Geolocation #

The Geolocation API extends the web spec: https://developer.mozilla.org/en-US/docs/Web/API/Geolocation

As a browser polyfill, this API is available through the navigator.geolocation global - you do not need to import it.

Configuration and Permissions #

iOS #

You need to include the NSLocationWhenInUseUsageDescription key in Info.plist to enable geolocation when using the app. Geolocation is enabled by default when you create a project with react-native init.

In order to enable geolocation in the background, you need to include the 'NSLocationAlwaysUsageDescription' key in Info.plist and add location as a background mode in the 'Capabilities' tab in Xcode.

Android #

To request access to location, you need to add the following line to your app's AndroidManifest.xml:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Android API >= 18 Positions will also contain a mocked boolean to indicate if position was created from a mock provider.

Methods #

static getCurrentPosition(geo_success, geo_error?, geo_options?) #

Invokes the success callback once with the latest location info. Supported options: timeout (ms), maximumAge (ms), enableHighAccuracy (bool) On Android, if the location is cached this can return almost immediately, or it will request an update which might take a while.

static watchPosition(success, error?, options?) #

Invokes the success callback whenever the location changes. Supported options: timeout (ms), maximumAge (ms), enableHighAccuracy (bool), distanceFilter(m)

static clearWatch(watchID) #

static stopObserving() #
