<h2>SDK Contents</h2>
<h4>Development tools</h4>
<p>The SDK includes a full set of tools for developing and debugging application
code and designing an application UI. You can read about the tools in the <a
href="{@docRoot}guide/developing/tools/index.html">Dev Guide</a> and access them
in the <code><sdk>/tools/</code> directory.
<p>The tools package in this SDK includes updates from those provided in the
previous SDK. The tools use the same project structure as in the previous SDK
(Android 1.5). If you have application projects developed in the Android 1.5
SDK, you can migrate them to the latest SDK without modification. For more
information about how to migrate, see <a href="upgrading.html">Upgrading the
SDK</a>.
<h4 id="system_images">Android Platforms</h4>
<p>This SDK includes multiple Android platform versions that you can use to
develop applications. For each version, both a fully compliant Android library
and system image are provided. The table below lists the platform versions
included in this SDK. For more information about a platform version —
features, applications included, localizations, API changes, and so on —
see its Version Notes. </p>

<p>Note that you can use the Android SDK and AVD Manager to download other
platform versions into your development environment.</span>.
<h4 id="system_images">SDK Add-Ons</h4>
<p>An SDK add-on provides a development environment for an Android external
library or a customized (but fully compliant) Android system image. This SDK
includes the SDK add-ons listed below. The Android system API Level required by
the add-ons are noted.</p>

<h4>Sample Code and Applications</h4>
<p>You can look at a variety of tutorials and samples in the <a
href="{@docRoot}guide/samples/index.html">Dev Guide</a> and access the sample
code itself in the <code><sdk>/platforms/<platform>/samples/</code>
directory of the SDK package. Note the new location — the SDK now includes
multiple platform versions that you can develop against and each has its own
sample code directory. </p>
<p>For example, to view or build the samples available for the Android
1.6 platform (AVD target "Android 1.6"), you will find the samples in the
<code><sdk>/platforms/android-1.6/samples/</code> directory of the SDK
package. </p>
<h4>Documentation</h4>
<p>The SDK package includes a full set of local documentation. To view it, open
the <code><sdk>/documentation.html</code> file in a web browser. If you
are developing in an IDE such as Eclipse, you can also view the reference
documentation directly in the IDE. </p>
<p>The most current documentation is always available on the Android Developers
site:</p>
