You need to place the file outside of the downloads folder.
Its basically the root storage path of the device. So within a file explorer app, you will be able to see folders such as kioskbrowser, pictures etc...
For your information we have updated our API to allow updating of file groups and file group files.
You can use %LOCALCONTENT% as the URL which points to the folder kioskbrowser/localcontent. Alternatively you can use %LOCALSTORAGE% more information can be found here http://kioskbrowser.userecho.com/forums/2-knowledge-base/topics/72-url-parameters/
As mentioned in the article, we currently only expose the kioskurl property.
No I'm afraid there is no such feature in Kiosk Browser.
No I'm afraid this is not possible. Google changed the way apps are granted permissions in Android 6.0 or higher, we can't grant permissions ourselves.
