Check the output of your logcat and add something like this:

    /* WebChromeClient must be set BEFORE calling loadUrl! */
    view.setWebChromeClient(new WebChromeClient() {

        @Override
        public boolean onJsAlert(WebView view, String url, String message, final android.webkit.JsResult result) {
            Log.e("js ", message);
            return false;
        }
    });/ // for debugging convenience.

to also log the javascript errors to logcat.
