<p class="note"><strong>Note: </strong>The Android <code>layoutopt</code> tool has been replaced by the {@code lint} tool beginning in ADT and SDK Tools revision 16. The {@code lint} tool reports UI layout performance issues in a similar way as <code>layoutopt</code>, and detects additional problems.</p>
<p>For more information about using {@code lint}, see <a href="{@docRoot}tools/debugging/improving-w-lint.html">Improving Your Code with lint</a> and the <a  href="{@docRoot}tools/help/lint.html">lint reference documentation</a>.</p>

<p><code>layoutopt</code> is a command-line tool that helps you optimize the
layouts and layout hierarchies of your applications.<p>

<p>This document is a reference to the available command line options. For more information and sample
output of the tool, see <a
href="{@docRoot}tools/debugging/debugging-ui.html#layoutopt">Optimizing layouts with
layoutopt</a>.</p>

<h3>Usage</h3>

<p>To run <code>layoutopt</code> against a given list of layout resources:</p>

<pre>layoutopt &lt;file_or_directory&gt; ...</pre>

<p>For example:</p>

<pre>$ layoutopt res/layout-land</pre>
<pre>$ layoutopt res/layout/main.xml res/layout-land/main.xml</pre>
