Я хочу показывать изображение в формате GIF на экране, даже когда приложение закрыто

Щелчком мыши вы реализуете две вещи:

• Звук играет
  
• Изображение в формате GIF показывает
  .

Я пытаюсь показать GIF на экране, даже когда закрываю приложение, в котором я использую службы, но поскольку звук продолжает воспроизводиться, пока появляется изображение GIF, я не могу найти решение.
