Android WebView: Is it possible to detect URL hash change?

Question

I need to detect URL hash changes in an Android WebView but can\'t find any way to do so. shouldOverrideUrlLoading() fires on the initial page load, but does n

Answer 1

It is possible.

You have to declare a Javascript Interface like this :

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

And link your webview with the Javascript Interface like this :

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

Then, you have to write some javascript code when the page is loaded, to call the function doStuff on hash change.

webview.setWebViewClient(new WebViewClient() {  

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

I hope it helps. I have tested it, and it works.
