How do I request permission for Android Device Location in React Native at run-time?

Question

I have been trying to use React Native \'s GeoLocalisation for an Android App. The poorly documentated module is found here https://facebook.github.io/react-native/docs/geol

Answer 1

I solved it by changing the targetSdkVersion ( same to compileSdkVersion, in my case 23) in android/app/build.gradle.

Edit AndroidManifest.xml located in android/src/main and add the

next :

import { PermissionsAndroid } from 'react-native';

and then add this method:

export async function requestLocationPermission() 
{
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
      {
        'title': 'Example App',
        'message': 'Example App access to your location '
      }
    )
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log("You can use the location")
      alert("You can use the location");
    } else {
      console.log("location permission denied")
      alert("Location permission denied");
    }
  } catch (err) {
    console.warn(err)
  }
}

and access the method when you request the location at run-time

async componentWillMount() {
    await requestLocationPermission()
}
