Why is onCreateView not executed after the fragment is added to the activity?

Question

Java

Here I am adding a fragment to the activity container:

fragmentManager.beginTransaction()
                .add(R.id.preview, previewFragment)
                .commit();
 Log.d("app", "2");

In fact, after adding a fragment, a call to onCreateView should occur:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.frament_photo_preview, container, false);
        Log.d("app", "0");
        return v;
}

And in the logs it should output:
app: 0
app: 2
But it outputs:
app: 2
app: 0
Is it because transactions associated with fragments are asynchronous? Or why?
