Android Question Webview display from Assets

[casher2]

Copied simple one line [test.html] to Files with Add File.

Load Layout with one view [WebView1]

Command: WebView1.LoadUrl("file:///android_asset/test.html") gives the following error:

file:///android_asset/test.html could not be found.

(there are no problems with the html file, itself)

Hate asking these beginner questions, but that's what I am!

Thanks

The Android file system is case sensitive. best to control if your file is realy test.html and not Test.html...

File is all lower case. I've tried various HTMLfiles, all work in browser and if I use Webview1.LoadHTML with the HtML text, it loads fine. Just won't find the file in Assets.
Is it as simple as copying the file to [Files]?
Thanks for reply.

I stumbled across a solution. Don't know why previous didn't work but this does:

File.Copy(File.DirAssets, "test.html", File.DirDefaultExternal, "test.html")
WebView1.LoadUrl("file://" & File.Combine(File.DirDefaultExternal, "test.html"))

Obviously, the test.html does exist or copy file wouldn't work so still puzzled by 'not found error' reported above.

Still interested in answer if anyone could explain.

Just a noob myself, so i am also guessing

Try:

WebView1.LoadUrl(File.DirAssets, "test.html")

Try:

WebView1.LoadUrl(File.DirAssets, "test.html")

Gave it a shot. Had to change slightly due to syntax error (needs all in quotes): WebView1.LoadUrl("File.DirAssets,test.html")

Got the same error but thanks for the effort/idea. Would guess there's a simple answer but these noob questions seem to get little response from the experts...too bad.
Surely been answered before somewhere but specifics are very hard to find, for me at least.

Nood questions DO get response here. Trust me!

I think i solved it. See the code here and take care of the #DebuggerForceStandardAssets: true here. See also the attached projetct. It is working fine for me.

Brilliant! Thank you! Suspect my problem was with: #DebuggerForceStandardAssets: true
