Description

Application program control method and mobile terminal

Technical Field

The invention relates to the technical field of mobile terminals, in particular to an application program control method and a mobile terminal.

At present, with the rapid development of mobile communication technology, mobile terminals (such as mobile phones) have become indispensable electronic consumer products in people's daily life, and with the increasing popularization of smart phones, smart phones have been integrated into various aspects of life, for example, smart phones have become main electronic products for information interaction between people. Meanwhile, the smart phone application also brings more profit opportunities to more service providers, each service provider develops respective application programs, and users install corresponding application programs, such as game applications, video applications, chat applications, shopping applications and the like, in the smart phone according to respective actual requirements.

Currently, related technologies provide an application running state control method, which mainly includes: judging whether the target application is foreground application, if the target application is determined to be foreground application, setting the current state of the target application to be an operating state, and displaying an interactive interface of the target application on a display screen frame by frame; and if the target application is determined to be the background application, setting the current state of the target application to be a suspended state (dormant state), and enabling the interactive interface of the target application to be still. When a certain application of the mobile terminal is actually operated, a certain invalid information interface may exist in the running process of the application, for example, for a video application, an advertisement playing interface may be regarded as an invalid information interface, for example, for a game application, a process of waiting for other participants to operate a game may be regarded as an invalid information interface, and for any application, an interactive interface which is not interested or concerned by a user may exist, and such an interactive interface may be regarded as an invalid information interface. Aiming at the condition that a target application runs in a foreground and receives an instruction for switching a new application to the foreground, the target application is covered by the new application and is automatically adjusted to the background as the new application is switched to the foreground, and the target application enters a pause state (a sleep state), so that an invalid information interface of the application can be displayed on a display screen frame by frame only when the application is positioned in the foreground; and once the application is tuned to the background, the application stays in a certain invalid information interface until the application is tuned to the foreground again, and the application is restored from the suspended state to the running state.

In summary, for any application of the mobile terminal, after the application is switched from the foreground application to the background application, the state of the application is automatically switched to the suspended state. Therefore, the application can be kept running only when the application is the foreground application, so that the user cannot operate other applications in the process of keeping the running state of the application, and the user experience is reduced.

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all 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 invention.

The embodiment of the invention provides an application program control method and a mobile terminal, wherein a first application is switched to a background and then is controlled to continue running, so that a user can control other applications on the foreground, in addition, the size of a display interface of the currently controlled application can be ensured to be unchanged, and the user operation experience is improved; and when the first application runs in the background, the running parameters of the first application are adjusted based on the current state change information of the mobile terminal, so that the foreground application and the running background application are controlled simultaneously, and the two applications are ensured not to be influenced by each other when running simultaneously.

In an embodiment of the present invention, a mobile terminal may be a mobile phone, a tablet computer, and the like, taking a mobile phone as an example, fig. 1 is a schematic flow chart of an application control method provided in an embodiment of the present invention, as shown in fig. 1, the method at least includes the following steps:

s101, when the first application is running in the foreground, judging whether a second application to be switched to the foreground to run is a preset application. For example, the first application is a video application, the second application is a chat application, when the video application is running in the foreground, the video application starts playing advertisements, the user needs to tune the chat application to the foreground to run, and the system automatically judges whether the chat application to be switched to the foreground to run is a preset application.

And S102, if yes, controlling the first application to be switched to the background and then to continue to operate, and controlling the second application to be switched to the foreground to operate. Specifically, the chat application can be preset as a preset application, so that after the chat application is tuned to the foreground to run, the video application is automatically switched to the background and kept running.

S103, adjusting the operation parameters of the first application which is running in the background according to the detected state change information of the mobile terminal, wherein the state change information comprises: angular velocity variation information and/or acceleration variation information, the operational parameters including: any one or more of a play parameter, a volume adjustment parameter, and a dynamic element control parameter, the dynamic element comprising: the virtual character in the preferred application has different operation parameters which need to be adjusted according to different applications.

The information of the change of the angular velocity of the mobile terminal is obtained by detecting an angular velocity sensor (such as a gyroscope), for example, an inclination angle of the mobile terminal to a preset direction changes by a first angle; the acceleration change information of the mobile terminal is detected by an acceleration sensor, for example, the mobile terminal moves a first distance in a preset direction and moves a second distance in a direction opposite to the preset direction.

In the embodiment provided by the invention, when the first application is running in the foreground, whether the second application to be switched to the foreground to run is a preset application is judged; if yes, controlling the first application to be switched to the background and then to continue to operate, and controlling the second application to be switched to the foreground to operate; and adjusting the operation parameters of the first application according to the detected state change information of the mobile terminal. The first application is controlled to continue to run after being switched to the background, so that the first application can also keep running when the first application is the background application, and a user can operate other applications in the foreground in the process of keeping running of a certain application, so that the time utilization rate of the user is improved, and the user experience is improved; in addition, for a mobile terminal with a limited screen size, the size of a display interface of a currently controlled application can be ensured to be unchanged by adopting a mode of simultaneous multi-task operation of a foreground and a background, and the operation experience of a user is improved; and when the first application runs in the background, the running parameters of the first application are adjusted based on the current state change information of the mobile terminal, so that the foreground application and the running background application are controlled simultaneously, and the two applications are ensured not to be influenced by each other when running simultaneously.

Wherein, can be based on user' S touch-control operation, realize the callout and pack up of second application, also can be based on the current running state of application, whether intelligent recognition is in the first application of foreground operation and need switch to the backstage, whether the second application needs to be transferred to the foreground operation, or whether intelligent recognition is in the second application of foreground operation and need switch to the backstage, whether the first application of background operation needs to be transferred to the foreground operation, thereby realize the quick switch between two applications, based on this, above-mentioned S103 is according to the state change information of the mobile terminal who detects, after the running parameter of the first application of background operation is adjusted, still include:

and determining the application to be switched to the foreground for running according to the running state of the first application and/or the running state of the second application.

Specifically, when the second application is running in the foreground and the first application is running in the background, the determining, according to the running state of the first application and/or the running state of the second application, the application to be switched to the foreground to run specifically includes:

(1) and for the situation that only the running state of the second application is considered, if the second application is determined to have no information to be processed currently, determining the first application running at the background as the application to be switched to the foreground for running.

For example, the first application is a video application, the second application is a chat application, and the process of determining whether to perform foreground and background switching between the first application and the second application is specifically:

and if the chat application is detected to send a message, determining the video application running in the background as the application to be switched to the foreground to run. In order to improve the switching accuracy, the word number of the sent message may be limited, specifically: and if the chat application is detected to send a message and the word number of the message is greater than the preset threshold value, determining the video application running in the background as the application to be switched to the foreground for running.

(2) For the situation that only the running state of the first application is considered, if the situation that the interactive interface of the first application running in the background needs to be displayed in the foreground is determined, the first application running in the background is determined as the application to be switched to the foreground to run; taking the first application as the video application as an example, the fact that the interactive interface needs to be displayed in the foreground means that the video application starts to play the video feature, that is, the video application finishes playing the advertisement in the background.

(3) For the situation that the running state of the first application and the running state of the second application are considered at the same time, if it is determined that the second application does not have information to be processed currently and the interactive interface of the first application running in the background needs to be displayed in the foreground, the first application running in the background is determined as the application to be switched to the foreground to run.

Specifically, when the first application is running in the foreground and the second application is located in the background, determining the application to be switched to the foreground for running according to the running state of the first application and/or the running state of the second application specifically includes:

(1) for the situation that only the running state of the second application is considered, if the second application is determined to have information to be processed currently, the second application is determined to be the application to be switched to the foreground to run;

and if the chat application is detected to receive a message, determining the chat application as the application to be switched to the foreground for operation.

(2) Aiming at the condition that only the running state of the first application is considered, if the interactive interface of the first application running in the foreground is determined to be an invalid information interface, determining the second application newly switched to the background as the application to be switched to the foreground to run; taking the first application as a video application as an example, the interactive interface being an invalid information interface means that the video application starts to play advertisements;

and if the video application running in the foreground is detected to enter the advertising time, determining the chat application as the application to be switched to the foreground for running.

(3) And if the second application currently has information to be processed and the interactive interface of the foreground running first application is determined to be an invalid information interface, determining the second application to be switched to the foreground running application.

In specific implementation, when the running state of the first application and the running state of the second application both meet the switching condition, switching between foreground and background applications is performed, so that the accuracy of application switching identification can be improved.

In addition, in order to improve the accuracy of application switching identification and further improve the switching accuracy between two applications, the method further includes:

and updating the running state set for determining the switching of the foreground and the background of the application based on the switching time of the foreground and the background of the application or the correction feedback information of the switching function input by a user.

The application foreground and background switching time refers to that when an application running in a foreground is in a preset running state, a user manually switches the application from the foreground to the background, or when an application located in the background is in the preset running state, the user manually switches a target application from the background to the foreground; the running state set includes a plurality of preset running states, where the preset running states are used to represent that the application having the preset running states needs to be switched from a foreground to a background or from the background to the foreground, for example, the running state set includes: the information to be processed does not exist in the second application currently, the information to be processed exists in the second application currently, the interactive interface of the first application needs to be displayed in the foreground, the interactive interface of the first application is an invalid information interface, and the like.

Correspondingly, the determining the application to be switched to the foreground for running according to the running state of the first application and/or the running state of the second application specifically includes:

judging whether the running state of the first application and/or the running state of the second application belong to the running state set or not; and determining the application to be switched to the foreground for operation according to the judgment result.

Specifically, a process of adjusting an operation parameter of a first application running in a background based on state change information of a mobile terminal is described for the following application scenarios, specifically:

for example, as shown in fig. 2a, an application currently running in the foreground is a video application, and when the video application cannot skip an advertisement during playing of the advertisement, it is determined that the video application needs to be switched to the background and then continuously run, and a chat application needs to be switched to the foreground to run, at this time, a user may operate the chat application in the foreground, and the video application continues to play the video advertisement in the background; as shown in fig. 2b, the video application is retracted and hidden to the background, and the video application continues to play the advertisement, and meanwhile, the chat application is tuned to the foreground for operation, at this time, the user can adjust the operation parameters of the video application by changing the state change information of the mobile terminal, for example, adjust the volume of the played advertisement, and after the advertisement of the video application is played, it is determined that the video application needs to be tuned to the foreground for operation, and the chat application needs to be switched to the background; as shown in fig. 2c, the video application is switched back to foreground operation and the chat application is switched to background.

It should be noted that the above application scenarios are specific examples provided for easy understanding, and do not limit the technical solution of the present invention.

Further, as shown in fig. 3, before the step S101 of determining whether the second application to be switched to the foreground for running is the preset application when the first application is running in the foreground, the method further includes:

and S104, setting at least one application installed in the mobile terminal as a preset application.

Specifically, the preset applications may be manually set by a user according to respective actual requirements, and in order to facilitate the user to quickly set a certain application as the preset application, in the embodiment provided by the present invention, a first implementation manner for quickly adding a certain application as the preset application is provided, and specifically, the implementation manner is that:

the step S104 of setting at least one application installed in the mobile terminal as a preset application specifically includes:

displaying a first floating control on a display screen of the mobile terminal, wherein during specific implementation, a first floating control needs to be generated in advance, and a touch operation for instructing calling out the first floating control is predefined.

And if the icon is detected to move to the position of the first floating control, setting the application corresponding to the icon as a preset application, and restoring the icon to the original position after the touch operation of the user on the icon is detected to be released.

In the embodiment provided by the invention, the suspension control is generated in advance, and when the fact that the user needs to add the specified application as the preset application is determined, the suspension control is automatically displayed, so that the user can set the application as the preset application by dragging the application icon to be added as the preset application, the setting efficiency of the preset application is improved, and the user operation is facilitated.

Further, considering that an application which is not added as a preset application in advance may need to be set as a preset application in the process of operating the first application according to the real-time processing requirement of each application in the mobile terminal, therefore, in order to improve the pertinence, flexibility and diversity of the preset application setting, various implementation manners for quickly setting the preset application are provided for a user to select, and the requirement that the user quickly sets different applications as the preset applications at different stages is met, a second implementation manner for quickly adding a certain application as the preset application is also provided in the embodiment provided by the present invention, and specifically:

when determining that information to be processed of a certain application is to be processed, generating and displaying a second floating control, wherein the information to be processed can be information to be processed for receiving and sending, and can be directed to applications with information receiving and sending functions, such as chat applications, or can be information to be processed for recommending, and can be directed to applications with information recommending functions, such as information applications;

and if the clicking operation of the user on the second suspension control is detected, setting the application with the information to be processed as a preset application.

In the embodiment provided by the invention, in the process of operating a certain application by a user, if another application has information to be processed, at the moment, when the information processing prompt is performed on the user, a second suspension control is added, so that the user can set the application with the processing requirement as the preset application in real time, even if the user does not click to open during the message prompt, invalid information is displayed in the first application subsequently, and the preset application is required to be opened, the required application program can be called quickly, and the first application is controlled to be called to the background and then continuously run, so that the pertinence and flexibility of the setting of the preset application are improved, the processing requirements of the user at different stages can be met, and the user experience is greatly improved.

Specifically, in order to realize the intellectualization of the preset application setting and improve the use experience of the user, for the situation that the user does not perform the preset application setting, the preset application may also be automatically set according to the historical application switching habit system of the user, based on which, the above S104 sets at least one application installed in the mobile terminal as the preset application, specifically including:

when the first application is running in the foreground, the preset application associated with the first application is determined by utilizing the preset application identification model. In specific implementation, the first application may be manually set in advance, or may be automatically set by the system, for example, the system defaults to add an application, such as a video application and a game application, that needs to be kept running in the background to the first application set, when an application is running in the foreground, determines whether the application belongs to the first application set, if so, determines that the first application is running in the foreground, and if it is also determined that a request for setting a preset application for the first application by a user is not received, automatically performs a step of determining the preset application associated with the first application by using a preset application identification model.

Specifically, in order to be able to intelligently match any first application with a corresponding preset application, the method further includes:

for each first application, recording an application switching log of the first application, wherein the application switching log comprises: the name of the first application and the name of the application which is switched with the first application in the foreground and background are in corresponding relation; and/or the presence of a gas in the gas,

for each first application, storing a preset application setting log of the first application, wherein the preset application setting log comprises: the method comprises the following steps that the name of a first application and the received name of a preset application set by a user for the first application are in corresponding relation;

and taking the application switching log and/or the preset application setting log as a training sample set.

The application switching log can accurately reflect the application switching preference of the user, the preset application setting log can more accurately reflect the application switching preference of the user, the preset application matched with the first application running at the current foreground can be intelligently identified by combining the application switching log and/or the preset application setting log, the user does not need to manually set the preset application, the user can perform touch operation subsequently, the first application and the preset application can be quickly switched, and the first application can be ensured to continue to run after being switched to the background.

The preset application recognition model can be obtained by training the cloud server or the mobile terminal in the following mode, specifically:

obtaining a training sample set of a mobile terminal, wherein the training sample set comprises: an application switching log and/or a preset application setting log;

and training to obtain a preset application recognition model by adopting a deep learning method and based on a training sample set.

And then, inputting the name of the first application running in the foreground into a preset application identification model, namely automatically identifying the preset application, outputting a corresponding identification result, and further determining the preset application matched with the first application.

As shown in fig. 4, the adjusting, by the S103, the operation parameter of the first application running in the background according to the detected state change information of the mobile terminal specifically includes:

s1031, based on the corresponding relation between the prestored state change information and the operation parameters, searching the target operation parameters corresponding to the detected state change information of the mobile terminal;

and S1032, adjusting the operation parameters of the first application which is operated in the background according to the target operation parameters.

Specifically, for example, by analyzing the change of the collected data of the angular velocity sensor, if it is determined that the display screen of the mobile terminal is tilted to the left or right by a preset angle, the fast forward or backward, the volume up or down, or the direction of movement of the main character in the first application (e.g., a game application) running in the background is controlled.

For another example, by analyzing the change of the data acquired by the acceleration sensor, if it is determined that the mobile terminal moves quickly a first distance in a first preset direction and returns slowly to a second distance, the first application running in the background is controlled to continuously execute the operation in the first preset direction until the mobile terminal suddenly moves quickly a third distance in the second preset direction and returns slowly to the second distance, and the first application running in the background is controlled to pause running. The operation parameters of the first application are adjusted by adopting a mode of quickly moving towards one direction and slowly returning, so that the recognition interference caused by irregular shaking on the vehicles such as buses or subways can be avoided.

In addition, in order not to affect the operation of the user on the foreground application, the maximum value of the angular velocity information (i.e. the tilt angle) of the mobile terminal is preferably set within 30 degrees, that is, the operating parameter corresponding to the tilt angle of the mobile terminal reaching 30 degrees is that the fast-backward speed or the fast-forward speed reaches the maximum value.

Furthermore, the situation of wrong response control caused by error identification or user misoperation is avoided, so that the purpose of accurate response control is achieved, unnecessary troubles brought to the user are avoided, and the user experience is improved. Based on this, as shown in fig. 5a, before the step S103 adjusts the operation parameters of the first application running in the background according to the detected state change information of the mobile terminal, the method further includes:

s105, judging whether the detected triggering operation of the user is consistent with a preset triggering condition;

if the state change information of the mobile terminal is consistent with the state change information of the mobile terminal, step S103 of adjusting the operation parameters of the first application running in the background is executed.

Furthermore, another implementation mode for avoiding wrong response control caused by false identification or user misoperation is provided, so that the purpose of accurate response control is achieved, unnecessary troubles are avoided for users, and user experience is improved. Based on this, as shown in fig. 5b, before the step S103 adjusts the operation parameters of the first application running in the background according to the detected state change information of the mobile terminal, the method further includes:

s106, judging whether the user uses the mobile terminal or not according to the image information acquired by the camera device of the mobile terminal;

if yes, executing step S103 of adjusting the operation parameters of the first application running in the background according to the detected state change information of the mobile terminal.

When the method is implemented specifically, in order to avoid false triggering, a triggering condition may be set in advance, where the preset triggering condition may be that two fingers perform two-point touch operation on a display screen or that a volume button is pressed once; or, in order to avoid false recognition and false operation, the camera is opened to recognize whether the current face and eyeball are directly opposite to the display screen of the mobile terminal, and if the face and eyeball are not detected, the motion of the mobile terminal is considered to be interference from external motion at the moment without adjusting the operation parameters of the first application.

Specifically, for a certain application, the state of the application includes: the first application is in a running state no matter in the foreground or in the background, and the keeping running means controlling the first application to continue running in the background. When the first application keeps running in the background, the display coordinate range where the interactive interface of the first application is located is not within the coordinate range of the display screen, at the moment, the interactive interface of the second application is displayed on the display screen, and the interactive interface of the first application and the interactive interface of the second application are not overlapped; or the display coordinate range of the interactive interface of the first application is within the coordinate range of the display screen, the interactive interface of the second application is displayed on the uppermost layer of the display screen at the moment, and the interactive interface of the first application is not covered by the interactive interface of the second application, so that the interactive interface of the first application cannot be displayed on the display screen during background operation, and the operation parameters of the first application during background operation are the same as the operation parameters of the first application during foreground operation. For example, for a foreground application of a mobile terminal, when the foreground application is running an invalid information interface, other applications can be called to the foreground, so that a user can operate the other applications, at this time, the original foreground application is moved to the background, changed into a background application without displaying an interactive interface on a display screen or changed into a background application without displaying the interactive interface on the top layer of the display screen, and meanwhile, the application is kept running continuously on the background, so that the time for the user to wait for the interactive interface to be displayed on the display screen frame by frame is reduced.

Specifically, if yes, the step S102 of controlling the first application to continue to operate after being switched to the background, and controlling the second application to be tuned to the foreground to operate specifically includes:

and if the second application is a preset application, moving the first application from the foreground stack to a target stack, wherein the target stack is pre-established and the level of the target stack is the same as that of the foreground stack, and the display parameters, corresponding to the foreground stack and the target stack, for indicating the size of the application display interface are all consistent with the size of the display screen. In specific implementation, the target stack and the foreground stack are two different stacks, and at least two applications can be run simultaneously by adopting a stack splitting management mode.

Controlling the first application to continue running in the target stack, controlling the second application to run in the foreground stack, controlling the interactive interface of the second application to be displayed on the display screen, and controlling the display coordinate range of the interactive interface of the first application not to be within the coordinate range of the display screen, or controlling the display coordinate range of the interactive interface of the first application to be within the coordinate range of the display screen and the interactive interface of the second application to be displayed on the uppermost layer of the display screen.

Specifically, as the level of the target stack is the same as that of the foreground stack, and the target stack contains one application, the application in the target stack cannot be shielded because the application is transferred to the background and is always in a visible state, so that the application in the target stack cannot lose focus, and the system automatically controls the first application to continue to run in the background; meanwhile, the display parameters which correspond to the foreground stack and the target stack and are used for indicating the size of the application display interface are consistent with the size of the display screen, so that the interactive interface of the application which is transferred to the foreground can be displayed in a full screen mode.

In addition, considering that each stack may only include one application or may include a plurality of applications, and in case that the target stack includes a plurality of applications, after moving the first application from the foreground stack to the target stack, the method further includes:

placing the first application at the topmost end of the target stack; that is to say, not only the level of the target stack is the same as the level of the foreground stack, but also the first application needs to be placed at the topmost end of the target stack, so that the stack where the first application is located is in a visible state, and the first application is also in a visible state, and at this time, the system automatically controls the first application to continue to run in the background.

Specifically, when detecting that a certain application is to enter a background from a foreground, judging whether the application needs to be kept running in the background, if so, moving the application from the foreground stack to a target stack, placing the application at the topmost end of the target stack, and controlling the application to run in the target stack. The target stack is the same as the foreground stack in level, so that the application switched to the background is kept running.

The application program control method in the embodiment of the invention judges whether a second application to be switched to the foreground for running is a preset application when a first application is running in the foreground; if yes, controlling the first application to be switched to the background and then to continue to operate, and controlling the second application to be switched to the foreground to operate; and adjusting the operation parameters of the first application according to the detected state change information of the mobile terminal. The first application is controlled to continue to run after being switched to the background, so that the first application can also keep running when the first application is the background application, and a user can operate other applications in the foreground in the process of keeping running of a certain application, so that the time utilization rate of the user is improved, and the user experience is improved; in addition, for a mobile terminal with a limited screen size, the size of a display interface of a currently controlled application can be ensured to be unchanged by adopting a mode of simultaneous multi-task operation of a foreground and a background, and the operation experience of a user is improved; and when the first application runs in the background, the running parameters of the first application are adjusted based on the current state change information of the mobile terminal, so that the foreground application and the running background application are controlled simultaneously, and the two applications are ensured not to be influenced by each other when running simultaneously.
