Android, local PDF and the Browser Widget

[Dan Friedman]

Can anyone tell me why this fails on Android, when it works on iOS and desktop:

put specialFolderPath("documents") & "myTemp.pdf" into fPath
put someRandomPDFData into url ("binfile:" & fPath)
set the url of widget "Browser1" to fPath  //I get a white screen

I have also tried:
set the url of widget "Browser1" to ("file:/" & fPath)
set the url of widget "Browser1" to ("file://" & fPath)

FWIW, this returns true:
answer (there is a file fPath)

I have verified that someRandomPDFData is valid PDF data and the detailed files returns the correct file name and size

Using LC 9.0.1
