title: Command aapt is not found
body: <p>I wanted to use the aapt command on a Mac with the android sdk (folder /build-tools/24.0.1). But whenever I try to use the command I get the message that the command is not found (aapt/aapt2). This doesn't work neither in the Terminal nor in Android Studio.</p>
  
  <p>If I list the available commands in the 24.0.1. folder in the Terminal, there is a star sign next to both commands, which is described as: </p>
  
  <pre><code>A star (*) next to a name means that the command is disabled.
  </code></pre>
  
  <p>How can I enable these commands again? Updating the build-tools didn't help.</p>
