android - How to clean variables in an Activity? -


in application when on pressing on button returning previous activity, variables still set , containing values, question how can reset variables in activity, act when first launched?

if helps, i'm having app contains 3 activities; in activity 1: putting bundle.putextras() string send next activity ... in activity 2: putting strings in bundle , sends activity 3 ...

your non-static variables cleared , reset defaults when go activity.

your static variable can reset in ondestroy() method of activity, although doing defeats purpose of making them static in first place.

edit: see talking previous activity. in case, override onresume() of previous activity clearing of variables, although fail see why need that.
