| 2647 | * ContentViewCore which could contain untrusted content. Particular care |
| 2648 | * should be taken to avoid unintentional access to inherited methods, such |
| 2649 | * as {@link Object#getClass()}. To prevent access to inherited methods, |
| 2650 | * pass an annotation for {@code requiredAnnotation}. This will ensure |
| 2651 | * that only methods with {@code requiredAnnotation} are exposed to the |
| 2652 | * Javascript layer. {@code requiredAnnotation} will be passed to all |
| 2653 | * subsequently injected Java objects if any methods return an object. This |
| 2654 | * means the same restrictions (or lack thereof) will apply. Alternatively, |
| 2655 | * {@link #addJavascriptInterface(Object, String)} can be called, which |
| 2656 | * automatically uses the {@link JavascriptInterface} annotation. |
