mWebView.setWebChromeClient(new WebChromeClient());
mWebView.getSettings().setJavaScriptEnabled(true);
// settings.setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);


mWebView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageFinished(WebView view, String url) {
       String javascript = "javascript:(function()     {document.getElementById('msg').innerHTML='Hello'})()";
 view.loadUrl(javascript);
    }
});
refreshWebView();
return view;
}
 private void refreshWebView() {
 mWebView.loadUrl(URL);
}
@Override
public void onClick(View v) {
refreshWebView();
}
