Preferably, the Media Survey unit is also used to the file in the external equipment by scanning and is filtered, and is obtained
Multimedia file after filter obtains the address of multimedia file.
The beneficial effects of the present invention are: one kind provided by the invention is based on the quick scanning system of Android multimedia,
In android system, external file is scanned by Media Survey unit, obtains the ground of the media file in external equipment
Location；It, will be in the address deposit first database of media file by media storage unit；Monitoring external equipment by application layer is
No insertion issues broadcast after external equipment insertion.One kind provided by the invention is quickly scanned based on Android multimedia is
System can be scanned the equipment of outside insertion by the way that the application layer in android system is autonomous, can be effective, fast
Speed is scanned the file in external equipment.
Detailed description of the invention
Fig. 1 is the structural block diagram of the embodiment of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
As shown in Figure 1, the present invention, which provides one kind, is based on the quick scanning system of Android multimedia, including android system,
Include: in android system
Media Survey unit obtains the ground of the media file in external equipment for the file in external equipment to be scanned
Location.It should be understood that media storage unit refers to a kind of virtual Media Survey unit in android system
(MediaScanner), it after the file in external equipment is scanned by Media Survey unit (MediaScanner), sweeps at this time
The file retouched is all files of external equipment, obtains the ground of filtered individual media file by traversing All Files
Location.All files are scanned into resolution file relative to existing, scanning speed can be improved, the data that user needs are shown
Show.
The address of media file is stored in the first data for interacting with Media Survey unit by media storage unit
In library.It should be understood that the interaction carried out between media storage unit and Media Survey unit is frequent, media storage list
Interaction between member and Media Survey unit can be carried out by broadcast, and media storage unit refers to MediaProvider data
Library, MediaProvider database will call MediaScanner database to carry out next step after receiving the broadcast of scanning
Scanning.First database refers to the external database in android system.
Application layer receives the broadcast of the sending of external equipment for monitoring external equipment.Application layer refers to Android
Application layer (Application) in system, application layer (Application) be used for be responsible for external equipment Mount and
UMount is monitored.When being monitored using application layer, is conducive to control Media Survey unit and quickly media file is scanned,
Be conducive to media file to be quickly scanned.
The address of media file in obtained external equipment is sent to bottom by JNI local interface by Media Survey unit
In layer media decoding library, bottom media decoding library is used to for the address information of file being decoded, and by decoded file
Location is transmitted in media storage unit, and decoded file address is stored in database by media storage unit.File is scanning
Broadcast is completed and can issue after the completion of decoding, notice application layer carries out relevant operation.It should be understood that file
Two steps are scanned and be decoded as, time of the file the time it takes much smaller than one file of decoding is scanned.
The address of media file at least one, application layer stores the address of media file by array.It should manage
Solution, the address for the media file that application layer obtains are sequentially stored into array, which records each media text for storing
The address of part forms address list, called convenient for the address of media file.
The address of media file is also transmitted directly to carry out single file parsing scanning in Media Survey unit by application layer.
Application layer can take the All Files stored in external equipment, customized mistake by program filepath.listFiles ()
File format is filtered, desired file path is obtained by filtration to traverse, can be inserted into the single file of filtering when filtering
Database.Compared with the existing technology, external equipment is carried out whole scannings, and meeting resolution file data by system, and can be corresponding
File information storage to corresponding database in this process can save a large amount of time.It should be understood that application layer
Filtering can only be previously obtained the path of corresponding document, will not relate to the operation of database during obtaining path, and
It is that temporary file is stored in array.
After the completion of Media Survey unit scan, application layer also issues broadcast notice media storage unit control Media Survey list
All files in android system are scanned by member.After the completion of Media Survey unit scan, for convenient for android system
In the relevant file of other application software transfer, by application layer broadcast notice Media Survey unit scan file, thus
In the case where not influencing other software application, scanning that is effective, being rapidly performed by media file.
It further include being detected to external equipment based on the quick scanning system of Android multimedia, external equipment detection packet
It includes and external equipment is detected using external equipment driving and media framework layer.External equipment includes SD card and flash card, matchmaker
Body ccf layer refers to framework layers in android system.
Media Survey unit is also used to the file in the external equipment by scanning and is filtered, and obtains filtered multimedia
File obtains the address of multimedia file.It should be understood that filtering is to refer to determining scanning in the file of external equipment
File whether be media file, the files such as media file such as music, video, picture, if not the file of corresponding format, then
The address information of this document is not recorded.
A kind of Android multimedia scanning system that is based on provided by the invention is swept in android system by media
It retouches unit to be scanned external file, obtains the address of the media file in external equipment；By media storage unit, by matchmaker
In the address deposit first database of body file；Monitor whether external equipment is inserted by application layer, after external equipment insertion just
Issue broadcast.By application layer come the scanning of control system, application layer oneself realizes an external equipment scan service, application layer
Then the filtering for realizing associated media file is controlled again in single file deposit system database, such operation can save greatly
The time of amount meets the needs of vehicle-mounted hot plug quickly scans.The present invention can be rapidly obtained corresponding media resource, and
Without waiting for the very long scanning process of system, optimizes frequent fast insert-pull external equipment to a certain extent and read that file is slow to ask
Topic.The part media framework layer (framework) logic gives application layer, and application layer can control certain scanning logic, customization
It is higher to develop freedom degree, is more able to satisfy the demand of exploitation.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
