Expo MapsAsk AI
A library that provides access to Google Maps on Android and Apple Maps on iOS.
Ask AI
Android
iOS
Bundled version:
~0.12.8
Copy page
This library is currently in alpha and will frequently experience breaking changes. It is not available in the Expo Go app – use development builds to try it out.
Terminal
Copy
- npx expo install expo-maps
If you are installing this in an existing React Native app
, make sure to install expo
in your project.
Expo Maps provides access to the platform native map APIs on Android and iOS.
Apple Maps (available on
iOS
only). No additional configuration is required to use it after installing this package.
Google Maps (available on
Android
only). While Google provides a Google Maps SDK for iOS, Expo Maps supports it exclusively on Android. If you want to use Google Maps on iOS, you can look into using an alternative library or writing your own .
Before you can use Google Maps on Android, you need to register a Google Cloud API project, enable the Maps SDK for Android, and add the associated configuration to your Expo project.
If you have already registered a project for another Google service on Android, such as Google Sign In, you enable the Maps SDK for Android on your project and jump to step 4.
1
Register a Google Cloud API project and enable the Maps SDK for Android
2
Copy your app's SHA-1 certificate fingerprint
For Google Play Store
For development builds
If you are deploying your app to the Google Play Store, you'll need to upload your app binary to Google Play console at least once. This is required for Google to generate your app signing credentials.
Go to the Google Play Console
(your app) > Test and release > App integrity > Play app signing > Settings > App signing key certificate.
Copy the value of SHA-1 certificate fingerprint.
If you have already created a development build , your project will be signed using a debug keystore.
After the build is complete, go to your project's dashboard , then, under Project settings > click Credentials.
Under Application Identifiers, click your project's package name and under Android Keystore copy the value of SHA-1 Certificate Fingerprint.
3
Create an API key
android.package from app.json (for example: com.company.myapp) to the package name field.4
Add the API key to your project
android.config.googleMaps.apiKey field.expo-maps.To display the user's location on the map, you need to declare and request location permission beforehand. You can configure this using its built-in config plugin if you use config plugins in your project (Continuous Native Generation (CNG) ). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect. If your app does not use CNG, then you'll need to manually configure the library.
app.json

| Name | Default | Description |

To show the user's location on the map, the expo-maps library requires the following permissions:
ACCESS_COARSE_LOCATION: for approximate device locationACCESS_FINE_LOCATION: for precise device location| Android Permission | Description |
| --- | --- |
| ACCESS_COARSE_LOCATION | Allows an app to access approximate location.<br><br>> Alternatively, you might want [ACCESS_FINE_LOCATION](https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION) . |
| ACCESS_FINE_LOCATION | Allows an app to access precise location.<br><br>> Alternatively, you might want [ACCESS_COARSE_LOCATION](https://developer.android.com/reference/android/Manifest.permission#ACCESS_COARSE_LOCATION) . |
| FOREGROUND_SERVICE | Allows a regular application to use Service.startForeground.<br><br>> Allows a regular application to use [Service.startForeground](https://developer.android.com/reference/android/app/Service#startForeground(int,%20android.app.Notification)) . |
| FOREGROUND_SERVICE_LOCATION | Allows a regular application to use Service.startForeground with the type "location".<br><br>> Allows a regular application to use [Service.startForeground](https://developer.android.com/reference/android/app/Service#startForeground(int,%20android.app.Notification)) with the type "location". |
| ACCESS_BACKGROUND_LOCATION | Allows an app to access location in the background.<br><br>> If you're requesting this permission, you must also request either [ACCESS_COARSE_LOCATION](https://developer.android.com/reference/android/Manifest.permission#ACCESS_COARSE_LOCATION) or [ACCESS_FINE_LOCATION](https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION) . Requesting this permission by itself doesn't give you location access. |
The following usage description keys are used by this library:
| Info.plist Key | Description |
