What does ViewRootlmpl.mAttachInfo means?

Hello, I am getting strange memory leak on my app. How should I solve it and what can cause it? This leaks occurs before I want to create Fragment
**Called onCreate**
private void initRecyclerView()
recyclerView = findViewById(R.id.documentsRecyclerView);
recyclerView.addItemDecoration(new DividerItemDecoration(this,
DividerItemDecoration.VERTICAL));
LinearLayoutManager manager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(manager);
TestRecyclerViewAdapter adapter = new TestRecyclerViewAdapter(
Test.getValues(), this);
recyclerView.setAdapter(adapter);
@Override
protected void onDestroy()
if (recyclerView != null)
recyclerView.setAdapter(null);
recyclerView.setLayoutManager(null);
recyclerView.addItemDecoration(null);
recyclerView = null;
super.onDestroy();
**I add fragment observing LiveData and set layout Container as root Activity layout**
private void addTestFragment()
TestFragment test = new TestFragment();
getSupportFragmentManager().
beginTransaction().add(R.id.main_activity_layout, test, TEST_FRAGMENT)
.commit();

An image of the cause without the code is just as useless as the code without the error.

@TheWanderer I can't share code here, but basically it should be alright. I follow all required principles.
