HTML, CSS and JavaScript for Android WebView Depending on your requirements, you can fetch the contents of the WebView from the web using webView. loadUrl("<url>") method, or you can bind the code directly (e.g. after loading it from assets) using webView. loadDataWithBaseURL("", html, "text/html", "UTF-8", null) .
Since Android 4.4 (KitKat), the WebView component is based on the Chromium open source project. WebViews now include an updated version of the V8 JavaScript engine and support for modern web standards previously missing in old WebViews.
I am not sure how far this is going to be helpful. But I have used the below snippet to fetch a small html page's data. I hope it helps you.
Create a class like the one below,
class MyJavaScriptInterface
{
@SuppressWarnings("unused")
public void processHTML(final String html)
{
Log.i("processed html",html);
Thread OauthFetcher=new Thread(new Runnable() {
@Override
public void run() {
String oAuthDetails=null;
oAuthDetails=Html.fromHtml(html).toString();
Log.i("oAuthDetails",oAuthDetails);
}
});OauthFetcher.start();
}
}
Now in your onCreate(),
webview.getSettings().setJavaScriptEnabled(true);
webview.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
webview.setWebViewClient(new WebViewClient(){
@Override
public void onPageFinished(WebView view, final String url) {
String oAuthUrl=getString("www.google.com");
if(url.contains(oAuthUrl))
{
Log.i("Contains","Auth URL");
twitter_webview.loadUrl("javascript:window.HTMLOUT.processHTML('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
}
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressDialog.show();
}
});
And now what happens is that, when your page finishes loading, the JavaScript class will be called, which would retrieve the page source and store it in a String as your requirement.
