The components of the memory 120, the processor 130, the communication unit 140, and the display unit 150 are electrically connected directly or indirectly to each other to implement data interaction. For example, the components can be electrically connected to one another via one or more communication buses or signal lines. The data synchronization device 110 includes at least one software function module that can be firmwareized in an operating system (OS) of the user terminal 100 in the form of software or firmware.

In this embodiment, the data synchronization device 110 may be a subroutine of the APP, or may be a program independent of the APP.

The memory 120 can be, but not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), and a Programmable Read-Only Memory (PROM). Erasable Programmable Read-Only Memory (EPROM), Electric Erasable Programmable Read-Only Memory (EEPROM), and the like.

The display unit 150 is configured to establish an interaction interface between the user terminal 100 and the user, or to display information to be displayed.

As shown in FIG. 3, it is a schematic flowchart of a data synchronization method according to an embodiment of the present invention. The data synchronization method is applied to the user terminal 100 shown in FIG. 2. The specific process and steps shown in Figure 2 will be detailed below. set forth.

Step S101: Acquire a first data list from the server 200, where the first data list includes identifier information of a plurality of data to be displayed.

The data to be displayed refers to data that the APP in the user terminal 100 needs to display, for example, sticker data, skin data, and the like.

Taking the live broadcast APP as an example, the server 200 corresponding to the live broadcast APP usually provides a plurality of sticker data for the user to select. When the user opens the live broadcast application at the user terminal 100, the user interface of the live broadcast APP displays an identifier (eg, a thumbnail, a name) of the plurality of sticker data. Assuming that the user selects one of the identifiers, the user terminal 100 detects whether the sticker data corresponding to the identifier has been downloaded, and if downloaded, directly retrieves from the local without having to request the sticker data from the server 200.

According to the research by the inventor, some existing methods are to detect whether there is a file name corresponding to the detected sticker data by scanning the file name in the local directory folder, and if so, determining that the detected sticker data has been Downloaded, otherwise it has not been downloaded.

However, this practice has drawbacks. On the one hand, if there is a duplicate sticker file in the downloaded sticker data stored locally, the above detection process cannot be realized. On the other hand, if the content of the same sticker file is changed, it cannot be detected only by the file name. In addition, downloaded local files are typically stored on disk, so traversing file names is essentially an IO operation. IO operations are a very slow process that will slow down the running of the app and affect the user experience.

The data synchronization method provided in this embodiment may be executed when the APP is started, or may be executed periodically during the running of the APP, which is not limited in this embodiment.

In implementation, the user terminal 100 sends a network 300 request (eg, an HTTP request) to the server 200, and the server 200 requests feedback to the user terminal 100 for the first data list for the network 300. The first data list includes identification information of a plurality of to-be-displayed data, where the identification information may include identity information and summary information of data to be displayed. The identity information may be an ID number, and the digest information may be digest information obtained by calculating the to-be-displayed data by a Message Digest Algorithm (MD5, MD5). The identification information is used to uniquely characterize data to be displayed.

Step S102: Create a data object including a data element and a status tag for each identification information in the first data list, store the identification information in the data element, and set the status flag to not download.

In this embodiment, the first data list returned by the server 200 does not include the data to be displayed, but includes the identification information of the data to be displayed. That is, each data to be displayed is in an undownloaded state. For each identification information in the first data list, a data object is created for the identification information, the data object includes a data element and a status tag, and the data element and the status tag are attributes of the data object. The identification information is stored in the data element of the data object created for the identification information, and the status flag attribute of each established data object is set to not downloaded.

Setting the status tag attribute to not download means that the value of the status tag attribute is set to indicate a value or a string that has not been downloaded. For example, 0, 1, available, etc. may be used to indicate that the download is not performed, and may be determined according to actual needs.

Still taking the sticker data as an example, for each identification information, the following data structure can be established:

Public class PatsrItem{

Private int type;

Private int status;

Private pasterResource prs;

}

That is, the data structure of each identification information in the first data list is processed. In the implementation, a sticker object PasterItem is created for each identification information in the first data list, wherein the pasterResource is a sticker element for storing the sticker data information returned by the server 200, that is, for storing the identification information or Data to be displayed. The type includes a type_stop, a type_setting, and a type_item, respectively corresponding to a stop button, a setting button, and a sticker element button on an application interface of the APP. The stop button is used to control the stop of downloading, the setting button is used to set the sticker, and the sticker element is used to represent the corresponding sticker data, which is usually displayed as a thumbnail or name corresponding to the sticker data.

In this embodiment, when the value of the type attribute is type_stop or type_setting, the values of other attributes may be null.

The status indicates a status flag of the current sticker. In this embodiment, the status may include the following options: STATUS_FINISH, STATUS_AVAILABLE, STATUS_RETRY, STATUS_DWONLOADING, etc., wherein STATUS_FINISH indicates that the download has been made, STATUS_AVAILABLE indicates that the download is not available (downloadable), and STATUS_RETRY indicates that Retry, STATUS_DWONLOADING indicates that the download is in progress.

Through the above processing, the obtained first data list is actually a list including a plurality of data objects, and the corresponding data to be displayed is not stored in each data object in the first data list, and the status tag attribute of each data object is Not downloaded.

Step S103, comparing the first data list with a second data list in the user terminal 100, where the second data list includes a data object that has been downloaded corresponding data to be displayed, and the downloaded to-be-displayed data is stored in the In the data element of a data object, the status of the data object is marked as downloaded.

The second data list is a list of data objects that have been downloaded before to be displayed. That is, the second data list includes a plurality of data objects, wherein the plurality of data objects store corresponding data to be displayed, and the status tag attributes of the plurality of data objects are all downloaded.

Taking the above sticker data as an example, the second data list includes a plurality of sticker objects, and the sticker elements of each sticker object store corresponding sticker data, and the status of each sticker object is marked as downloaded, wherein the state Marked as downloaded, the value corresponding to the status tag attribute is used to represent the downloaded value or string.

Optionally, in this embodiment, the step S103 can be implemented by the following steps:

In this embodiment, the identification information of the data to be displayed may include identity information and summary information of the data to be displayed. When the first data list is compared with the second data list, the first data list processed in step S102 is actually compared with the second data list.

Before the comparison, the first data list and the second data list that are usable need to be obtained. In detail, the second data list can be obtained by:

Obtaining the shared parameter object provided by the system of the user terminal 100 by calling the shared parameter acquisition instruction getSharedPreferences(), and acquiring the data object stored in the user terminal 100 by calling the information acquisition instruction getString() of the shared parameter object, Each data object adds a tag corresponding to the second data list, for example, labeled localPasterItem. The second data list can be obtained by calling the getPasterList() instruction of localPasterItem.

Correspondingly, each data object in the first data list may be marked as remoutPasterItem, and then The first data list can be obtained by calling the getPasterList() instruction of remoutPasterItem.

In the implementation, the for loop method may be used to traverse the first data list, take a data object in each loop body, and call the getid() instruction and the getMd5() instruction of the data object to obtain the identity information of the data object and The summary information is compared with the identity information and the summary information of each data object in the second data list to detect whether the data object having the same identity information and the summary information exists in the second data list. .

The manner of obtaining the identity information and the digest information of each data object in the second list is similar to the manner of obtaining the identity information and the digest information of each data object in the first data list.

Step S104: Synchronize the data objects included in the first data list in the second data list to the first data list according to the comparison result, obtain a target data list, and display the target data list. .

In this embodiment, the step S104 may have multiple implementation manners, for example, by implementing the following manners:

Establishing a target data list, for each data object in the first data list, if the data object is included in the second data list, adding the data object in the second data list to the In the target data list; if the data object is not included in the second data list, the data object in the first data list is added to the target data list.

For another example, the data object included in the first data list in the second data list may be directly synchronized into the first data list. For example, assuming that the data object X exists in the first data list, and the data object X is also found in the second data list by comparison, the data object X in the second data list is synchronized into the first data list, that is, The data object X in the first data list is overwritten with the data object X in the second data list. Thus, the finally obtained first data list is essentially equivalent to the target data list, and thus the processed first data list is the target data list.

In this embodiment, displaying the target data list means that the target data list is sent to an application interface of the APP for display.

Optionally, after the user terminal 100 displays the target data list, the method may further include step S105, step S106, and step S107.

Step S105, in response to the user selecting operation of each data object in the target data list, determining whether the data to be displayed corresponding to the data object has been downloaded according to the status flag of the selected data object. If yes, then Go to step S106; if no, go to step S107.

Step S106, displaying the data to be displayed stored in the data element of the data object.

Step S107, downloading data to be displayed corresponding to the data object from the server 200.

Through the above design, when the user performs the selection operation, the user can immediately and accurately know whether the selected data object is downloaded, and then perform corresponding operations, thereby improving the user experience.

Optionally, the method may further include the following steps:

After the data to be displayed corresponding to the data object is obtained from the server 200, the acquired data to be displayed is stored in a data element of the data object, and the status flag of the data object is set to be downloaded; the data object is Stored in the specified target file.

The step of storing the data object in the specified object file can be implemented as follows:

Calling the shared parameter acquisition instruction getsharedPreferences(), obtaining a storage path of the target file in the user terminal 100, and returning a shared parameter object including the storage path; calling an edit instruction Edit() of the shared parameter object to obtain An edit object for editing the target file; calling the data write instruction putString() of the edit object to write the data object in the form of a key value pair; calling the commit instruction commit() of the edit object to write the data The content written by the instruction putString() is submitted to the target file.

Among them, the shared parameter acquisition instruction getsharedPreferences() is an integrated instruction in the SharedPreferences utility class.
