How do I run Android Fragment on Attach()?

After looking at the life cycle of the fragment, we override all on~~() functions and output them to Log.d.

, but onattach () is not seen as log.

"OnAttach() callback method is called after the fragment is added to activity," but I couldn't print the log.

Is there anything else I need to do if I want to see the on-Attach performance?

How can I see log taken with Logcat?
