you should add this to your webchromeclient:
onConsoleMessage (ConsoleMessage consoleMessage)
you can check the documentation to get it working.
it's the only way to debug a webview.

it looks like you have turned off the grant permission prompt with
onPermissionRequest

i haven't done much with webview in a long time, but i seem to remember
granting permission with onPermissionRequest (just like you did) and no
longer seeing the prompt. however, in my case the camera and audio worked
(as i recall), so there may be an error in your case, which will only appear in the
log if you add onConsoleMessage to your chrome client. b4a is designed
to put webchromeclient console messages in the log

You need also to allow runtime permissions for CAMERA, RECORD_AUDIO and optional MODIFY_AUDIO_SETTINGS in manifest and with runtime permissions.
UltimateWebView is deprecated and no longer available. You can try WebkitLibrarySet, but it will not work with devices with SDK25 and below.

camera and audio permissions used to be handled in webview. they are now handled with runtime
permissions and permission requests in the manifest. in addition - and because of this - you need
to grant camera/audio permissions in the webchromeclient. you have done this, or at least, you tried.

in order to debug webview, you need to handle console messages. that means overriding
webchromeclient's normal handling. for the most part, console messages are generated for you;
you simply need to override webchromeclient's handling and redirect them to BA.Log

so, with all of this in mind, do the following

in b4a:

remove this:

B4X:

        we.Initialize(WebView1)
        Dim client As DefaultWebViewClient
        client.Initialize("client")
        we.SetWebViewClient(client)

replace with:

B4X:

    Dim jo As JavaObject
    jo.InitializeContext
    jo.RunMethod("addWCC", Array(webview))

in inline java, do this:
remove your inline java

replace with:

B4X:

#if Java
import android.webkit.*;
    public static void addWCC( WebView wv ) {
        wv.getSettings().setJavaScriptEnabled(true);
        wv.getSettings().setMediaPlaybackRequiresUserGesture(false);
        wv.setWebChromeClient(new WebChromeClient() {
            @Override
               public boolean onConsoleMessage (ConsoleMessage consoleMessage) {
                BA.Log(consoleMessage.message() + " (" + consoleMessage.messageLevel() + ")");
                 return true;
            }


           @Override
              public void onPermissionRequest(PermissionRequest request) {
            wv.evaluateJavascript("console.log('overriding permission request');",null);
               request.grant(request.getResources());    // this alone is enough to grant all the permissions, currently only video/audio
           }
         
         });         // end of add webchromeclient

       wv.evaluateJavascript("console.log('webchrome client added');",null);
     
     }

#End If

when i run a simple webcam app in a webview, my camera opens. as far as webrtc is concerned,
i cannot comment on what you have implemented there. i can only say my camera opens when i
run a simple html document in a webview.
