title: Android Development - Conversion to Dalvik format failed with error 1
body: <p>So I'm dipping my toes into this area for the first time - i followed instructions to install the android SDK and eclipse plug in. I created a blank new android project and I get the following build errors:</p>
  
  <pre><code>[2011-01-08 16:34:55 - xxx]: Dxno classfiles specified
  [2011-01-08 16:34:55 - xxx] Conversion to Dalvik format failed with error 1
  </code></pre>
  
  <p>I've googled the problem and tried to clean and rebuild, or hitting F5 on the project in the explorer but the issue remains. I've verified the build paths and the libraries to make sure only Android 2.3 is there but still get this issue. </p>
  
  <p>I have also tried to load a sample project and I get the same error.</p>
  
  <p>Any ideas?</p>
