CustomWebView : An extended form of Web Viewer

I got this error: Property getter was expecting a com.google.appinventor.components.runtime.WebViewer component but got a String instead with this code, and the webviewer was only taking up half the bottom and not the whole thing. Why


Another example of mixing customwebview and webview extra.
Use only one.

Is your issue relevant to CustomWebView?

I was using customwebview and last time I had a question like this my topic got forwarded to here. So I was just saving the trouble

Sorry to interfere... I'm adding support for JS alerts but it freezes the webpage, I tried
dismiss JS alert but it does nothing, Here is the code.

I used a screenshot from another post and this is my code, yet the file directory says it is not valid or something

I thought I tried that all ready but it worked thank you, it might have been a problem with the name and when I changed it, it worked.

I am using this code and when I use a link it gives me the error and when I said to ignore SSL errors, nothing else happened, and then I said to follow links, but that did not work. I am using CustomWebviewer by VKnow360

This file has 3 extensions. Browserprompthelper, downloadhelper, and customwebview. I only want the last 2. But when I import the extension and try to remove browerprompthelper in mit app inventor all 3 get removed. Is their a way to change the file or do this anyother way?

Use this method to load your html files from assets

Looks like you need to do more work to get index(11).html working...

3d odel is not loading it means html unable to get asset link, what should be the source link for working currently i am using src="glass.glb"

Try http://localhost/glass.glb

still not working

Check your glass.glb, i tested with your 2cylinderengine.glb as an asset and that worked OK.
