title: adding $ANDROID_HOME/tools to $Path in windows
body: <p>I'm trying to run this code:</p>
  
  <pre><code>cd google-play-services_lib
  android update project -p .
  ant debug
  </code></pre>
  
  <p>from this <a href="https://github.com/xamarin/monodroid-samples/tree/master/MapsAndLocationDemo_v2#prequisites" rel="nofollow noreferrer">tutorial</a>. I installed <code>ant</code> using <a href="http://code.google.com/p/winant/" rel="nofollow noreferrer">winant</a>, but regarding Android, I can not add this to path.</p>
  
  <p>I tried adding the variable like this screen shot, but it did not help me. How can I add this?</p>

  <p>I'm not sure what is the relation between <code>android</code> command and the <code>android_home/tools</code> folder. I can not find any <code>android.exe</code> file in the <code>android_home/tools</code> folder. Maybe I should try another solution to run this.</p>
  
  <p><strong>EDIT</strong>
  When I change the variable base on Tom's reply now the result is:
