  distanceInterval:500,
});

Hey @iamvijay,

Can you share the full code relevant to the location code? It looks like you just have a snippet of your function above.

Cheers,
Adam

async fetchBackGroundLocation() {

const {status, permissions} = await Permissions.askAsync(Permissions.LOCATION);
if (status === 'granted') {
await Location.startLocationUpdatesAsync(LOCATION_TRACKER, {
	accuracy: Location.Accuracy.BestForNavigation, distanceInterval:500,
});
} else {
dispatch(fetchLocationError());
throw new Error('Location permission not granted');

}

TASK

if (!TaskManager.isTaskDefined(‘geofence’)) {
TaskManager.defineTask(LOCATION_TRACKER, ({ data, error }) => {
if (error) {
console.log(error)
// Error occurred - check error.message for more details.
return;
}
if (data) {
const { locations } = data;

  console.log('latitude>>',locations[0].coords.latitude +'<<longitude>>'+locations[0].coords.longitude)
  console.log('token in Task ',token)

}
})};
