<p>The Preview SDK is available from the Android SDK Manager.
This document assumes that you are familiar with Android app development, such
as using the Android SDK Manager and creating projects. If you are new to
Android, see <a href="{@docRoot}training/basics/firstapp/index.html">Building Your First
App</a> training lesson first.</a></p>

<h2 id="get-sdk">Get the Preview SDK</h2>

<p>To add the Android Preview SDK components to your development environment:</p>

<ol>
  <li>Start the <a href="{@docRoot}tools/help/sdk-manager.html">Android SDK Manager</a>.</li>
  <li>In the <strong>Tools</strong> section, select the latest Android <strong>SDK Tools</strong>,
    <strong>Platform-tools</strong>, and <strong>Build-tools</strong>.</li>
  <li>Select everything under the <strong>Android M Developer Preview</strong> section and
    click <strong>Install packages...</strong></li>
  <li>Accept the Licensing Agreement for all of the packages and click
    <strong>Install</strong>.</li>
</ol>

<p>After completing these steps, the preview components are available in your development
  environment. </p>


<h2 id="create-update">Create or Update a Project</h2>

<p>
  In order to use the preview APIs, you must create or update a development project to use
  the preview components.
</p>


<h3 id="create">Create a new project</h3>

<p>
  We recommend using Android Studio for create a project with the preview. Follow the steps
  described in <a href="{@docRoot}sdk/installing/create-project.html">Creating a Project</a>
  until you arrive at the <em>Form Factors</em> screen in the project wizard. Then perform
  the following steps to create a project configured for the preview.
</p>

<ul>
  <li>Check <strong>Phone and Tablet</strong>.</li>
  <li>Select <strong>API 22+: Android M (Preview)</strong> in <strong>Minimum SDK</strong>.</li>
</ul>


<h3 id="update">Update an existing project</h3>

<p>
  For existing projects, you must modify the project configuration to enable the preview APIs. In
  your the development environment, open the <code>build.gradle</code> file for your module and
  set these values as follows:
</p>

<ul>
  <li><code>compileSdkVersion</code> is set to <code>'android-MNC'</code></li>
  <li><code>minSdkVersion</code> is set to <code>'MNC'</code></li>
  <li><code>targetSdkVersion</code> is set to <code>'MNC'</code></li>
</ul>


<h2 id="setup-test">Set Up for Testing</h2>

<p>
  Testing app with the preview requires that you have a device or virtual device configured with
  the preview version of the platform. If you have a compatible device, you can install the preview
  platform for testing. Otherwise, you can configure a virtual device for testing.
</p>

<h3 id="setup-device">Set up a Physical Device</h3>

<p>
  If you have a Nexus 5, Nexus 6, Nexus 9, or Nexus Player, you can install a preview
  system image on these devices for testing your app.
  You can set up virtual device with the preview version of the platform from within Android Studio
  using the Android Virtual Device Manager tool.
</p>

<p class="caution">
  <strong>Important:</strong> Installing a preview image on a device <em>removes all data from
  it</em>, so you should backup any data before installing a preview image.
</p>

<h3 id="setupAVD">Set up a Virtual Device</h3>

<p>
  You can set up virtual device with the preview version of the platform from within Android Studio
  using the Android Virtual Device Manager tool.
</p>

<p>To create an AVD with the AVD Manager:</p>

<ol>
  <li>Install the M Preview SDK in your development environment, as described
      in <a href="{@docRoot}preview/setup-sdk.html">Setting Up the Preview
      SDK.</a></li>
  <li>Follow the steps in
      <a href="{@docRoot}tools/devices/managing-avds.html">Managing AVDs with AVD
      Manager</a>. Use the following settings:
    <ul>
      <li><strong>Device:</strong> Nexus 5, Nexus 6, Nexus 9, or Nexus Player</li>
      <li><strong>Target:</strong>
       Android M (Preview) - API Level M</li>
    </ul>
  </li>
</ol>
