title: What's the difference between opening an app from the applications screen and the recently used apps list? (android
body: <p>Can anyone tell me what the difference is between opening an app from the applications screen and opening it from that recently used apps list that pops up when you long-press the home button?</p>
  
  <p>I didn't even know that recently used list existed until a friend managed to break my app by launching it from there.  He tried twice and got the same force quit, but when he launched it from the applications screen it opened fine.</p>
  
  <p>The error log told me that a nullPointerException occurred in the getCount method on my ArrayAdaptor for my ListView.  </p>
  
  <p>Anyway I just wondered if there was a difference that I need to know about and adapt my code to deal with?</p>
