Abstract
Embodiments provide the date storage method of a kind of media file and a kind of mobile terminal.Described method includes: the media file in scanning mobile terminal internal card, extracts during in described internal card, the metamessage of media file is stored in the extending database of described mobile terminal.By implementing the present invention, the media file of mobile terminal internal card is synchronization with system database record.
Description
Technical field
The present invention relates to the communications field, particularly relate to date storage method and the mobile terminal of a kind of media file.
Background technology
The mobile phone of existing band android system, when, after start, MediaScanner (media scanner) takes
Media file (the tinkle of bells of some embedded in mobile phone, prompting sound, alarm clock sound etc.) on the business automatic scanning cell phone of meeting
And preserve these media files metamessage (metamessage be reflection media file properties information, than
As, the albumart (album cover) and image (image) of audio (audio frequency)/video's (video)
Thumbnail (thumbnail) is the one of metamessage, and metamessage may also include the special edition of audio, artist,
School etc., image/video's is high wide, longitude and latitude etc.) (built-in to the internal data base of interior of mobile phone
Data base) in；When mobile phone has (or insertion) sd card (Secure Digital) when, MediaScanner
Service can scan the media such as the audio (audio frequency), image (image), video (video) on sd card automatically
File and preserve the metamessage of these media files on sd card to interior of mobile phone external data base (with
Another data base that internal is different, referred to as extending database) in, then extract audio file
Thumbnail (thumbnail) information of albumart (album cover) and image/video file, preserves albumart
With on thumbnail file to sd card；When pulling out sd card, MediaProvider (media database service
Provider) external database file can be unloaded；After again insertable into same sd card, MediaProvider
Can reload external database file.
Currently, all of multimedia application (Music (music) built-in for such as android, Gallery
(picture library), SoundRecorder (recorder), Camera (photographing unit)) read the media file of sd card
During metamessage, it is all inquiry external data base, owing to the metamessage of the media file on sd card all exists
External data base withs a hook at the end, and therefore, thus maintains sd card media file and external data base note
The synchronization of record.
But, existing technical scheme is only capable of realizing the same of sd card media file and external data-base recording
Step, it does not accounts for mobile phone and likely comprises the situation of internal card (such as iNand card).According to existing
Technical scheme, when mobile phone has sd card, Music, Gallery can only read sd card media fileinfo,
And the media file on iNand card can not be read, therefore, when using prior art, it is impossible to realize
The media file of embedded in mobile phone card is synchronization with external data-base recording, is so not inserted into sd when mobile phone
During card, the multimedia application of interior of mobile phone (built-in Music, Gallery, SoundRecorder,
Camera or third party application) can not normally use.
Summary of the invention
The purpose of the embodiment of the present invention is, it is provided that the date storage method of a kind of media file, one are mobile
Terminal.The media file of mobile terminal internal card and/or external card and the same of system database record can be realized
Step, and can realize when mobile terminal is not inserted into external card, the multimedia application within mobile terminal
(built-in Music, Gallery, SoundRecorder, Camera or third party application) can be normal
Use.
In order to realize foregoing invention purpose, embodiments provide the data storage side of a kind of media file
