Android: WebView - not getting Camera and Mic enabled for conference

After getting those permissions, you need to override onPermissionRequest in WebChromeClient like this:

webView.setWebChromeClient(new WebChromeClient() {
  @Override
   public void onPermissionRequest(final PermissionRequest request) {
       request.grant(request.getResources());
}
});
