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-as13">Get Android Studio 1.3</h2> <p>The Developer Preview is best used with Android Studio 1.3, which is in preview status. It is highly recommended that you install the preview version of Android Studio 1.3 to work with the Preview SDK.</p> <p class="caution"><strong>Caution:</strong> The canary preview of Android Studio 1.3 is still in active development. If you are using your primary development machine to test the developer preview, you can create a second installation of Android Studio to use for testing.</p> <p>To install the Android Studio 1.3 preview:</p> <ol> <li>Download and launch <a href="{@docRoot}tools/studio/index.html">Android Studio</a>. </li> <li>Open the <strong>Settings</strong> window (on Windows, you can do this by choosing <strong>File > Settings</strong>). Choose the <strong>Appearance & Behavior > System Settings > Updates</strong> panel. <p class="aside">On OSX, you can find the <strong>Appearance & Behavior</strong> panel in Android Studio's <strong>Preferences</strong> window.</p> </li> <li> On the <strong>Updates</strong> panel, choose the option <strong>Automatically check updates for: Canary Channel</strong>. </li> <li>On the <strong>Updates</strong> panel, select <strong>Check Now</strong> to check for the latest canary build. Download and install the build when you are prompted. </li> </ol> <h2 id="get-sdk">Get the Preview SDK</h2> <p>To add the Preview SDK components to your development environment:</p> <ol> <li>Launch the Android Studio 1.3 preview. </li> <li>Open the <strong>Settings</strong> window (on Windows, you can do this by choosing <strong>File > Settings</strong>). Choose the <strong>Appearance & Behavior > System Settings > Updates</strong> panel. <p class="aside">On OSX, you can find the <strong>Appearance & Behavior</strong> panel in Android Studio's <strong>Preferences</strong> window.</p> </li> <li>On the <strong>Updates</strong> panel, choose the options <strong>Automatically check updates for: Canary Channel</strong> and <strong>Automatically check updates for Android SDK: Preview Channel</strong>. </li> <li>Launch the <strong>Android SDK Manager</strong>. (With Android Studio 1.3, the SDK Manager is integrated into Android Studio instead of being a standalone application.) </li> <li>Under the <strong>Platforms</strong> section, select <strong>Android MNC Preview</strong>. </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>Click <strong>Install packages</strong> and accept the licensing agreement for all of the packages. </li> <li>Verify that the M Developer Preview is installed by opening the <strong> Settings</strong> window and choosing the <strong>Appearance & Behavior > System Settings > Android SDK</strong> panel.</li> <li>On the <strong>Android SDK</strong> panel, choose the <strong>SDK Platforms</strong> tab. <strong>Android MNC Preview</strong> should be listed as <em>Installed</em>. Also, open the <strong>SDK Tools</strong> tab to verify that the latest tools are installed. </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 to 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>MNC: 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 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 an 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 Android TV, you can install a preview system image on these devices for testing your app. You can set up a 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 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 Android TV</li> <li><strong>Target:</strong> Android M (Preview) - API Level M</li> <li><strong>ABI:</strong> x86</li> </ul> </li> </ol> <p> For more information about creating virtual devices for testing, see <a href= "{@docRoot}tools/devices/index.html">Managing Virtual Devices</a>. </p>
