title: Adding Google-play-services crashes aapt.exe
body: <p>I'm trying to use google maps v2 for android by adding the google-play-services to my app as a library. Everytime I set a reference to the library I get windows dialog with the message that aapt.exe has crashed. And after I've set a reference to the library all my source files get errors. R.java in my gen folder gets deleted.
  Console is giving this message</p>
  
  <p><code>[google-play-services_lib] R.java was modified manually! Reverting to generated version!</code></p>
  
  <p>After deleting the reference to the google-play-services library the errors disappear. I'm using Eclipse Helio with SDK tools rev 22.0.1</p>

  <p>Can someone help me out?</p>
