title: How to set the ANDROID_HOME environment variable?
body: <p>For Maven to work properly I need to set the ANDROID_HOME variable to point to my SDK directory. I suppose the directory I need to set it to is "/Users/kramer65/dev/adt-bundle-mac-x86_64-20130917/sdk".</p>
  
  <p>But my question: how do I set this variable?</p>
