Android Question Black incoming video ussing webview in WebRTC

[scsjc]

some time ago I used this code to make a videocall using the WebRTC, and it worked perfectly.
attached code:

Sub Activity_Create(FirstTime As Boolean)
    WebView1.Initialize("WebView1")
    WebView1.Visible=True
    WebView1.BringToFront
    Activity.AddView(WebView1,0,0,100%x,100%y)
    
    Dim nameroom As String = "room1234"
    Activity.Title="https://appr.tc/r/" & nameroom 'addess to conect room from weburl
    
    rp.CheckAndRequest(rp.PERMISSION_CAMERA)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result Then
        rp.CheckAndRequest(rp.PERMISSION_RECORD_AUDIO)
        Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
        If Result Then
            Dim client As JavaObject
            client.InitializeNewInstance(Application.PackageName & ".main$MyChromeClient", Null)
            Dim jo As JavaObject = WebView1
            jo.RunMethod("setWebChromeClient", Array(client))
            
            WebView1.LoadUrl("https://appr.tc/r/" & nameroom)
        End If
    End If
End Sub

#if Java
import android.webkit.*;
public static class MyChromeClient extends WebChromeClient {
@Override
     public void onPermissionRequest(PermissionRequest request) {
        request.grant(request.getResources());
    }
}
#End If

I do not know if due to some update by WebRTC or the webview, but when users connect in the same VideoChat the Android terminal through webview only displays a black screen.

Does anyone know why it may be due?
thank you

yes, this example worked correctly, but recently (I think some update of the ccs of webrtc, or something similar) the webview does not show the incoming video on the android, and there is a black layer.
