Installation

1. Install the package

npm i -S react-native-map-link         # or yarn add react-native-map-link

2. Post-install steps

Based on the platforms your app supports, you also need to:

iOS – Update Info.plist

To allow your app to detect if any of the directions apps are installed, an extra step is required on iOS. Your app needs to provide the LSApplicationQueriesSchemes key inside ios/{my-project}/Info.plist to specify the URL schemes with which the app can interact.

Just add this in your Info.plist depending on which apps you'd like to support. Omitting these might mean that the library can't detect some of the maps apps installed by the user.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>comgooglemaps</string>
    <string>citymapper</string>
    <string>uber</string>
    <string>lyft</string>
    <string>transit</string>
    <string>truckmap</string>
    <string>waze</string>
    <string>yandexnavi</string>
    <string>moovit</string>
    <string>yandextaxi</string>
    <string>yandexmaps</string>
    <string>kakaomap</string>
    <string>szn-mapy</string>
    <string>mapsme</string>
    <string>osmandmaps</string>

    <string>nmap</string>
    <string>dgis</string>
    <string>lftgpas</string>
</array>

Android – Update AndroidManifest.xml

When switching to Android 11/Android SDK 30 (i.e. using Expo SDK 41), this library doesn't work out of the box anymore. The reason is the new Package Visibilty security feature. We'll have to update our AndroidManifest.xml to explicitly allow querying for other apps.

You can do so by coping the <queries> statement below, and pasting it in the top level of your AndroidManifest (i.e. within the <manifest> ... </manifest>).

<queries>
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="http"/>
  </intent>
  <intent>
    <action android:name="android.intent.action.VIEW" />

If you're running into a 'unexpected element <queries> found in <manifest>' error, make sure you have an updated version of Gradle in your android/build.gradle file:

classpath("com.android.tools.build:gradle:3.5.4")

Usage

Using the showLocation function will shown an action sheet on iOS and an alert on Android, without any custom styling:

import {showLocation} from 'react-native-map-link';

showLocation({
  latitude: 38.8976763,
  longitude: -77.0387185,
  sourceLatitude: -8.0870631, // optionally specify starting location for directions
  sourceLongitude: -34.8941619, // not optional if sourceLatitude is specified
  title: 'The White House', // optional
  googleForceLatLon: false, // optionally force GoogleMaps to use the latlon for the query instead of the title
  googlePlaceId: 'ChIJGVtI4by3t4kRr51d_Qm_x58', // optionally specify the google-place-id
  alwaysIncludeGoogle: true, // optional, true will always add Google Maps to iOS and open in Safari, even if app is not installed (default: false)
  dialogTitle: 'This is the dialog Title', // optional (default: 'Open in Maps')
  dialogMessage: 'This is the amazing dialog Message', // optional (default: 'What app would you like to use?')
  cancelText: 'This is the cancel button text', // optional (default: 'Cancel')
  appsWhiteList: ['google-maps'], // optionally you can set which apps to show (default: will show all supported apps installed on device)
  naverCallerName: 'com.example.myapp', // to link into Naver Map You should provide your appname which is the bundle ID in iOS and applicationId in android.
  // appTitles: { 'google-maps': 'My custom Google Maps title' }, // optionally you can override default app titles
  // app: 'uber',  // optionally specify specific app to use
  directionsMode: 'walk', // optional, accepted values are 'car', 'walk', 'public-transport' or 'bike'
});

Notes:

• The sourceLatitude/sourceLongitude options only work if you specify both. Currently supports all apps except Waze.
• directionsMode works on google-maps and apple-maps (on the latter, bike mode will not work). Without setting it, the app will decide based on his own settings.

Or

Using the getApps function will return an array (GetAppResult[]) with the apps available on the smartphone:

type GetAppResult = {
  id: string;
  name: string;
  icon: NodeRequire;
  open: () => Promise<void>;
};

import {getApps, GetAppResult} from 'react-native-map-link';

const Demo = () => {
  const [availableApps, setAvailableApps] = useState<GetAppResult[]>([]);

  useEffect(() => {
    (async () => {
      const result = await getApps({
        latitude: 38.8976763,
        longitude: -77.0387185,
        title: 'The White House', // optional
        googleForceLatLon: false, // optionally force GoogleMaps to use the latlon for the query instead of the title
        alwaysIncludeGoogle: true, // optional, true will always add Google Maps to iOS and open in Safari, even if app is not installed (default: false)
        appsWhiteList: ['google-maps'], // optionally you can set which apps to show (default: will show all supported apps installed on device)
      });
      setAvailableApps(result);
    })();
  }, []);

  return (
    <React.Fragment>
      {availableApps.map(({icon, name, id, open}) => (
        <Pressable key={id} onPress={open}>
          <Image source={icon} />
          <Text>{name}</Text>
        </Pressable>
      ))}
    </React.Fragment>
  );
};
