How to clean variables in an Activity?

In my Application when on pressing on the back button returning to previous activity, the variables are still set up and containing values, my question is how can I reset all variables in any activity, so to act when first launched?

If this helps, i'm having an app that contains three activities; In Activity 1: am putting Bundle.putExtras() some string to send to the next activity ... In Activity 2: also putting some strings in a bundle and sends it to Activity 3 ...

You can finish() your current activity after you call your second activity. This will clean variable in your ex activity.

Just initialize all variables on the onResume() method. That way, every time your activity comes into play, your data is wiped out.

Your non-static variables will be cleared and be reset to their defaults when you go back from your Activity.

Your static variable can be reset in the onDestroy() method of your Activity, although doing that defeats the purpose of making them static in the first place.

EDIT: I see you were talking about the previous Activity. In this case, just override the onResume() of your previous Activity to do the clearing of variables, although I fail to see why you would need to do that.
