WebViewer - Beginner needs help

Beginner needs help Hello;
First of all I would like to apologize for my English and hope that I can explain my problem?
I have created an APP and would like to display a CSV list in WEBVIEW.
In order to get to grips with WEBVIEW and learn about it, I found a simple APP here in the forum and tried it out. It should actually work, but it doesn't for me.
I have found a lot of information about this here in the forum and on the internet. Unfortunately the options I found don't work! With the attached block I always get the message Error 401 or ERR_Address_UNRECHABLE
I have tried the URLs shown in the picture in the home URL!

Can anyone tell me or explain what is or could be the reason for this?

I'm probably not seeing the forest for the trees again, if it is a simple error, I apologize in advance!

Thanks in advance for your help!

Mike

This won't work:

This should work if your html file is in the media folder / assets

This should work if your html file is in the root of a local network server, and your app project / companion / compiled app device is on the same wifi network:

Servers are down at present so cannot offer much more...

I think that's where the problem lies! I haven't saved the file yet / put it in the directory! As soon as I get home I'll do that and try it!

Thanks for the help and probably the solution. It's so logical and yet you can't see the solution! (hopefully)

and what do I have to do so that my table1.html file can handle / process the received data?

Use Javascripts.

First understand how the webviewstring works:

then follow this example to create your table:

You might also consider using the Tableviewer extension, if you can use extensions ?
