loadUrl() is asynchronous; it will return but the content will not have finished loading (including your fill() javascript method) before you try to invoke fill() on the next line. Try adding a listener for when the page has finished loading and invoke the javascript method from there:

wv.setWebViewClient(new WebViewClient() {
    public void onPageFinished(WebView view, String url) {
        view.loadUrl("javascript:fill()");
    }
});
