title: launching another activity what happens to arraylist in previous activity
body: <p>I have an activity lets call it activity A which on creation downloads some data from a database. The data is stored in a custom ArrayList called myData.</p>
  
  <p>When a user clicks on a button another activity called B is launched. Activity A passes some data to Activity B which I can do by making my class implement Parcelable. </p>
  
  <p>My understanding when Activity B is lanuched that Activity A will be in either the onPause or onStop state. My question is will my arraylist myData still exist when Activity B is closed and the focus goes back to Activity A? If not how can I store this data?</p>
