How do I get the web page contents from a WebView?


On Android, I have a WebView that is displaying a page.

How do I get the page source without requesting the page again?

It seems WebView should have some kind of getPageSource() method that returns a string, but alas it does not.

If I enable JavaScript, what is the appropriate JavaScript to put in this call to get the contents?

webview.loadUrl("javascript:(function() { " +  
    "document.getElementsByTagName('body')[0].style.color = 'red'; " +

I know this is a late answer, but I found this question because I had the same problem. I think I found the answer in this post on The code below is basically a cut-and-paste from the site. It seems to do the trick.

final Context myApp = this;

/* An instance of this class will be registered as a JavaScript interface */
class MyJavaScriptInterface
    public void processHTML(String html)
        // process the html as needed by the app

final WebView browser = (WebView)findViewById(;
/* JavaScript must be enabled if you want it to work, obviously */

/* Register a new JavaScript interface called HTMLOUT */
browser.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");

/* WebViewClient must be set BEFORE calling loadUrl! */
browser.setWebViewClient(new WebViewClient() {
    public void onPageFinished(WebView view, String url)
        /* This call inject JavaScript into the page which just finished loading. */

/* load a web page */

Per issue 12987, Blundell's answer crashes (at least on my 2.3 VM). Instead, I intercept a call to console.log with a special prefix:

// intercept calls to console.log
web.setWebChromeClient(new WebChromeClient() {
    public boolean onConsoleMessage(ConsoleMessage cmsg)
        // check secret prefix
        if (cmsg.message().startsWith("MAGIC"))
            String msg = cmsg.message().substring(5); // strip off prefix

            /* process HTML */

            return true;

        return false;

// inject the JavaScript on page load
web.setWebViewClient(new WebViewClient() {
    public void onPageFinished(WebView view, String address)
        // have the page spill its guts, with a secret prefix
