title: ANDROID_HOME location not found by NativeScript
body: <p>I have problem with ANDROID_HOME on a Mac OS. I'm trying to add platform android to NativeScript app and I have this message:</p>
  
  <pre><code>The ANDROID_HOME environment variable is not set or it points
  to a non-existent directory.
  You will not be able to perform any build-related operations for Android.
  </code></pre>
  
  <p>I've checked if I had SDK and yes, I have. Android Studio shows me this:</p>
  
  <pre><code>/Users/myuser/Library/Android/sdk
  </code></pre>
  
  <p>I found that I also have android sdk in <code>/usr/local/Cellar/android</code></p>
  
  <p>Before I have Xamarin and Homebrew which I think installs Android SKD itself. Maybe that is the problem?</p>
