-/**
- * Helper to display Google web content, and fallback on a static message if the
- * web content is unreachable. For example, this can be used to display
- * "Legal terms".
- * <p>
- * The typical usage pattern is to have two Gservices settings defined:
- * <ul>
- * <li>A secure URL that will be displayed on the device. This should be HTTPS
- * so hotspots won't intercept it giving us a false positive that the page
- * loaded successfully.
- * <li>A pretty human-readable URL that will be displayed to the user in case we
- * cannot reach the above URL.
- * </ul>
- * <p>
- * The typical call sequence is {@link #setUrlsFromGservices(String, String)},
- * {@link #setUnsuccessfulMessage(String)}, and {@link #loadUrl()}. At some
- * point, you'll want to display the layout via {@link #getLayout()}.
