Why is onCreate() in Activity protected?

Question

Why is the onCreate() in Activity protected?

or I should ask: why does it work?

Protected method can only be called in the inside of the class itself or it\'

Answer 1

the onCeate() is protected so to avoid calling of it from the activity object.

MyActivity activity = new MyActivity();
activity.onCreate(args);  // which doesn't make sense because activity is not yet created

Since this method is only called when the activity gets created, calling it yourself will most probably give you a nullpointerException because the activity is not yet created.
