Is onCreateOptionsMenu() of action bar called before or after the onStart() of activity?

An Android activity goes through six major lifecycle stages or callbacks. These are: onCreate() , onStart() , onResume() , onPause() , onStop() , and onDestroy() . The system invokes each of these callbacks as an activity enters a new state.
onCreate() method calls the setContentView() method to set the view corresponding to the activity. By default in any android application, setContentView point to activity_main. xml file, which is the layout file corresponding to MainActivity.
onPause() The system calls this method as the first indication that the user is leaving your activity (though it does not always mean the activity is being destroyed); it indicates that the activity is no longer in the foreground (though it may still be visible if the user is in multi-window mode).
onResume() is called at the start of the active lifetime; more specifically, it is called at the start of the active lifetime; more specifically it is called after onRestoreInstanceState(Bundle), onRestart(), or onPause() for your activity to start interacting with the user.
onStart() is called first. (I tried putting log messages in the methods).
