I get this intermittent error when I play a video in webview. It appears intermittently at various points of user interaction with the video. I have tried webview1.release when the user presses the Back Nav control button.

If I set WebView1.UserInteractionEnabled = False, it helps, but this is not ideal for my app.

B4X:
Sub PlayVideo(videoId As String)
NavControl.ShowPage(Page2)
WebView1.UserInteractionEnabled = True
Dim no As NativeObject = WebView1
no.RunMethod("setMediaPlaybackRequiresUserAction:", Array(true))
WebView1.LoadHtml($"<!DOCTYPE html><html>
<head>
<style>body{margin:0px 0px 0px 0px;}</style></head>
<body> <div id="player"></div>
<script> var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player; function onYouTubePlayerAPIReady()
{ player = new YT.Player('player', { width:'${WebView1.Width}', height:'${WebView1.Height}', videoId:'${videoId}', events: { 'onReady': onPlayerReady, } }); }
function onPlayerReady(event) { event.target.playVideo(); }
</script> </body> </html>"$)
End Sub
