of resource, and it is determined that the threshold condition is satisfied when the difference corresponding to each type of resource satisfies the specified threshold corresponding to the type of resource.

For example, the resources involved in the threshold condition may include processor resources and memory resources, then a specified threshold may be corresponding to the processor resources, and a specified threshold may be corresponding to the memory resources, and further, it may be determined that the threshold condition is satisfied under the condition that it is determined that a difference between the occupied processor resources and the allocated processor resources is smaller than the specified threshold corresponding to the processor resources, and that a difference between the occupied memory resources and the allocated memory resources is smaller than the specified threshold corresponding to the memory resources. Correspondingly, the threshold condition is determined not to be satisfied under the condition that the difference value between the occupied processor resource and the allocated processor resource is not smaller than the designated threshold corresponding to the processor resource, or the difference value between the occupied memory resource and the allocated memory resource is not smaller than the designated threshold corresponding to the memory resource.

The system service can determine the triggering mode of the permission occupation message and the permission release message according to whether the ratio of the occupied resources to the allocated resources meets the threshold condition, so that the flexibility of triggering the permission occupation message and the permission release message is improved, and the electronic equipment is prevented from being stuck due to the fact that extra judgment logic (namely, the logic for triggering the permission occupation message and the permission release message according to the occupation condition and the request condition of the device use permission) is added in the system service.

Furthermore, in order to facilitate the application program requesting to acquire the device usage right to know what operation the application program currently acquiring the device usage right is actually performing, as a way, the sending the right occupation message to the second application program includes: and sending an authority occupation message carrying the identifier of the first application program and the operation of the first application program to the second application program, wherein the operation is the operation of occupying the device use authority by the first application program. The identifier of the application may be a PID (Process ID) or a packet name of the application.

As a manner, after the first application program acquires the device usage right corresponding to the target device and acquires a request of the second application program to acquire the device usage right, and sends a right occupation message to the second application program, the method further includes: if the first application program releases the device use permission corresponding to the target device, sending a permission release message to the second application program so as to be used for the second application program to recover and request to acquire the device use permission; the permission release message is used for informing the application program that the device use permission is in an idle state.

It should be noted that, in this embodiment, there are various sending manners for the permission occupied message, and after the manner of sending the permission occupied message is specifically determined, the manner of correspondingly sending the permission release message is the same as the determined manner of sending the permission occupied message.

For example, if it is determined that the system service triggers the permission occupation message according to the occupation situation and the request situation sent by the device management module, the permission release message is triggered based on the occupation situation and the request situation sent by the device management module if the permission release message needs to be sent. For another example, if it is determined that the permission taken message is triggered by the device management module sending a notification message to the system service, the permission release message is also triggered by the device management module sending a notification message to the system service. It is understood that the content of the notification message triggering the system service to send the permission occupation message and the content of the notification message triggering the system service to send the permission release message may be different.

As one way, after the second application stops obtaining the device usage right of the target device, the requesting device usage right may be recovered in other ways besides by receiving the right release message. It should be noted that, in general, the application program will acquire the device usage right of the target device only when the application program is in a running state. For example, the voice call application program is in an operating state, and then obtains the device usage right of the microphone. Then the device usage rights of the device are not taken up again when the application exits the running state (e.g., the main process of the application is closed). Moreover, after the device usage right acquired by the application program is occupied, the application program whose device usage right is preempted may be switched to be in background operation. For example, as shown in fig. 6. An interface 10 of a speech recognition application is shown in the left image of fig. 6 by way of example, and in the case of the smart watch display interface 10 shown in fig. 6, the speech recognition application is currently authorized to acquire device usage rights to the microphone. When the smart watch detects an incoming call, the voice call application is started, so that the smart watch is switched to display the incoming call interface 20 shown in the right image in fig. 6. Under the condition that the smart watch displays the incoming call interface 20, the voice communication application program already acquires the device use permission of the microphone, the voice recognition application program with the device use permission of the microphone preempted is switched to background operation, or the interface of the voice recognition application program is covered by the incoming call interface of the voice communication application program.

In this manner, the application that stops requesting the device usage right in response to the right occupation message may determine whether to resume the device usage right of the request target device according to whether the application is switched to the foreground for operation or whether the interface of another application covers the interface of the application. Optionally, if the application program requesting the device usage permission is stopped in response to the permission occupation message and it is detected that the application program is switched to be in the foreground for operation, it may be determined that the application program preempting the device usage permission has exited from the foreground for operation, and then the device usage permission of the target device may be requested to be acquired. Optionally, if the application program requesting the device usage right is stopped in response to the right occupation message, and it is detected that no interface of another application program is covered on the interface of the application program, it may be determined that the application program preempting the device usage right has exited running, and then the device usage right of the target device may be requested to be obtained.

It should be noted that, in the case that the application program can determine the recovery requesting device usage right in various ways, the application program may also determine which way to specifically recover the requesting device usage right according to its own situation. As one way, the application may recover the usage right of the requesting device according to the right reply message when determining that the application does not include the user operation interface (e.g., the interface 10 shown in fig. 6), and correspondingly, may recover the usage right of the requesting device when determining that the application includes the user operation interface and detecting that the application is in foreground operation or no interface of another application is overlaid on the interface of the application.

In the application control method provided in this embodiment, after a first application requests to acquire a device usage right corresponding to a target device, and under a condition that the device usage right is occupied by a second application, a right occupation message is sent to the second application, so that if the first application receives the right occupation message, the device usage right is stopped being acquired again. Therefore, by the method, the first application program does not continuously consume system resources and requests to acquire the device use permission under the condition that the acquired device use permission is occupied by the second application program after the device use permission is acquired originally, and waste of the system resources is reduced.

s310: after a first application program obtains the device use permission of a target device, if a request for obtaining the device use permission of the target device sent by a second application program is received, a permission occupation message is sent to the second application program so that the second application program stops obtaining the device use permission, and the second application program is the application program requesting to obtain the device use permission;

and the permission occupation message is used for informing the second application program that the device use permission is occupied by other application programs.

It should be noted that the device management module is a module for managing device usage rights of the corresponding device. Before the application program needs to use the target device, a request for acquiring the device usage permission corresponding to the target device may be sent to the device management module, then the device management module may compare the usage priority of the application program that sends the request with the usage priority of the application program that has currently acquired the target device after receiving the request sent by the application program, and if the usage priority of the application program that sends the request is not higher than the usage priority of the currently acquired target device, then the device management module may reject the request and continue to maintain the device usage permission of the application program that has currently acquired the target device.

As one mode, the sending the permission taken message to the second application includes:

and sending a notification message to a system service, wherein the notification message is used for triggering the system service to send the permission occupation message to the first application program.
