@jd:body

<p>SDK Tools is a downloadable component for the Android SDK. It includes the
complete set of development and debugging tools for the Android SDK. </p>

<p>If you are new to the Android SDK, the <a 
href="{@docRoot}sdk/index.html">SDK starter package</a> installs the
latest revision of the SDK Tools in the <code>&lt;sdk&gt;/tools</code> directory.</p>

<p>If you are already using the SDK and you want to update to the latest version
of the SDK Tools, use the <em>Android SDK and AVD Manager</em> to get the
update, rather than downloading a new SDK starter package. For more information
about how to update, see <a
href="{@docRoot}sdk/adding-components.html#UpdatingComponents">Updating SDK
Components</a>. </p>

<h2 id="notes">Revisions</h2>

<p>The sections below provide notes about successive releases of
the SDK Tools, as denoted by revision number. To determine what revision of the SDK
Tools you are using, refer to the "Installed Packages" listing in the Android SDK
and AVD Manager. </p>

highly recommend updating your ADT Plugin to 0.9.8.</p>

<dt>General notes:</dt>
<dd>
<ul>
<li>Added support for library projects that depend on other library projects.</li>
<li>Adds support for aidl files in library projects.</li>
<li>Adds support for extension targets in Ant build to perform tasks between the
normal tasks: <code>-pre-build</code>, <code>-pre-compile</code>, and
<code>-post-compile</code>.</li>
<li>Adds support for "headless" SDK update. See <code>android -h update sdk</code>
for more information.</li>

SDK Tools, Revision 6</a> <em>(May 2010)</em>
  <div class="toggleme">

<dl>
<dt>Dependencies:</dt>
<dd>
<p>If you are developing in Eclipse with ADT, note that SDK Tools r6 is
designed for use with ADT 0.9.7 and later. After installing SDK Tools r6, we
highly recommend updating your ADT Plugin to 0.9.7.</p>
</dd>

<dt>Library projects:</dt>
<dd>
<p>The SDK Tools now support the use of <em>library projects</em> during
development, a capability that lets you store shared Android application
code and resources in a separate development project. You can then reference the
library project from other Android projects and, at build time, the tools
compile the shared code and resources as part of the dependent applications.
More information about this feature is available in the <a
href="{@docRoot}guide/developing/other-ide.html#libraryProject">Developing 
in Other IDEs</a> document.</p>
<p>If you are developing in Eclipse, <a href="eclipse-adt.html">ADT 0.9.7</a>
provides the equivalent library project support.</p>
