		<p>The Android SDK is composed of modular packages that you can download separately using
		the Android SDK Manager. For example, when the SDK Tools are updated or a new version of
		the Android platform is released, you can use the SDK Manager to quickly download them to
		your environment. Simply follow the procedures described in <a
		href="{@docRoot}sdk/installing/adding-packages.html">Adding Platforms and Packages</a>.</p>

		<p>There are several different packages available for the Android SDK. The table below describes
		most of the available packages and where they're located once you download them.</p>


		<h2 id="Packages">Available Packages</h2>


		<table>
		<tr><th>Package</th><th>Description</th><th>File Location</th></tr>
		<tr>
		<td><a href="{@docRoot}tools/sdk/tools-notes.html">SDK Tools</a></td>
		<td>Contains tools for debugging and testing, plus other
		utilities that are required to develop an app. If you've just installed the SDK starter package,
		then you already have the latest version of this package. Make sure you keep this up to date.</td>
		<td>{@code <sdk>/tools/}</td></tr>
		<tr><td>SDK Platform-tools</td>
		<td>Contains platform-dependent tools for developing and debugging
		your application. These tools support the latest features of the Android platform and are typically
		updated only when a new platform becomes available. These tools are always backward compatible with
		older platforms, but you must be sure that you have the latest version of these tools when you
		install a new SDK platform.</td>
		<td>{@code <sdk>/platform-tools/}</td>
		</tr>

		<tr>
		<td>Documentation</td>
		<td>An offline copy of the latest documentation for the Android
		platform APIs.</td>
		<td>{@code <sdk>/docs/}</td>
		</tr>
		<tr><td>SDK Platform</td>
		<td>There's one SDK Platform available for each version of Android. It includes an {@code
		android.jar} file with a fully compliant Android library. In order to build an Android app, you must
		specify an SDK platform as your build target.</td>
		<td>{@code <sdk>/platforms/<android-version>/}</td>
		</tr>
		<tr>
		<td>System Images</td>
		<td>Each platform version offers one or more different system images (such as for ARM
		and x86). The Android emulator requires a system image to operate. You should always test your
		app on the latest version of Android and using the emulator with the latest system image is a
		good way to do so.</td>
		<td>{@code <sdk>/platforms/<android-version>/}</td>
		</tr>
		<tr>
		<td>Sources for Android SDK</td>
		<td>A copy of the Android platform source code that's useful for
		stepping through the code while debugging your app.</td>
		<td>{@code <sdk>/sources/}</td>
		</tr>
		<tr>
		<td><a href="{@docRoot}tools/samples/index.html">Samples for SDK</a></td>
		<td>A collection of sample apps that demonstrate a variety of the
		platform APIs. These are a great resource to browse Android app code. The API Demos app in
		particular provides a huge number of small demos you should explore.</td>
		<td>{@code <sdk>/platforms/<android-version>/samples/}</td>
		</tr>
		<tr>
		<td><a href="http://developers.google.com/android">Google APIs</a></td>
		<td>An SDK add-on that provides both a platform you can use to develop an app
		using special Google APIs and a system image for the emulator so you can test your app using the
		Google APIs.</td>
		<td>{@code <sdk>/add-ons/}</td>
		</tr>

		<tr>
		<td><a href="{@docRoot}tools/support-library/index.html">Android Support</a></td>
		<td>A static library you can include in your app sources in order to use powerful
		APIs that aren't available in the standard platform. For example, the support library
		contains versions of the {@link android.support.v4.app.Fragment} class that's compatible with
		Android 1.6 and higher (the class was originally introduced in Android 3.0) and the {@link
		android.support.v4.view.ViewPager} APIs that allow you to easily build a side-swipeable UI.</td>
		<td>{@code <sdk>/extras/android/support/}</td>
		</tr>
		<tr>
		<td><a href="{@docRoot}google/play/billing/index.html">Google Play Billing</a></td>
		<td>Provides the static libraries and samples that allow you to
		integrate billing services in your app with Google Play.</td>
		<td>{@code <sdk>/extras/google/}</td>
		</tr>
		<tr>
		<td><a href="{@docRoot}google/play/licensing/index.html">Google Play Licensing</a></td>
		<td>Provides the static libraries and samples that allow you to perform license verification for
		your app when distributing with Google Play.</td>
		<td>{@code <sdk>/extras/google/}</td>
		</tr>
		</table>

		<p>The above table is not comprehensive and you can <a
		href="#AddingSites">add new sites</a> to download additional packages from third-parties.</p>

		<p>In some cases, an SDK package may require a specific minimum revision of
		another package or SDK tool. For example, there may be a dependency between the ADT Plugin for
		Eclipse and
		the SDK Tools package. When you install the SDK Tools
		package, you should also upgrade to the required version of ADT (if you
		are developing in Eclipse). In this case, the major version number for your ADT plugin should
		always match the revision number of your SDK Tools (for example, ADT 8.x requires SDK Tools r8).
		</p>

		<p>The development tools will notify you with debug warnings if there is dependency that you need to
		address. The Android SDK Manager also enforces dependencies by requiring that you download any
		packages that are needed by those you have selected.</p>





		<h2 id="AddingSites">Adding New Sites</h2>

		<p>By default, <strong>Available Packages</strong> displays packages available from the
		<em>Android Repository</em> and <em>Third party Add-ons</em>. You can add other sites that host
		their own Android SDK add-ons, then download the SDK add-ons
		from those sites.</p>

		<p>For example, a mobile carrier or device manufacturer might offer additional
		API libraries that are supported by their own Android-powered devices. In order
		to develop using their libraries, you must install their Android SDK add-on, if it's not already
		available under <em>Third party Add-ons</em>. </p>

		<p>If a carrier or device manufacturer has hosted an SDK add-on repository file
		on their web site, follow these steps to add their site to the Android SDK
		Manager:</p>

		<ol>
		<li>Select <strong>Available Packages</strong> in the left panel.</li>
		<li>Click <strong>Add Add-on Site</strong> and enter the URL of the
		<code>repository.xml</code> file. Click <strong>OK</strong>.</li>
		</ol>
		<p>Any SDK packages available from the site will now be listed under a new item named
		<strong>User Add-ons</strong>.</p>




		<h2 id="troubleshooting">Troubleshooting</h2>

		<p><strong>Problems connecting to the SDK repository</strong></p>

		<p>If you are using the Android SDK Manager to download packages and are encountering
		connection problems, try connecting over http, rather than https. To switch the
		protocol used by the Android SDK Manager, follow these steps: </p>

		<ol>
		<li>With the Android SDK Manager window open, select "Settings" in the
		left pane. </li>
		<li>On the right, in the "Misc" section, check the checkbox labeled "Force
		https://... sources to be fetched using http://..." </li>
		<li>Click <strong>Save & Apply</strong>.</li>
		</ol>

		<p>The Android SDK separates tools, platforms, and other components into packages you can
		download using the Android SDK Manager. The original
		SDK package you've downloaded includes only the SDK Tools. To develop an Android app,
		you also need to download at least one Android platform and the latest SDK Platform-tools.</p>

		<ol>
		<li>Launch the SDK Manager.
		<p>If you've used the Windows installer to install the SDK tools, you should already have the
		Android SDK Manager open. Otherwise, you can launch the Android SDK Manager in one of the following
		ways:</p>

		By default, the Android SDK does not include everything you need to start developing.
		The SDK separates tools, platforms, and other components into packages you can
		download as needed using the
		<a href="{@docRoot}tools/help/sdk-manager.html">Android SDK Manager</a>.
		So before you can start, there are a few packages you should add to your Android SDK.</p>

		<p>To start adding packages, launch the Android SDK Manager in one of the following ways:</p>
		<ul>
		<li>On Windows, double-click the <code>SDK Manager.exe</code> file at the root of the Android

		@jd:body


		<p>The ADT Bundle provides everything you need to start developing apps, including
		a version of the Eclipse IDE with built-in <b>ADT (Android Developer Tools)</b> to
		streamline your Android app development.
		If you haven't already, go download the <a href="{@docRoot}sdk/index.html"
		>Android ADT Bundle</a>. (If you downloaded the SDK Tools only, for use with an
		existing IDE, you should instead read
		<a href="{@docRoot}sdk/installing/index.html">Setting Up an Existing IDE</a>.)</p>

		<h3>Install the SDK and Eclipse IDE</h3>
		<ol>
		<li>Unpack the ZIP file
		(named {@code adt-bundle-<os_platform>.zip}) and save it to an appropriate location,
		such as a "Development" directory in your home directory.</li>
		<li>Open the {@code adt-bundle-<os_platform>/eclipse/} directory and launch
		<strong>eclipse</strong>.</li>
		</ol>

		<p>That's it! The IDE is already loaded with the Android Developer Tools plugin and
		the SDK is ready to go. To start developing, read <a href="{@docRoot}training/basics/firstapp/index.html"
		>Building Your First App</a>.</p>

		<p class="caution"><strong>Caution:</strong> Do not move any of the files or directories
		from the {@code adt-bundle-<os_platform>} directory. If you move the {@code eclipse}
		or {@code sdk} directory, ADT will not be able to locate the SDK and you'll
		need to manually update the ADT preferences.</p>

		<h3>Additional information</h3>

		<p>As you continue developing apps, you may need to install additional versions
		of Android for the emulator and other packages such as the library for
		Google Play In-app Billing. To install more packages, use
