<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>In Android Studio, click <strong>SDK Manager</strong>
<img src="{@docRoot}images/tools/sdk-manager-studio.png"
style="vertical-align:bottom;margin:0;height:17px" /> in the toolbar.</li>
  <li>If you're not using Android Studio:
    <ul>
      <li>Windows: Double-click the <code>SDK Manager.exe</code> file at the root of the Android
  SDK directory.</li>
      <li>Mac/Linux: Open a terminal and navigate to the <code>tools/</code> directory in the
      location where the Android SDK was installed, then execute <code>android sdk</code>.</li>
    </ul>
  </li>
</ul>

<p>When you open the SDK Manager for the first time, several packages are selected by
default. Leave these selected, but be sure you have everything you need
to get started by following these steps:</p>


<ol class="large">
<li>
  <h2 id="GetTools" class="norule">Get the latest SDK tools</h2>

<img src="/images/sdk_manager_packages.png" alt="" width="350" style="float:right;margin-left:20px" />

  <p>As a minimum when setting up the Android SDK,
  you should download the latest tools and Android platform:</p>
  <ol>
   <li>Open the Tools directory and select:
     <ul>
       <li><strong>Android SDK Tools</strong></li>
       <li><strong>Android SDK Platform-tools</strong></li>
       <li><strong>Android SDK Build-tools</strong> (highest version)</li>
     </ul>
   </li>
   <li>Open the first Android X.X folder (the latest version) and select:
     <ul>
      <li><strong>SDK Platform</strong></li>
      <li>A system image for the emulator, such as <br>
      <strong>ARM EABI v7a System Image</strong></li>
     </ul>
   </li>
  </ol>
</li>

<li>
  <h2 id="GetSupportLib" class="norule">Get the support library for additional APIs</h2>

  <div class="sidebox">
    <p>The support library is required for:</p>
    <ul>
      <li><a href="{@docRoot}wear/index.html">Android Wear</a></li>
      <li><a href="{@docRoot}tv/index.html">Android TV</a></li>
      <li><a href="{@docRoot}google/play-services/cast.html">Google Cast</a></li>
    </ul>

    <p>It also provides these popular APIs:</p>
    <ul>
      <li><a href="{@docRoot}reference/android/support/v4/widget/DrawerLayout.html">Navigation
      drawer</a></li>
      <li><a href="{@docRoot}reference/android/support/v4/view/ViewPager.html">Swipe views</a></li>
      <li><a href="{@docRoot}reference/android/support/v7/app/ActionBar.html">Backward-compatible
      action bar</a></li>
    </ul>
  </div>

  <p>The <a href="{@docRoot}tools/support-library/features.html">Android Support Library</a>
  provides an extended set of APIs that are compatible with most versions of Android.</p>

  <p>Open the <strong>Extras</strong> directory and select:</p>
     <ul>
       <li><strong>Android Support Repository</strong></li>
       <li><strong>Android Support Library</strong></li>
     </ul>

  <p>&nbsp;</p>
  <p>&nbsp;</p>

</li>


<li>
  <h2 id="GetGoogle" class="norule">Get Google Play services for even more APIs</h2>

  <div class="sidebox">

    <p>The Google Play services APIs provide a variety of features and services for your Android
    apps, such as:</p>
    <ul>
      <li><a href="{@docRoot}google/play-services/plus.html">User authentication</a></li>
      <li><a href="{@docRoot}google/play-services/maps.html">Google Maps</a></li>
      <li><a href="{@docRoot}google/play-services/cast.html">Google Cast</a></li>
      <li><a href="{@docRoot}google/play-services/games.html">Games achievements and
      leaderboards</a></li>
      <li><a href="{@docRoot}google/play-services/index.html">And much more</a></li>
    </ul>
  </div>

  <p>To develop with Google APIs, you need the Google Play services package:</p>
  <p>Open the <strong>Extras</strong> directory and select:</p>
     <ul>
       <li><strong>Google Repository</strong></li>
       <li><strong>Google Play services</strong></li>
     </ul>

  <p class="note"><strong>Note:</strong> Google Play services APIs are not available on all
  Android-powered devices, but are available on all devices with Google Play Store. To use these
  APIs in the Android emulator, you must also install the the <strong>Google APIs</strong>
  system image from the latest Android X.X directory in the SDK Manager.</p>
</li>


<li>
  <h2 id="Install" class="norule">Install the packages</h2>
  <p>Once you've selected all the desired packages, continue to install:</p>
  <ol>
   <li>Click <strong>Install X packages</strong>.</li>
   <li>In the next window, double-click each package name on the left
   to accept the license agreement for each.</li>
   <li>Click <strong>Install</strong>.</li>
  </ol>
  <p>The download progress is shown at the bottom of the SDK Manager window.
  <strong>Do not exit the SDK Manager</strong> or it will cancel the download.</p>
</li>

<li>
  <h2 id="Build" class="norule">Build something!</h2>

<p>With the above packages now in your Android SDK, you're ready to build apps
for Android. As new tools and other APIs become available, simply launch the SDK Manager
  to download the new packages for your SDK.</p>

<p>Here are a few options for how you should proceed:</p>
