Answer 2

You can invoke methods and functions in your webview by using javascript url's, e.g.

webview.loadUrl("javascript:somemethod()");

You will, of course, need to enable javascript on your webview:

webview.getSettings().setJavaScriptEnabled(true);

This is from java to javascript. If you want to invoke java code / android API's from javascript, use addJavascriptInterface()

webview.addJavascriptInterface(new MyJSJavaBridge(), "api");

All of this is shown in the example url you posted as well.
