我有一个 MediaControllerCompat，它是在建立 MediaSession 连接时创建的一个实例。完成此连接后，我按以下方式创建 MediaControllerCompat:
MediaControllerCompat mediaController = new MediaControllerCompat(this, token);
MediaControllerCompat.setMediaController(this, mediaController);
token 是从MediaSession获取的。
每次按下后退按钮都会检测到泄漏。我没有向 MediaControllerCompat 注册任何回调/监听器。我已经尝试在 Activity 的 onDestroy() 方法上将 MediaController 设置为 null，但没有成功。
MediaControllerCompat.setMediaController(this, null);
