[0031] In an embodiment, Figure 1 A flowchart of a file playing method provided by an embodiment of the present application, the embodiment can be applicable to the case of playing a file in a terminal device, the method can be executed by a file playing device, the file playing device can be realized in the form of hardware and / or software, and the file playing device can be configured in a client built in an electronic device. Illustratively, the client can be an independent application program (APP), or a third-party application applet attached to other APP. Illustratively, the electronic device can include but is not limited to a smart phone, an iPad, a computer and the like mobile terminal. As shown in the figure, the method includes: Figure 1

[0032] S110, selecting at least two file attribute information according to a target selection mode to generate a corresponding current file attribute information group.

[0033] The target selection mode can be understood as a mode of selecting file attribute information, which can be a random mode to select file attribute information, or a sequential mode to select file attribute information, and the embodiment does not limit the mode of selecting file attribute information.

[0034] ​In the embodiment, each file corresponds to corresponding file attribute information. It can be understood that each audio file, video file, and photo file of different types corresponds to corresponding file attribute information. The file attribute information corresponding to each file at least includes at least one of a file access path, a file name, a file type, and a file memory size. The file type can be an audio file, a video file, or a photo file, which is not limited in the embodiment.

[0035] In the embodiment, the current file attribute information group refers to a set of file attribute information composed of the selected file attribute information. Each current file attribute information group can include at least two file attribute information. Of course, the number of current file attribute information groups in the embodiment can be one group or multiple groups, for example, 5 groups, 10 groups, and the like. The number of current file attribute information groups is not limited in the embodiment. In order to facilitate the grouping of file attribute information and improve the grouping efficiency, the number of file attribute information included in each current file attribute information group can be the same.

[0036] In the embodiment, at least two file attribute information can be selected according to a target selection mode to generate a current file attribute information group composed of at least two file attribute information. Specifically, at least two file attribute information can be selected according to a random selection mode to generate a corresponding current file attribute information group. At least two file attribute information can also be selected according to a sequential selection mode to generate a corresponding current file attribute information group.

[0037] In an embodiment, the file attribute information at least includes one of the following: a file access path; a file name; a file type; and a file memory size.

[0038] The file type includes one of the following: an audio file; a video file; and a photo file.

[0039] The file access path refers to a storage path corresponding to each file. The file memory size can be understood as the memory size of the file.

[0040] In the embodiment, the file types corresponding to each file attribute information in the same file attribute information group can be the same or different. The file memory size is related to the file type. Generally, the video file has a larger file memory size than the audio file and the photo file, and the audio file has a larger file memory size than the photo file. For example, the file memory size of the audio file can be 36kb, 50kb, or 20M, 36M, etc.; the file memory size of the video file can be 100M, etc.; and the file memory size of the photo file can be 20kb, etc.

[0041] In the embodiment, in order to ensure that the download time of the to-be-played file corresponding to each file attribute information in the same file attribute information group is close, the file types in the same file attribute information group can be the same.

[0042] S120, pre-download and play the to-be-played file corresponding to the current file attribute information group; wherein the to-be-played file is one-to-one corresponding to the file attribute information.

[0043] The to-be-played file refers to the file ready to be played. It should be noted that the to-be-played file corresponding to the current file attribute information group is at least two, and each to-be-played file in the current file attribute information group has corresponding file attribute information, which can be understood as that the to-be-played file is one-to-one corresponding to the corresponding file attribute information.

[0044] In the embodiment, the execution order of pre-downloading and playing includes two implementation manners: one is to pre-download the to-be-played file while playing the to-be-played file that has been successfully downloaded; the other is to play the to-be-played file after completing the downloading of all to-be-played files.

[0045] Specifically, the to-be-played file can be played after the downloading of all to-be-played files corresponding to the current file attribute information group is completed; or the to-be-played file that has been successfully downloaded can be played during the pre-downloading of the to-be-played file corresponding to the current file attribute information group.

[0046] S130, in response to a file deletion operation, deleting the to-be-played file corresponding to the current file attribute information group, and taking the next file attribute information group as the current file attribute information group.

[0047] The file deletion operation can be understood as an operation of deleting the to-be-played file when the corresponding deletion trigger condition is met.

[0048] In an embodiment, the file deletion operation satisfies the following trigger condition: the to-be-played file corresponding to the current file attribute information group is played, and the to-be-played file corresponding to the next file attribute information group is pre-downloaded.

[0049] In the embodiment, when the to-be-played file corresponding to the current file attribute information group is played and the to-be-played file corresponding to the next file attribute information group is pre-downloaded, the to-be-played file corresponding to the current file attribute information group is deleted, the to-be-played file corresponding to the next file attribute information group is played, and the next file attribute information group is taken as the current file attribute information group. Then, the to-be-played file corresponding to the current file attribute information group is played until the to-be-played file corresponding to all file attribute information groups is played. It should be noted that, after the to-be-played file corresponding to the next file attribute information group is pre-downloaded and the play queue is switched to the to-be-played file corresponding to the new file attribute information group, the storage data in the storage card is deleted according to the file access path, the file name, the file type, and the like of the current file attribute information group, so that the current play is not affected, thereby ensuring the smoothness of the current play, and the problems of insufficient storage space and memory OOM caused by the limitation of the performance of the mobile device are avoided, and the operation is relatively stable.

[0050] The technical solution of the embodiment of the application can pre-download and play the to-be-played file corresponding to the current file attribute information group, delete the to-be-played file corresponding to the current file attribute information group in response to the file deletion operation, take the next file attribute information group as the current file attribute information group, and play the to-be-played file corresponding to the current file attribute information group until the to-be-played file corresponding to all file attribute information groups is played. Therefore, the problems of unable to download or memory OOM caused by insufficient storage space or insufficient memory space are solved, the to-be-played file is downloaded in groups, a large amount of memory resources is not occupied, the network resources are saved, and the operation is relatively stable.

[0051] In an embodiment, Figure 2 The flowchart of another file playing method provided by an embodiment of the application is based on the above embodiments and is further refined. In order to better understand the flow of the entire file playing method, the embodiment is described by taking the example of logging in and checking a username and a password first, then selecting a to-be-played file from a shareable file, and playing the to-be-played file. Figure 2 As shown in the figure, the file playing method in the embodiment can include the following steps.

[0052] S210, in response to the received login instruction, a communication connection is established with the associated network storage.

[0053] The login instruction refers to an instruction that a user inputs corresponding information by clicking or touching to log in. The network storage can also be referred to as network attached storage, and refers to a terminal device connected to a network and having a data storage function. It is a dedicated data storage server that is data-centric, completely separates storage devices from servers, centrally manages data, thereby releasing bandwidth, improving performance, reducing total cost of ownership, and protecting investment. Its cost is much lower than that of using server storage, and its efficiency is much higher than that of the latter. Exemplarily, the network storage can be a NAS device.

[0054] In this embodiment, the user can input corresponding Internet Protocol (IP), username, password, and verification code, and the like, to establish a communication connection with the associated network storage to perform relevant verification of the username and password. In an embodiment, the process of establishing a communication connection between the mobile terminal to which the client belongs (i.e., the client is installed on the mobile terminal) and the network storage can be understood as the process of establishing a communication connection between the mobile terminal and the network storage in the same local area network.

[0055] S220, in response to the verification success instruction, obtaining and displaying the shareable files from the network storage; wherein the to-be-played files are a subset of the shareable files.

[0056] The shareable files refer to files that can be shared with other access devices (such as mobile terminals) through a network. Exemplarily, the shareable files can include audio files, video files, and photo files, and the like. It should be noted that the to-be-played files are a subset of the shareable files, which can be understood as that the to-be-played files are obtained by selecting from the shareable files.

[0057] In this embodiment, after establishing a communication connection with the associated network storage according to the login instruction, the username and password are verified. In the case where the verification of the username and password is passed, in response to the verification success instruction, the corresponding shareable files are obtained and displayed from the network storage. It should be noted that when the verification of the username and password is performed, if the verification of the username and password fails, the IP, username, password, and verification code, and the like can be input again to perform the verification of the username and password until the verification is successful.

[0058] S230, in response to the received file selection instruction, obtaining file attribute information of the to-be-played file corresponding to the file selection instruction.

[0059] The file selection instruction refers to an operation of selecting a file by the user in a touch or click manner.

[0060] In the embodiment, on the interface of displaying the files, there is a corresponding option box on each file, and there is a corresponding full selection box for all files. The client receives the selection of files by the user through touch or click, of course, the user can select the files by touch or click, or can check the selected files by touch or click. For example, 10 photos are displayed on the display interface, the user can select all the 10 photo files at a time, or can check one photo file at a time, which is not limited in the embodiment.

[0061] In the embodiment, in the case of receiving the file selection instruction, the file attribute information of the to-be-played file corresponding to the file selection instruction is obtained. For example, the user selects 30 files by clicking, wherein the 30 files can include one or more of audio files, video files and photo files, and the file attribute information of the to-be-played file corresponding to each of the 30 files is obtained.

[0062] S240, store the file attribute information to the target memory space.

[0063] The target memory space refers to a storage space for storing the file attribute information of the to-be-played file. The target storage space is a running memory space, which can be a hash map (i.e. HashMap). It should be noted that the HashMap is a data structure commonly used in JAVA, which is composed of array + linked list + red-black tree combination. The data stored in the HashMap is stored in the memory, which can also be a hash table (i.e. Hashtable), which is not limited in the embodiment.

[0064] In the embodiment, the selected to-be-played file is traversed, and the file attribute information corresponding to the to-be-played file can be stored in the target memory space in the form of key-value pair. For example, the to-be-played file is 10 photo files, and the file attribute information corresponding to the 10 photo files, such as the access path, name and memory size of the 10 photo files, is stored in the target memory space. The to-be-played file is 3 photo files and 7 video files, and the file attribute information corresponding to the 3 photo files and 7 video files, such as the access path, name and memory size of the 3 photo files and 7 video files, is stored in the target memory space.

[0065] In an embodiment, storing the file attribute information to the target memory space comprises:

[0066] Storing the file attribute information to the target memory space in the form of key-value pair.

[0067] In the embodiment, the file attribute information of the to-be-played file can be stored in the target memory space in the form of key-value pairs.

[0068] It should be noted that in the key-value pairs, each key corresponds to a value, the key refers to the number of stored values, and the value refers to the data to be stored. In the embodiment, the file name and the file access path in the file attribute information can be used as a key, the file information corresponding to the to-be-played file, the file type corresponding to the to-be-played file, and the memory size occupied by the to-be-played file can be used as a value, and the corresponding file can be found according to the file name and the file access path.

[0069] S250, determining a target playing type according to the file attribute information of the to-be-played file and / or the association between the to-be-played files.

[0070] The target playing type refers to the type of content playing of the to-be-played file.

[0071] In some embodiments, the target playing type can include one of the following: sequential playing and random playing.

[0072] In the embodiment, the sequential playing can be playing in a regular order. For example, the to-be-played files can be played in the order of the memory size from small to large, or in the order of the shooting or recording time, or in the order of the successful downloading sequence. The embodiment does not limit this. When the random playing is used, the to-be-played files can be played according to a pre-configured random algorithm and a non-repeated playing strategy.

[0073] In the embodiment, the target playing type can be determined according to the file attribute information of the to-be-played file and / or the association between the to-be-played files. For example, when the to-be-played files are a set of photographed photos, the playing type of the photographed photos can be determined according to the file attribute information of each photo in the set of photographed photos and / or the association between the set of photographed photos, and the playing type of the photographed photos is determined to be playing the photo content in sequence.

[0074] S260, determining a target selection mode of the file attribute information according to the target playing type.

[0075] In the embodiment, the target selection manner of the file attribute information is determined according to the target play type of the to-be-played file. For example, if the target play type of the to-be-played file is random play, the target selection manner of the file attribute information can be to select the current file attribute information in random or in a certain order; if the target play type of the to-be-played file is sequential play, the target selection manner of the file attribute information is to select the current file attribute information in a certain order or in random.

[0076] S270, selecting at least two file attribute information according to the target selection manner to generate a corresponding current file attribute information group.

[0077] S280, pre-downloading and playing the to-be-played file corresponding to the current file attribute information group; wherein the to-be-played file and the file attribute information are one-to-one.

[0078] S290, in response to a file deletion operation, deleting the to-be-played file corresponding to the current file attribute information group, and taking the next file attribute information group as the current file attribute information group.

[0079] The above technical solution of the embodiment of the application can quickly and accurately determine the target play type according to the received login instruction, the verification success instruction, the file selection instruction, the file attribute information, the target memory space, the file attribute information, and the association between the to-be-played files, so that the user can select the corresponding target play type, and the user experience is improved to a certain extent.

[0080] In an embodiment, Figure 3 The flowchart of another file play method provided by the embodiment of the application is further refined on the basis of the above embodiments, for example, Figure 3 As shown in the figure, the file play method in the embodiment can include the following steps:

[0081] S310, selecting at least two file attribute information according to the target selection manner to generate a corresponding current file attribute information group.

[0082] In an implementation mode, S310 comprises S3101 or S3102.

[0083] S3101, selecting at least two file attribute information from the target memory space in a random selection manner to generate a corresponding current file attribute information group.

[0084] In the embodiment, at least two file attribute information can be selected from the target memory space in a random selection manner to generate a corresponding current file attribute information group. Of course, the random selection manner can be a manner that a user randomly selects at least two file attribute information according to needs, preferences or habits. For example, the user randomly selects the second, fourth and sixth file attribute information from the target memory space according to habits to generate a corresponding current file attribute information group containing three pictures.

[0085] S3102, selecting at least two file attribute information from the target memory space in a sequential selection manner to generate a corresponding current file attribute information group.

[0086] In the embodiment, at least two file attribute information can be selected from the target memory space in a sequential selection manner to generate a corresponding current file attribute information group. Of course, the sequential selection manner can be a manner that at least two file attribute information are sequentially selected according to the order of files, the size order of memory occupied by files, etc. For example, the first, second, … and tenth file attribute information are sequentially selected from the target memory space according to the order of files to generate a corresponding current file attribute information group containing ten pictures.

[0087] S320, pre-downloading a to-be-played file corresponding to the current file attribute information group.

[0088] In the embodiment, the current file attribute information group generated by the at least two file attribute information is obtained, and a download thread is started to download the current file attribute information group into the mobile terminal device.

[0089] S330, in response to that a pre-download duration reaches a preset duration threshold, playing the to-be-played file corresponding to the current file attribute information group according to a pre-determined target playing type.

[0090] In the embodiment, the preset duration threshold can be understood as a pre-set pre-download duration threshold. The preset duration threshold can be set according to user needs or according to experience, which is not limited in the embodiment. For example, the preset duration threshold can be 20s or 30s, which is not limited in the embodiment.

[0091] It should be noted that the preset duration threshold corresponding to the file type of the to-be-played file is different. Specifically, when the file type corresponding to the to-be-played file is a photo file, the corresponding preset duration threshold is relatively short, and when the file type corresponding to the to-be-played file is a video file and / or an audio file, the corresponding preset duration threshold is relatively long. For example, when 8 file attribute information corresponding to 8 photo files are included in the current file attribute information group, the preset duration threshold can be set to 15s; when 8 video files are included in the current file attribute information group, the preset duration threshold can be set to 1min, which is not limited in the embodiment.

[0092] In the embodiment, when the pre-download duration reaches the preset duration threshold, the to-be-played file corresponding to the current file attribute information group is played according to the predetermined target playing type. It should be noted that the to-be-played file in the embodiment is a file that has been downloaded within the pre-download duration. For example, the preset duration threshold is 25s, the to-be-played file corresponding to the current file attribute information group is a group of 10 pictures, and within 25s, the to-be-played file corresponding to the current file attribute information group that has been pre-downloaded is a group of 8 pictures. Then, the to-be-played file that has been downloaded is played according to the predetermined target playing type, which is a group of 8 pictures.

[0093] In an embodiment, in response to the pre-download duration reaching the preset duration threshold, the to-be-played file corresponding to the current file attribute information group is played according to the predetermined target playing type, comprising:

[0094] In response to the pre-download duration reaching the preset duration threshold, the to-be-played file corresponding to the current file attribute information group is played according to the predetermined target playing type; wherein the to-be-played file is a subset of the to-be-played file.

[0095] In the embodiment, when the pre-download duration reaches the preset duration threshold, the to-be-played file corresponding to the current file attribute information group is played according to the predetermined target playing type; wherein the to-be-played file is a subset of the to-be-played file, which can be understood as a part or all of the to-be-played file.

[0096] S340, downloading the to-be-played file to a preset storage space.

[0097] The preset storage space refers to the local memory corresponding to the mobile terminal, for example, the storage space corresponding to the SD card of the mobile terminal device.

[0098] In the embodiment, the to-be-played file is downloaded to the preset storage space to be saved in the preset storage space. It should be noted that the to-be-played file can be downloaded to the mobile terminal device for playing by using a supported shareable transmission protocol, for example, a file transfer protocol (FTP), a server message block (SMB), a network file system (NFS), or the like.

[0099] It should be noted that the to-be-played file in the embodiment is a downloaded to-be-played file. After the to-be-played file is downloaded to the preset storage space, the to-be-played file corresponding to the current file attribute information group is deleted from the preset storage space when the to-be-played file corresponding to the next file attribute information group is pre-downloaded.

[0100] S350, in response to the file deletion operation, deleting the to-be-played file corresponding to the current file attribute information group and taking the next file attribute information group as the current file attribute information group.

[0101] The above technical solution of the embodiment of the application can further solve the problem of unable to download or memory OOM caused by insufficient storage space or insufficient memory space, realize downloading of the to-be-played file in groups, do not occupy a large amount of memory resources, make the overall process smooth and interruptable at any time, save network resources, and make the operation more stable.

[0102] In an embodiment, in order to better understand the file playing method, the embodiment can be used as a preferred embodiment to further describe the file playing method. Figure 4A flow chart of another file playing method is provided in an embodiment of the present application. The embodiment takes a photo file as an example of file type, and takes sequentially selecting at least two file attribute information as an example of target selection mode, and is described in detail.
