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.
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.
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:
Important: 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.
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 Core App Quality 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.
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.

| Driver Attention | AU-MV |
App does not display on the Auto screen animated elements such as animated graphics, video, or progress bars. |

After submitting my app, how will I find out if my app does not meet all the requirements for Android Auto?
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 Google Play Developer Console account associated with the app.
Note: For information about how to publish your Auto app in Google Play, see Distributing to Android Auto.
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?
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.
Important: Due to this restriction, you should not use your production APK for Auto support prototyping.
