Otherwise, you can launch the Android SDK Manager in one of the following 15ways:</p> 16<ul> 17 <li>On Windows, double-click the <code>SDK Manager.exe</code> file at the root of the Android 18SDK directory.</li> 19 <li>On Mac or Linux, open a terminal and navigate to the <code>tools/</code> directory in the 20Android SDK, then execute <code>android sdk</code>.</li> 21</ul> 22</li> 23 24<li>The SDK Manager shows all the SDK packages available for you to add to your Android SDK. 25As a minimum configuration for your SDK, we recommend you install the following: 26<ul> 27 <li>The latest Tools packages (check the <strong>Tools</strong> folder).</li> 28 <li>The latest version of Android (check the first <strong>Android</strong> folder).</li> 29 <li>The Android Support Library (open the <strong>Extras</strong> folder and check 30 <strong>Android Support Library</strong>).</li> 31</ul> 32 33<p>Once you've chosen your packages, click <strong>Install</strong>. The Android SDK Manager 34installs the selected packages into your Android SDK environment.</li> 35</ol> 36 37<p>With these packages installed, you're ready to start developing. 38To get started, read <a href="{@docRoot}training/basics/firstapp/index.html" 39>Building Your First App</a>.</p> 40 41<img src="/images/sdk_manager_packages.png" alt="" height="396" /> 42<p class="img-caption"><strong>Figure 1.</strong> The Android SDK Manager shows the 43SDK packages that are available, already installed, or for which an update is available.</p> 44 45 46 47<h3>Additional information</h3> 48 49<ul> 50 <li>For more information about using the SDK Manager and some of the available packages, 51see the <a href="{@docRoot}tools/help/sdk-manager.html">SDK Manager</a> document.</li> 52 <li>This web site provides all information you need to develop Android apps, including <a 53href="{@docRoot}design/index.html">design guidelines</a>, 54<a href="{@docRoot}training/index.html">developer training</a>, <a 55href="{@docRoot}reference/packages.html">API reference</a>, and information 56about how you can <a href="{@docRoot}distribute/index.html">distribute your app</a>.
