Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a solution for inaccurate data in multimedia databases. Background Technology

[0002] The Android system now stores media resources (music, video, images, etc.) directly in a multimedia database. When we need to manipulate media resources (such as searching, filtering, displaying, etc.), we can directly operate on the associated multimedia database. This is more convenient, faster, and requires lower performance while being more efficient. To import media resource information into the multimedia database, simply send a fixed system broadcast to scan the specified path.

[0003] This solution works fine under normal use. However, if the user uses the local file renaming function provided by the device to change the name of a folder in the path where the media resources are stored to an easy-to-remember and distinguishable name, the media database will have problems after rescanning: (1) After the file or folder is renamed, it will not continue to scan downwards, so the original media resource information in the multimedia database will not be updated; (2) After the file is rescanned, the new media information will be written to the multimedia database, but the original media data information before the renaming will not disappear and will still be stored in the multimedia database, causing data chaos and inaccuracy. Summary of the Invention

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0056] The Android system now stores media resources (music, video, images, etc.) directly in a multimedia database. When we need to manipulate media resources (such as searching, filtering, displaying, etc.), we can directly operate on the associated multimedia database. This is more convenient, faster, and requires lower performance while being more efficient. How do we import media resource-related data into the multimedia database? Simply send a fixed system broadcast to scan the specified path.

[0057] This solution works fine under normal use. However, if the user uses the local file renaming function provided by the device to change the name of a folder in the path where the media resources are stored to an easy-to-remember and distinguishable name, the media database will have problems after rescanning: (1) After the file or folder is renamed, it will not continue to scan downwards, so the original media resource information in the multimedia database will not be updated; (2) After the file is rescanned, the new media information will be written to the multimedia database, but the original media data information before the renaming will not disappear and will still be stored in the multimedia database, causing data chaos and inaccuracy.

[0058] Based on this, this application provides a solution to the problem of inaccurate data in a multimedia database, which can effectively process redundant data in the database after the name is changed, thereby ensuring the accuracy of the data stored in the database.

[0059] Please see Figure 1 , Figure 1 This is a flowchart illustrating a solution for inaccurate data in a multimedia database, provided as an embodiment of this application. Figure 1 As shown in the embodiments of this application, the solution provided includes:

[0060] S101. In response to the renaming instruction, modify the original name of the target data according to the specified name carried in the renaming instruction.

[0061] Here, the renaming instruction is an instruction issued by the user through the renaming device.

[0062] The original name of the target data is modified according to the specified name carried in the renaming instruction, that is: the original name of the target data is replaced with the specified name carried in the renaming instruction.

[0063] The target data is a target file or a target folder.

[0064] For example, assuming the target data is a folder stored in the media folder on an SD card, and the original name of the target data is "AA" and the specified name is "Music", then modifying the original name of the target data according to the specified name carried in the renaming instruction means changing the name of the folder (target data) to "Music".

[0065] In one embodiment provided in this application, after modifying the original name of the target data according to the specified name carried in the renaming instruction, the solution further includes: packaging and storing the original name and the specified name of the target data in a specified area.

[0066] Here, both the original name and the specified name of the target data are preserved.

[0067] The specified area is a specific location in the Android multimedia database.

[0068] It's important to note that in Android systems, renaming and deleting old data from the database cannot be performed simultaneously; they must be done in a specific order. If the corresponding data is deleted before renaming, Android will try to locate the file based on its path in the database. If the file still exists, the system will delete it, causing the subsequent renaming to fail because the file no longer exists. Therefore, deleting database data must be done after renaming. Furthermore, after renaming the target data, when scanning or searching for that data, it will be added back to the database. However, the original data from before the renaming will not disappear and will remain stored in the multimedia database, causing data inconsistencies and errors. Therefore, it is necessary to delete this redundant data.

[0069] S102. Obtain the new storage path for the modified target data.

[0070] Here, based on the storage location of the target data and the modified name (specified name) of the target data, the new storage path of the modified target data is determined and retrieved.

[0071] Continuing with the example in step S101, it can be seen from S101 that the old storage path of the target data is sdcard / media / AA, and after the renaming operation, the new storage path of the target data is sdcard / media / music.

[0072] S103. In response to the traversal instruction, perform a data traversal operation according to the new storage path to determine at least one first storage path corresponding to the target data.

[0073] Here, the traversal instructions include instructions for traversing the target data and may also include instructions for traversing the subordinate data of the target data. The first storage path is a new storage path for the target data, or may also include storage paths for the subordinate data included in the target data.

[0074] During the traversal operation, the target data is typically stored again in the database, which is an Android multimedia database.

[0075] It should be noted that after renaming the target data, simply rescanning the path of the target data is not enough, because it will not scan downwards (for example, if there is a folder named media under the path / sdcard / , when we want to scan the resources under the path / sdcard / , the resources in / sdcard / media / will not be scanned, that is, it only scans the resources under the specified path, and the resources in the folders under the specified path will not be scanned), thus causing the original media resource information in the multimedia database to not be updated.

[0076] In another embodiment provided in this application, before responding to the traversal instruction, the solution further includes: identifying the attribute information of the target data to determine whether the type of the target data is a folder; if yes, issuing a traversal instruction to traverse the target data and its subordinate data; if no, issuing a traversal instruction to traverse the target data.

[0077] In another embodiment provided in this application, the step of responding to a traversal instruction and performing a data traversal operation based on the new storage path to determine at least one first storage path corresponding to the target data includes: performing a data traversal operation based on the new storage path to determine whether the target data includes at least one sub-data; if yes, obtaining the storage path of each sub-data, and determining the new storage path of the target data and the storage path of each sub-data as the first storage path to obtain at least one first storage path corresponding to the target data; if no, determining the new storage path of the target data as the first storage path.

[0078] For example, the process of determining at least one first storage path is illustrated below. Assume the target data is a file, stored at the media location on the SD card, the original name of the target data is "N", the specified name is "image", and the new storage path of the target data is "sdcard / media / image". In this case, the traversal instruction is a traversal instruction that only traverses the target data. Thus, only one first storage path can be determined, which is "sdcard / media / image".

[0079] Assuming the target data is a folder stored in the media folder on an SD card, with the original name "AA" and the specified name "Music," the target data includes a file (named BB) and a folder (named CC). The folder also contains two files, DD and EE. The traversal command then iterates over the target data and its subfolders. The resulting first storage paths include: "sdcard / media / images," "sdcard / media / images / BB," "sdcard / media / images / CC," "sdcard / media / images / CC / DD," and "sdcard / media / images / CC / EE."

[0080] S104. Obtain at least one second storage path based on the at least one first storage path and the original name of the target data.

[0081] Here, based on the at least one first storage path and the original name of the target data, a new and old name replacement operation is used to obtain at least one second storage path.

[0082] In one embodiment provided in this application, obtaining at least one second storage path based on the at least one first storage path and the original name of the target data includes: for each first storage path, identifying the target location of a specified name of the target data in the first storage path; and, based on the identified target location, performing a field replacement operation on the specified name in the first storage path using the original name of the target data to obtain at least one second storage path.

[0083] Continuing with the example in step S103, the process of determining at least one second storage path is described below. Assume the target data is a file, stored at the media location on the SD card, the original name of the target data is "N", and the specified name is "image". The determined first storage path is "sdcard / media / image". Replacing the original name with the specified name, the resulting second storage path is "sdcard / media / N".

[0084] Assuming the target data is a folder stored in the media folder on an SD card, with the original name "AA" and the specified name "Music," the target data includes one file (named BB) and one folder (named CC). The folder also contains two files: DD and EE. The determined first storage paths include: "sdcard / media / pictures," "sdcard / media / pictures / BB," "sdcard / media / pictures / CC," "sdcard / media / pictures / CC / DD," and "sdcard / media / pictures / CC / EE." Replacing the original name with the specified name yields the following second storage paths: "sdcard / media / AA," "sdcard / media / AA / BB," "sdcard / media / AA / CC," "sdcard / media / AA / CC / DD," and "sdcard / media / AA / CC / EE."

[0085] S105. For each second storage path, perform a data search in the database based on the second storage path, and delete the searched data.

[0086] Here, the second storage path is actually the original storage path of the target data. The database can be an Android multimedia database.

[0087] In this way, by restoring the original path (second storage path) of the target data, and comparing and searching in the multimedia database through the second storage path, the corresponding data saved in this path is considered junk information and is deleted, thereby ensuring data accuracy.

[0088] This application provides a solution for inaccurate data in a multimedia database, comprising: in response to a renaming instruction, modifying the original name of target data according to a specified name carried in the renaming instruction; obtaining a new storage path for the modified target data; in response to a traversal instruction, performing a data traversal operation according to the new storage path to determine at least one first storage path corresponding to the target data; obtaining at least one second storage path according to the at least one first storage path and the original name of the target data; for each second storage path, performing a data search in the database according to the second storage path, and deleting the searched data.

[0089] In this way, the technical solution provided in this application restores the old path by retaining both the old and new names and then replacing the new name field with the old name field. This allows us to find and process the corresponding garbage data using the old path. A loop is used to iterate through the data to be processed, preventing any omissions.
