Is onCreate called when an Activity object is created?

Question

Is onCreate called when a class object that extends activity is created? Or is it only called when an activity is started, for example over startActivity(...).

Answer 1

To answer you question, for a class that extends activity, if you try to instantiate that Activity by normal means ( MyActivity ma = new MyActivity(); ) the onCreate() method WILL NOT be called. Only if you start the Activity with an intent will the method be called.
