Auto app quality

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's 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 before submitting to Google Play for review. There are two ways to test your app:

  1. Use the Android Auto Desktop Head Unit (DHU) to validate each checklist item. The DHU allows you to sideload your app for testing. For more information on the DHU, see Run and Test Auto Apps.
  2. 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 Alpha and Beta Testing.

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 these guidelines, you should also read the Android Auto UX guidelines for audio apps and messaging apps if those apply to you.

Core app quality

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 core app quality. Test your app against those criteria to ensure that it meets Android standards for navigation and design. Then test your app against all Auto-specific criteria, remembering that, when running on a device connected to Android Auto, your app must meet the requirements listed on this page.

Visual design and user interaction

These criteria ensure that your app follows critical design and interaction patterns to offer 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 app-specific design elements must meet the following criteria when running on a device connected to Android Auto.

Type Test Description
Driver Attention AU-MV

The app does not display animated elements on the Auto screen such as animated graphics, video, or progress bars.

AU-VA

The app does not display text-based advertising other than the advertiser's name or the product name.

AU-IM

App elements do not display any images on the Auto screen. Exceptions include: apps may display a single static image for content context in the background of the consumption screen, such as album art or the advertiser's corporate logo. Apps may also display icons in the content navigation drawer.

AU-DS

The app does not include games or other features outside the app types intended for Auto. (Learn How)

AU-VI

While the app is interacting with the car screen, the app does not activate the phone screen to present any form of visual information (notifications, toasts, video, images, advertising, or similar).

AU-AB

App-specific buttons respond to user actions with no more than a two-second delay.

Functionality

These criteria ensure that your app is configured correctly and provides the expected functional behavior when running on a device connected to Android Auto.

General AU-LT

The app launches in no more than 10 seconds.

AU-LC

The app loads content in no more than 10 seconds.

AU-FP

Auto app functionality works as expected or described in the app's Google Play Store listing.

AU-RL

When the app is relaunched from the home screen, the app restores the app state as closely as possible to the previous state.

Frequently asked questions

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 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 other devices?

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 other devices, 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.
