body: <p>Err... I'm trying to run the "FloatingActionButtonBasic" example on my android device, and getting this error... Is it possible to downgrade my android studio to that old api? What should I do?</p>
  
  <p>And I want to mention, ActionBarCompat-Basic is running without problems, somehow.</p>
