title: android is not recognized as an internal or external command [how to install android command]
body: <p>I am trying to convert Volley to a jar file. However a step in the guide has me input into the command prompt:</p>
  
  <p>"android update project -p .</p>
  
  <p>ant jar "</p>
  
  <p>but I get that android is not a command. I have never used this command before today and the guide assumes that it is already on my system. Can someone explain how to install and use the "android" command</p>
