title: public static variable or use putExtra method of intent class
body: <p>I have a general question here about performance, and which of which should I do and which I should not use.
  I am actually using in my App two activities, let us call "theFirst" and "theSecond" activity.</p>
  
  <p>In theFirst activity I have a public static object, in my case, its a list of a custom object made by me, called Conjunction.</p>
  
  <p>When I call the theSecond activity I want to get the content of this list.
  So should I use the public static variable ? is there any problem? There will be only one instance of theFirst activity right? So no problem using public static variable..? I guess.</p>
  
  <p>Or should I compute the entire list and put the information on a big String and send it to theSecond activity using the putExtra method?</p>
  
  <p>A good explanation on this would be very good and I would really appreciate it <code>:)</code></p>
