Which method is called first when creating a fragment in Android?

The very first method called when creating a fragment in Android is the onAttach(Context context) method. This method is called when the fragment is attached to an activity, and it is the starting point of the fragment's lifecycle.

Example:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    // Here you can get a reference to the activity or perform initial setup
}
