Referring to fig. 1, fig. 1 is a flowchart of a file scanning method according to an embodiment of the invention.
Referring to fig. 1, in an embodiment of the present invention, a file scanning method includes:
s101: and scanning files stored in the intelligent television through the JNI interface.
JNI is an abbreviation of Java Native Interface, and by writing a program using a Java native interface, it can be ensured that code is convenient to migrate on different platforms. Starting from Java1.1, the JNI standard becomes part of the Java platform, which allows Java code to interact with code written in other languages. That is, the JNI interface can implement interaction between java code and code written in other languages, and is generally used to implement java code and code constructed based on c++ language, and interact with code constructed based on C language. Accordingly, in the embodiment of the invention, the smart television is generally a smart television with an Android system.
S102: and when the scanned file is a folder, scanning the file in the folder.
When the file stored in the smart television is scanned in S101, a folder is scanned. In this step, each time a folder is scanned, the files in the folder are directly scanned. It should be noted that, when a new folder is continuously scanned in a certain folder, the files in the new folder are continuously scanned until all the files in the folder are scanned, the previous-level folder is skipped to continue scanning, and the step is usually repeated to S101.
S103: and when the scanned file is a non-folder, judging whether the file corresponds to a preset required file type according to the suffix of the file.
In the embodiment of the invention, required file types and suffixes of files corresponding to each file type are required to be preset. In this step, when a file other than the folder is scanned, it is determined whether the scanned file corresponds to a preset desired file type according to the suffix of the scanned file, and whether the scanned file is a desired file is determined. If yes, means that the file is the required file, the following step S104 is executed to save the file basic information of the file; if not, the file is not needed, and the file can be skipped directly to scan other files. And skipping the file if the file does not correspond to the preset required file type.
The file types described above are generally required to include any one or any combination of the following in embodiments of the invention: video files, music files, picture files, apk installation package files. Of course, the specific inclusion scope for the file type is not specifically limited in the present invention facts, as the case may be. In general, the file types in the embodiments of the present invention need to include all of the file types described above.
S104: and saving file basic information of the file.
The file basic information needs to ensure that other software can query the file based on the file basic information, and in particular, the file basic information generally needs to include a file path and a file name in the embodiment of the present invention. Of course, the above-mentioned file basic information is also generally required to include basic information such as a file size.
S105: after the basic information of the files is stored, the number of the files corresponding to any file type is counted.
In general, this step, S104, and S101 to S103 are executed by different threads, that is, S104 is executed to save the basic information of the file that meets the condition while S101 to S103 scan each file, and this step is executed to count the number of files during the saving. In this step, the number of files corresponding to each file type is generally counted separately.
S106: and when the number of the files corresponding to any file type meets the preset condition, sending data updating information corresponding to the file type meeting the preset condition to the target application through the AIDL interface.
AIDL is the Android system interface definition language, and AIDL interface is the interface for carrying out data communication between different processes in the Android system. In the step, communication among different threads in the Android system can be realized through the AIDL interface, so that the data update message can be timely sent to the target application.
In this step, when the number of files meets the preset condition, data update information corresponding to each file type is actively sent to the target application, where the target application includes a file manager, multimedia software, and other software capable of displaying the file scanning progress, and the data update information may generally include information such as a file path, a file name, and a file type of a file stored in the smart television, so that the target application displays the information of the file stored in the smart television according to the data update information.
In general, in this step, when the number of newly added files in any file type reaches a number threshold, for example, when the number of newly added files reaches ten, a data update message is sent to the target application, so that the user can know the information of the stored files in the smart tv through the target application based on the data update message. In this step, the data update message is generally sent to the target application when the number of files newly added in any file type reaches the number threshold value every time.
The file scanning method provided by the embodiment of the invention comprises the steps of scanning files stored in the intelligent television through the JNI interface; when the scanned file is a folder, scanning the file in the folder; when the scanned file is a non-folder, judging whether the file corresponds to a preset required file type according to the suffix of the file; if yes, saving the file basic information of the file; after the basic information of the files is stored, counting the number of the files corresponding to any file type; and when the number of the files corresponding to any file type meets the preset condition, sending data updating information corresponding to the file type meeting the preset condition to the target application through the AIDL interface.
The JNI interface can realize interaction between java codes and C language codes or C++ language codes, and a program constructed based on the C language codes or the C++ language codes can realize scanning of files stored in the intelligent television, and because the C language and the C++ language are closer to the bottom layer language of the computer, the faster file scanning speed can be realized; the AIDL interface AIDL is an Android system interface definition language, and the AIDL interface is an interface for carrying out data communication between different processes in an Android system. Communication among different threads in the Android system can be realized through the AIDL interface, so that the data update message can be timely sent to the target application, and monitoring in the scanning process is realized while the faster scanning speed is realized.

The JNI allows Java codes, codes written by the C++ language and the preset program segments to interact, and the C++ language is closer to the bottom layer, so that compared with a scanning algorithm written by the traditional Java language, the preset program segments have better performance and higher efficiency, and therefore, better scanning speed and memory management can be obtained, and scanning work of a large number of files can be realized in a short time. In the step, a preset program segment constructed based on C++ can be realized by calling the JNI interface, and the file stored in the smart television of the Android system is scanned.
It should be noted that, in the embodiment of the present invention, the files stored in the smart tv include files stored in the smart tv and files stored in the external storage device of the smart tv. And in the scanning process, the files stored in the intelligent television and the files stored in the external storage equipment of the intelligent television need to be scanned.
S202: and when the scanned file is a folder, scanning the file in the folder.
S203: and when the scanned file is a non-folder, judging whether the file corresponds to a preset required file type according to the suffix of the file.
S204: and saving file basic information of the file.
S205: after the basic information of the files is stored, the number of the files corresponding to any file type is counted.
S206: and when the number of the files corresponding to any file type meets the preset condition, sending data updating information corresponding to the file type meeting the preset condition to the target application through the AIDL interface.
The above S202 to S206 are substantially identical to S102 to S106 in the above embodiment of the present invention, and the details are described in detail in the above embodiment of the present invention, which is not repeated here. Specifically, in this step, the data update information includes the number of files corresponding to the file types satisfying the preset condition, and the file basic information corresponding to the file types satisfying the preset condition. And the data updating information can reflect how many files the corresponding file types currently comprise, and include the specific path, name and other basic information of the files.
At this time, after receiving the data update message, the target application may display corresponding information according to its own setting, for example, only the number of the files, that is, the number of files belonging to a certain file type in the files stored in the smart tv, is displayed on the primary interface; and then the file basic information corresponding to the file type can be displayed in a scrolling mode on the secondary interface. Of course, the target application may display the information of the storage file in the smart tv in other manners, which is not specifically limited in the embodiment of the present invention.
According to the file scanning method provided by the embodiment of the invention, the JNI interface specifically realizes interaction between the java code and the C++ language code, and the program constructed based on the C++ language code realizes scanning of the file stored in the intelligent television, and as the C++ language is closer to the bottom language of the computer, the faster file scanning speed can be realized; communication among different threads in the Android system can be realized through the AIDL interface, so that the data update message can be timely sent to the target application, and monitoring in the scanning process is realized while the faster scanning speed is realized.
