根据分析结果，有一个名为`NetSpeedManager`的类实例被保留，其中包含一个`VideoStatusView`对象实例，该对象引用了一个已销毁的`AlbumActivity`实例，并导致该`AlbumActivity`实例无法被垃圾回收器回收。

解决方法是在`AlbumActivity`的`onDestroy()`方法中取消对该`VideoStatusView`对象实例的引用，例如：

@Override
protected void onDestroy() {
    super.onDestroy();
    videoStatusView.setActivityDestroyed(true); // 设置标志位
    videoStatusView = null; // 取消引用
}

在`VideoStatusView`中添加一个标志位`activityDestroyed`，并在其`onDetachedFromWindow()`方法中检查该标志位，如果为`true`则取消对`mContext`的引用，例如：

public class VideoStatusView extends FrameLayout {
    private boolean activityDestroyed = false; // 标志位

    // ...

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        if (activityDestroyed) {
            mContext = null; // 取消引用
        }
    }

    public void setActivityDestroyed(boolean destroyed) {
        activityDestroyed = destroyed;
    }
}
