<p>When designing support for Android Auto in your app, avoid driver distraction above all else.
  Apps that work with the Auto user interface should minimize distractions faced by the driver
  through best practices such as voice commands and very simple visual design.
</p>

<p>
  Great auto experiences are predictive and predictable. Apps that support Android Auto
  should show timely information to the driver only when it is relevant, and use
  simple, predictable patterns for common tasks.
</p>

<p>
  It's important that you test your auto app for the criteria listed on this page prior to
  submitting to Google Play for review. There are two ways to test your app:
</p>

<ol>
  <li> Use the Android Auto simulator to validate each checklist item. The simulator allows you to
  sideload your app for testing. For more information on the simulator, see
  <a href="{@docRoot}training/auto/start/index.html#test-it">Run and Test Auto Apps</a>.</li>
  <li>Test your app in a vehicle by uploading your app to the alpha/beta channel on Google Play.
  Apps will not work on Auto in vehicles unless they are installed from the Play Store.
  For more information, see <a
  href="{@docRoot}distribute/googleplay/developer-console.html#alpha-beta">Alpha and Beta Testing</a>.
  </li>
</ol>

<p class="caution">
  <strong>Important:</strong> The criteria listed in this page apply to your app's user interface
  and behavior when running on devices connected to an Android Auto screen. Apps must meet these
  criteria to qualify as an Android Auto app on Google Play.
</p>

<div class="headerLine">
  <h2 id="core">
  Core App Quality
  </h2>

<p>
 In addition to the Auto-specific criteria listed below, Auto apps should meet all relevant core app
 quality criteria for the Android platform, as detailed in the
  <a href="{@docRoot}distribute/essentials/quality/core.html">Core App Quality</a> criteria. Test
  your app against those criteria to ensure that they meet Android standards for navigation and
  design. Then test your app against all Auto-specific criteria, keeping in mind
  that, when running on a device connected to Android auto, your app must meet the requirements
  listed in this page.



<div class="headerLine">
  <h2 id="ux">
  Visual Design and User Interaction
  </h2>

</div>

<p>
  These criteria ensure that your app follows critical design and interaction patterns
  to ensure a consistent, intuitive, and enjoyable user experience on Android Auto. Many elements,
  such as the navigation drawer, card backgrounds, fonts and icon colors, are set and rendered by
  the system. Your own app-specific design elements must meet the following criteria.

  Frequently Asked Questions
  </h2>
</div>

<p style="margin-top:30px;">
  <strong>After submitting my app, how will I find out if my app does not meet all
    the requirements for Android Auto?</strong>
</p>
<p>
  If your app does not meet the usability requirements described on this page, the Play Store team
  will contact you through the email address specified in the <a href=
  "https://play.google.com/apps/publish/">Google Play Developer Console</a> account associated with
  the app.
</p>
<p class="note">
 <strong>Note:</strong> For information about how to publish your Auto app in Google Play, see <a
 href="{@docRoot}distribute/googleplay/auto.html">Distributing to Android Auto</a>.
</p>


<p style="margin-top:30px;">
  <strong>My app targets more than just Android Auto. If my app does not meet the Auto
  requirements, will my new or updated app still appear on Google Play for phones and
  tablets?</strong>
</p>
<p>
  No. When Google begins the approval process, your Auto app will undergo a driver safety
  review, and will not be
  available for distribution until the app is approved. Because this is the same APK as
  for phones and tablets, your Play Store updates for those devices will not be available until the
  Auto app approval process is complete.
</p>

<p class="caution">
  <strong>Important:</strong> Due to this restriction, you should not use your production APK
  for Auto support prototyping.
</p>
