Java 每当我关闭任何片段时，都会出现未知内存泄漏

当我关闭任何片段时，我正在制作博客应用程序，并且内存泄漏……我试图找到答案，一些人说在onDestroyView或onDestroy上取消您的视图引用（我尝试了这两种方法，但都不起作用），然后我只创建了没有任何视图的空白片段（只有蓝色背景），即使我关闭了BlankFragment，我仍然得到相同的内存泄漏…下面是我用来添加空白片段的代码

 Fragment blankFragment = new BlankFragment();
 FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
 transaction.hide(userProfileFragment);     //hiding userProfileFragment which is current fragment
 transaction.add(R.id.frame_container, blankFragment,"blank");
 transaction.addToBackStack(null);
 transaction.commit();

在我关闭一个不包含任何视图的空白片段之后，我在leak Canary中得到了以下内存泄漏警告

┬───

UserProfile\u Fragment.transaction可能是泄漏的原因，您不应该将片段事务保存在内存中，因为它会保留空白片段
