Java 在PagerAdapter中应用程序关闭后Exoplayer未停止

我对Exoplayer有问题，无法在应用程序关闭后停止，或者在BottomNavigationView中更改片段，我从API中获取数据，并将其转换到处理数据的Recyclerview/适配器，然后使用PagerAdapter显示带有图像和视频的数据

我还尝试在片段中设置onDestroy，但不起作用

FeedAdapter.java

public class FeedAdapter extends RecyclerView.Adapter<FeedAdapter.ViewHolder> {
    private final List<FeedData> feedList;

        this.feedList = feedList;
