title: Will calling finish() from an activity free up my memory space?
body: <p>I have an activity which uses considerable amount of memory in my app. So whenever the user switches over from that activity to some other activity, I am trying to call finish() to stop that activity. </p>
  
  <p>My question is, will calling finish() from that activity free up memory space or just finishes that activity without cleaning the memory used by that particular activity?</p>
  
  <p>Any help is much appreciated..   </p>
