Description
Technical field
The present invention relates to mobile communication technology field, more particularly to a kind of management method of virtual external storage,
Device and terminal.
Background technology
Android M systems introduce SD card (Secure Digital Memory Card, safe digital card) formatting
For the function of built-in storage.After user inserts SD card, it can select SD card being formatted as built in memory device.In being formatted as
The part that the SD card of portion's storage will store as internal system, for extending internal system storage size.
Before SD card is inserted, in order to provide using the function of preserving user data, android system is by sharing data
The mode of subregion, by system /data/media catalogues invent a type be emulated external storage, then
External deposit is mounted to by FUSE (Filesystem in Userspace, user's space file system) daemon service processes
Equipment mount point is stored up to access for upper layer application.Because system is using the scheme of shared data subregions, the emulated come is fictionalized
The amount of capacity of the external storage of type is the size of data subregions.
After inserting SD card, after SD card carry, user can select SD card being formatted as built in memory device.Work as SD card
After being formatted as storage inside, system can on SD card root a newly-built media catalogue, then by the media mesh
Record invents the external storage of another emulated type, and follow-up system can be by FUSE daemon carries simultaneously
Access the external storage.
Because current system only supports the external storage of one emulated type of carry, acquiescence is in start process
By system/data/media catalogues fictionalize come emulated type external storages.If it is desired to by user data
Be saved in SD card be formatted as after built in memory device by the media catalogues of SD card root fictionalize come emulated classes
Type external storage, user are needed by the transfer data menu of SD card or during SD card formats built-in store
Moving operation is selected, is first deleted the content of target emulated type external storages in SD card, then general/data/
The copy content of media catalogue corresponding source emulated type external storages is set to the external storage of target emulated types
It is standby upper, then the content of source emulated type external storages is deleted again, finally again by FUSE daemon service into
Target emulated type external storages are mounted to external storage mount point by journey.
In addition, after emulated type external storages corresponding to carry SD card are selected, if user unloads SD card,
The external storage without emulated types is now in carry state in system.If system is by outside emulated types
Main storage device of the storage device as system is put, then system hosts storage equipment can be caused to be not present, upper layer application can not preserve
The problem of user data.
