private void forWebviews() {

	final ViewGroup viewGroup = (ViewGroup) ((ViewGroup) this
			.findViewById(android.R.id.content)).getChildAt(0);
			
	int elementSize = getWenViews(viewGroup).size();
	for(int j =0; j< elementSize;j++)
	{			
		WebView getAllWebView = formIsValid(viewGroup).get(j);
		String SplitTypeWebView = String.valueOf(getAllWebView);
		String getWebValues = getAllWebView.getUrl().toString();
		SplitWebViewID(SplitTypeWebView);
	 }	
}

private ArrayList<WebView> getWenViews(ViewGroup viewGroup) {
	
	ArrayList<WebView> webview = new ArrayList<WebView>();
	for (int i = 0; i < viewGroup.getChildCount(); i++) {
		View v = viewGroup.getChildAt(i);
		if (v instanceof WebView) {
			webview.add((WebView) v);

	return webview;
