@jd:body
<p>The sections below describe other tools that you can use when building
Android applications. </p>
<p>All of the tools are included in the Android SDK and are accessible from the
<code><sdk>/tools/</code> directory.</p>

<h2 id="android">android</h2>
<p>{@code android} is an important development tool that lets you:</p>
<ul>
<li>Create, delete, and view Android Virtual Devices (AVDs). See
<a href="{@docRoot}guide/developing/tools/avd.html">Android Virtual Devices</a>.</li>
<li>Create and update Android projects. See
<a href="{@docRoot}guide/developing/other-ide.html">Developing in Other IDEs</a>.</li>
<li>Update your Android SDK with new platforms, add-ons, and documentation. See
<a href="{@docRoot}guide/developing/updating-sdk.html">Updating Your SDK</a>.</li>
</ul>
<p>If you develop in Eclipse with the ADT plugin, you can perform
these tasks directly from the IDE. To create
Android projects and AVDs from Eclipse, see <a href="{@docRoot}guide/developing/eclipse-adt.html">Developing
In Eclipse</a>. To update your SDK from Eclipse, see
<a href="{@docRoot}guide/developing/updating-sdk.html">Updating Your SDK</a>.
</p>
<a name="mksdcard"></a>
<h2>mksdcard</h2>
<p>The mksdcard tool lets you quickly create a FAT32 disk image that you can
load in the emulator, to simulate the presence of an SD card in the device.
Here is the usage for mksdcard:</p>
<pre>mksdcard [-l label] <size>[K|M] <file></pre>
<p>The table below lists the available options/arguments</p>
<table>
<tr>
<th>Argument</th>
<th>Description</th>
</tr>
<tr>
<td><code>-l</code></td>
<td>A volume label for the disk image to create. </td>
</tr>
<tr>
<td><code>size</code></td>
<td>An integer that specifies the size (in bytes) of disk image to create.
You can also specify size in kilobytes or megabytes, by appending a "K" or "M" to
<size>. For example, <code>1048576K</code>, <code>1024M</code>.</td>
</tr>
<tr>
<td><code>file</code></td>
<td>The path/filename of the disk image to create. </td>
</tr>
</table>
<p>Once you have created the disk image file, you can load it in the emulator at
startup using the emulator's -sdcard option. For more information, see
<a href="{@docRoot}guide/developing/tools/emulator.html">Android Emulator</a>.</p>
<pre>emulator -sdcard <file></pre>
<a name="dx"></a>
<h2>dx</h2>
<p>The dx tool lets you generate Android bytecode from .class files. The tool
converts target files and/or directories to Dalvik executable format (.dex) files,
so that they can run in the Android environment. It can also dump the class files
in a human-readable format and run a target unit test. You can get the usage and
options for this tool by using <code>dx --help</code>.</p>
