Question

I’ve got an ANDROID_HOME variable set:

$ set | grep ANDROID_HOME
ANDROID_HOME=/Users/jenkins/android-sdk-macosx

However when I start ruby, it’s not seeing it:

$ irb
1.9.3p194 :001 > ENV["ANDROID_HOME"]
 => nil 

It is seeing other variables however:

1.9.3p194 :002 > ENV["HOME"]
 => "/Users/jenkins" 

The ANDROID_HOME variable is defined in my ~/.profile .

Any thoughts? Thanks!

You need to export the variable otherwise it won’t be visible in any child processes:

export

Set an environment variable. Mark each name to be passed to child 
processes in the environment.

Syntax
      export [-fn] [-p] [name[=value]]

So in your .profile:

export ANDROID_HOME=${HOME}/android-sdk-macosx
