[0002] As electronic devices support more and more functions, they are equipped with various components, such as microphones and cameras. When an application in an electronic device needs to access data collected by these components, it must first obtain permission to use the corresponding component.

[0008] Fifthly, this application provides an application control device running on a system service.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0027] As electronic devices become increasingly feature-rich, they can achieve more advanced functions through installed components. For example, an electronic device equipped with a microphone can acquire and process audio data, then perform corresponding actions based on the recognition results. Similarly, an electronic device with an accelerometer can sense its own acceleration magnitude and direction, allowing for tailored operations. For instance, an electronic device can use acceleration to control operations within an application. Furthermore, an electronic device with a proximity sensor can control itself based on the data detected by the sensor. For example, it can control whether the screen is on or off.
[0028] When multiple applications can use a device within an electronic device, the device can assign specific usage permissions to that device, allowing only applications with the appropriate permissions to use it. For example, a voice recognition application needs to obtain microphone access permissions to access audio data collected by a microphone. Similarly, an image capture application needs flash access permissions to use the flash for supplemental lighting in a photo.
[0029] However, the inventors discovered that when related applications have already acquired device usage rights but are then preempted, they will attempt to reacquire those rights using a polling method until they successfully regain them, resulting in resource waste. Specifically, during the process of reacquiring device usage rights, applications consume processor and system resources. However, the device usage priority of the application whose rights were preempted is generally lower than that of the application that preempted the rights. Therefore, even if the application whose rights were preempted repeatedly attempts to reacquire them, it is actually unable to obtain the necessary permissions, thus wasting the processor and system resources consumed.
[0030] Therefore, the inventors have proposed an application control method, apparatus, and electronic device as described in this application. After an application requests device usage rights for a target device, if those rights are already occupied by another application, the method sends a permission occupation message to the application. Upon receiving this message, the application stops attempting to re-acquire device usage rights. This prevents the application from continuously consuming system resources to request device usage rights when they are already occupied by another application, thus reducing waste of system resources.
[0031] The application environment involved in this application will be introduced below.
[0032] like Figure 1 As shown, the application environment provided in this embodiment includes a hardware abstraction layer, a framework layer, system services, and applications.
[0033] The Framework layer includes a device management module and a data output module. The device management module manages whether applications can obtain device usage permissions and determines which specific application can obtain these permissions. The data output module, under the control of the device management module, executes the actual execution of data collection from the device (i.e.,...) Figure 1 The input stream (including the hardware abstraction layer) is transmitted to the application that has obtained the device's usage rights.
[0034] It should be noted that when an electronic device includes multiple components, the component management module and data output module can be configured separately for each component. For example, if the electronic device includes a microphone and a camera, then separate component management and data output modules can be configured for the microphone and the camera, respectively. For instance, if the electronic device runs on the Android operating system, the component management module for the microphone could be the AudioPolicy module, and the data output module could be the AudioFlinger module. The corresponding input stream in the hardware abstraction layer would then be an audio input stream.
[0035] System services serve as a medium for information transmission between the device management module and applications. Information can be transmitted between the device management module and system services via inter-process communication (IPC), such as through sockets. If the device management module needs to notify an application which application currently holds device usage rights, it can send a notification message to the system service. Upon receiving this message, the system service can then broadcast the application holding device usage rights to other applications via a broadcast message. The implementation of system services can differ across operating systems. For example, if the electronic device uses the Android operating system, the system service can be a service built upon the Service component.
[0036] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0037] Please see Figure 2 This application provides an application control method, applied to an application, the method comprising:
[0038] S110: The application requests to obtain device usage permission corresponding to the target device, wherein the application that obtains the device usage permission is allowed to use the target device.
[0039] In this process, an application will only be allowed to use a target device after obtaining the necessary device usage permissions from the electronic device on which the application resides. The application's use of the target device can include utilizing the device's functions or acquiring data collected by the device. For example, if the target device is a flash, the application, after obtaining the necessary device usage permissions, can activate the flash at the required time. Similarly, if the target device is a microphone, the application, after obtaining the necessary device usage permissions, can acquire the audio data collected by the microphone. And if the target device is a camera, the application, after obtaining the necessary device usage permissions, can acquire the image data collected by the camera.
[0040] The target device refers to the device requested by the application. For example, if the application's function is voice recognition, then the device requested by the application for voice recognition could be a microphone. As another example, if the application's function is a flashlight, then the device requested by the application for a flashlight could be a flashlight. Yet another example, if the application's function is image acquisition, then the device requested by the application for image acquisition could be a microphone and a camera.
[0041] In this application embodiment, the application can request and obtain device usage rights for the target device under various circumstances.
[0042] As one approach, an application can request additional device usage permissions for a target device if those permissions are already in use. It's important to note that in electronic devices, different applications may have different usage priorities for the same device. For example, in the Android system, the microphone's usage priority can include both HOTWORD-based and non-HOTWORD-based priorities. HOTWORD-based priorities have the lowest priority.
[0043] Applications with higher usage priority are more likely to obtain device usage rights. When an electronic device receives a request from an application to use a device, it compares the usage priority of the requesting application with that of an application that already holds the device usage rights. If the usage priority of the application that already holds the device usage rights is lower than that of the requesting application, the electronic device will transfer the device usage rights to the requesting application.
[0044] For example, when it comes to microphones, voice recognition applications have lower usage priority than voice call applications (e.g., applications that can make Bluetooth voice calls). So, if a voice recognition application already has device access to the microphone, and the electronic device receives a request from a voice call application to use the microphone, it will transfer the microphone's device access to the voice call application. Conversely, if a voice recognition application's previously acquired microphone access has been preempted by the voice call application, the voice recognition application can request device access to the target device through a polling process.
[0045] As another approach, an application can request device access permissions for a target device while it is running. Specifically, an application can determine it is running once it detects that it has been launched. For example, some electronic devices have voice recognition capabilities, which can be implemented through a voice recognition application installed on the device. When the electronic device starts up, the installed voice recognition application can start simultaneously, and then request device access permissions for the microphone.
[0046] As another approach, the application can request device usage permissions for the target device after displaying the specified function interface. For example, some instant messaging applications also have QR code payment functionality; for such applications, they can request device usage permissions for the target device (e.g., a camera) when displaying the QR code scanning interface.
[0047] S120: If the application receives a permission occupancy message, the application stops requesting to obtain the device usage permission. The permission occupancy message is used to notify the application that the device usage permission has been occupied by another application.
[0048] In this process, the application can use a polling method to request device usage rights for a target device. If the application fails to obtain device usage rights, it will re-request the rights after a specified interval until it obtains them. However, initiating these requests consumes processor and system resources (e.g., memory). To avoid wasting processor and system resources, the system service in the electronic device can send a permission occupancy message to the application. Upon receiving this message, the application will become idle and stop requesting device usage rights. Correspondingly, as one approach, if the application receives a permission occupancy message, the application stops requesting device usage rights, including: if the application receives a permission occupancy message from the system service, the application stops requesting device usage rights.
[0049] It should be noted that, after the application stops requesting device usage rights for the target device, in order for the application to immediately resume using the target device, in this embodiment, the electronic device can also notify the application by sending a permission occupancy message. As one approach, if the application receives a permission occupancy message and stops requesting device usage rights, the method further includes: if the application receives a permission release message and resumes requesting device usage rights, the permission release message is used to notify the application that the device usage rights are in an idle state.
[0050] Specifically, the permission release message allows the application to promptly resume requesting device usage permissions after it has stopped acquiring them, thus facilitating the application's rapid use of the target device. For example, ... Figure 3As shown, assuming an application can request device usage rights for a target device every n intervals starting from time t, if a request fails, the application needs to wait n hours before making the next request. For example, if the application fails to request at time t+n, it will wait until time t+2n to make the next request. However, the application that has been holding device usage rights for the target device may have already released those rights between t+n and t+2n. Therefore, the application that originally obtained device usage rights cannot use the target device in a timely manner. The method provided in this embodiment allows an application that is idle and has stopped acquiring device usage rights to immediately resume requesting device usage rights upon receiving a permission release message. For example, if the application receives a permission release message at some point between t+n and t+2n, it can immediately resume requesting device usage rights upon receiving the message.
[0051] In one embodiment, the target device includes a microphone, and the data acquired by the target device includes audio data acquired by the microphone.
[0052] This embodiment provides an application control method that, after an application requests device usage rights for a target device, if those rights are already occupied by another application, sends a permission occupation message to the application. Upon receiving this message, the application stops attempting to re-acquire device usage rights. This method prevents the application from continuously consuming system resources to request device usage rights when they are already held by another application, thus reducing waste of system resources.
[0053] Please see Figure 4 This application provides an application control method for system services, the method comprising:
[0054] S210: If the first application obtains device usage rights corresponding to the target device, and receives a request from the second application to obtain the device usage rights, a permission occupancy message is sent to the second application to cause the second application to stop obtaining the device usage rights. The second application is the application that requested the device usage rights. The permission occupancy message is used to notify the second application that the device usage rights are occupied by another application.
[0055] In this embodiment of the application, the sending of messages to the application can be accomplished by a system service.
[0056] In one approach, the system service can determine the appropriate usage information based on the device's permission status and request status. In this method, the device management module for each device can synchronize the device permission status and request status to the system service, allowing the system service to also synchronously obtain the current device permission status and request status. Based on this information, the system service can then determine when to send a permission usage message.
[0057] For example, such as Figure 5 As shown, the system includes three modules: Module 1, Module 2, and Module 3. Module 1 manages the usage permissions of Device 1, and can synchronize the usage permission status and request information of Device 1 with the system service. Module 2 manages the usage permissions of Device 2, and can synchronize the usage permission status and request information of Device 2 with the system service. Module 3 manages the usage permissions of Device 3, and can synchronize the usage permission status and request information of Device 3 with the system service.
[0058] After receiving the occupancy status and request information from each device management module, the system service can generate... Figure 4 The data table shown contains the following information. This data table can record the current occupant and requester for each device. The current occupant is the application that currently occupies the device and has the corresponding device usage rights. The requester is any application that, after the current occupant is determined, sent a device usage rights request but failed to obtain the rights. Furthermore, there can be more than one requester for a device; for example, in... Figure 5 The requesters corresponding to device 1 can be application 2 and application 4. This indicates that during the period when the current occupant of device 1 was updated to application 1, both application 2 and application 4 sent requests for device usage rights to device 1, but neither successfully obtained device usage rights. Optionally, after the current occupant of the device is updated, the requesters corresponding to the device can be updated synchronously.
[0059] Furthermore, as another approach, the system service can determine the specific timing for sending a permission occupancy message based on instructions from the device management module. In this method, the device management module doesn't need to synchronize device usage permission request and occupancy status with the system service; instead, it can directly send a notification message, which the system service can interpret as a triggering instruction. For example, if device management module 1 wants the system service to broadcast a message stating that device usage permission for device 1 has been occupied by application 1, device management module 1 can send a notification message to the system service. The system service can then respond to this notification message by broadcasting a permission occupancy message indicating that device usage permission for device 1 has been occupied by application 1, thereby preventing other applications requesting device usage permission for device 1 from making their requests.
[0060] It should be noted that, as described above, permission occupancy messages can be triggered by system services based on occupancy and request status, or by notification messages sent by the device management module. The resource consumption of these two methods can differ. For example, if triggered by system services based on occupancy and request status, the increased decision-making steps required by the system service will result in higher resource consumption (processor and memory resources). However, in electronic devices, the resources allocated to each module are likely limited. If a module's resource requirements approach or exceed the allocated resources, the module's performance may lag, causing overall lag in the electronic device. Therefore, to reduce the probability of lag in electronic devices, the system service can determine which method to use to trigger the permission occupancy message sent to the application based on its own resource consumption.
[0061] Optionally, the system service can compare the occupied resources with the resources allocated to the electronic device. If the difference between the occupied and allocated resources meets a threshold condition, the system service determines to trigger a permission occupancy message based on the device management permission occupancy and request status sent by the device management module. Optionally, if the system service determines that the difference between the occupied and allocated resources does not meet the threshold condition, the system service can determine that the device management module determines the specific timing for sending the permission occupancy message.
[0062] After determining the triggering method for the permission occupancy message, the system service can send a message to the device management module. This message carries the determined triggering method, allowing the device management module to determine the content to send to the system service based on this information. For example, if the system service's message to the device management module indicates that the permission occupancy message is triggered by the system service based on the device management module's information regarding permission occupancy and requests, then the device management module will begin synchronizing the device usage permission occupancy and request information with the system service. Conversely, if the received message from the system service indicates that the device management module itself determines when to send the permission occupancy message, then the device management module will stop synchronizing the device usage permission occupancy and request information with the system service and will instead send a notification message to the system service when it determines that a permission occupancy message needs to be sent.
[0063] The threshold condition indicates that the resources occupied by the system service will not affect the normal operation of the system service. Optionally, the threshold condition may include the difference between the occupied resources and the allocated resources being lower than a specified threshold. Where there are multiple types of resources, a specified threshold may be assigned to each type of resource, and the threshold condition is determined to be met if the difference for each type of resource satisfies the specified threshold for that type of resource.
[0064] For example, the resources involved in the threshold condition may include processor resources and memory resources. There may be a specified threshold for processor resources and a specified threshold for memory resources. Therefore, if the difference between the occupied processor resources and the allocated processor resources is less than the specified threshold for processor resources, and the difference between the occupied memory resources and the allocated memory resources is less than the specified threshold for memory resources, then the threshold condition is determined to be met. Conversely, if the difference between the occupied processor resources and the allocated processor resources is not less than the specified threshold for processor resources, or the difference between the occupied memory resources and the allocated memory resources is not less than the specified threshold for memory resources, then the threshold condition is determined not to be met.
[0065] Because the system service can determine the triggering method of permission occupation messages and permission release messages by whether the ratio of occupied resources to allocated resources meets the threshold condition mentioned above, the triggering of permission occupation messages and permission release messages is improved. At the same time, it is also helpful to avoid electronic device lag caused by adding extra judgment logic in the system service (i.e., the logic of triggering permission occupation messages and permission release messages based on the occupation and request status of device usage permissions).
[0066] Furthermore, to facilitate applications requesting device usage permissions to understand what operation they are actually performing once they have acquired device usage permissions, as a method, sending a permission occupancy message to the second application includes: sending a permission occupancy message to the second application carrying the identifier of the first application and the operation of the first application, wherein the operation is the first application occupies the device usage permissions. The application identifier can be a PID (Process ID) or the application's package name.
[0067] As one approach, if the first application obtains device usage permission corresponding to the target device and receives a request from the second application to obtain the device usage permission, after sending a permission occupation message to the second application, the method further includes: if the first application releases the device usage permission corresponding to the target device, sending a permission release message to the second application, so that the second application can resume requesting to obtain the device usage permission; the permission release message is used to notify the application that the device usage permission is in an idle state.
[0068] It should be noted that in this embodiment, there may be multiple ways to send the permission occupation message. After the specific method of sending the permission occupation message is determined, the method of sending the corresponding permission release message is the same as the method of sending the determined permission occupation message.
[0069] For example, if the system service triggers the permission occupancy message based on the occupancy and request information sent by the device management module, then the permission release message will also be triggered based on the same occupancy and request information sent by the device management module. As another example, if the device management module sends a notification message to the system service to trigger the permission occupancy message, then the permission release message will also be triggered by the device management module sending a notification message to the system service. It's important to understand that the content of the notification message that triggers the system service to send the permission occupancy message will differ from the content of the notification message that triggers the system service to send the permission release message.
[0070] As one approach, after the second application stops acquiring device usage permissions for the target device, besides restoring the requested device usage permissions by receiving a permission release message, there are other ways to restore the requested device usage permissions. It should be noted that applications typically only acquire device usage permissions for the target device while they are running. For example, a voice call application only acquires microphone usage permissions while it is running. Therefore, when an application exits its running state (e.g., the application's main process is closed), it will no longer occupy device usage permissions. Furthermore, after the device usage permissions acquired by an application are occupied, the application whose device usage permissions were preempted may be switched to run in the background. For example, such as... Figure 6 As shown. In Figure 6 The image on the left exemplarily illustrates the interface 10 of a voice recognition application. Figure 6 In the case of the smartwatch display interface 10 shown, the voice recognition application currently has device access to the microphone. When the smartwatch detects an incoming call, the voice call application will start, causing the smartwatch to switch to display mode. Figure 6 The incoming call interface 20 is shown in the image on the right. When the smartwatch displays the incoming call interface 20, the voice call application has already obtained the device access permission for the microphone, while the voice recognition application, whose device access permission for the microphone has been taken over, has been switched to run in the background, or in other words, the interface of the voice recognition application is covered by the incoming call interface of the voice call application.
[0071] In this approach, an application that stopped requesting device usage rights in response to a permission occupancy message can determine whether to resume requesting device usage rights based on whether it has been switched to the foreground or whether other applications' interfaces are covering its own. Optionally, if an application that stopped requesting device usage rights in response to a permission occupancy message detects that it has switched to the foreground, it can determine that the application that previously preempted device usage rights has exited, and thus can request to acquire device usage rights for the target device. Optionally, if an application that stopped requesting device usage rights in response to a permission occupancy message detects that no other applications' interfaces are covering its own, it can determine that the application that previously preempted device usage rights has exited, and thus can request to acquire device usage rights for the target device.
[0072] It should be noted that while an application can determine which method to use to restore access to the requested device through multiple methods, it can also choose the specific method based on its own circumstances. One approach is for the application to determine which method to use to restore access to the requested device, provided it does not include a user interface (e.g., ...). Figure 6 In the case of interface 10 shown, the permission to use the requested device is restored according to the permission reply message. Correspondingly, if it is determined that it includes the user operation interface, the permission to use the requested device can be restored if it is detected that it is running in the foreground or that no other application interface is covering its own interface.
[0073] This embodiment provides an application control method that, after a first application requests device usage rights for a target device, if those rights are already occupied by a second application, sends a permission occupation message to the second application. This prevents the first application from re-acquiring device usage rights if it receives the message. Therefore, this method ensures that if the first application has already acquired device usage rights, and those rights are subsequently preempted by the second application, it will not continuously consume system resources by requesting device usage rights again, thus reducing waste of system resources.
[0074] Please see Figure 7 This application provides an application control method applied to a device management module, which manages the device usage permissions of a target device. The method includes:
[0075] S310: After the first application obtains the device usage permission of the target device, if it receives a request from the second application to obtain the device usage permission of the target device, it sends a permission occupation message to the second application to make the second application stop obtaining the device usage permission. The second application is the application that requested to obtain the device usage permission.
[0076] The permission occupancy message is used to notify the second application that the device usage permission has been occupied by another application.
[0077] It should be noted that the device management module is used to manage the device usage permissions of the corresponding devices. Before an application needs to use a target device, it can send a request to the device management module to obtain the corresponding device usage permissions. After receiving the request from the application, the device management module compares the usage priority of the requesting application with the usage priority of the application that has already obtained the target device. If the usage priority of the requesting application is not higher than the usage priority of the application that has already obtained the target device, the device management module will reject the request and continue to maintain the device usage permissions of the application that has already obtained the target device.
[0078] As one method, sending the permission request message to the second application includes:
[0079] A notification message is sent to the system service, which triggers the system service to send the permission occupancy message to the first application.
[0080] As one approach, if the first application obtains device usage permission corresponding to the target device and receives a request from the second application to obtain the device usage permission, after sending a permission occupation message to the second application, the method further includes: if the first application releases the device usage permission corresponding to the target device, sending a permission release message to the second application, so that the second application can resume requesting to obtain the device usage permission; the permission release message is used to notify the application that the device usage permission is in an idle state.
[0081] This embodiment provides an application control method that, after a first application requests device usage rights for a target device, if those rights are already occupied by a second application, the device management module sends a permission occupation message to the second application. This prevents the first application from re-acquiring device usage rights if it receives the message. Therefore, this method ensures that if the first application has already acquired device usage rights, and those rights are subsequently preempted by the second application, it will not continuously consume system resources by requesting new device usage rights, thus reducing waste of system resources.
[0082] Please see Figure 8 This application provides an application control device 400, which runs on an application. The device 400 includes:
