How to hide "Start Video Playback" button when autoplaying video in WebView

I have a simple WebView rendering an HTML5 page that has video playing in the backdrop.. I set the video to play automatically by

browser.getSettings().setMediaPlaybackRequiresUserGesture(false);


It works except the "Start Video Playback" button is still there. When I click the button it does nothing as the video is already playing.. is there any way to hide this button? I searched and found nothing.

enter image description here

EDIT: this worked!

browser.setWebChromeClient(new WebChromeClient() {
@Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);

browser.loadUrl("javascript:document.getElementById('VideoClipPlayButton').click();"
}
});

Answer

I found a solution to your problem. You just have to add a new Javascript that will turn off the button when the page is loaded . Codes below has been tested and works. I checked in C # but Java is very similar so it must work.

JAVA

wv.loadUrl("http://app.singular.live/webchannels/298/onair");
wv.getSettings().setMediaPlaybackRequiresUserGesture(false);
wv.getSettings().setPluginState(PluginState.ON);
wv.getSettings().setJavaScriptEnabled(true);
wv.getSettings().setAllowFileAccess(true);

wv.setWebViewClient(new WebViewClient()
{
  public void onPageFinished(WebView view, String url)
     {
    //here create new JS find element in page (button) and set visibility to hidden
    wv.loadUrl("javascript:document.getElementById('VideoClipPlayButton').style.visibility = 'hidden';");
       }
});

C# (XAMARIN)

    Button button = FindViewById<Button>(Resource.Id.MyButton);
    WebView wv = FindViewById<WebView>(Resource.Id.webView1);
    wv.Settings.JavaScriptEnabled = true;
    wv.LoadUrl("http://app.singular.live/webchannels/298/onair");
    wv.Settings.MediaPlaybackRequiresUserGesture = false;
    wv.Settings.PluginsEnabled = true;
    wv.Settings.SetPluginState(WebSettings.PluginState.On);
    wv.Settings.JavaScriptEnabled = true;
    wv.Settings.AllowFileAccess = true;


     button.Click  += (s, e) =>
     {
         wv.LoadUrl("javascript:document.getElementById('VideoClipPlayButton').style.visibility = 'hidden';");
     };
