<p>You need to include the <code>NSLocationWhenInUseUsageDescription</code> key in Info.plist to enable geolocation when using the app. Geolocation is enabled by default when you create a project with <code>react-native init</code>.</p>
|
||
<p>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.</p>
|
||
<p>If you are using CocoaPods for React Native, make sure to include the <code>RCTGeolocation</code> sub-podspec.</p>

<p>To request access to location, you need to add the following line to your app's <code>AndroidManifest.xml</code>:</p>
|
||
<p><code><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /></code></p>
|
||
<p>Android API >= 18 Positions will also contain a <code>mocked</code> boolean to indicate if position was created from a mock provider.</p>
|
||
<p>
|
||
Android API >= 23 Requires an additional step to check for, and request
|
||
the ACCESS_FINE_LOCATION permission using
|
||
the <a href="https://facebook.github.io/react-native/docs/permissionsandroid.html" target="_blank">PermissionsAndroid API</a>.
|
||
Failure to do so may result in a hard crash.
