title: when I start Android studio I get this Error:(21, 76) error: cannot find symbol variable fab
body: <p>Im just newbie, and im starting with tutorials. I installed <code>Android studio 1.4</code> and I get this error message when it starts:</p>
  
  <pre><code>Error:(21, 76) error: cannot find symbol variable fab
  Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
  Compilation failed; see the compiler error output for details.
  </code></pre>
  
  <p>I'm running Windows 10, as I already said I'm using Android studio 1.4
  Does anybody have a clue what could be the issue?
  I've tried to search the web and forums but so far I didn't find anything helpful.</p>
  
  <p>Thank You so much.</p>
