title: Android, build on Ubuntu fails due to aapt
body: <p>I am trying to build an Android project on a headless Ubuntu 14.04, but fail with the following error:</p>
  
  <p><code>&gt; A problem occurred starting process 'command '/Users/jenkins/AndroidSdk/build-tools/22.0.1/aapt''</code></p>
  
  <p>The stacktrace shows that the file has not been found, though the file is there. I googled it, and it turns out that this might happen if i try to execute a 32-bit file on a 64-bit architecture OS. However, it seems I have no control over which arch build tools are installed by <code>android sdk</code> utility. Is there any way I could get the 64 bit version?</p>
