See the status of the program running in the background, and display all the running programs in this way; when the user selects a task thumbnail, activate the corresponding background application to run; also can be touched by the screen Instead of keystrokes, manipulate the task thumbnails of these programs.

The multi-task management method based on the android system of the present invention, as shown in FIG. 1 and FIG. 2, is a schematic diagram of a multi-task management system architecture based on the android system according to the present invention. The android system includes the following management module: a task scheduling module. Status tracking module, window management module, state switching management module and gesture management module.

Task scheduling module: Through this module, the android system can only break through the existing technical state that only one task is running by default, and the other tasks in the multi-task are in the suspended state in the background, and are modified to switch to the multi-task management system. After that, multiple tasks can be run at the same time. In the multi-task management function of the prior art android system, in order to save system resources, the system will suspend the non-current running program. When the data is suspended, the system will use resources such as CPU and memory. Released for use by the currently running application, the method of the present invention utilizes the task scheduling module to enable multiple tasks of the system to run simultaneously, and the non-currently running application maintains the running state in the background under the management of the task scheduling module.

Status tracking module: This module is mainly responsible for the maintenance of the status in the multi-task management system. The status includes: multi-task operation status maintenance; multi-tasking window display status maintenance; gesture operation status maintenance.

Gesture management module: a gesture operation instruction for receiving a touch screen.

State switching management module: In order to make the multitasking management system more friendly in terms of state switching, the method of the present invention designs a corresponding animation display effect according to different state transitions.

Windows Management Module: This module is mainly responsible for the display view management of the running program in the background. The design idea is to divide the display area in the multi-tasking management system into the following areas:

1. Main desktop display area: After entering the multi-tasking management system in the method of the present invention, the main desktop has no major changes in functions, mainly presents all application icons installed in the current system, and can perform paging management on these icons. In the multitasking management system, the main desktop and the multitasking window display area are related in display, that is, when the multitasking window display area is displayed, the main desktop display area is slid out due to the appearance of the multitasking window display area. The screen display area, especially into the multitasking window display area - small thumbnail display status.

As shown in FIG. 3, it is a main desktop display effect diagram of the present invention, which includes a status bar and all application prompt bars installed in the system, and corresponding program thumbnails of multiple applications; one or some applications are in At runtime, the corresponding application is running in the background, and the last interface is displayed as a thumbnail icon, ie a task thumbnail, and the application name, ie title, is indicated below the task thumbnail. A search bar is set at the bottom of the screen for searching for multitasking.

2, multitasking window display area

After entering the multi-tasking management system, different display states will be entered according to the operation mode. For the convenience of the user to browse, the task thumbnails can set thumbnails of tasks with different sizes. Therefore, the display state can be a small task thumbnail. status. If there is no running application in the background of the system, the running multi-tasking thumbnail window will not be displayed. At this time, the main desktop view is in full-screen display state by default. At this time, the task thumbnail under the status bar is empty, and the effect is as shown in the figure. 3; but if there is a running program in the background, it will display the multitasking window being executed by default, and the main desktop is below the multitasking window display area. The effect is shown in Figure 4, which is displayed in the multitasking window. The effect of the small thumbnail display; among them, the multitasking thumbnail and the corresponding title being executed are displayed below the status bar, and the task thumbnail of the background application and its corresponding title are displayed in all applications.

In the state shown in FIG. 4, the multi-task management method based on the android system of the present invention can complete the display and hiding of the multi-tasking window by sliding the touch gesture. In the multi-task window hiding process, the main desktop will gradually upward. Slide vertically until the screen is covered, forming a view as shown in Figure 3. During the multitasking window display, the main desktop will gradually slide down vertically until the thumbnails of all tasks in the multitasking window being executed are displayed completely. Each application will correspond to a small task thumbnail. The small task thumbnail structure is shown in Figure 5. It consists of the following image: the last frame of the application, which forms the task thumbnail; the application is marked below the task thumbnail. The corresponding name.

When a small task thumbnail is selected (ie, enters focus state), an "X" button for closing the program appears on the right side of the title bar. Clicking on the title bar will respond to the close application operation. The "X" button does not appear on the title bar of the unselected task thumbnail. Clicking on the title bar at this time will not respond to closing the application operation. After clicking on a small task thumbnail, the corresponding task thumbnail is enlarged to full screen, and the application corresponding to the selected task thumbnail is activated and the corresponding task is executed, and then the multitasking management system interface is exited.

Large task thumbnail status: If there is a running application currently, the operation of the touch gesture will enter the thumbnail state, and the main desktop will not be displayed at this time. The actual effect diagram is shown in Figure 6. Multi-tasking window enters the rendering of the large task thumbnail display; you can see that the task thumbnail of an application fills the entire screen, and by sliding the left and right operations, you can choose to display the previous or next adjacent application task. Thumbnail and switch to the application task corresponding to the selected task thumbnail. When there is no operation, the selected task thumbnail will automatically zoom to full screen and exit the multitasking management system.

The multitasking management system and method of the present invention mainly accomplish the following technical features and benefits:

1. Intervention for the task scheduling mechanism of the android system: The prior art android system supports multi-tasking management, but the multi-task management mode is not that all open programs are in the running state at the same time, and the system only triggers on the top of the display interface. The program displayed is running, other programs are running but paused; after this state, the display interface will not be refreshed, the system message will not be received, but once triggered, the corresponding interface will be displayed. It's much faster than turning it back on. The multi-task management system of the present invention needs to run the application running in the background, instead of being in a pause state, so the state transition of the background task needs to be interfered, and the task scheduling module and the state tracking module of the present invention complete the background. Run the program's state reset and recovery to achieve multiple tasks that can run simultaneously.

2. Intervention for the window management mechanism of the android system: According to the description of the preferred embodiment above, it can be known that if the system of the present invention supports multitasking, each program running in the background is in a running state, and each program is triggered at this time. Draw and refresh the display interface; the android system in the prior art only supports refreshing the program interface running on the top layer, and the interface refreshing of multiple running programs requires intervention of the display scheduling of the system itself through the window management module, and the method and system of the present invention It is also necessary to ensure that the last frame of the thumbnail image of these programs is cached when all programs running in the background are not running, so as to provide operational materials for subsequent animation management modules and gesture management modules. There are two types of modules for saving thumbnail images. One is that the thumbnail images are all retained, and only one is active, and the others are paused, so other applications only display the task thumbnail image of the last frame. The other is that all tasks retain only one frame of thumbnail image, and the purpose of ensuring one frame of image is to make the application in a visual state of multitasking management.

In summary, the android system-based multitasking management method and system thereof implement multiple tasks simultaneously, and display corresponding task thumbnails on the interface to visually display all the tasks being executed and suspended, and finally pass the last A frame of interface image is displayed as a thumbnail of the task, which facilitates the user's intuitive browsing and selection of tasks.

It is to be understood that those skilled in the art will be able to make modifications and changes in accordance with the above description, and all such modifications and variations are intended to be included within the scope of the appended claims.
