title: jar file not working for imports in Eclipse
body: <p>I am following a tutorial from <a href="http://www.androidhive.info/2012/09/android-twitter-oauth-connect-tutorial/" rel="nofollow noreferrer">AndroidHive</a> on how to login to Twitter from my app. </p>
  
  <p>The tutorial uses the twitter4j library, so I download it from <a href="http://twitter4j.org/en/index.html#download" rel="nofollow noreferrer">here</a> and save the zip file to my desktop. In my project I drag the twitter4j zip file into my projects libs folder. Then I Refactor -> Rename the file from a zip to a jar (only changing the extension)</p>
  
  <p>However, when I want to import the classes into my project, it does not seem to be working. I try to do </p>
  
  <pre><code>import twitter4j.Twitter;
  </code></pre>
  
  <p>But this option is not available. See screen grab.
  Can anyone please tell me where I am going wrong with this?</p>
  
  <p>Also, as per the tutorial I have also just added the twitter4j-core file to the project but still imports wont seem to work.</p>
