static variable belongs to class not the object, and finish() or garbage collector affects object, therefore it got no influence on static variables. Please note that class does not equals object but object is instance of class.

Then please update your question with example of declaration of that variable and more information what `some time` exactly means (other words, what you do to to trigger this issue) – Marcin Orlowski Sep 01 '12 at 13:27
is it possible that null while my device is goes to in sleep mode ? – Youddh Sep 01 '12 at 13:32
I'd say that would be rather odd – Marcin Orlowski Sep 01 '12 at 13:34

No there is no effect on static variable by calling finish or gc. You can access those variable from other activity for the proof
