title: Importing com.android.dx
body: <pre><code>import com.android.dx.Version;
  import com.android.dx.dex.DexFormat;
  import com.android.dx.dex.DexOptions;
  import com.android.dx.dex.cf.CfOptions;
  import com.android.dx.dex.cf.CfTranslator;

  import com.android.dx.dex.file.ClassDefItem;
  import com.android.dx.dex.file.DexFile;
  </code></pre>
  
  <p>These imports are not working. But I don't know why: I have the Android.jar (the one in <code>sdk/platforms/android-20</code>) in my eclipse build path. Why am I unable to import these?</p>
