For example, touch operations applied to different applications (such as taking pictures, playing audio, etc.) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects for touch operations acting on different areas of the display screen 194 . Different application scenarios (for example: time reminder, receiving information, alarm clock, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The indicator 192 can be an indicator light, and can be used to indicate charging status, power change, and can also be used to indicate messages, missed calls, notifications, and the like.

The operating system of the electronic device may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. In this embodiment of the present application, the Android system with layered architecture is taken as an example to illustrate the software structure of the electronic device.

FIG. 2 is a block diagram of a software structure of an electronic device according to an embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

The application layer can consist of a series of application packages. As shown in Figure 2, the application package may include applications such as camera, gallery, calendar, call, map, navigation, setting, Bluetooth, music, video, and short message.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions. As shown in Figure 2, the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, etc., upgrade management module, storage management interface, power management interface, traffic management interface.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide communication functions of electronic devices. For example, the management of call status (including connected, hung up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the status bar at the top of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, issuing a prompt sound, vibrating the electronic device, and flashing the indicator light, etc.

The upgrade management module is mainly used to detect the upgrade dynamics of the application, and can detect in time when an application is upgraded, and notify the notification manager of the application upgrade message.

The storage management interface is used to transmit the data of the application software so as to store the data when the application software is backed up, upgraded or downloaded.

The power management interface is connected with the power driver to complete the power consumption monitoring of electronic equipment related applications.

The traffic management interface is connected with the protocol driver, and is used to complete the monitoring of the traffic usage of related applications of electronic equipment.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, a sensor driver, a protocol driver, a power driver, and a storage driver.

Referring to FIG. 3 , FIG. 3 is a schematic diagram of an interface of a user using a display screen of an electronic device provided in an embodiment of the present application.

The user can click the "Settings" icon 301 in FIG. 3 to open the setting interface. The schematic diagram of the setting interface is shown in interface A in FIG. 4, which is a schematic diagram of an application version backup function interface provided by the embodiment of the present application.

The user can click the "application version backup" option shown in interface A in Figure 4, and then jump to a configuration interface, that is, interface B. The user can long press the button of an application in interface B, and three function buttons will pop up, namely "Restore", "Add", and "Delete"; the user can click the "Restore" option to restore the application to the saved version , the operation interface is as shown in interface A and interface B in FIG. 5; FIG. 5 is a schematic diagram of an operation interface of a recovery application version provided by an embodiment of the present application.

The user clicks the "Add" option to replace the currently saved version data of an application with the version data of other applications; for example, the user chooses to replace the version data saved by application A with a certain version data of application D. As shown in interface B and interface C in FIG. 6 , FIG. 6 is a schematic diagram of an operation interface for adding an application version provided by an embodiment of the present application. The user selects application D, and clicks the OK button to complete the adding operation.

The user clicks the "Delete" option to delete the application version data saved by the current application; the operation interface is shown in interface A and interface B in Figure 7, and Figure 7 is a schematic diagram of an operation interface for deleting an application version provided by the embodiment of this application. After the user clicks the delete button and confirms, the application is deleted and the default icon style is displayed, for example, an icon showing "Please add an application".

In this embodiment of the application, in the "App Version Backup" option in the "Settings" application, the number of applications that can be set for application version backup can be the system default number, and user-defined is also supported. For example, the default number of applications that can perform application version backup is 3, and the user can set the number according to the size of the actual memory of the electronic device. The number of application version backups is limited, so that version backups can be performed for some applications, avoiding version backups for all applications, and reducing unnecessary memory space occupation.

Referring to FIG. 8, FIG. 8 is a flow chart of backing up an application version provided by an embodiment of the present application.

First of all, set the "application version backup" function in the "settings" application. Generally, when the electronic device leaves the factory, the "application version backup" setting is performed on the "settings" interface. For example, the number of supported applications that can be backed up can be set to three.

Then the user makes specific settings for the "application version backup" function. For example, the user can customize the number of applications that can perform version backup according to the actual memory size of the electronic device, for example, the number is set to 5. The user can also select a specific application on the "application version backup" option interface, for example, the user sets application A as an application that can perform version backup.

The system side detects in real time whether the application to be upgraded performs version upgrade operation. If it detects that the application to be upgraded performs the version upgrade operation, a notification of the detected application upgrade is sent for subsequent pop-up operations to prompt the user whether to perform application version data update. backup operation.

When the system side detects that an application to be upgraded needs to be upgraded, the system side will detect whether the application backup space is full. If the application backup space is full, no pop-up operation will be performed, and the user will not be prompted whether to upgrade the application. The operation of backing up version data directly enters the step of ending the backup. If the system side detects that the application backup space is not fully occupied, then the system side will filter the applications according to the power consumption and traffic conditions of each application within the preset time period, and filter out the applications within the preset time period. Several applications that use a lot of power and traffic, that is, applications whose usage frequency exceeds a preset frequency standard within a preset time period. Judging whether the application to be upgraded is an application whose use frequency exceeds the preset frequency standard within a preset time period, and if so, the system side performs a pop-up window operation to prompt the user whether to backup the version data of the application before the upgrade; If not, then do not perform the pop-up operation, and directly enter the step of the end of the backup. After a pop-up window pops up to prompt the user, if the user chooses to back up the application version data, the system will save the version data of the application before the upgrade to the preset directory. When the user opens the "App Version Backup" interface in the "Settings" application, the specific version number of the backup will be displayed in this interface. So far, the application version backup is complete.

By calculating the power and traffic usage of each application within the preset time period, it is judged whether the application is an application whose usage frequency exceeds the preset frequency standard within the preset time period, that is, a commonly used application. If the application to be upgraded is If the application is frequently used, the application can be backed up; if the application is not a frequently used application, the version backup of the application can not be performed, so as to avoid unnecessary occupation of memory space.

In addition, if the application to be upgraded is determined by the system as not a commonly used application, when the application is upgraded, the pop-up operation will not be performed. If the user wants to back up the version of the application, he can go to the " The application version backup" option interface performs the operation of adding the application, and the processor responds to the instruction of adding the current version data of the application to the backup storage space, and backs up the current version data of the application.

In some possible implementation manners, the method for determining the preset time period may be implemented in the following manner:

Read the last time when the application to be upgraded is detected, and record it as the first time; read the time when the application to be upgraded is detected this time, and record it as the second time; determine the time period from the first time to the second time for the preset time period.

In some possible implementation manners, when there is no application to be upgraded, the user can also perform a version backup operation on the application. In order to distinguish it from the application to be upgraded, the application is represented as the first application. Specifically, the user can manually add the first application to the interface of "application version backup" in "settings", and the system side will back up the current version data of the first application.

Referring to FIG. 9 , FIG. 9 is another flow chart for backing up an application version provided by an embodiment of the present application.

The main difference between FIG. 9 and FIG. 8 is that when the system side detects that an application is being upgraded, the operation process of whether to perform version backup for the upgraded application is different.

The implementation process of the first two steps is the same as that of the previous embodiment, and will not be repeated here. The system side detects in real time whether there is an application to be upgraded. If it is detected that the application to be upgraded is about to undergo a version upgrade operation, a notification of the detected application upgrade is sent for subsequent pop-up operations to prompt the user whether to upgrade the application version before Data backup operations.

Then the system side will filter the applications according to the power consumption and traffic usage of each application within the preset time period, and select several applications that use more power and traffic during the preset time period. That is, applications whose usage frequency exceeds a preset frequency standard within a preset time period. If the application to be upgraded is an application whose usage frequency exceeds the preset frequency standard within a preset time period, the system side performs a pop-up window operation to prompt the user whether to backup the version data of the application before the upgrade. Users can choose whether to back up the application to be upgraded according to actual needs.

If the user chooses to back up the version data of the application to be upgraded, the system will detect whether the application backup space is full. Replace the data stored in the application backup space with the version data of the application to be upgraded before the upgrade; or prompt the user whether to increase the application backup space. After the user increases the application backup space, store the version data of the application to be upgraded before the upgrade to the added application in the backup space.

If the system side detects that the application backup space is not full, the system side will save the version data of the application before the upgrade to a preset directory. When the user opens the "App Version Backup" interface in the "Settings" application, the specific version number of the backup will be displayed in this interface. So far, the application version backup is complete.

Referring to FIG. 10 , FIG. 10 is a flow chart of screening commonly used applications provided by an embodiment of the present application.

The system detects in real time whether there is an application to be upgraded, and when there is an application to be upgraded that is about to be upgraded, an application version backup notification is triggered.

Then the system side reads the time of the last application upgrade notification and the time of this application upgrade notification, and obtains a preset time. The system side calculates the comprehensive usage value of the flow and power of each application within the preset time period; and sorts the applications according to the order of the comprehensive usage value from large to small; any one of the applications, the application undergoing version upgrade is determined as an application whose use frequency exceeds the preset frequency standard within a preset time period, that is, a commonly used application. The preset quantity can be flexibly set according to the actual situation. The specific implementation process is as follows:

The system side sorts each application according to the numerical value of traffic used by each application within a preset time period. Specifically, the system side will normalize the traffic value used by each application in MB. For example, if an application uses 1.2G, the value obtained after normalization processing is 1200. Use this rule to calculate the traffic value of each application. The numerical value of the flow rate used during the preset time period. Then, according to the obtained traffic values used by each application, the applications are arranged in descending order of the values, and then the applications with the top N traffic usage values are selected. The number of specific filters is set according to the number of version backups performed by supported applications in the "Settings" application. For example, the "Settings" application supports N applications for version backup. In this embodiment, if N is set to a value of 5, the applications with the top 5 traffic values are filtered out. For example, the top 5 applications are application A, application B, application C. Application D and application E respectively correspond to flow values a1, b1, c1, d1 and e1.

The system side sorts each application according to the value of power consumption of each application within a preset time period. Specifically, the system will normalize the power value used by each application in minutes. For example, if an application has been used for 2 hours, the normalized value will be 120. The amount of power used by the app over a preset period of time. Then, according to the obtained electric power values used by each application, arrange them in descending order of the numerical values, and then select the applications with the highest electric power usage values. Similarly, the number of specific screenings is set according to the number of version backups performed by the supported applications in the "Settings" application. For example, the "Settings" application supports 5 applications for version backup, and the applications with the top 5 battery values are filtered out. For example, the top 5 applications of the screened power values are application A, application D, application F, application C and application G in sequence, and the corresponding power values are a2, b2, c2, d2 and e2 respectively.

On the system side, the traffic values of the first five applications screened out are weighted, that is, the traffic values used by application A, application B, application C, application D, and application E are multiplied by a weighted value of 0.5 to obtain new values, which are 0.5 respectively a1, 0.5b1, 0.5c1, 0.5d1 and 0.5e1. Similarly, the system side weights the power values of the first five applications screened out, that is, the power values used by application A, application D, application F, application C, and application G are multiplied by a weighted value of 0.5 to obtain a new value. 0.5a2, 0.5b2, 0.5c2, 0.5d2 and 0.5e2 respectively.

Then, the weighted value of the traffic value used by each application and the weighted value of the power value are added to obtain the comprehensive usage value of the traffic and power of each application within a preset time period. Select the top 5 applications as frequently used applications according to the added value. The specific calculation process is as follows:

When the application B among the top 5 applications in the flow value is not the top 5 application in the power consumption value, assign the power value of application B to 0 and perform the addition operation; similarly, the application F and the application in the top 5 applications in the power consumption value G is not the application with the top 5 traffic usage values, and the traffic usage values of these two applications are assigned a value of 0 for addition. In this way, the traffic value and power value used by the application are multiplied by the weighted value in order to screen out commonly used applications by comprehensively considering the traffic usage and power usage of the application.

Referring to FIG. 11 , FIG. 11 is a flow chart of restoring an application version provided by an embodiment of the present application.

The user opens the "Settings" app, and in the "App Version Backup" function interface of the "Settings" app, finds the app that wants to restore the version. For example, select app A and want to restore the version, long press the option box of app A, and a For the "Restore" option, click the "Restore" button, and the system will analyze the version data saved in the preset directory, delete the current application version, and restore the saved version.

After the system side restores the saved version successfully, it notifies the user that the version data is successfully restored, and the reminder operation can be performed in the form of a bullet box or the like. At this point, the process of restoring the version is over.
