Android Question B4A WebView, How to fit / fix the page inside Webview

Not enough information to help you.

Tip: never use activities. Switch to B4XPages.

Scenario:
We have An Android TV. TV Resolution is 1920 * 1080.
We need to run an HTML Page from URL. Width 1920 and height 1080
If we open the URL in TV android Browser page showing properly and OK.

Problem:
So We make application in B4A with WebView control, with the same Width and height. and make the web view with fullscreen.
After we install the application in TV and Run. Every thing is working fine (Page loading is OK)
only the issue is out of 1920 * 1080 TV shows only 600 * 400 area of the page.

How we can fix this issue.

WebView is a native component. You aren't expected to configure anything. It should show the page with the correct size.

Have you tested it on a phone? Does it show properly?
