title: android-support-v4.jar dependency error
body: <p>I just created a new blank Android project with <code>minsdk</code> as 2.2 in the latest Eclipse Luna.Eclipse automatically added an <code>android-support--v4.jar</code> in the libs folder of the project. This is causing an error in the console :</p>
  
  <pre><code>Found 2 versions of android-support-v4.jar in the dependency list,
  but not all the versions are identical (check is based on SHA-1 only at this time).
  All versions of the libraries must be the same at this time.
  Versions found are:
  Path: /home/faizal/DEV/ADT workspace/myNewProject/libs/android-support-v4.jar
      Length: 758727
      SHA-1: efec67655f6db90757faa37201efcee2a9ec3507
  Path: /home/faizal/DEV/ADT workspace/appcompat_v7/libs/android-support-v4.jar
      Length: 648327
      SHA-1: ded9acc6a9792b8f1afc470f0c9cd36d178914cd
  Jar mismatch! Fix your dependencies
  </code></pre>
  
  <p>This is because I also have an appcompat_v7 support library project, which I am using for another project and was created by an older Eclipse(i think it was Juno..it was part of the ADT bundle).</p>
  
  <p>I know the solution is to remove one of the jars, but which one and why?</p>
