In this embodiment, the APP can be the APP that has the image acquisition function such as live APP, the APP of making a video recording, the APP of shooing, also can be the APP of other information sets that need to show. The information set is a set of a plurality of categories of information.
In this embodiment, the user terminal 100 may be a Personal Computer (PC), a smart phone, a tablet Computer, a wearable mobile device, or the like. The user terminal 100 has installed therein an APP provided by the server 200. Optionally, the user terminal 100 may be a terminal device based on an Android system.
Fig. 2 is a block diagram of a user terminal 100 according to an embodiment of the present invention. The user terminal 100 includes a data synchronization apparatus 110, a memory 120, a processor 130, a communication unit 140, and a display unit 150.
The memory 120, the processor 130, the communication unit 140 and the display unit 150 are electrically connected to each other directly or indirectly to realize data interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The data synchronization device 110 includes at least one software function module that can be solidified in an Operating System (OS) of the user terminal 100 in the form of software or firmware (firmware).
In this embodiment, the data synchronization apparatus 110 may be a subroutine of the APP, or may be a program independent of the APP.
The Memory 120 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.

The display unit 150 is used for establishing an interactive interface between the user terminal 100 and a user, or for displaying information to be displayed.
Fig. 3 is a schematic flow chart of a data synchronization method according to an embodiment of the present invention, where the data synchronization method is applied to the user terminal 100 shown in fig. 2. The specific process and steps shown in fig. 2 will be described in detail below.
Step S101, a first data list is obtained from the server 200, where the first data list includes identification 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 a live APP as an example, the server 200 corresponding to the live APP will generally provide a plurality of sticker data for users to select. When the user opens the live APP at the user terminal 100, the identifiers (e.g., thumbnails, names) of the sticker data are displayed on the user interface of the live APP. 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 so, the sticker data is taken directly from the local without requesting the sticker data from the server 200.
The inventor researches and discovers that some existing methods are to judge whether a file name corresponding to the detected sticker data exists or not by scanning the file name in a local directory folder, and if so, the detected sticker data is determined to be downloaded, otherwise, the detected sticker data is not downloaded.
However, this approach has drawbacks. On one hand, if there is a duplicate name sticker file in the downloaded sticker data stored locally, the above-mentioned 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, and thus, traversing the file name is essentially an IO operation. IO operation is a very slow process, which will slow down the running speed of the APP, and further affect the user experience.
The data synchronization method provided in this embodiment may be executed when the APP is started, or may be periodically executed in the running process of the APP, which is not limited in this embodiment.
In practice, the ue 100 sends a network 300 request (e.g. HTTP request) to the server 200, and the server 200 feeds back the first data list to the ue 100 according to the network 300 request. The first data list includes identification information of a plurality of data to be displayed, where the identification information may include identity information and summary information of the data to be displayed. The identity information may be an ID number, and the summary information may be summary information obtained by calculating the data to be displayed by using a message summary Algorithm fifth edition (MessageDigest Algorithm MD5, MD 5). The identification information is used to uniquely characterize the data to be displayed.
Step S102, establishing a data object including a data element and a status flag for each identification information in the first data list, storing the identification information in the data element, and setting the status flag to be not downloaded.
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 un-downloaded state. And aiming at each identification information in the first data list, establishing a data object for the identification information, wherein the data object comprises a data element and a state mark, and the data element and the state mark are attributes of the data object. And storing the identification information into the data elements of the data objects established for the identification information, and setting the established state mark attribute of each data object as not downloaded.
The setting of the status flag attribute as not downloaded means that the value of the status flag attribute is set to a value or a character string used for representing not downloaded, for example, 0, 1, available, etc. may be used for representing not downloaded, and may be determined according to actual requirements.
Still taking the sticker data as an example, for each identification information, the following data structure may 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 implementation, a sticker object passitem is established for each piece of identification information in the first data list, where a passive resource is a sticker element and is used to store the sticker data information returned by the server 200, that is, to store the identification information or the data to be displayed. The type comprises type _ stop, type _ setting and type _ item, and the type _ stop, the type _ setting and the type _ item respectively correspond to a stop button, a setting button and a sticker element button on the application interface of the APP. The stop button is used for controlling to stop downloading, the setting button is used for setting the paster, and the paster element is used for representing corresponding paster data and is usually displayed as a thumbnail or a name and the like of the corresponding paster data.
In the present embodiment, when the value of the type attribute is type _ stop or type _ setting, the values of the other attributes may be null.
The STATUS indicates the STATUS flag of the current sticker, and in this embodiment, the STATUS may include the selection of STATUS _ FINISH, STATUS _ AVAI L AB L E, STATUS _ RETRY, STATUS _ DWON L pending, etc., where STATUS _ FINISH indicates downloaded, STATUS _ AVAI L AB L E indicates not downloaded (downloadable), STATUS _ RETRY indicates retriable, STATUS _ DWON L pending indicates downloading.
Through the above processing, the obtained first data list is actually a list including a plurality of data objects, and each data object in the first data list does not store corresponding data to be displayed, and the status flag 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 downloaded corresponding data to be displayed, the downloaded data to be displayed is stored in a data element of the data object, and a status of the data object is marked as downloaded.
The second data list is a list formed by data objects of the data to be displayed which are downloaded before. That is, the second data list includes a plurality of data objects, the data objects each store corresponding data to be displayed, and the status flag attributes of the data objects are all downloaded.
Taking the above-mentioned sticker data as an example, the second data list includes a plurality of sticker objects, the sticker element of each sticker object stores corresponding sticker data, and the status flag of each sticker object is downloaded, where the status flag is downloaded, which means that the value corresponding to the attribute of the status flag is a value or a character string used for characterizing that the downloaded value or character string is downloaded.
Optionally, in this embodiment, the step S103 may be implemented by:
and acquiring identity information and summary information in each data object in the first data list, and detecting whether the data objects with the same identity information and summary information exist in the second data list.
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 comparison, a first data list and a second data list which can be used need to be acquired, and in detail, the second data list can be acquired in the following manner:
the shared parameter object provided by the system of the user terminal 100 is obtained by calling the shared parameter obtaining instruction getSharedPreferences (), the data objects stored in the user terminal 100 are obtained by calling the information obtaining instruction getString () of the shared parameter object, and the second data list can be obtained by adding a mark corresponding to the second data list to each obtained data object, for example, the mark is localPasterItem, and then calling the getpointer L ist () instruction of the localPasterItem.
Accordingly, each data object in the first data list may be marked as a remoutPasterItem, and the first data list may be obtained by calling a getMaster L ist () instruction of the remoutPasterItem.
In implementation, a for-loop method may be adopted to traverse the first data list, take one data object in each loop, call the getid () instruction and getMd5() instruction of the data object to obtain the identity information and the digest information of the data object, and compare the identity information and the digest information with the identity information and the digest information of each data object in the second data list to detect whether a data object with the same identity information and digest information exists in the second data list.
The manner of obtaining the identity information and the summary information of each data object in the second list is similar to the manner of obtaining the identity information and the summary information of each data object in the first data list.
And step S104, synchronizing the data objects included in the first data list in the second data list into the first data list according to the comparison result to obtain a target data list, and displaying the target data list.
In this embodiment, the step S104 may be implemented in various manners, for example, by:
establishing a target data list, and if the second data list comprises the data object, adding the data object in the second data list to the target data list aiming at each data object in the first data list; and if the second data list does not comprise the data object, adding the data object in the first data list into 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 to the first data list. For example, assuming that there is a data object X in the first data list, and the comparison shows that there is also a data object X in the second data list, 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 covered by the data object X in the second data list. In this way, the finally obtained first data list is substantially identical 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 refers to sending the target data list to an application interface of the APP for displaying.
Optionally, after the user terminal 100 presents the target data list, the method may further include step S105, step S106, and step S107.
Step S105, responding to the selection operation of the user on each data object in the target data list, and 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, go to step S106; if not, step S107 is executed.
And step S106, displaying the data to be displayed stored in the data element of the data object.
Step S107, downloading the data to be displayed corresponding to the data object from the server 200.
Through the design, after the user executes the selection operation, whether the selected data object is downloaded or not can be immediately and accurately known, and then the corresponding operation is executed, so that the user experience is improved.
Optionally, the method may further comprise the steps of:
after the data to be displayed corresponding to the data object is acquired from the server 200, the acquired data to be displayed is stored in the data element of the data object, and the status flag of the data object is set to be downloaded; and storing the data object into a specified target file.
The step of storing the data object into the specified target file can be realized by the following steps:
calling a shared parameter acquisition instruction getsharedPreferences (), acquiring 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 acquire an Edit object for editing the target file; calling a data writing instruction putString () of the editing object to write the data object in a key value pair mode; and calling a commit command commit () of the editing object, and committing the content written by the data writing command putString () to the target file.
Wherein the shared parameter get instruction getsharedPreferences () is an integrated instruction in the SharedPreferences tool class.
