Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

First embodiment

Referring to fig. 1, a method for optimizing cold start of an application according to a first embodiment of the present invention is shown, where the method includes:

step S10: when cold starting is carried out on a target application, a preview window of the target application is created;

step S20: detecting whether a preset first interface picture exists in a preset storage area or not, wherein the first interface picture is the same as an application main interface of the target application;

step S30: if the first interface picture exists, displaying the first interface picture in the preview window;

step S40: after the application main interface is loaded, switching the preview window into the application main interface;

step S50: screenshot is conducted on the application main interface, and a second interface picture is obtained;

step S60: and updating the first interface picture in the preset storage area into the second interface picture.

In step S10, the target application may be any system or application installed in any terminal device, and the system may be an Android system, an IOS system, or the like. The terminal device may be a smart phone, a tablet computer, a smart television, and the like, without limitation.

The manner in which the target application is triggered to start includes, but is not limited to, the following: after clicking the icon of the target application by the user, starting the target application; and the user triggers the starting of the target application in other associated applications. In this embodiment, the starting of the target application is cold starting. In cold start, generally, since the background service does not have a process related to the target application, or the target application is started for the first time, the system needs to re-create and allocate a corresponding process for initialization.

And a Preview window (Preview window), which is a window displayed in advance in order to prevent the display of the main interface from being too slow when the application is in cold start, so as to prompt a user that the application is being loaded and displayed and avoid mistakenly considering that the application is blocked and falsely killed. Taking the android system as an example, in specific implementation, the system server may be requested to create previwindow when the application is cold-started. When creating the preview window, it should also check whether the current target application meets the creation condition, that is, the specific steps before creating the preview window are as follows:

step S11: and judging whether the application main interface to be loaded by the target application is a transparent window or a floating window. When the application main interface preloaded by the target application is a transparent window, the interface displayed on the terminal device and capable of being viewed by the user may be interfaces of other applications, wallpaper and the like which cannot be determined. When the application main interface is the floating window, the position of the floating window on the screen is uncertain, and other contents can be displayed on the screen except the floating window. In the above two cases, it is not certain when the screenshot of the application main interface is performed, and if the screenshot of the application main interface is performed in the above case, it is difficult to achieve the effect of seamless switching, because it is difficult to determine what content is being displayed on the current screen when the user triggers the start of the target application.

Step S12: and if the application main interface is not a transparent window or a floating window, creating a preview window of the target application.

Step S20: detecting whether a preset first interface picture exists in a preset storage area, wherein the first interface picture is the same as an application main interface of the target application.

In step S20, for convenience of management, the preset storage location may be a location under the installation path of the target application, or any other location in the memory, without limitation.

In this embodiment, the preset first interface picture may be obtained in the following manner:

1. when the target application is installed, a main interface picture of the target application is stored as a first interface picture by default. For example, since the main interface of a general application program is mostly the same when the application program is started for the first time after installation, an initial main interface picture can be stored as the first interface picture when a developer develops the application. Thereafter, each time the application is started, the application main interface is subjected to screenshot under the condition that the screenshot condition is satisfied to update the first main interface picture, and the following descriptions of steps S30-S60 may be specifically referred to.

2. The first interface picture is a picture generated by screenshot when the target application is cold started last time. This manner of acquiring the first interface picture is equivalent to steps S30-S50.

Step S30: and if the first interface picture exists, displaying the first interface picture in the preview window.

In step S30, the display of the first interface picture is temporary, and at this time, due to the display of the first interface picture, the preloading of the target application is achieved, and the user can click on the first interface picture again. Therefore, the situation that the user mistakenly thinks that the target application is blocked and falsely killed due to the fact that the default preview window is directly displayed can be avoided, and further the situation that the user performs operations of returning, main menus, shutdown and the like which increase the cost of the processor is avoided.

in step S40, since the application main interface is the same as the first interface picture, after the application main interface is loaded, the application main interface can be directly displayed in the foreground, and the seamless switching between the application main interface and the first interface picture can be completed. At this time, the preview window can be closed to avoid occupying too much content or consuming processor resources.

Further, in some cases, the application main interface may change with the use of the user during the use of the target application by the user. For example, the layout of the application main interface changes, the display content of the application main interface changes, the icons of the application main interface changes, the size of the characters changes, and the like. Therefore, the first interface picture needs to be updated, i.e., steps S50-S60.

in step S50, the present embodiment provides two embodiments.

1. And carrying out single screenshot when the target application is started to obtain a second interface picture. The method comprises the following specific steps:

step S501: and judging whether the starting time of the application main interface is a specific moment. The specific time is the time when the main interface of the target application is just loaded, namely the time when the starting time is started and timed just when the target application is started and finished. In this embodiment, the time when the main interface of the target application is started is 0. In addition, whether the mobile phone is in a vertical screen or horizontal screen state can be judged, the target application is started in a vertical screen mode when being started, and the screenshot can be carried out when the current screen state is in the vertical screen mode; when the target application is started, the screen is horizontally started, and the screenshot can be performed when the current screen state is horizontally judged.

Step S502: and if the starting time of the application main interface is the specific moment, screenshot is carried out on the application main interface to obtain the second interface picture. At this time, the application main interface is not operated by the user and is not changed. The second interface picture obtained after the screenshot is carried out on the application main interface at the moment is completely the same as the specific moment of the application main interface, and the seamless switching between the application main interface and the interface picture is favorably realized. If the target application can be started in a horizontal screen state and a vertical screen state, the finally obtained second interface picture can correspondingly mark the horizontal screen state or the vertical screen state, namely, the second interface picture is divided into a horizontal screen state group and a vertical screen state group which respectively correspond to the horizontal screen start and the vertical screen start.

Step S503: and if the starting time of the application main interface is not the specific moment, not performing screenshot.

Taking the android system as an example, in specific implementation, when the screenshot condition is met, the App Transition Server service in the system can be requested to perform screenshot operation.

2. And performing multiple screenshots when the target application is started to obtain a second interface picture. The method comprises the following specific steps:

step S511: when the target application displays an application main interface, screenshot is carried out on the application main interface in the sliding process of the application main interface, and a plurality of temporary pictures are obtained.

In step S511, since the application main interface cannot be fully displayed on the display screen of the current electronic device, for example, the application main interface may be slid up and down and/or left and right. Therefore, when the screenshot is carried out, a plurality of pictures can be intercepted on the application main interface in the process of user operation and sliding. Specific rules can be referred to as follows:

the method can be used for capturing one picture at a specific moment when the target application is loaded, and capturing the picture once when the user slides the application main interface up and down and/or left and right to exceed half of the width of the application main interface in the current direction. Then, when the user slides to the boundary position of the application main interface, the screenshot is performed. Therefore, the application main interface can be completely intercepted as much as possible.

Step S512: splicing the plurality of temporary pictures to obtain a second interface picture; and the second interface picture comprises all display contents of an application main interface of the target application.

In step S512, the captured images are spliced to form a complete application main interface image. If the user does not browse the application main interface completely in the operation process, the part which is not intercepted can be supplemented directly by using the default picture of the application main interface, and the default picture of the application main interface is a picture preset by an application developer when developing the target application, such as a complete long screenshot carried out on the application main interface; in addition, when the first interface picture exists, the first interface picture can be adopted to complement the part of the application main interface which is currently intercepted.

When the preview window displays the second interface picture obtained through steps S511-S512, the user may directly perform a sliding operation on the second interface picture. Application preloading is more complete, and the interaction experience between a user and a target application being loaded is improved.

In step S60, the updating mode may be an overlay updating, the first interface picture is deleted, the second interface picture is saved, and the processor overhead is saved. In addition, image comparison can also be carried out, if the second interface picture is changed relative to the first interface picture, reading and writing operation is carried out, the first interface picture is deleted, and the second interface picture is stored; and if the second interface picture is not changed relative to the first interface picture, the first interface picture is reserved.

Corresponding to step S30, if there is no cached first interface picture in the preset storage location, creating the preview window and displaying a default configured preview window, displaying a default interface in the preview window, and after the target application is loaded, switching the preview window to the application main interface; then, the following steps are carried out: screenshot is conducted on the application main interface, and a third interface picture is obtained; and saving the third interface picture into the preset storage area.

Further, in this embodiment, in order to further improve the utilization efficiency and performance of the target application in the loading process, the following implementation steps may be added:

step S71: and recording the click position of the user for displaying the first interface picture.

In step S71, a click event of the user clicking the screen may be obtained through the code, and a click position and a click time at which the click event occurs are recorded, which corresponds to the user actually operating on the application main interface of the target application.

Step S72: and after the displayed preview window of the first interface picture is switched to the application main interface, carrying out simulated click on the application main interface according to the click position.

In step S72, the operation of the application main interface may include various situations, such as: after the application main interface is clicked, the application main interface is converted into a submenu of the clicked icon or title; there may also be multiple selection operations on the application main interface (no change in the interface menu occurs, only certain titles or icons are selected). Therefore, the following steps can be executed when the application main interface is clicked in a simulation mode:

step S721: clicking the application main interface according to the time sequence corresponding to the clicking position;

step S722: and stopping the simulated click when the simulated click reaches the option containing the submenu or the interface jump transformation.

In this embodiment, the interaction efficiency between the user and the target application can be further improved through steps S71-S72, the target application can be substantially operated in the target application loading process, the use efficiency of the target application is improved, the meaningless operation caused by mistakenly considering that the target application is stuck or falsely killed by the user is avoided, and the resource overhead of the processor is saved.

It should be noted that the functions of each step in the present invention can be implemented by using corresponding codes, and the specific codes can be written and implemented by those skilled in the art after understanding the execution logic of the present invention, and different development codes correspond to different system platforms, and the process of implementing the codes is not described again.

Referring to fig. 2, in the android system, it is found that, in the same configuration and under the same working condition, a camera program which is not subjected to preview optimization and is subjected to preview optimization by using the optimization method for application cold start provided by the present invention is tested: because the screenshot is loaded in the preview window for preview optimization, the application main interface can be quickly displayed, and the meaningless operation of the user is avoided. The result shows that although the operation step of displaying the interface picture to the preview window is added, the loading speed is improved and the time is saved on the whole.

In summary, in the optimization method for application cold start provided in the embodiment of the present invention, when a target application is triggered to start, a preview window of the target application is created; checking whether a preset first interface picture exists in a preset storage position or not; if the cached first interface picture exists in the preset storage position, displaying the first interface picture to the preview window to replace a default interface; the first interface picture is the same as an application main interface of the target application; therefore, in the process of loading the target application, the user can preview the application main interface of the target application in advance and can consider the operation on the target application in advance. Further, after the application main interface is loaded, switching the displayed preview window of the first interface picture to the application main interface; because the display content of the application main interface is the same as that of the first interface picture, a user cannot perceive the display content during switching, and seamless switching is realized. After switching is completed and loading of the target application is completed, screenshot is conducted on the application main interface to obtain a second interface picture, the first interface picture in the preset storage position is updated to the second interface picture, updating of pictures needing to be displayed on the preview window is achieved, and displaying of different or wrong interface pictures on the preview window after the application main interface is changed is avoided. Because the interface picture which is the same as the main application interface can be displayed in the process of loading the target application every time, the phenomenon that a user mistakenly thinks that the target application is blocked or falsely died is avoided, the meaningless operations of switching the application, returning to a desktop, shutting down and the like which are performed after mistaken recognition are also avoided, the waste of processor resources under the meaningless operations is avoided, and the use performance of the equipment can be indirectly improved; meanwhile, the content of the application main interface can be displayed when the preview window is created, so that the loading efficiency of part of the content of the target application is improved; because the user can see the content of the application main interface at the first time, the interactive experience of the target application and the user and the use efficiency of the target application are improved.
