title: Android: The type java.lang.Enum cannot be resolved
body: <p>I downloaded Android's Browser project (from git) and imported it to Eclipse. I cannot build it however because of the following error:</p>
  
  <blockquote>
    <p>The type java.lang.Enum cannot be
    resolved. It is indirectly referenced
    from required .class files</p>
  </blockquote>
  
  <p>Now... this is a development environment that has been working very well for other projects:</p>
  
  <ol>
  <li>Windows 7 Ultimate 64-bit.</li>
  <li>JDK 64-bit (jdk-6u23-windows-x64.exe installed.)</li>
  <li>Eclipse Classic 3.6 64-bit (eclipse-SDK-3.6.1-win32-x86_64.zip)</li>
  <li>Android 2.3 SDK Starter Package</li>
  </ol>
  
  <p>So I am not sure where the problem could lie.</p>
  
  <p>How do I solve this?</p>
