  Android Packaging Problem
  </code></pre>
  
  <p>I've never worked with Java or eclipse before, I'm following <a href="http://www.vogella.de/articles/Android/article.html" rel="noreferrer">this introductory guide</a> and all searches via google return no helpful results. I'm guessing the problem is I have built Android stuff with eclipse properly but I have no idea, I followed this guide to the letter and everything went as it explains it should. </p>
  
  <p><img src="https://i.stack.imgur.com/uwW6v.jpg" alt="Here is what I have compiled">
  Any ideas what caused this problem, or is it specific to the guide? If so I'll post on their help page. </p>
  
  <p>I have tried doing project -> source -> clean up, but that didn't fix anything. </p>
  
  <p>Edit:</p>
  
  <p>I went to Project -> Android tools -> Dex bytecode and it reported:</p>
  
  <pre><code>DexDump: missing classex.dex for project. Please compile first.
  </code></pre>
  
  <p>So I guess that's my problem! Not sure how to solve though.</p>
