WebViewExtra
An extension for AI2 that extends the features of the native webviewer.
The extension, by default, will provide the following features:
- allow for uploading of files from within a webviewer. (Developers will need to provide suitable html solutions...)
- allow for downloading of files from within a webviewer, even from Google Drive shared folders! Files are saved to the Download directory in Shared storage.
- sets READ and WRITE permissions in the app / aia project, enabling the setting of Legacy as a default filescope for storage of files in Shared directories. This is useful for providing access to files in the ASD (which would need to be copied to a shared directory location for uploading).
- allow for file access from the webviewer.
- allow for some control over zoom in the webviewer.
- allow for the use of localStorage and sessionStorage in html/javascript in a webviewer.
- modifies the userAgent of the webviewer, removing the
; wv
, which then enables (for example) Google 0Auth activities, such as authorising web apps with a user's google account.
