title: [EDITED]Is Android Support Package have any debelity?
body: <p>Lately  I was using support package android like <code>actionbar activity</code> or <code>fragment activity</code> to build an app.  I combined many tutorial that don't use support package to my project, so the project can do thing that I need, but sadly, I had to overcome many errors, and that why this question fly in my head ...</p>
  
  <p>I try to learn how the support package works, the articles pretty much said that support package works the same as the main package(is that we call it? sorry, I don't know), the difference is the support package works for android prior to honeycomb ...</p>
  
  <p>And lastly is that okay to use both support package and main package together like using actionbar activity and fragment....</p>
  
  <p>Thanks </p>
