Detailed Description

The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.

Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Fig. 1 is a flowchart of an application preloading method according to an embodiment of the present application, where the method may be performed by an application preloading device, where the device may be implemented by software and/or hardware, and may be generally integrated in a mobile terminal. As shown in fig. 1, the method includes:

step 101, receiving an unlocking operation acting on the mobile terminal.

For example, the mobile terminal in the embodiment of the present application may include mobile devices such as a mobile phone, a tablet computer, and a notebook computer.

Due to the reasons of protecting user privacy, preventing misoperation and the like, the mobile terminal generally provides a locking function, including locking of a mobile terminal system and locking of a display screen, and the like, and specific locking objects are not limited in the application. When the mobile terminal is in a locked state, a user is required to actively input an unlocking operation for unlocking, and when the unlocking operation is correctly input, the mobile terminal can be unlocked. With the continuous development of security technologies of mobile terminals, unlocking modes are more and more abundant, for example, character string (including letters, symbols, numbers, or the like) unlocking, graphic gesture unlocking (including touch gestures, space gestures, and the like), fingerprint unlocking, iris unlocking, face unlocking, and the like may be included, and the types of unlocking operations are not limited in the present application. In this step, an unlocking operation applied to the mobile terminal is received while the mobile terminal is in the locked state.

And step 102, determining a corresponding candidate application program set according to the input mode of the unlocking operation.

For different unlocking operation types, corresponding input modes are generally different, for example, digital unlocking requires a user to input a number with preset digits, and fingerprint unlocking requires the user to input own fingerprint, so that different unlocking operation input modes in the application can include inputting different types of unlocking operations. Furthermore, there may be different input modes for the same type of unlocking operation. Taking the unlocking of the character strings as an example, a plurality of groups of character strings can be set, and each two groups of character strings are different (for example, one group of character strings is all numbers, one group of character strings is all letters, one group of character strings is all symbols, and the like), so that a plurality of input modes can be provided, and the plurality of groups of character strings can successfully unlock the mobile terminal; taking graphical gesture unlocking (including touch gestures, air separation gestures and the like) as an example, various gesture tracks can be set, the input modes of the gesture tracks are different, and the gesture tracks can successfully unlock the mobile terminal; taking fingerprint unlocking as an example, fingerprint images corresponding to a plurality of fingers of a user can be recorded in advance as unlocking templates, such as a right thumb, a right index finger, a left thumb, a left index finger and the like, and the input modes of each finger are different, so that each finger can successfully unlock the mobile terminal; taking iris unlocking as an example, the method can be divided into modes of inputting left-eye irises, inputting right-eye irises, inputting both eyes irises simultaneously and the like; taking face unlocking as an example, the input modes can be divided into an upper half part of a face, a lower half part of the face, a left half part of the face, a right half part of the face, a whole face and the like.

In the embodiment of the present application, the dividing manner of the candidate application program set is not limited. For example, the applications may be classified according to application types, that is, applications belonging to the same type are divided into a set of candidate applications corresponding to the type. The application type may be classified into social, office, game, shopping, property, photography and video, education, etc. according to the personal needs of the user or default classification in the application store. The candidate application set may also be divided according to folders, that is, the application programs belonging to the same folder are divided into the candidate application set corresponding to the folder, and the name of the folder may be used as the name of the corresponding candidate application set. The candidate application program set may also be divided in a manner of dividing a desktop interface, that is, the application programs corresponding to the application icons belonging to the same desktop interface are divided into the candidate application program set corresponding to the desktop interface, and the serial number of the desktop may be used as the name of the corresponding candidate application program set. The candidate application program set may also be divided according to a historical operation rule of the application program, for example, a plurality of frequency intervals are set, and the frequency intervals are divided into a certain frequency interval according to the use frequency of the application program in a historical period (for example, in about 1 month), and each frequency interval corresponds to one candidate application program set. In addition, the dividing mode of the candidate application program set can also be freely set by a user, for example, a dividing list is maintained in the mobile terminal, and the user can add an application program to each candidate application program set according to the actual requirement of the user.

For example, the corresponding relationship between different unlocking operation input modes and the candidate application program set can be preset. For example, a fingerprint unlocks a corresponding office class candidate application set, a face unlocks a corresponding entertainment class candidate application set, a gesture unlocks a corresponding social class candidate application set, and a graph unlocks a corresponding shopping class candidate application set; for another example, a right thumb corresponds to the first desktop interface, a right index finger corresponds to the second desktop interface, a left thumb corresponds to the third desktop interface, and a left index finger corresponds to the fourth desktop interface; for another example, the folder a corresponding to the circular input track, the folder B corresponding to the "L" -shaped input track, the folder C corresponding to the triangular input track, the folder D corresponding to the square input track, and the like, and of course, the touch gesture and the air-separating gesture (no physical contact exists between the hand and the display screen) with the same track may also correspond to different candidate application program sets respectively.

In the embodiment of the application, after the unlocking operation is received, the input mode of the unlocking operation is determined, and the candidate application program set corresponding to the current input mode is searched according to the corresponding relation between the input mode and the candidate application program set and is used for the subsequent prediction operation.

And 103, determining the target application program to be preloaded contained in the candidate application program set.

For example, the target application to be preloaded may be an application that a user may be about to open after the mobile terminal is unlocked, and may be an application predicted in a certain manner. The target application to be preloaded may comprise one or more.

Optionally, a preset prediction model may be used to predict the application to be preloaded. The prediction model may be a machine learning model, and the algorithm used may include a Recurrent Neural Networks (RNN), a Long Short-Term Memory (LSTM) network, a threshold cycle unit, a simple cycle unit, an auto-encoder, a decision tree, a random forest, a feature mean classification, a classification regression tree, a hidden markov, a K-nearest neighbor (KNN) algorithm, a logistic regression model, a bayesian model, a gaussian model, and a KL divergence (Kullback-Leibler) or the like.

Optionally, in the process that the user uses the mobile terminal, a training sample may be collected, the training sample is adopted to train the preset initial model, and finally, the preset prediction model for predicting the application program to be preloaded is obtained. For example, the elements included in the training sample may include the time, place, frequency, etc. when the application was opened; the operation state of the terminal can be included, such as the on-off state of a mobile data network, the connection state of a wireless hotspot, the identity information of the connected wireless hotspot, a foreground application program before the mobile terminal is locked, the plugging state and the charging state of an earphone jack, the battery capacity information and the like; and the data collected by sensors integrated in the mobile terminal, such as a motion sensor, a light sensor, a temperature sensor, a humidity sensor and the like, can also be included.

For example, a suitable sample element may be selected according to the selected machine learning model, the selected machine learning model may be determined according to the selected sample element, and the model and the sample element may be selected according to requirements on prediction accuracy, a preset speed, and the like, which is not limited in the embodiment of the present application.

For example, when the preset prediction model performs prediction, all application programs in the mobile terminal may be considered, a plurality of application programs to be preloaded are predicted, and then an intersection of the application programs to be preloaded and the candidate application program set is selected as a target application program to be preloaded. The advantage of this arrangement is that the model training process can be simplified and a common predictive model can be used for prediction. For example, a plurality of predicted application programs to be preloaded can be marked as application a, application b, application c and application d, and through comparison of a candidate application program set corresponding to the current input mode, if only application a and application c belong to the candidate application program set, application a and application c are determined as target application programs, and application b and application d are excluded.

In the embodiment of the application, the working time of the preset prediction model is not limited, for example, the preset prediction model can be used for predicting the application program to be preloaded in the process of receiving the unlocking operation acted on the mobile terminal; and after the candidate application program set is determined, predicting the application program to be preloaded by using a preset prediction model and the like. The specific process of predicting the application program to be preloaded by using the preset prediction model is not limited, and for example, the specific process may include collecting a current sample, inputting the current sample into the preset prediction model, and determining the predicted application program to be preloaded according to an output result of the preset prediction model.

Optionally, in this embodiment of the application, prediction models may also be set for different candidate application sets, and in the training process of a prediction model corresponding to one candidate application set, only the operation rules of the application programs included in the candidate application set may be considered, so as to improve the model training speed. Illustratively, this step may include: and determining the target application program to be preloaded contained in the candidate application program set by utilizing the prediction model corresponding to the candidate application program set. The method has the advantages that after the candidate application program set is determined, the target application program is predicted by adopting the corresponding prediction model, all prediction ranges can be realized, and the prediction speed is improved. The algorithm based on the prediction model and the selection of the sample elements can refer to the corresponding contents in the foregoing, and the details are not repeated here. In addition, aiming at different candidate application program sets, different algorithms and different sample elements can be adopted in the process of training the prediction model, so that the personalized prediction model can be set for each candidate application program set in a more targeted manner, and the pertinence and the accuracy of the prediction model are improved.

And 104, preloading the target application program.

In the embodiment of the application, when only one target application program exists, the preloading sequence of the application is not required to be considered; when there are multiple target application programs, the multiple target application programs may be determined one by one as the current application program to be preloaded, and the preloading operation is performed sequentially, or more than 2 target application programs may be determined as the current application program to be preloaded, and the preloading operation is performed simultaneously, that is, the preloading processes of the multiple application programs may be performed in parallel.

In the embodiment of the present application, the specific process of preloading and the loaded resources are not limited, for example, corresponding hardware resources may be allocated to the target application program to be preloaded, and relevant data required for starting is loaded based on the allocated hardware resources. The method comprises the following steps of starting an application process, starting an application service, allocating memory, reading file content, acquiring network data, rendering an interface and the like. Furthermore, the resources to be preloaded may be determined according to the specific type of application to be preloaded. For example, if the application to be preloaded is a social software, a start screen, a contact list, a recent message record, and the like in the application may be preloaded; if the application program to be preloaded is a game, the game background related data in the application program can be preloaded.

Optionally, after the target application program is preloaded, when an operation instruction of the target application program is received, the target application program corresponding to the operation instruction is started based on the preloaded resource.

The application program preloading method provided in the embodiment of the application program preloading method receives unlocking operation acting on the mobile terminal, determines a corresponding candidate application program set according to an input mode of the unlocking operation, determines a target application program to be preloaded contained in the candidate application program set, and preloads the target application program. By adopting the technical scheme, the corresponding candidate application program set can be determined by combining the input mode of the unlocking operation actively input by the user, so that the subjective intention of the user is met, the prediction range can be narrowed, the application program which the user wants to use after the mobile terminal is unlocked is accurately determined, the determined application program is preloaded, and the starting speed of the application program is improved.

In some embodiments, the unlock operation comprises a graphical unlock gesture. The determining a corresponding candidate application program set according to the input mode of the unlocking operation includes: and determining a corresponding candidate application program set according to the input track of the graph unlocking gesture. The advantage of this arrangement is that the input trace style of the graphical unlocking gesture is rich, and more candidate application program sets can be matched.

In some embodiments, the determining the respective set of candidate applications according to the input trajectory of the graphical unlock gesture includes: determining a target desktop entering after unlocking according to the input track of the graph unlocking gesture; and determining the application program corresponding to the application icon contained in the target desktop as a candidate application program set corresponding to the input track. The method has the advantages that the corresponding relation between the input track and the candidate application program set can be simplified, when the candidate application program set to which a certain application program belongs needs to be adjusted, the desktop icon of the application program is directly moved to the adjusted desktop interface, in addition, the corresponding relation between the input track and the desktop interface can be conveniently memorized by a user, and the corresponding target desktop can be quickly and accurately determined through the input track in the input memory. In addition, after the mobile terminal is successfully unlocked, the display screen can automatically display the target desktop instead of displaying the default desktop interface, and the time for searching the application program to be started by switching the desktop interface by the user can be further reduced.

In some embodiments, the determining a corresponding candidate application program set according to the input mode of the unlocking operation includes: and determining a corresponding candidate application program set according to the finger type of the input fingerprint unlocking operation. The advantage of this is that the user typically has 10 fingers that can match a sufficient set of candidate applications, and in addition, fingerprints are biometric, highly secure and easy to remember. In addition, the corresponding candidate application program set can be determined according to the input multiple finger categories, the input times of each finger category and the input sequence. For example, the left thumb is input first, and then the right thumb is input to correspond to the first candidate application program set; inputting a right thumb and then inputting a left thumb corresponding to a second candidate application program set; inputting the left thumb twice in succession corresponds to a third candidate application set, and so on.

Further, determining a corresponding candidate application program set according to the finger type of the input fingerprint unlocking operation includes: determining a target desktop entering after unlocking according to the finger type of the input fingerprint unlocking operation; and determining the application program corresponding to the application icon contained in the target desktop as a candidate application program set corresponding to the finger category. Similarly, the setting has the advantages that the corresponding relation between the fingers and the candidate application program set can be simplified, the application programs contained in the candidate application set can be conveniently adjusted, in addition, the corresponding relation between the fingers and the desktop interface can be further conveniently memorized by a user, and further the corresponding target desktop can be quickly and accurately determined by inputting the memorized fingers. In addition, after the mobile terminal is successfully unlocked, the display screen can automatically display the target desktop instead of displaying the default desktop interface, and the time for searching the application program to be started by switching the desktop interface by the user can be further reduced.

In some embodiments, the preloading the target application includes: and starting preloading the target application program in the process of verifying the unlocking operation. The advantage of this arrangement is that the preloading operation can be performed earlier, and the preloading completion probability or the preloading completion degree when the target application program is actually started by the user is improved. Generally, for various unlocking modes, the mobile terminal needs to verify the currently input unlocking operation, and can unlock the mobile terminal after the verification is successful, and the verification process usually takes a certain time, and generally, the more complicated the unlocking operation or the higher the security performance is, the longer the verification time needs to be taken. In the embodiment of the application, after the mobile terminal receives the unlocking operation acting on the mobile terminal, the input mode of the mobile terminal can be known, the target application program can be quickly obtained, and then the preloading operation can be immediately started, so that the target application program can be preloaded before the unlocking verification operation is completed. If the verification is successful and the preloading operation is not finished yet, the preloading can be continued, and if the preloading is finished, the user can be waited to start the application program; if the verification fails, the system resources occupied by the preloading operation can be released.

In some embodiments, the preloading the target application includes: and preloading the target application program according to the preloading strategy corresponding to the candidate application program set. The advantage of this arrangement is that it is possible to design personalized preloading strategies for different sets of candidate applications, meeting different preloading requirements. The preload policy may include which boot resources to preload, or the type of boot resources to preload. As described above, the preloading procedure may include application process starting, application service starting, memory allocation, file content reading, network data acquisition, interface rendering, and the like, some of which may not be necessary, and may be designed according to characteristics of the application programs included in each candidate application set. For example, some applications may involve less network data or frequent network side updates when starting, and may not be preloaded; for another example, some application programs do not need to play advertisement pictures when being started, and interface rendering and the like are not needed.

In some embodiments, the preloading the target application includes: and preloading an application interface corresponding to the target application program based on a pre-created pre-loaded active window stack, wherein the boundary coordinate corresponding to the pre-loaded active window stack is positioned outside the coordinate range of the display screen.

In the embodiment of the present application, the active window may be understood as a separate interface directly providing interaction and operation for a user, and different names may be used in different operating systems to name the interface. For ease of understanding, the following description will be made taking an Android (Android) operating system as an example.

In the Android system, the active window is called Activity. Activity is a component responsible for interacting with a user that provides a screen (which may be understood as a screen interface, rather than a display screen of an entity) for the user to interact to accomplish a task. In an android application, an Activity is usually a separate screen on which controls can be displayed and events of the user can be monitored and processed. In managing Activity, there are two concepts: task Stack and Stack. The Task corresponds to an application program, the Task is used for storing activities, one Task can store one or more activities, and the activities follow the principle of first-in first-out and last-in first-out. And the Stack is used for managing the Task, generally, one Stack manages the Task to which each Activity required to be shown by one screen belongs, and one Stack can manage one or more tasks, and of course, the Stack also follows the basic management principle of the Stack. The screens described herein are not necessarily completely separate display screens, and in the case of "two screens", the two screens may be only two regions of a complete display screen that independently display respective display contents. Of course, if the terminal has two or even more separate display screens, the "two screens" may also be two separate display screens.

In the Android system, multi-window modes are supported, which may include split screen mode, picture-in-picture mode, and free mode (FreeForm). In the multi-window mode, the Stack in which the application is located may have its own size (size), and may include upper, lower, left, and right coordinates in a coordinate system with the upper left corner of the terminal screen as the origin. For example, (a, b, c, d), which generally describes the boundary of a rectangle, the coordinates of the upper left corner and the coordinates of the lower right corner of the rectangle can be used for representation, i.e. the coordinates of the upper left corner of the rectangle are (a, b), and the coordinates of the lower right corner are (c, d), and such a rectangular area corresponds to the size of Stack. The in-application layout in the Stack is based on the size of the Stack, that is, the application interface corresponding to Activity is displayed within the boundary range of the size.

In the multi-window mode, multiple applications may be allowed to be visible, including both system and user visibility and system-only visibility. The system and the user can see the display on the display screen, and the user can see the display; system-only-visible means that the operating system is visible, but not the user, and may be obscured by foreground applications or displayed outside the display screen as the application is intended to implement.

In the embodiment of the application, the application interface of the target application program is preloaded outside the display screen, the preloading can be realized based on a multi-window mechanism of an operating system, and the size corresponding to the application program is set outside the display screen through the multi-window mechanism so as to achieve the purpose of being invisible to a user, so that the display of the display content of the foreground application program on the display screen is not influenced.

Generally, in the multi-window mode, there may be multiple types of stacks, for example, Home Stack represents a Stack displayed by a desktop application, App Stack represents a Stack displayed by a third-party application, and there may be other split-screen stacks, and contents contained in the three types of stacks may be displayed on a display screen, which are collectively referred to as application active window stacks in this embodiment. In the embodiment of the application, a preloaded active window Stack (preloaded Stack) is added to indicate a Stack displayed by a preloaded application, and the boundary coordinates of the preloaded Stack are set to be outside the coordinate range of a display screen, so that an application program to be preloaded can be displayed on the Stack. For the Android system, a Stack special for displaying preloaded applications can be newly built based on a multi-window mechanism of the Android system. In the embodiment of the application, the reason for newly building the Stack is that the newly built preloaded Stack can own size and visibility, so that the purpose of preloading outside a display screen is achieved.

In the embodiment of the application, the creation time of the preloaded Stack is not limited, and the preloaded Stack can be set to be in a resident state by default before the terminal leaves a factory, namely the preloaded Stack exists all the time; the method can also be established when the terminal is started or after the terminal is successfully unlocked; it may also be created after an application preload event is triggered (which may be before the target application is determined), and so on. Optionally, the preloading an application interface corresponding to the target application program based on a pre-created active window stack includes: judging whether a pre-established preloading active window stack exists or not; if not, creating a preloaded active window stack according to a preset rule; and preloading an application interface corresponding to the target application program based on the created preloading active window stack. The method has the advantages that after the target application program to be preloaded is determined, whether the preloading Stack exists or not is judged, if yes, new construction is not needed, and if not, creation is carried out, so that system resources can be saved. It can be understood that, when a plurality of target applications are included, that is, when a plurality of applications need to be continuously preloaded in a short time, the preloaded Stack is already created before the first target application starts to load, and then the preloaded Stack exists before the second target application starts to load, which may not be necessary.

In the embodiment of the application, a specific process of preloading an application interface corresponding to a target application program based on the preloaded Stack is not limited, and for example, the application interface may be drawn and displayed based on the size of the preloaded Stack.

In some embodiments, the preloading an application interface corresponding to the target application program based on a pre-created preload active window stack includes: creating a target process corresponding to the target application program; creating a task stack corresponding to the target application program in a pre-created preloading active window stack; starting an active window corresponding to the target application program in the task stack based on the target process; and drawing and displaying an application interface corresponding to the target application program based on the started active window. The advantage of setting up like this lies in, can draw and show the application interface of target application program based on the preloading activity window stack outside the screen coordinate scope, can not disturb the operation and the demonstration of foreground application program, guarantees system stability, effectively improves the speed when target application program starts simultaneously. While creating the target process, an initialization process of the target process may also be included. In the execution process of the above steps, preloading of other resources may also be involved, such as application service starting, memory allocation, file content reading, network data acquisition, and the like.

In some embodiments, further comprising: and sending a fake focus notification to the target application program, and keeping continuous drawing and display updating of an application interface corresponding to the target application program in a preset time period based on the fake focus notification. The method has the advantages that the drawing and the display of the application interface can be completed under the condition that the target application program obtains the focus and is visible to the system, the preloading completion degree is improved, and the focus of foreground application is not affected. The focus in the embodiment of the present application is also referred to as an input focus, and the fake focus is independent from the focus corresponding to the foreground application. Generally, for the current Android system, a focus is unique, for example, input operations such as touch and the like only take effect on the focus, the system end and the application end are consistent for inputting focus information, and once the system end modifies the input focus information, the system end sends information that the input focus information changes to the application, so that the method ensures that the input focus information of the system end and the application end is consistent. In the embodiment of the application, the purpose that the application end can forge the focus is achieved by separating the mode that the system end and the application end input the focus information. Specifically, in the embodiment of the application, the focus information is forged for the preloaded application, so that the preloaded application has the focus information, and the focus information of the system end is still correct, so that the preloaded application can be drawn normally, and the purpose of full loading is achieved. The focus exists in the system end and the application end, which can be regarded as a server end (server) and a client end (client), the system end records the application with the focus, and the application end stores a flag bit (flag) to identify whether the application has the focus. The time for forging the input focus can be that when a new window of the Android window system is added and the focus needs to be updated, a forged focus notification is generated and sent. The method for forging the focus may be a method for changing the focus of the window by calling the client end of the window, so that the window acquires the focus. Specifically, the forged focus notification can be sent based on a Binder mechanism, which is the most common mode of interprocess communication of the Android system and adopts a c/s architecture, i.e., a client/service architecture.

In the embodiment of the present application, the preset time period may be designed according to actual situations, and may be, for example, within a fixed time length range after the start of the preloading, or a time period from the start of the preloading to the completion of the preloading, and the like. In some embodiments, the length of the preset time period includes a playing time length of the start advertisement or start animation in the target application program. Some application programs usually play some advertisements or animations during the starting process, the playing time of the advertisements or animations usually ranges from 3 seconds to ten seconds, and during the playing of the advertisements or animations, a user may not have any operation and only wait for the completion of the playing, which wastes valuable time of the user. The method and the device have the advantages that the starting advertisement or the starting animation can be played out of the screen before the target application program is started, and when the target application program is started, the main page or other user operable interfaces of the application program can be directly accessed, so that the operable time point of the target application program is further advanced, and the waiting time is reduced.

In some embodiments, after preloading the application interface corresponding to the target application program based on the pre-created preloading active window stack, the method further includes: and when an operation instruction of the target application program is received, transferring an application interface corresponding to the target application program corresponding to the operation instruction and contained in the preloading active window stack to the display screen for displaying. The method has the advantages that when the target application program really needs to be started, the drawn application interface is directly migrated to the display screen to be displayed, the application interface can be rapidly switched, and the starting speed is improved.

In some embodiments, the migrating an application interface corresponding to a target application program corresponding to the execution instruction, which is included in the preloaded active window stack, to the display screen for displaying includes: migrating a task stack corresponding to a target application program corresponding to the running instruction and contained in the preloading active window stack to the top of an application active window stack; and updating the size information, the configuration information and the visibility of the task stack to realize that the application interface corresponding to the target application program is displayed on the display screen. The advantage that sets up like this lies in, can guarantee the stability of interface migration process, guarantees that the card screen can not appear in the recovery process, the black screen or the migration speed is slow scheduling problem.

For some terminals, especially mobile terminals such as mobile phones and tablet computers, in order to facilitate the use of users, the display modes of the display screen generally include vertical screen display and horizontal screen display, many applications display by default in the vertical screen mode, some applications display by default in the horizontal screen mode (such as some network games), and some applications switch the horizontal and vertical screen display along with the direction in which the user holds the terminal during the use of the terminal. In some embodiments of the present application, a boundary coordinate corresponding to the preloaded active window stack is (H, 0, 2H, H), a coordinate system corresponding to the boundary coordinate is a system coordinate, an origin of the system coordinate is an upper left corner of the display screen, and H is a length of a long side of a display area of the display screen. That is, the side corresponding to H is the maximum side of the display area of the display screen, and is the height of the display screen in the vertical screen display and the width of the display screen in the horizontal screen display. This is done to allow for the display of a landscape screen, pre-loaded application landscape displays, and the normal display of some applications. Fig. 2 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present disclosure. As shown in fig. 2, at this time, the display screen is in a vertical screen mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 201, the width direction of the display screen 201 is the X axis, the height direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area. Fig. 3 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present application. As shown in fig. 3, at this time, the display screen is in a landscape mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 301, the height direction of the display screen 301 is the X axis, the width direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area.

The reason why the pre-loaded Stack boundaries are so set is that:

the abscissa of the upper left corner is H, which is an interface for preventing the display screen (also referred to as a main screen) from displaying the preloaded application during the landscape screen, and since the main screen has a landscape mode in addition to the portrait mode, the abscissa of the upper left corner of the rectangular area corresponding to the preloaded Stack is set to the screen height in order to prevent the main screen display area from displaying the local part of the preloaded application during the landscape screen of the main screen.

The ordinate in the upper left corner is 0 in order for the preload application to be able to calculate the status bar height correctly. In order to better design a User Interface (UI), the Android application can customize the top status bar, and if the vertical coordinate corresponding to the upper edge is not equal to 0, the height of the status bar may be wrong.

The abscissa of the lower right corner is 2H (2 times the screen height), that is, the width of the rectangle corresponding to the preloaded Stack is equal to the screen height, so that the size of the preloaded Stack can contain the landscape application at the time of preloading (that is, the application interface is an application program in a landscape display mode).

The ordinate of the lower right corner is H, i.e. the height of the rectangle corresponding to the preloaded Stack is equal to the screen height, so as to preload the size of the Stack and be able to contain the vertical screen application at the time of preloading.

For the reasons described above, the inventors set the size of the preload Stack to (H, 0, 2H, H).

In addition, fig. 4 is a schematic application interface migration diagram provided in the embodiment of the present application, as shown in fig. 4, when an operation instruction of a target application program is received, an application interface 401 corresponding to the target application program included in a preloaded active window Stack is migrated to a display screen 201 to be displayed, specifically, a task to which the preloaded application interface belongs is migrated to the top of an application active window Stack, and size information, configuration information, and visibility of the task are updated, so that the application interface can be normally displayed on the display screen.

And step 607, controlling the mobile terminal to enter a target desktop when the unlocking operation verification is detected to be successful.

It can be understood that the number of the applications included in the target desktop is limited, generally about 20, the target application can be predicted quickly by the prediction model, the target application can be predicted normally before the unlocking verification is successful, and the target application can be preloaded after the prediction is completed.
