React Native Auto Play

React Native Auto Play provides a comprehensive solution for integrating your React Native application with both Apple CarPlay and Android Auto. This library allows you to build automotive-specific user interfaces using familiar React Native components and concepts.

Features

• Cross-Platform: Write once, run on both Apple CarPlay and Android Auto.
• Both Architectures: Supports both the legacy and the new React Native architecture.
• Template-Based UI: Utilize a rich set of templates like MapTemplate, ListTemplate, GridTemplate, and more to build UIs that comply with automotive design guidelines.
• Navigation APIs: Build full-featured navigation experiences with APIs for trip management, maneuvers, and route guidance.
• Dashboard & Cluster Support: Extend your app's presence to the CarPlay Dashboard (CarPlay only) and instrument cluster displays (CarPlay & Android Auto).
• Hooks-Based API: A modern and intuitive API using React Hooks (useMapTemplate, useVoiceInput, etc.) for interacting with the automotive system.
• Headless Operation: Runs in the background to keep the automotive experience alive even when the main app is not in the foreground.
• Powered by NitroModules

Installation

1. Install the package and its peer dependencies:

   yarn add @iternio/react-native-auto-play react-native-nitro-modules

2. For iOS, install the pods:

   cd ios && pod install && cd ..

3. For Android, the library will be autolinked.

Platform Setup

iOS

Bundle identifier

To get the CarPlay app showing up you need to set a proper Bundle Identifier:

• Open example.xcodeproj
• Select the example target, go to the Signing & Capabilities tab.
• Under Signing > Bundle Identifier, enter your unique bundle ID (e.g., at.g4rb4g3.autoplay.example).

Entitlements

Create a Entitlements.plist file in your project, paste the content below and adjust the com.apple.developer.carplay-maps key to your needs. Check Apple docs for details.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>com.apple.developer.carplay-maps</key>
        <true/>
        <key>application-identifier</key>
        <string>$(AppIdentifierPrefix)$(CFBundleIdentifier)</string>
    </dict>
</plist>

• Open example.xcodeproj
• Select the example target, go to the Build Settings tab and filter for entitlement.
• On Code Signing Entitlements enter the path to the Entitlements.plist file you just created.

Scene delegates

Depending on your needs you need to set up the scene delegates. The library brings following delegates:

• WindowApplicationSceneDelegate - The main scene visible on your mobile device
• HeadUnitSceneDelegate - The main scene on CarPlay device
• DashboardSceneDelegate - Scene visible on the CarPlay overview screen usualy with some other widgets like calendar, weather or music.
• ClusterSceneDelegate - Scene visible on a cars instrument cluster.

Paste this into your Info.plist and adjust it to your needs. Check Apple docs for details.

MapTemplate

if you want to make use of the MapTemplate and render react components you need to add this to your AppDelegate.swift This should cover old and new architecture, adjust to your needs!

@objc func getRootViewForAutoplay(
    moduleName: String,
    initialProperties: [String: Any]?
  ) -> UIView? {
    if RCTIsNewArchEnabled() {
      if let factory = reactNativeFactory?.rootViewFactory as? ExpoReactRootViewFactory {
         return factory.superView(
          withModuleName: moduleName,
          initialProperties: initialProperties,
          launchOptions: nil
        )
      }
      
      return reactNativeFactory?.rootViewFactory.view(
        withModuleName: moduleName,
        initialProperties: initialProperties
      )
    }

    if let rootView = window?.rootViewController?.view as? RCTRootView {
      return RCTRootView(
        bridge: rootView.bridge,
        moduleName: moduleName,
        initialProperties: initialProperties
      )
    }

    return nil
  }

MapTemplate maneuver dark & light mode

It is recommended to attach a listener to MapTemplate.onAppearanceDidChange and send maneuver updates based on this to make sure the colors are applied properly. Reason for this is that CarPlay does not allow for color updates on maneuvers shown on the screen. You need to send maneuvers with a new id to get them updated properly on the screen. The color properties do not need to handle the mode change, best practice is to use ThemedColor whenever possible and set appropriate light and dark mode colors. This is mainly required on CarPlay for now since Android Auto lacks light mode.

Dashboard buttons

In case you wanna open up your CarPlay app from one of the CarPlay dashboard buttons set launchHeadUnitScene on the button and add this to your Info.plist. Make sure to apply your "Bundle Identifier" instead of the example one.

<key>CFBundleURLTypes</key>
<array>
	<dict>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
		<key>CFBundleURLSchemes</key>
		<array>
			<string>at.g4rb4g3.autoplay.example</string>
		</array>
	</dict>
</array>

Android Auto

No platform specific setup required - we got you covered with all the required stuff.

Android Auto Customization

You can customize certain behaviors of the library on Android Auto by setting properties in your app's android/gradle.properties file.

• Telemetry Update Interval: Control how often telemetry data is updated.

  ReactNativeAutoPlay_androidTelemetryUpdateInterval=4000

  The value is in milliseconds. The default is 4000.

• UI Scale Factor: Apply a scaling factor to the React Native UI rendered on the car screen. This does not affect the templates.

  ReactNativeAutoPlay_androidAutoScaleFactor=1.5f

  The default value is 1.5.

• Cluster Splash Screen: Customize the splash screen shown on the instrument cluster.

  # Delay in milliseconds after the root component is rendered before the splash screen hides.
  ReactNativeAutoPlay_clusterSplashDelayMs=1000
  # Duration of the splash screen fade out animation in milliseconds.
  ReactNativeAutoPlay_clusterSplashDurationMs=500

  The default values are 1000 for the delay and 500 for the duration.

Icons

The library is using Material Symbols for iconography. The font is bundled with the library, so no extra setup is required. You can use these icons on both Android Auto and CarPlay.

It is also possible to use custom bundled images (e.g. PNG, WEBP or Vector Drawables). Make sure to add them to your native projects.

• iOS: Add to your Images.xcassets
• Android: Add to res/drawable

Usage

1. Register the AutoPlay Components

You need to register your AutoPlay components in your app's entry file (e.g., index.js). This includes setting up the headless task that runs when CarPlay or Android Auto is connected.

// index.js
import { AppRegistry } from 'react-native';
import { name as appName } from './app.json';
import App from './src/App';
import registerAutoPlay from './src/AutoPlay'; // Your AutoPlay setup

AppRegistry.registerComponent(appName, () => App);
registerAutoPlay();

2. Create the AutoPlay Experience

Create a file (e.g., src/AutoPlay.js) to define your automotive UI. This is where you will configure your templates and the React components they will render.

// src/AutoPlay.tsx
import {
  AutoPlayCluster,
  CarPlayDashboard,
  HybridAutoPlay,
  MapTemplate,
  useMapTemplate,
} from '@iternio/react-native-auto-play';
import React, { useEffect } from 'react';
import { Platform, Text, View } from 'react-native';

// A simple component that can be reused across different screens
const MyCarScreen = ({ title }: { title: string }) => (
  <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
    <Text style={{ color: 'white', fontSize: 24 }}>{title}</Text>
  </View>
);

// The React component to be rendered inside the MapTemplate
const MapScreen = () => {
  const mapTemplate = useMapTemplate();

  useEffect(() => {
    // Show an alert on the car screen when the component mounts
    mapTemplate?.showAlert({
      id: 'welcome-alert',
      title: { text: 'Welcome!' },
      subtitle: { text: 'Your app is now running on the car screen.' },
      durationMs: 5000,
      priority: 'low',
    });
  }, [mapTemplate]);

  return <MyCarScreen title="Hello, Map!" />;
};

const registerAutoPlay = () => {
  const onConnect = () => {
    // When a car is connected, create a MapTemplate and set it as the root
    const rootTemplate = new MapTemplate({
      component: MapScreen, // Render our map component
      headerActions: {
        android: [
          {
            type: 'image',
            image: { name: 'search', type: 'glyph' },
            onPress: () => console.log('Search pressed'),
          },
          {
            type: 'image',
            image: { name: 'cog', type: 'glyph' },
            onPress: () => console.log('Settings pressed'),
          },
        ],
        ios: {
          leadingNavigationBarButtons: [
            {
              type: 'image',
              image: { name: 'search', type: 'glyph' },
              onPress: () => console.log('Search pressed'),
            },
          ],
          trailingNavigationBarButtons: [
            {
              type: 'image',
              image: { name: 'cog', type: 'glyph' },
              onPress: () => console.log('Settings pressed'),
            },
          ],
        },
      },
    });

    rootTemplate.setRootTemplate();
  };

  // Register components for the Dashboard and Cluster
  if (Platform.OS === 'ios') {
    CarPlayDashboard.setComponent(() => <MyCarScreen title="Hello, Dashboard!" />);
  }
  AutoPlayCluster.setComponent(() => <MyCarScreen title="Hello, Cluster!" />);


  // Add listeners for car connection and disconnection events
  HybridAutoPlay.addListener('didConnect', onConnect);
  HybridAutoPlay.addListener('didDisconnect', () => {
    console.log('Car disconnected');
  });
};
export default registerAutoPlay;

API Reference

Main Object

• HybridAutoPlay: The primary interface for interacting with the native module, handling connection status and events.

Core Types

AutoText

Most text props accept AutoText so you can localize and provide variants. You can pass either a string or an object with text/variants as used throughout the example app.

AutoImage

Images are provided as AutoImage objects with a type and name. The built-in icon set is Material Symbols (see Icons). You can also use bundled images from your native project.

RootComponentInitialProps

All root components rendered by templates/scenes receive RootComponentInitialProps:

• id: Module identifier (e.g. AutoPlayRoot, CarPlayDashboard, or a cluster UUID).
• rootTag: React Native root tag.
• colorScheme: 'light' | 'dark' initial color scheme (listen to onAppearanceDidChange on MapTemplate for updates).
• window: { width, height, scale }.

Header Actions (Important)

On Android, header actions may be omitted, although this is not recommended. If headerActions is undefined, the system automatically renders the app icon in the header. Because Android Auto enforces monochrome icons, this can result in a poor-looking button.

Use these rules to avoid crashes:

1. For List/Grid/Information/Search/Message templates on Android, always pass the structured object format (alignment is implicit via startHeaderAction/endHeaderActions):

const headerActions: HeaderActions<MyTemplate> = {
  android: {
    startHeaderAction: { type: 'back', onPress: (t) => HybridAutoPlay.popTemplate() },
    endHeaderActions: [
      { type: 'image', image: { name: 'help', type: 'glyph' }, onPress: () => {} },
    ],
  },
  ios: {
    backButton: { type: 'back', onPress: (t) => HybridAutoPlay.popTemplate() },
    trailingNavigationBarButtons: [
      { type: 'image', image: { name: 'close', type: 'glyph' }, onPress: () => {} },
    ],
  },
};

⚠️ Do not pass a raw array of actions to headerActions on Android for these templates. Arrays are only valid for MapTemplate header actions (see below). Passing an array for header-based templates results in actions without alignment and can crash on Android.

2. For MapTemplate on Android, you can use the array format (1–4 actions) for the action strip:

const mapHeaderActions: MapTemplateConfig['headerActions'] = {
  android: [
    { type: 'image', image: { name: 'list', type: 'glyph' }, onPress: () => {} },
    { type: 'image', image: { name: 'search', type: 'glyph' }, onPress: () => {} },
  ],
  ios: {
    leadingNavigationBarButtons: [
      { type: 'image', image: { name: 'list', type: 'glyph' }, onPress: () => {} },
    ],
  },
};

Header action shapes (structured overview):

| Platform | Property | Shape | Limits / Notes | | --- | --- | --- | --- | | Android (header templates) | headerActions.android | { startHeaderAction?, endHeaderActions? } | endHeaderActions: 1–2 buttons. startHeaderAction can be appIcon/back/custom. | | Android (MapTemplate) | headerActions.android | ActionButton[] | 1–4 action strip buttons. | | iOS | headerActions.ios | { backButton?, leadingNavigationBarButtons?, trailingNavigationBarButtons? } | Each list supports 1–2 buttons. backButton optional (system back is added if omitted). |

Actions & Button Types (Quick Reference)

• Android header actions use startHeaderAction + endHeaderActions:
  • startHeaderAction: AppButton | BackButton | ActionButton
  • endHeaderActions: 1–2 buttons
  • If headerActions is omitted: Android renders the app icon automatically.
• iOS header actions use:
  • backButton (optional, otherwise iOS provides a default back action)
  • leadingNavigationBarButtons (1–2)
  • trailingNavigationBarButtons (1–2)
• MapTemplate map buttons: 1–4 buttons, including the special pan button.

Event & Listener APIs

This section lists the available listeners and lifecycle callbacks so you can wire up connection state, visibility, cluster settings, and system events.

HybridAutoPlay listeners

| API | Payload | Notes | | --- | --- | --- | | HybridAutoPlay.addListener(event, cb) | event: 'didConnect' 'didDisconnect' | Connection changes for the head unit. | | HybridAutoPlay.addListenerRenderState(moduleName, cb) | cb(visibility: 'willAppear' \| 'didAppear' \| 'willDisappear' \| 'didDisappear') | Use AutoPlayModules.* or a cluster UUID. | | HybridAutoPlay.addListenerVoiceInput(cb) | cb(location?, query?) | Android-only voice input. | | HybridAutoPlay.addSafeAreaInsetsListener(moduleName, cb) | cb(insets) | Safe area inset changes for any module. |

import { AutoPlayModules, HybridAutoPlay } from '@iternio/react-native-auto-play';

const cleanup = HybridAutoPlay.addListener('didConnect', () => {
  console.log('Head unit connected');
});

const removeVisibility = HybridAutoPlay.addListenerRenderState(
  AutoPlayModules.AutoPlayRoot,
  (state) => console.log('AutoPlayRoot state', state)
);

Template lifecycle callbacks

All templates accept these lifecycle callbacks in their config:

• onWillAppear(animated?)
• onDidAppear(animated?)
• onWillDisappear(animated?)
• onDidDisappear(animated?)
• onPopped() (not supported on all iOS templates, see notes in code)

const template = new ListTemplate({
  title: { text: 'Menu' },
  onWillAppear: () => console.log('will appear'),
  onPopped: () => console.log('popped forever'),
});

MapTemplate callbacks

Map-specific callbacks live on MapTemplateConfig:

• onDidPan({ x, y })
• onDidUpdateZoomGestureWithCenter({ x, y }, scale)
• onClick({ x, y }) (Android)
• onDoubleClick({ x, y }) (Android)
• onAppearanceDidChange(colorScheme)
• onAutoDriveEnabled(template) (Android)
• onStopNavigation(template) (required)

AutoPlayCluster listeners (instrument cluster)

| API | Payload | Notes | | --- | --- | --- | | AutoPlayCluster.addListenerColorScheme(cb) | (clusterId, colorScheme) | iOS + Android. | | AutoPlayCluster.addListenerZoom(cb) | (clusterId, zoomEvent) | iOS only. | | AutoPlayCluster.addListenerCompass(cb) | (clusterId, enabled) | iOS only. | | AutoPlayCluster.addListenerSpeedLimit(cb) | (clusterId, enabled) | iOS only. |

const removeCompass = AutoPlayCluster.addListenerCompass((clusterId, enabled) => {
  console.log('Cluster', clusterId, 'compass', enabled);
});

CarPlayDashboard listeners (iOS)

| API | Payload | Notes | | --- | --- | --- | | CarPlayDashboard.addListener(event, cb) | event: 'didConnect' 'didDisconnect' | Connection changes for the dashboard scene. | | CarPlayDashboard.addListenerRenderState(cb) | cb(visibility) | Scene visibility changes. | | CarPlayDashboard.addListenerColorScheme(cb) | cb(colorScheme) | Light/dark changes. |

Localization

The library allows you to pass distances and durations and formats them according to the system defaults. For iOS make sure to provide all supported app languages in Info.plist CFBundleLocalizations for this to work properly, missing languages will use CFBundleDevelopmentRegion as fallback which is en most of the time. This results in a mix up with the region which might result in en_AT instead of de_AT for example.

Component Props

RootComponentInitialProps

Every component registered with a template (e.g., via MapTemplate's component prop) or a scene (e.g., CarPlayDashboard.setComponent) receives RootComponentInitialProps as its props. This object contains important information about the environment where the component is being rendered.

• id: A unique identifier for the screen. Can be AutoPlayRoot for the main screen, CarPlayDashboard for the dashboard, or a UUID for cluster displays.
• rootTag: The React Native root tag for the view.
• colorScheme: The initial color scheme ('dark' or 'light'). Listen for changes with the onAppearanceDidChange event on the template.
• window: An object containing the dimensions and scale of the screen:
  • width: The width of the screen.
  • height: The height of the screen.
  • scale: The screen's scale factor.

iOS Specific Properties:

On iOS, the component registered with AutoPlayCluster.setComponent receives additional props in its RootComponentInitialProps that indicate user preferences for the cluster display. You can also listen for changes to these settings.

• compass: boolean: Indicates if the compass display is enabled by the user. The initial value is passed as a prop.
• speedLimit: boolean: Indicates if the speed limit display is enabled by the user. The initial value is passed as a prop.

You can listen for changes to these settings using listeners on the AutoPlayCluster object:

// Listen for compass setting changes
const compassCleanup = AutoPlayCluster.addListenerCompass((clusterId, isEnabled) => {
  console.log(`Compass is now ${isEnabled ? 'enabled' : 'disabled'} for cluster ${clusterId}`);
});

// Listen for speed limit setting changes
const speedLimitCleanup = AutoPlayCluster.addListenerSpeedLimit((clusterId, isEnabled) => {
  console.log(`Speed limit is now ${isEnabled ? 'enabled' : 'disabled'} for cluster ${clusterId}`);
});

// Don't forget to clean up the listeners when your component unmounts
useEffect(() => {
  return () => {
    compassCleanup();
    speedLimitCleanup();
  };
}, []);

Templates

| Template | Purpose | Notes | | --- | --- | --- | | MapTemplate | Navigation, map rendering | Use as root; supports map buttons & navigation APIs. | | ListTemplate | Lists/menus | Supports sections, radio/toggle rows. | | GridTemplate | Action grid | Use GridButton items. | | SearchTemplate | Search UI | Android-only search bar callbacks. | | InformationTemplate | Info panels | Android uses PaneTemplate; iOS uses InformationTemplate. | | MessageTemplate | Modal messages | Always shown on top until popped. |

Template quick examples:

// MapTemplate
const map = new MapTemplate({
  component: MapScreen,
  onStopNavigation: () => {},
  headerActions: { android: [{ type: 'image', image: { name: 'list', type: 'glyph' }, onPress: () => {} }] },
});
map.setRootTemplate();

// ListTemplate
new ListTemplate({
  title: { text: 'Destinations' },
  sections: [{ type: 'default', title: 'Recent', items: [{ type: 'default', title: { text: 'Home' }, onPress: () => {} }] }],
  headerActions: { android: { startHeaderAction: { type: 'back', onPress: () => {} } } },
}).push();

Hooks

• useMapTemplate(): Get a reference to the parent MapTemplate instance.
• useVoiceInput(): Access voice input functionality - Android Auto only.
• useSafeAreaInsets(): Get safe area insets for any root component.
• useFocusedEffect(): A useEffect alternative that executes when the specified component is visible to the user - use any of the AutoPlayModules enum or a cluster uuid to sepcify the component the effect should listen for.
• useAndroidAutoTelemetry(): Access to car telemetry data on Android Auto.

  import {
    useAndroidAutoTelemetry,
    AndroidAutoTelemetryPermissions,
  } from '@iternio/react-native-auto-play';
  
  const MyComponent = () => {
    const { telemetry, permissionsGranted, error } = useAndroidAutoTelemetry({
      requiredPermissions: [
        AndroidAutoTelemetryPermissions.Speed,
        AndroidAutoTelemetryPermissions.Energy,
        AndroidAutoTelemetryPermissions.Odometer,
      ],
    });
  
    if (!permissionsGranted) {
      return <Text>Waiting for telemetry permissions...</Text>;
    }
  
    if (error) {
      return <Text>Error getting telemetry: {error}</Text>;
    }
  
    return (
      <View>
        <Text>Speed: {telemetry?.speed?.value} km/h</Text>
        <Text>Fuel Level: {telemetry?.fuelLevel?.value}%</Text>
        <Text>Battery Level: {telemetry?.batteryLevel?.value}%</Text>
        <Text>Range: {telemetry?.range?.value} km</Text>
        <Text>Odometer: {telemetry?.odometer?.value} km</Text>
      </View>
    );
  }

  The telemetry object may contain the following fields. Each field is an object with a value and a timestamp.
  • speed: Speed in km/h.
  • fuelLevel: Fuel level in %.
  • batteryLevel: Battery level in %.
  • range: Range in km.
  • odometer: Odometer in km.
  • vehicle: Vehicle information (model name, model year, manufacturer).

Scenes

• CarPlayDashboard: A component to render content on the CarPlay dashboard (CarPlay only).
• AutoPlayCluster: A component to render content on the instrument cluster (CarPlay & Android Auto).

Scene APIs (overview):

CarPlayDashboard (iOS)

• setComponent(component) — register the React component (call once).
• setButtons(buttons) — required to make the dashboard visible.
• addListener(event, cb) — didConnect / didDisconnect.
• addListenerRenderState(cb) — scene visibility callbacks.
• addListenerColorScheme(cb) — light/dark changes.

CarPlayDashboard.setButtons([
  {
    titleVariants: ['Open App'],

AutoPlayCluster

• setComponent(component) — register the cluster component.
• setAttributedInactiveDescriptionVariants(variants) — iOS only inactive text.
• addListenerColorScheme(cb) / addListenerZoom(cb) / addListenerCompass(cb) / addListenerSpeedLimit(cb).

Known Issues

iOS

• Broken exceptions with react-native-skia: When using react-native-skia up to version 2.4.7, exceptions on iOS are not reported correctly. This is fixed in newer versions of react-native-skia. For more details, see this pull request.
• AppState on iOS: The AppState module from React Native does not work correctly on iOS because this library uses scenes, which are not supported by the stock AppState module. This library provides a custom state listener that works for both Android and iOS. Use HybridAutoPlay.addListenerRenderState instead of AppState.
• Timers stop on screen lock: iOS stops all timers when the device's main screen is turned off. To ensure timers continue to run (which is often necessary for background tasks related to autoplay), a patch for react-native is required. A patch is included in the root patches/ directory and can be applied using patch-package.
• expo-splash-screen stuck on iOS: The expo-splash-screen module is broken on iOS because it does not support scenes, which are used by this library. This can cause the splash screen to be stuck on either the mobile device or on CarPlay. To fix this, a patch for expo-splash-screen is included in the root patches/ directory and can be applied using patch-package. After applying the patch, you can hide the splash screen for a specific scene by passing the module name to the hide or hideAsync function. The module name can be one of the values from the AutoPlayModules enum or the UUID of a cluster screen.

  import { hideAsync } from 'expo-splash-screen';
  import { AutoPlayModules } from '@iternio/react-native-auto-play';
  
  // Hide the splash screen for the main app
  hideAsync(AutoPlayModules.App);
  
  // Hide the splash screen for the CarPlay screen
  hideAsync(AutoPlayModules.AutoPlayRoot);
