<p>The Android SDK separates tools, platforms, and other components into packages you can
|
|
download using the SDK Manager.</p>
|
|
|
|
<p>You can launch the SDK Manager in one of the following ways:</p>
|
|
<ul>
|
|
<li>From Eclipse (with <a href="{@docRoot}tools/help/adt.html">ADT</a>),
|
|
select <strong>Window</strong> > <strong>Android SDK Manager</strong>.</li>
|
|
<li>On Windows, double-click the <code>SDK Manager.exe</code> file at the root of the Android
|
|
SDK directory.</li>
|
|
<li>On Mac or Linux, open a terminal and navigate to the <code>tools/</code> directory in the
|
|
Android SDK, then execute <code>android sdk</code>.</li>
|
|
</ul>
|
|
|
|
<p>You can select which packages you want to download by toggling the checkboxes on the left, then
|
|
click <strong>Install</strong> to install the selected packages.</p>

<p class="img-caption"><strong>Figure 1.</strong> The Android SDK Manager shows the

SDK packages that are available, already installed, or for which an update is available.</p>
|
|
|
|
|
|
<h2 id="Recommended">Recommended Packages</h2>
|
|
|
|
<p>Here's an outline of the packages required and those we recommend you use:
|
|
</p>
|
|
|
|
<dl>
|
|
<dt>SDK Tools</dt>
|
|
<dd><strong>Required.</strong> Your new SDK installation already has the latest version. Make sure
|
|
you keep this up to date.</dd>
|
|
<dt>SDK Platform-tools</dt>
|
|
<dd><strong>Required.</strong> You must install this package when you install the SDK for
|
|
the first time.</dd>
|
|
<dt>SDK Platform</dt>
|
|
<dd><strong>Required.</strong>You must download <em>at least one platform</em> into your
|
|
environment so you're able to compile your application. In order to provide the best user experience
|
|
on the latest devices, we recommend that you use the latest platform version as your build target.
|
|
You'll still be able to run your app on older versions, but you must build against the latest
|
|
version in order to use new features when running on devices with the latest version of Android.
|
|
<p>To get started, download the latest Android version, plus the lowest version you plan
|
|
to support (we recommend Android 2.2 for your lowest version).</p></dd>
|
|
<dt>System Image</dt>
|
|
<dd>Recommended. Although you might have one or more Android-powered devices on which to test
|
|
your app, it's unlikely you have a device for every version of Android your app supports. It's
|
|
a good practice to download system images for all versions of Android your app supports and test
|
|
your app running on them with the <a href="{@docRoot}tools/devices/emulator.html">Android emulator</a>.</dd>
|
|
<dt>Android Support</dt>
|
|
<dd>Recommended. Includes a static library that allows you to use some of the latest
|
|
Android APIs (such as <a href="{@docRoot}guide/components/fragments.html">fragments</a>,
|
|
plus others not included in the framework at all) on devices running
|
|
a platform version as old as Android 1.6. All of the activity templates available when creating
|
|
a new project with the <a href="{@docRoot}tools/sdk/eclipse-adt.html">ADT Plugin</a>
|
|
require this. For more information, read <a
|
|
href="{@docRoot}tools/extras/support-library.html">Support Library</a>.</dd>
|
|
<dt>SDK Samples</dt>
|
|
<dd>Recommended. The samples give you source code that you can use to learn about
|
|
Android, load as a project and run, or reuse in your own app. Note that multiple
|
|
samples packages are available — one for each Android platform version. When
|
|
you are choosing a samples package to download, select the one whose API Level
|
|
matches the API Level of the Android platform that you plan to use.</dd>

|
<p class="note"><strong>Tip:</strong> For easy access to the SDK tools from a command line, add the
|
|
location of the SDK's <code>tools/</code> and
|
|
<code>platform-tools</code> to your <code>PATH</code> environment variable.</p>
