Run code on first OnCreate only

Question

I have a piece of code that I only want to run the very first time a particular OnCreate() method is called (per app session), as opposed to every time the activity is created. Is there a way to do this in Android?

Answer 1

use static variable.

static boolean checkFirstTime;

Answer 2

protected void onCreate(Bundle savedInstanceState) has all you need.

If savedInstanceState == null then it is the first time.

Hence you do not need to introduce extra -static- variables.
