I have an html file that I placed on my Android device via USB (Android File Transfer). Android file transfer doesn't show any paths, so I don't know what directory this file is being placed in. I downloaded a file manager app on the device by ZenUI that suggests the file is in "root/sdcard/theFile.html" but referencing it in an app using "file:///root/sdcard/theFile.html" does not work even if all the appropriate Manifest permissions are in place ("file not found").
I am using a Droid Turbo 2
This is probably device-dependent. On my Nexus 6 is it
(if you placed your file in Downloads).
If you have an SD-Card inside, maybe just trying
emulated/1/... helps, or just download TotalCommander, navigate to the file and look up the properties of the file (
Location:) will help you.
Hope that helps.
