title: adb server is out of date. killing
body: <p>I'm creating my first react-native project with this tutorial: <a href="http://facebook.github.io/react-native/" rel="noreferrer">http://facebook.github.io/react-native/</a></p>
  
  <p>When it comes to executing code and running <code>react-native run-android</code> I am getting:</p>
  
  <pre><code>adb server is out of date.  killing...
  * daemon started successfully *
  </code></pre>
  
  <p>And the app on the android device is obviously not working.</p>
  
  <p>I've reinstalled the SDK, tried to  <code>adb kill-server</code> and <code>adb start-server</code>, but nothing seems to work</p>
  
  <p>I'm using Android 4.4 and Ubuntu 14.04</p>
