Android WebView показывает пустую страницу при воспроизведении Html с iframe

Question

Я пытаюсь html файл показать внутри WebView в android, но при попытке увидеть черный экран на моем android телефоне, Html имеет iframe

Html код

<iframe style="width:100%; height:100%;" id="webPage" frameborder="0" src="http://www.youtube.com/embed/XGSy3_Czz8k">
</iframe>


<script>
    var Url, Interval;

    function init() {
        document.getElementById('webPage').setAttribute('src', Url);
    }
    function setParams(params) {
        //console.log(params);
        params.forEach(element => {
            switch (element.key) {
                case "Url":
                Url = element.value;
                    break;
                case "Interval":
                Interval = element.value;
                    break;
            }
        });
        document.getElementById('webPage').setAttribute('src', Url);

        setInterval(function () {
            document.getElementById('webPage').setAttribute('src', Url);
        }, (Interval * 60 * 1000));
    }

    function listener(event) {
        setParams(event.data);
    }
    if (window.addEventListener) {
        window.addEventListener('message', listener, false);
    } else if (window.attachEvent) { // ie8
        window.attachEvent('onmessage', listener);
    }

    function deleteContent()

{try {var el = document.getElementById ('webPage'); el.setAttribute ( 'ср c, "о: пустой"); el.parentNode.removeChild (эл); } catch (err) {console.log ("ОШИБКА удаления веб-страницы:" + err); }}

попробуйте это ->

создайте пользовательский веб-просмотр:

public class TouchyWebView extends WebView {

public TouchyWebView(Context context) {
    super(context);
}

public TouchyWebView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public TouchyWebView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
public boolean onTouchEvent(MotionEvent event){
    requestDisallowInterceptTouchEvent(true);
    return super.onTouchEvent(event);
}}

включите его в свой xml (вместо веб-просмотра):

 <com........TouchyWebView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/webview"
    />

добавить это в деятельности:

ws.loadDataWithBaseURL(null,"file:///android_asset/index.html", "text/html", "UTF-8", null);

    WebSettings settings = ws.getSettings();
    WebSettings webSetting = ws.getSettings();

    webSetting.setBuiltInZoomControls(true);
    settings.setDomStorageEnabled(true);
    ws.getSettings().setJavaScriptEnabled(true);
    ws.setVerticalScrollBarEnabled(true);
    ws.setHorizontalScrollBarEnabled(true);
    ws.setAllowFileAccess(true);
    ws.setAllowFileAccessFromFileURLs(true);
    ws.setAllowUniversalAccessFromFileURLs(true);
     ws.setJavaScriptEnabled(true);
     ws.setJavaScriptCanOpenWindowsAutomatically(true);
     ws.setAllowContentAccess(true);
     ws.setDomStorageEnabled(true);
