title: Conversion to Dalvik format failed with error 1 with javax/net/SocketFactory.class
body: <p>Encounter this problem when trying to Build Project getting such output in console:</p>
  
  <pre><code>[2010-07-19 23:29:23 - myProject]
  trouble processing "javax/net/SocketFactory.class":
  [2010-07-19 23:29:23 - myProject] 
  Attempt to include a core VM class in something other than a core library.
  It is likely that you have attempted to include the core library from a desktop
  virtual machine into an application, which will most assuredly not work. If
  you really intend to build a core library -- which is only appropriate as
  part of creating a full virtual machine binary, as opposed to compiling an
  application -- then use the "--core-library" option to suppress this error
  message. If you go ahead and use "--core-library" but are in fact building
  an application, then please be aware that your build will still fail at some
  point; you will simply be denied the pleasure of reading this helpful error
  message.

  <p>I was looking for my project to use the package javax, not found, clean all also does not help. what I am doing wrong?</p>
  
  <p><strong>Update</strong></p>
  
  <p>Sorry guys, but I could not find good fix for that, I want to emphasize the fact, that i dont use <code>SocketFactory</code> class in my project at all! source code was not changed before this problem, and that's why i think that problem in eclipse or adt or something else, BUT if i use ant(generated by sdk) to build this project there is no problem!!!</p>
  
  <p>I solve this problem by removing Eclipse, Android SDK, Eclipse workspace, and just reinstall them, after this all works fine for now.</p>
  
  <p>Hope this will help someone.</p>
