title: aapt not found under the right path
body: <p>I just updated ADT, than the SDK and now I have in only one project the issue, that my aapt isn't found</p>
  
  <pre><code>Error executing aapt. Please check aapt is present at /opt/android/platform-tools/aapt
  </code></pre>
  
  <p>The path is correct, I checked twice and more times.</p>
  
  <pre><code>-rwxrwxrwx 1 martin martin 3,5M 2010-12-08 10:41 /opt/android/platform-tools/aapt
  </code></pre>
  
  <p>I can start aapt via console, the permissions are 777, I restarted eclipse, closed/reopened the project, restarted adb and finally my Ubuntu.</p>
  
  <p>Some ideas why this might happen only at one project?</p>
