File Management Subsystem Changelog
c1.filemanager.1 Change of the fileAccess Module
- Changed the assets that can be managed by the file access framework. The assets managed by the media library cannot be accessed by using the file access framework APIs. Currently, the file access framework supports the following directories:
- External storage directory
- Docs directory
- Download directory
- Desktop directory
- Documents directory
- Share directory of the shared disk
The fileAccess module does not support query of some attributes of thumbnails and media assets.
- Changed the URI format, which eliminates the need for parsing the URI format.
Change Impact
For applications developed based on earlier versions, check whether the URI is obtained by using the media library API through fileAccess. If yes, the URI cannot be obtained.
Key API/Component Changes
The following API is deleted.
| Class | API |
|---|---|
| fileAccessHelper | getThumbnail(uri: string, size: image.Size, callback: AsyncCallback |
The following values are deleted from FileKey.
| Enum | Deleted Key Value |
|---|---|
| FileKey | DURATION = ‘duration’ |
| FileKey | WIDTH = ‘width’ |
| FileKey | HEIGHT = ‘height’ |
Adaptation Guide
The invocation of the fileAccess APIs remains unchanged, but the assets corresponding to the URI returned change.
To obtain attributes such as the file name and path, use fileuri.
To obtain the URI via a file access framework interface, use fs.
