Alerts will not normally work in a WebView. You will need to write the code to do that yourself. You can easily do that by implementing your own version of WebChromeClient. In otherwords:

class ChromeClient extends WebChromeClient {
    public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
        Toast.makeText(view.getContext(), message, Toast.LENGTH_SHORT).show();
    }
}

... 
mWebView.setWebChromeClient(new ChromeClient());

Another thing I would recommend is implementing the onConsoleMessage as well. This way you can just use "console.log" in your JavaScript and have it directed to Toast or the Android Log.
