Referring to fig. 1, fig. 1 is a flowchart illustrating a file scanning method according to an embodiment of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a file scanning method includes:
s101: and scanning files stored by the intelligent television through the JNI interface.
JNI is an abbreviation of Java Native Interface, and codes can be guaranteed to be conveniently transplanted on different platforms by writing programs through a Java Native Interface. 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 for implementing java code and code constructed based on C + + language, and interacting with code constructed based on C language. Correspondingly, in the embodiment of the invention, the smart television is a smart television with an Android system.
S102: when the scanned file is a folder, the file in the folder is scanned.
When the files stored in the smart television are scanned in S101, the folders are 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 file in the new folder is continuously scanned until all the files in the folder are scanned, the previous folder is jumped to continue scanning, and it is usually necessary to loop back to S101 after this step.
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 present invention, the required file types and suffixes of files corresponding to each file type need to be preset. In this step, when the non-folder file is scanned, whether the scanned file corresponds to the preset required file type or not and whether the scanned file is the required file or not are judged according to the suffix of the scanned file in this step. If yes, the file is a required file, and the following step S104 is executed to store the file basic information of the file; if not, the file is not the required file, and the file can be skipped over directly to continue scanning other files. And skipping the file if the file does not correspond to the preset required file type.
The above file types generally need to include any one or any combination of the following in embodiments of the present invention: video files, music files, picture files, and apk installation package files. Of course, the specific inclusion range of the file type is not particularly limited in the present invention, as the case may be. Generally, the file types need to include all the above file types in the embodiment of the present invention.
S104: and saving the 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, in the embodiment of the present invention, the file basic information generally needs to include a file path and a file name. Of course, the basic information of the file usually needs to include basic information such as the size of the file.
S105: after the basic information of the files is saved, the file number of the files corresponding to any file type is counted.
In general, this step, the above-mentioned S104 and the above-mentioned S101 to S103 are all executed by different threads, that is, while the above-mentioned S101 to S103 scan each file, S104 is executed to save the file basic information meeting the condition, and this step is executed to count the number of files when saving. In this step, the number of files corresponding to each file type is usually counted separately.
S106: and when the number of the files corresponding to any file type meets a preset condition, sending data updating information corresponding to the file type meeting the preset condition to the target application through the AIDL interface.
The AIDL is an Android system interface definition language, and the AIDL is an interface for data communication among different processes in the Android system. In this step, communication among different threads in the Android system can be realized through the AIDL interface, so that the data updating message can be sent to the target application in time.
In this step, when the number of files meets a preset condition, data update information corresponding to each file type is actively sent to a target application, where the target application includes a file manager, multimedia software and other software capable of displaying a 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 information of the file stored in the smart television according to the data update information.
In this step, in general, when the number of newly added files in any file type reaches a number threshold, for example, the number of newly added files reaches ten, a data update message is sent to the target application, so that the user can know information of the files stored in the smart television based on the data update message through the target application. It should be noted that, in this step, the data update message is generally sent to the target application when the number of newly added files of any file type reaches a number threshold value every time.
The file scanning method provided by the embodiment of the invention comprises the steps of scanning files stored in an intelligent television through a JNI (just noticeable information) 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 a suffix of the file; if so, saving the file basic information of the file; after the basic information of the files is saved, counting the number of the files corresponding to any file type; and when the number of the files corresponding to any file type meets a 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 the 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 realizes the scanning of files stored in the smart television; the AIDL interface AIDL is an Android system interface definition language, and the AIDL interface is an interface for data communication among different processes in the Android system.
