Trying to load and view some HTML that contains an image (question.gif) but when I compile I get the message file question.gif not used and the loadhtml command does not work. is there something I have missed. I have added the file using the file manager.

In order to help you it is better to provide the code or at least the relevant portion of the code you are working with.


cheers,
Walter

The code is:

Webview1.Initialize("")
Webview1.LoadHtml("<html><body><img src='file:///android_asset/question.jpg'/></body></html>")

You have to add the webview to the activity before you load the HTML
B4X:
Webview1.Initialize("")
Activity.AddView(Webview1, 0dip, 0dip, 100%x, 100%y)
Webview1.LoadHtml("<html><body><img src='file:///android_asset/question.jpg'/></body></html>")

A more recent update - it looks like that in later versions of Android you can no longer access items from the DirAssets folder in a WebView LoadHTML statement. I guess that this might be a security issue.

This indirect method works though if you copy the file to the internal directory first though.

B4X:
File.Copy(File.DirAssets,"ic_menu_home.png",File.DirInternal,"ic_menu_home.png")
Dim HTML As String
HTML=$"
<HTML>
<BODY>
<img src='file://${File.DirInternal}/ic_menu_home.png' >
Use the Home Icon to return to the Account Summary.
</BODY>
</HTML>
"$
    WebView1.Enabled=True
    WebView1.Visible=True
    WebView1.Invalidate
    WebView1.LoadHtml(HTML)
