title: When to use FragmentManager::putFragment and getFragment
body: <p>I've got an application that uses fragments and I was playing around with how to use the same fragment in an Activity with a dual pane and an Activity as a stand alone. Still not sure on the best method for completing this but I noticed the FragmentManager has a putFragment and getFragment function. What confuses me is that you have to provide a Bundle as parameter to both get and put functions. How can separate Activities have the same Bundle? Obviously you could pass the Bundle as a parameter but at that point I feel like you're just making a mess of things. </p>
  
  <p>So what is a good scenario for using getFragment and putFragment? Please include the Bundle parameter explanation.</p>
