No hay motivo para implementar esta interfaz directamente. En su lugar, los eventos personalizados deben implementar CustomEventBanner y CustomEventInterstitial.
Se llama al final del ciclo de vida del evento personalizado. Se espera que el adaptador libere los recursos y se cierre. Después de llamar a este método, es posible que las llamadas posteriores a cualquier otro método de este adaptador arrojen un IllegalStateException.
No se garantiza que se llame a este método. Existen varios motivos por los que se puede omitir este método, como el cierre forzado de la aplicación.
Se llama cuando la aplicación llama a pause. Se espera que el evento personalizado detenga cualquier procesamiento asociado con el anuncio que se muestra.
