title: I get 'Command Not Found' when I try to run Android Emulator on Mac OS X
body: <p>When I use the <a href="https://en.wikipedia.org/wiki/Terminal_%28OS_X%29" rel="noreferrer">Mac OS X Terminal</a> to navigate to the folder with my Android Emulator and type <code>emulator</code>, I get:</p>
  
  <blockquote>
    <p>command not found</p>
  </blockquote>
  
  <p>Here's what happens:</p>
  
  <pre><code>$ emulator
  -bash: emulator: command not found
  </code></pre>
  
  <p>How do I get it to work?</p>
