Description
Technical field
The present invention relates to a kind of method of triggered multimedia scan database, especially a kind of triggering Android device is more
The method and device of media database scanning.Belong to mobile device technology field.
Background technology
Current Android device, by taking mobile phone as an example, various mobile phone assistance applications are a lot, such as 91 assistants, pea pods, 360
Mobile phone assistant, Tengxun mobile phone assistant etc.；These mobile phones assistant can operate to mobile phone file system, be essentially all logical
Cross pc adb（Android Debug Bridge）Client, sets up with mobile phone adb servers and is connected, by obtaining mobile phone file
System directory, uses adb orders（Push, pull etc.）, upload down operation is carried out to file；When user is helped by pc ends mobile phone
Hand, by some file push into mobile phone, many files in cellphone directory.But similar photograph album, the application such as music, video is but
Do not find that new file is copied into mobile phone timely, because these applications all rely on Android multimedia database
（The database saves the fileinfo used in T cards and mobile phone）, but multimedia database only can be in start, usb storage moulds
Just meeting active adversary machine storage is scanned during formula switching, and when mobile phone assistant is by adb push orders, copy new file is in one's hands
During machine, multimedia database is not scanned, therefore, and file is not updated in database, cause user can not and
When use file, bring puzzlement to a certain extent to user, and the main method for solving this problem at present is exactly to mobile phone
Storage and T cards carry out scan full hard disk, so that multimedia database is updated, but this method not only takes but also wastes system resource, shadow
The use of mobile phone is rung.
Chinese Patent Application No. is 201110221093.7 application for a patent for invention, discloses " a kind of to be based on android systems
The scan method of the multimedia file of the storage device of system ", its technical characterstic is that scanning process is divided into two stages, first
First by document classification to be scanned in stage, the corresponding information updating of each class is obtained respectively into database, and sets up corresponding
The information that file directory, wherein picture file and video file are added to database only includes file name and path, without
Metdata information is added, the time required for scanning is greatlyd save；Built file directory is supplied to user with breviary diagram form,
Whether user is file to be scanned by thumbnail identification, confirms as carrying out checking that just obtaining metdata believes after file to be scanned
Breath, the problem of solving prior art scanning process duration, there is the wasting of resources, therefore, what the application for a patent for invention was emphasized
It is the realization of scanning process, the technical inspiration of not timely triggered multimedia scan database.
The content of the invention
The invention aims to the defect for solving above-mentioned prior art, there is provided one kind triggering many matchmakers of Android device
