After the switching application operation is completed, the data cached by the application switched to the background is saved to the router storage module communicatively connected with the terminal, for other applications to locally switch from the router to the data cached by the application in the background, and You don't have to go back to the application server or download it on the internet. Effectively avoiding the existing sharing of download data in the application switching process, the user needs to re-download the data that has been downloaded by other applications, so that the utilization of the terminal memory space is poor. Provides a way to increase the utilization of the terminal memory space without re-downloading the data that has been downloaded by other applications.

Because the existing sharing of the download data cannot be realized in the application switching process, the user needs to re-download the data that has been downloaded through other applications, so that the utilization of the terminal memory space is poor.

Based on the above problems, the present invention provides a storage control method for applying cache data.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a storage control method for applying cache data according to the present invention.

In an embodiment, the storage control method of the application cache data includes:

Step S10, when detecting a terminal-based application switching instruction, switching instructions according to the application Completing the application switching operation, acquiring an application running in the background of the terminal after marking the application switching operation, and marking the application as the first application;

In this embodiment, the user can load the application based on the terminal, for example, the loaded application is exemplified by QQ music, cool dog music, and iQiyi video client. When users need to listen to music, they can open QQ music or cool dog music to select music downloads. After the download is completed, they can be played locally in the terminal or played directly online. When the user is not sure which application to play music, the user will open the music application one by one. For example, first open the QQ music app and then open the cool dog music, or open the cool dog music and then open the QQ music, switch between different music applications; after opening a music application, select music based on the open music application Play, whether you choose to play online or select to play after downloading, you need to buffer the selected music and then play it. Of course, you can play while buffering. After the user selects different music for playing through different music applications. When detecting a terminal-based application switching instruction, switching between different applications, after running an application in the foreground to reach a preset time (for example, 5 minutes or 10 minutes, etc.), determining that the user selects the preset time The application is used to complete the required function, and after the application switching operation is completed, the application running in the background of the terminal is obtained and the application is marked as the first application, that is, the application that is switched to the background after the application switching instruction is acquired, For example, the currently running application is QQ music, and the application running in the background is cool dog music. After switching instructions, the QQ music is switched to run in the background, the cool dog music is run on the front end, and the cool dog music is run in the front end. The preset time determines that the QQ music is the first application.

In step S20, when the first application is a preset type application, extracting data cached by the first application;

After the first application is obtained, it is determined whether the first application is a preset type application, and the preset type includes, but is not limited to, an application that can share the same cache data, such as a music type and a video type. For example, when the first application is a QQ music application, the first application is determined to be a preset type application, and the specific process is: obtaining the name of the application by using the root package name query table 1, and the terminal according to the read package name and the application. The name together identifies whether the application is a preset type related application. When the first application is a preset type application, the data cached by the first application is extracted, for example, the song A downloaded by the QQ application when the front end is running is extracted. In an embodiment of the present invention, different identifiers may be set for each application, the identifiers including portions for distinguishing different applications and portions for distinguishing different types, for example, the identifiers included include symbols and digital portions, The symbol portion is used to distinguish the application, and the data portion is used to distinguish the type. Of course, under the understanding of those skilled in the art, other The manner in which the application is identified is also included within the scope of the present invention. The terminal may identify whether the application is a preset type of application based on an identifier of each application. The manner of determining whether the application is a preset type application may also include other technical solutions known to those skilled in the art, and details are not described herein again.

Table 1

Step S30, saving the cached data to a router storage module that is communicatively connected to the terminal, to directly access the file storage module of the first application when the application running in the foreground requests the file data that is loaded by the first application. Extracting the file data.

After extracting the data buffered by the first application, sending the cached data to a router storage module communicatively connected to the terminal, the router storage module saves the cached data, and The saved cache data sets identification information, and the identification information includes application information, data information, time information, and the like. When the cache data saved by the router is requested by the application running in the foreground of the terminal to request the same file data, the file data is directly extracted from the router storage module without being downloaded to the corresponding server or webpage, that is, it is not repeated. Downloading the downloaded file data saves the storage space of the terminal, thereby improving the utilization of the terminal storage space.

In an embodiment of the present invention, when a plurality of applications are running in the background, the data cached by the application that has the largest memory space is extracted and saved to the router storage module. Preferably, a storage space threshold stored in the storage module of the router may be set, and when the data cached by the application reaches the storage space threshold, the data cached by the application larger than the storage space threshold is saved to the router storage module. The storage space threshold may be 2 MB or 1 MB, etc. according to user requirements and/or storage space settings of the router storage module.

In other embodiments of the present invention, data stored in the router storage module is managed to ensure that there is sufficient storage space to store the latest data, and the data storage time reaches a certain time (7 days or 10 days, etc.). Deleting data whose storage time reaches a certain time; or deleting data whose usage count is less than the preset number of thresholds when the number of times the data is used is less than a preset number of thresholds (for example, 2 or 3 times, etc.). The above-mentioned manners are only for illustrative purposes, and are not limited to the above-described manners, and the technical solutions within the scope of the present invention are all within the scope of protection of the embodiments of the present invention, and will not be further described herein.

In this embodiment, after the switching application operation is completed, the data cached by the application switched to the background is saved in the router storage module that is connected to the terminal for communication, and the other application is switched from the local download of the router to the background application cached. Data without having to go back to the application server or download it on the internet. Effectively avoiding the existing sharing of download data in the application switching process, the user needs to re-download the data that has been downloaded by other applications, so that the utilization of the terminal memory space is poor. Provides a way to increase the utilization of the terminal memory space without re-downloading the data that has been downloaded by other applications.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a second embodiment of a storage control method for applying cache data according to the present invention. The first embodiment of the storage control method based on the foregoing application cache data, after the step S10, further includes:

Step S40, acquiring an application running in the foreground of the terminal after completing the application switching operation, and marking the application as the second application;

Step S50, when the second application is a preset type application, reading a maximum value of memory occupied by each application of the terminal;

Step S60: The memory space of the terminal is evenly allocated according to the read maximum value into a memory area corresponding to the number of applications, so that each application stores corresponding data.

In this embodiment, after the handover operation is completed, an application running in the foreground of the terminal after completing the application switching operation is acquired and the application is marked as the second application. Determining whether the second application is a preset type of application. The determining process is the same as the process of determining whether the first application is a preset type application in the foregoing first embodiment, and details are not described herein again. When the second application is a preset type application, the maximum value of the memory occupied by each application of the terminal is read. The memory space of the terminal is evenly distributed according to the read maximum value into a memory area corresponding to the number of applications, so that each application stores corresponding data.

In this embodiment, when the preset type is applied in the foreground of the terminal, the memory storage space of the terminal is evenly distributed, and the running speed of the terminal is improved.

Referring to FIG. 3, FIG. 3 is a schematic flowchart diagram of a third embodiment of a storage control method for applying cache data according to the present invention. The second embodiment of the storage control method based on the application cache data, after the step S30, further includes:

Step S70, filtering cached data of an application running in the background for more than a preset time;

In step S80, the cached data is deleted, and all applications running in the background are closed.

In this embodiment, after the data cached by the application running in the background is saved in the router memory, the application running in the background for more than the preset time is filtered, and the cached data loaded by the application exceeding the preset time is filtered. Delete the cached data and close all applications running in the background. The preset time is preferably 5 minutes, or may be 10 minutes after 8 minutes, and the like. After the terminal is shut down, the application running in the background is longer than the preset time, the data cached by the application whose running time is greater than the preset time is automatically cleared, and other applications are stopped in the background, and the terminal releases the data cached in the background to reduce the occupation of the terminal. The memory storage space provides more memory for the application running in the foreground, thereby avoiding the problem of running the application in the foreground, and improving the running speed and efficiency of the terminal. In an embodiment of the present invention, referring to FIG. 4, after step S80, the method further includes: step S90, acquiring identification information of the closed application, and displaying the identification information on an interface of the current foreground running application. The terminal is displayed in the upper left corner of the foreground application according to the closed background application name, and the display application name in the background is in the upper right corner, and the displayed position is not limited to the upper left corner or the upper right corner according to the user setting, according to each user's Habits are different and set in different locations. In other embodiments of the present invention, the value of the storage space occupied by the data stored in the storage module of the router may be determined; and the value of the occupied storage space is displayed on the interface of the current foreground running application.

For a better description of the embodiments of the present invention, referring to FIG. 5, including:

Process 1: Start (System TV receives commands to switch between two media music applications, such as: switching between QQ music and cool dog music, the system issues an interrupt character command, 0x100 represents command switching.)

Process 2: The TV system starts the media application name module, the system obtains the name of the media application through the root package name lookup table, and the TV system reads the package name and the media name to distinguish (determine whether each application is a media application) whether the two applications are Media related applications? For example, the package name of the media application name module in Table 1 corresponds to the name of the media application, Media_Name(x1)=com.ttl.qqmusic (QQ music);

Media_Name(x2)=com.kugo.music (cool dog music)

Media_Name(x2)=com.iqyi.music (singular music)

Process 3: Does the TV system find two music applications? For example: QQ music, cool dog music application, two cases: a situation, TV system found that the current front and back are two media applications, such as: Media_Name (x1) = com.ttl.qqmusic (QQ music)

Media_Name(x2)=com.kugo.music (cool dog music)

Process 7: The TV system finds that the application is not in the front and back, not the two media, and the system closes the background identity module before the media application. For example: Media_Name(x1)=com.ttl.qqmusic(QQ Music)

Media_Name(x2)=com.kugo.TT (Cool Dog Magazine);

Process 4: In one case, the TV system finds that the application is currently in the front and back, which is two media applications.

The system starts the background application module before the media application, and the system determines whether the current application is in the foreground or the background through the media receiving the key event, the application receiving the key event is the foreground application, the other is the background application, 1, the foreground, 0, the logo background, for example. : Cool dog music: Media_Identity_Mode(x2)=0;

Process 5: Does the TV system find that the foreground application is a music application? For example: QQ music: Media_Identity_Mode (x1) = 1, two cases: one case: TV system found that the foreground application is a music application, such as: QQ music: Media_Identity_Mode (x1) = 1, another case: TV system found the foreground The application is not a music application, such as: Media_Name(x2)=com.kugo.TT (Cool Dog Magazine), Media_Identity_Mode(x2)=0;

Process 6: A situation: the TV system finds that the foreground application is a music application, and the TV system finds that the package name (QQ music) of the media application foreground identity module is a foreground application, and the system starts to apply the dynamic memory. The detection module, the system reads the maximum value of each application memory, and averages the memory according to multiple applications in the entire memory area of the TV system, for example, inputting two applications are QQ music, cool dog music, and the total memory of the TV system is 512MB, the average memory of the foreground application is 256MB;

Number of applications entered: Input_num_ap(x1)=2

Total memory of TV system: TV_RAM(x1)=256M

Apply average memory total:

TV_AVE_RAM=TV_RAM(x1)/Input_num_ap(x1)=256/2=256M.

specific:

1, the system obtains the size of the application's own memory space,

For example: QQ music memory needs up to 50MB.

Cool dog music memory needs up to 1000MB. If it is larger than the size required by the application, it will be wasted to be allocated to QQ and cool dog applications.

2. The system obtains the total size of the physical memory space, dynamically averages the number of video applications, and the system obtains the average allocated memory size, for example, multiple QQ music applications, a total of 10

TV_AVE_RAM=TV_RAM(x1)/Input_num_ap(x1)=512/10=51MB.

3. The system compares the value of the physically allocated memory application with the memory size of the application itself. The physical application space is larger than the application memory space, and the system sets the maximum memory size for the application. For example: QQ music memory needs up to 50MB, allocate 51MB in time, and finally, set QQ music physical memory 50MB.

Process 8: Another situation: The TV system finds that the foreground application is not a music application, the TV system finds the music (cool dog music) application as a background application, the system starts the memory transfer router module, and the system reads the value of the application dynamic memory detection module. After one-half of the download data is downloaded from the background application, the data downloaded from the background is transferred to the router storage area 33. The system is timed for 5 minutes, and the router memory space can only store the memory of the longest and largest saved data at the back end time. For example: 512MB of routing storage control, 5 minutes to, the router saves 3 songs of cool dog music application, love you for 10,000 years, ice rain, heart only you, MP3 music data is temporarily stored in the router, router discovers TV system There are other media applications in the background. The router sends a memory data command to stop receiving applications, and does not receive data from other applications. The router also sends instructions to stop other applications to the TV.

Process 9: The TV system opens the route to close the background application module, the routing system automatically closes the application whose background running time is greater than 5 minutes, the data stored in the TV terminal is cleared, the other background applications are stopped, and the TV system releases the data cached in the background. For example: the TV system receives the routing command, stops Stop running thousands of listening applications, emptying cached MP3 and other music data.

Process 10: The TV system opens a reminder to the background media display module. The TV system displays the name of the background application in the upper left corner of the foreground application according to the closed background application name, and displays the name of the application running in the background in the upper right corner, indicating the size of the cache to the router. For example: display off thousands of listening music, show cool dog music cache to the router 3 songs, love you for 10,000 years, ice rain, heart only you.

The execution subject of the storage control method of the application cache data of each of the above embodiments may be a terminal. Further, the storage control method of the purifier application cache data may be implemented by a storage control program of a client application cache data installed on the terminal, wherein the terminal includes but is not limited to a smart TV, a mobile phone, a pad, a notebook computer, etc. Preferably, it is a smart TV.

For a better description of the embodiments of the present invention, referring to FIG. 5, including:

Process 1: Start (System TV receives commands to switch between two media music applications, such as: switching between QQ music and cool dog music, the system issues an interrupt character command, 0x100 represents command switching.)

Process 2: The TV system starts the media application name module, the system obtains the name of the media application through the root package name lookup table, and the TV system reads the package name and the media name to distinguish (determine whether each application is a media application) whether the two applications are Media related applications? For example, the package name of the media application name module in Table 1 corresponds to the name of the media application, Media_Name(x1)=com.ttl.qqmusic (QQ music);

Media_Name(x2)=com.kugo.music (cool dog music)

Media_Name(x2)=com.iqyi.music (singular music)

Process 3: Does the TV system find two music applications? For example: QQ music, cool dog music application, two cases: a situation, TV system found that the current front and back are two media applications, such as: Media_Name (x1) = com.ttl.qqmusic (QQ music)

Media_Name(x2)=com.kugo.music (cool dog music)

Process 7: Another situation: The TV system finds that the application is not in the front and back, not the two media, and the system closes the background identity module before the media application. For example: Media_Name(x1)=com.ttl.qqmusic(QQ Music)

Media_Name(x2)=com.kugo.TT (Cool Dog Magazine);

Process 4: In one case, the TV system finds that the application is currently in the front and back, which is two media applications.

The system starts the background application module before the media application, and the system determines whether the current application is in the foreground or the background through the media receiving the key event, the application receiving the key event is the foreground application, the other is the background application, 1, the foreground, 0, the logo background, for example. : Cool dog music: Media_Identity_Mode(x2)=0;

Process 5: Does the TV system find that the foreground application is a music application? For example: QQ music: Media_Identity_Mode (x1) = 1, two cases: one case: TV system found that the foreground application is a music application, such as: QQ music: Media_Identity_Mode (x1) = 1, another case: TV system found the foreground The application is not a music application, such as: Media_Name(x2)=com.kugo.TT (Cool Dog Magazine), Media_Identity_Mode(x2)=0;

Process 6: A situation: the TV system finds that the foreground application is a music application, and the TV system finds that the package name (QQ music) of the media application foreground identity module is a foreground application, and the system starts to apply the dynamic memory detection module, and the system reads each application memory. The maximum value, compared with the entire memory area of the TV system, the average of the memory according to multiple applications, for example: input 2 applications are QQ music, cool dog music, the total memory of the TV system is 512MB, and the average memory of the foreground application is 256MB. ;

Number of applications entered: Input_num_ap(x1)=2

Total memory of TV system: TV_RAM(x1)=256M

Apply average memory total:

TV_AVE_RAM=TV_RAM(x1)/Input_num_ap(x1)=256/2=256M.

specific:

1, the system obtains the size of the application's own memory space,

For example: QQ music memory needs up to 50MB.

Cool dog music memory needs up to 1000MB. If it is larger than the size required by the application, it will be wasted to be allocated to QQ and cool dog applications.

2. The system obtains the total size of the physical memory space, dynamically averages the number of video applications, and the system obtains the average allocated memory size, for example, multiple QQ music applications, a total of 10

TV_AVE_RAM=TV_RAM(x1)/Input_num_ap(x1)=512/10=51MB.

3. The system compares the value of the physically allocated memory application with the memory size of the application itself. The physical application space is larger than the application memory space, and the system sets the maximum memory size for the application. For example: QQ music memory needs up to 50MB, allocate 51MB in time, and finally, set QQ music physical memory 50MB.

Process 8: Another situation: The TV system finds that the foreground application is not a music application, the TV system finds the music (cool dog music) application as a background application, the system starts the memory transfer router module, and the system reads the value of the application dynamic memory detection module. After one-half of the download data is downloaded from the background application, the data downloaded from the background is transferred to the router storage area 33. The system is timed for 5 minutes, and the router memory space can only store the memory of the longest and largest saved data at the back end time. For example: 512MB of routing storage control, 5 minutes to, the router saves 3 songs of cool dog music application, love you for 10,000 years, ice rain, heart only you, MP3 music data is temporarily stored in the router, router discovers TV system There are other media applications in the background. The router sends a memory data command to stop receiving applications, and does not receive data from other applications. The router also sends instructions to stop other applications to the TV.

Process nine: the TV system opens the route to close the background application module, and the routing system automatically forwards the background. The application with the line time greater than 5 minutes is closed, the data stored in the TV terminal is cleared, and other background applications are stopped. The TV system releases the data cached in the background. For example, the TV system receives the routing command and stops running the application of thousands of listeners. , clear the cached MP3 and other music data.

Process 10: The TV system opens a reminder to the background media display module. The TV system displays the name of the background application in the upper left corner of the foreground application according to the closed background application name, and displays the name of the application running in the background in the upper right corner, indicating the size of the cache to the router. For example: display off thousands of listening music, show cool dog music cache to the router 3 songs, love you for 10,000 years, ice rain, heart only you.
