Android WebView: is it possible to change the hash of a url?

I need to detect URL hash changes in Android WebView, but cannot find a way to do this. shouldOverrideUrlLoading()It fires when the page loads, but it does not start for subsequent hash changes after the page loads.

Is this possible with Android WebView?

Maybe.

You must declare a Javascript interface as follows:

private class MyJSI {
         public void doStuff()
         {
         }
}

And link your webview to the Javascript interface as follows:

webView.addJavascriptInterface(new MyJSI(), "myjsi");

Then you need to write javascript code when loading the page to call the doStuff function when the hash changes.

webview.setWebViewClient(new WebViewClient() {  

         public void onPageFinished(WebView view, String url)  
         {
                 view.loadUrl("javascript:window.onhashchange = function() { myjsi.doStuff(); };");
         }
});

Hope this helps. I tested it and it works.
