Android Question Webview file not found error

Following this example here:

I've put the animated GIF in the Files folder of my project, along with an HTML file, called StartupOverlay.html, which has the following code:

<html><body><img src="lambda_flat_rotating_black_152x200.gif" /></body></html>

The code in B4A looks like:
Dim wv1 As WebView
StartupOverlayPanel.AddView(wv1, 0, 0, 100%x, 100%y)
But getting the error: Webpage not available, The webpage at
file:///android_asset/StartupOverlay.html could not be loaded because: net::ERR_FILE_NOT_FOUND[/code]

I think I followed the example correctly, but I can't see the error that I must be making.

There is a difference in using assets in debug and release mode.
In debug you can use something like 'force assets'.
In release mode it should work without that.
Which mode do you use?

(not sure if this is the solution for your problem....:oops:)

Thanks for the answer, but, actually, I can close this because I'm going to use an HTML file on my webserver instead (and I've got that working okay).

As a follow-up, though - I did try it in Release mode and it worked correctly. And...

#DebuggerForceStandardAssets: True it to work in Debug mode.
