Android, How to call onCreate() explicitly from other method?

Question

I want to call onCreate(Bundle cicici); from other method then i am getting "NullPointerException", so please guide me how can i call the onCreate() from another method().

    public void moreFriendsButtonClick(int id)
{
    contentId= id;
    onCreate(tempBundle);
}

Here i am passing int value, and

tempBundle=savedInstanceState;

and after that i am getting NullPointerException

Why do you need this? If you want to call some code that is inside your `onCreate` then move that code to some function named `onCreateHelper` and call both from your `onCreate` and from all other places you need. — inazaruk, Jun 27 '11 at 11:34
here i make i TabActivity class and one of tab have some buttons, and i want to click on that specific button and the Activity page regarding to that button, should be display into Tab contentView area (Frame Layout). if i am not doing like this then called Activity taking full screen... This is the reason.. so please guide me... — Vishesh Chandra, Jun 27 '11 at 12:58
in document they said, we should not call lifecycle methods directly. — neeraj t, Mar 13 '14 at 09:41

you should create the bundle again. savedInstanceState is local to onCreate method. try

Bundle tempBundle = new Bundle();
onCreate(tempBundle);

It should work.

This is what worked for me:

onCreate(new Bundle());
