  <li>Here are the steps to install Java:

    <ol>

      <li><p>If you are running a 64-bit distribution on your development

      machine, you need to install additional packages first. For Ubuntu 13.10 (Saucy Salamander)

      <pre class="no-pretty-print">apt-get install ia32-libs</pre>

      </li>

      <li>Next, install Java: <pre class="no-pretty-print">apt-get install sun-java6-jdk</pre></li>

      <li>The Ubuntu package manager does not currently offer an Eclipse 3.7

      version for download, so we recommend that you download Eclipse from

      eclipse.org (<a

      href="http://www.eclipse.org/downloads/">http://www.eclipse.org/downloads/</a>).

      A Java or RCP version of Eclipse is recommended.</li>

      <li>Follow the steps given in previous sections to install the SDK

      and the ADT plugin. </li>
