title: Android Library project out of sync in Eclipse
body: <p>I have an Android Library project with some Activities and Views, referenced by an Android Application project. The application project has a "linked" folder marked [Android Library] with the sources of my library project.</p>
  
  <p>One thing that seems strange to me, is that the same source file can be opened twice, from the linked folder and from the original library folder. This often results in files being out on sync, and all sorts of nasty things happening.</p>
  
  <p>Any idea of what's going wrong? Thanks in advance!</p>
