[疑惑]：下载文件配合EasyWindow使用，下载完关闭浮窗报错

[hcx1002]

问题描述【必填】

下载文件配合EasyWindow使用，下载完关闭浮窗报错，下载中时，悬浮窗的界面数值可以更新，下载完成要关闭浮窗时，却报错。既然下载中界面可以更新，为什么还会报这个错误，尝试了EventBus、AppUpdateWindow里面的handle也是一样的错误

下载文件代码：
`

 EasyHttp.download(lifecycleOwner)
                .method(HttpMethod.GET)
                .file(new File(Utils.getContext().getExternalFilesDir(null), "zds_app_update.apk"))
                .url(url)
                .listener(new OnDownloadListener() {
                    @Override
                    public void onDownloadProgressChange(File file, int progress) {
                        Button button = AppUpdateWindow.getInstance().getContentView().findViewById(R.id.update_button);
                        button.setOnClickListener(null);
                        button.setText("正在更新："+progress);
                    }

                    @Override
                    public void onDownloadSuccess(File file) {
                        ToastUtils.success("更新下载完成，请点击安装");
                        AppsUtils.installApp(file);
                    }

                    @Override
                    public void onDownloadFail(File file, Exception e) {
                        ToastUtils.error("更新失败，请联系客服！");
                    }

                    @Override
                    public void onDownloadEnd(File file) {
                        AppUpdateWindow.getInstance().cancel();
                    }
                }).start();`

AppUpdateWindow浮窗代码：
`public class AppUpdateWindow extends EasyWindow implements LifecycleOwner {
private static AppUpdateWindow instance;
private final LifecycleRegistry mLifecycle = new LifecycleRegistry(this);

public AppUpdateWindow(Application application) {
    super(application);
    mLifecycle.addObserver(new DefaultLifecycleObserver() {
        @Override
        public void onDestroy(@NonNull LifecycleOwner owner) {
            cancel();
        }
    });
}
public static AppUpdateWindow getInstance() {
    if (instance == null) {
        instance = new AppUpdateWindow(Utils.getContext());
        instance.setGravity(Gravity.CENTER).setOutsideTouchable(false).setBackgroundDimAmount(0.5f).setContentView(R.layout.window_app_update_hint);
    }
    return instance;
}

public void showWindow(String desc, String url) {
    Button button = instance.getContentView().findViewById(R.id.update_button);
    button.setOnClickListener((view) -> {
        LogUtils.d("点击更新" + url);
        AppUpdateApi.downloadApp(this, url);

    });
    TextView viewById = instance.getContentView().findViewById(R.id.update_desc);
    viewById.setText(desc);
    show();
}
@NonNull
@Override
public Lifecycle getLifecycle() {
    return mLifecycle;
}

}`
