This repository contains a React Native plugin that provides a Google Navigation component for building native Android and iOS apps using React.
Note
This package is in Beta until it reaches version 1.0. According to semantic versioning, breaking changes may be introduced before 1.0.
| Android | iOS | |
|---|---|---|
| Minimum mobile OS supported | SDK 23+ | iOS 15.0+ |
- A React Native project
- A Google Cloud project
- If you are a Mobility Services developer, you must contact Sales as described in Mobility services documentation.
- If you are not a Mobility Services developer, refer to Setup Google Cloud Project for instructions.
- An API key from the project above
- The API key must be configured for both Android and iOS. Refer to Android Using Api Keys and iOS Using Api Keys respectively for instructions.
- If targeting Android, Google Play Services installed and enabled
- Attributions and licensing text added to your app
Important
Apply API restrictions to the API key to limit usage to "Navigation SDK, "Maps SDK for Android", and "Maps SDK for iOS" for enhanced security and cost management. This helps guard against unauthorized use of your API key.
This package is listed on NPM as @googlemaps/react-native-navigation-sdk. Install it with:
npm i @googlemaps/react-native-navigation-sdkIn your TSX or JSX file, import the components you need:
import { NavigationView } from '@googlemaps/react-native-navigation-sdk';This package does not yet support new architecture. Make sure new architecture is disabled in your android/gradle.properties file:
newArchEnabled=falseTo ensure compatibility with AndroidX, enable Jetifier in your android/gradle.properties file:
# Automatically convert third-party libraries to use AndroidX
android.enableJetifier=trueThe minSdkVersion for your Android project must be set to 23 or higher in android/app/build.gradle:
android {
defaultConfig {
minSdkVersion 23
}
}If minSdkVersion is set to less than 34 (API 34), you need to configure desugaring for your Android app.
To enable desugaring, add the following configurations to android/app/build.gradle file:
android {
...
compileOptions {
coreLibraryDesugaringEnabled true
...
}
}
dependencies {
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs_nio:2.0.4'
}You may also need to upgrade to Gradle 8.4 and the Android Gradle plugin version 8.3.0
To securely store your API key, it is recommended to use the Google Maps Secrets Gradle Plugin. This plugin helps manage API keys without exposing them in your app's source code.
See example configuration for secrets plugin at example applications build.gradle file.
This package does not yet support new architecture. Make sure new architecture is disabled in your ios/Podfile:
ENV['RCT_NEW_ARCH_ENABLED'] = '0'To set up, specify your API key in the application delegate ios/Runner/AppDelegate.m:
#import <GoogleMaps/GoogleMaps.h>
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[GMSServices provideAPIKey:@"API_KEY"];
return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
Wrap application with the NavigationProvider component. This will provide the necessary context for navigation throughout your app.
import React from 'react';
import {
NavigationProvider,
TaskRemovedBehavior,
type TermsAndConditionsDialogOptions,
} from '@googlemaps/react-native-navigation-sdk';
const termsAndConditionsDialogOptions: TermsAndConditionsDialogOptions = {
title: 'Terms and Conditions Title',
companyName: 'Your Company Name',
showOnlyDisclaimer: true,
};
const App = () => {
return (
<NavigationProvider
termsAndConditionsDialogOptions={termsAndConditionsDialogOptions}
taskRemovedBehavior={TaskRemovedBehavior.CONTINUE_SERVICE}
>
{/* Add your application components here */}
</NavigationProvider>
);
};
export default App;The taskRemovedBehavior prop defines how the navigation should behave when a task is removed from the recent apps list on Android. It can either:
CONTINUE_SERVICE: Continue running in the background. (default)QUIT_SERVICE: Shut down immediately.
This prop has only an effect on Android.
You can use the useNavigation hook to access the NavigationController and control navigation within your components. The useNavigation hook also provides methods to add and remove listeners.
...
const { navigationController } = useNavigation();
const initializeNavigation = useCallback(async () => {
try {
await navigationController.init();
console.log('Navigation initialized');
} catch (error) {
console.error('Error initializing navigation', error);
}
}, [navigationController]);Note
Navigation can be controlled separately from the navigation views allowing navigation to be started and stopped independently.
To start navigation, set a destination and start guidance:
try {
const waypoint = {
title: 'Destination',
position: {
lat: 37.4220679,
lng: -122.0859545,
},
};
const routingOptions = {
travelMode: TravelMode.DRIVING,
avoidFerries: false,
avoidTolls: false,
};
const displayOptions: DisplayOptions = {
showDestinationMarkers: true,
showStopSigns: true,
showTrafficLights: true,
};
await navigationController.setDestinations([waypoint], routingOptions, displayOptions);
await navigationController.startGuidance();
} catch (error) {
console.error('Error starting navigation', error);
}const { navigationController, addListeners, removeListeners } = useNavigation();
const onArrival = useCallback((event: ArrivalEvent) => {
if (event.isFinalDestination) {
console.log('Final destination reached');
navigationController.stopGuidance();
} else {
console.log('Continuing to the next destination');
navigationController.continueToNextDestination();
navigationController.startGuidance();
}
}, [navigationController]);
const navigationCallbacks = useMemo(() => ({
onArrival,
// Add other callbacks here
}), [onArrival]);
useEffect(() => {
addListeners(navigationCallbacks);
return () => {
removeListeners(navigationCallbacks);
};
}, [navigationCallbacks, addListeners, removeListeners]);See NavigationCallbacks interface for a list of available callbacks.
When removing listeners, ensure you pass the same object that was used when adding them, as multiple listeners can be registered for the same event.
You can now add a NavigationView component to your application..
The view can be controlled with the ViewController (Navigation and MapView) that are retrieved from the onMapViewControllerCreated and onNavigationViewControllerCreated (respectively).
The NavigationView compoonent should be used within a View with a bounded size. Using it
in an unbounded widget will cause the application to behave unexpectedly.
// Permissions must have been granted by this point.
<NavigationView
androidStylingOptions={{
primaryDayModeThemeColor: '#34eba8',
headerDistanceValueTextColor: '#76b5c5',
headerInstructionsFirstRowTextSize: '20f',
}}
iOSStylingOptions={{
navigationHeaderPrimaryBackgroundColor: '#34eba8',
navigationHeaderDistanceValueTextColor: '#76b5c5',
}}
navigationViewCallbacks={navigationViewCallbacks}
mapViewCallbacks={mapViewCallbacks}
onMapViewControllerCreated={setMapViewController}
onNavigationViewControllerCreated={setNavigationViewController}
termsAndConditionsDialogOptions={termsAndConditionsDialogOptions}
/>You can also add a bare MapView that works as a normal map view without navigation functionality. MapView only need a MapViewController to be controlled.
<MapView
mapViewCallbacks={mapViewCallbacks}
onMapViewControllerCreated={setMapViewController}
/>The Google Navigation SDK React Native library offers functionalities that necessitate specific permissions from the mobile operating system. These include, but are not limited to, location services, background execution, and receiving background location updates.
Note
The management of these permissions falls outside the scope of the Navigation SDKs for Android and iOS. As a developer integrating these SDKs into your applications, you are responsible for requesting and obtaining the necessary permissions from the users of your app.
You can see example of handling permissions in the app.tsx file of the sample application:
import {request, PERMISSIONS, RESULTS} from 'react-native-permissions';
// ...
// Request permission for accessing the device's location.
const requestPermissions = async () => {
const result = await request(
Platform.OS === "android" ?
PERMISSIONS.ANDROID.ACCESS_COARSE_LOCATION :
PERMISSIONS.IOS.LOCATION_ALWAYS,
);
if (result === RESULTS.GRANTED) {
setArePermissionsApproved(true);
} else {
Snackbar.show({
text: 'Permissions are needed to proceed with the app. Please re-open and accept.',
duration: Snackbar.LENGTH_SHORT,
});
}
};By default, NavigationView uses all the available space provided to it. To adjust the size of the NavigationView, use the style prop.
<NavigationView
style={{width: 200, height: 50%}}
...
/>See the example directory for a complete navigation sample app.
This plugin is compatible with both Android Auto and Apple CarPlay infotainment systems. For more details, please refer to the respective platform documentation:
This package uses the Google Maps Navigation SDK for Android and iOS, which includes a dependency on the Google Maps SDK. If your project includes other React Native libraries with Google Maps SDK dependencies, you may encounter build errors due to version conflicts. To avoid this, it's recommended to avoid using multiple packages with Google Maps dependencies.
Note
This package provides a MapView component, which can be used as a classic Google Maps view without navigation. See Add a map view for details.
