Remarks

Default implementation of android.view.KeyEvent.Callback#onKeyDown(int, KeyEvent) KeyEvent.Callback.onKeyDown(): always returns false (doesn't handle the event).

Override this to intercept key down events before they are processed by the application. If you return true, the application will not process the event itself. If you return false, the normal application processing will occur as if the TV input had not seen the event at all.
