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.
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.
