java.lang.NullPointerException: Location doesn't exist

[jayeshbabuav]

When I run the following code,

geoFirestore.getLocation(getItem("documentId", new GeoFirestore.LocationCallback()
                {
                    @Override
                    public void onComplete(GeoPoint geoPoint, Exception e)
                    {
                           e.printStackTrace();
                    }
                });

I get this exception:

My setLocation() works fine and location is getting entered in database fine.

What's doing the function getItem()?

[jayeshbabuav]

sorry I forgot to remove that getItem() while copying the code:

geoFirestore.getLocation("documentId", new GeoFirestore.LocationCallback()
                {
                    @Override
                    public void onComplete(GeoPoint geoPoint, Exception e)
                    {
                           e.printStackTrace();
                    }
                });

this is the actual code

[Lorenzo Calisti]

The function returns a NullPointerException because the queried geolocation is null; this can depend on two factors:

1. In the database, your data is not set correctly with "l" and "g" fields
2. The "l" field of your data is not correctly set, it needs to be a GeoPoint or a List<Double>

I am facing same issue and I've checked my firestore database there is entry of l and g

I've write this code, Let me know if I made any mystake

geoFirestore.getLocation(documentId, object : GeoFirestore.LocationCallback {
            override fun onComplete(geoPoint: GeoPoint?, exception: Exception?) {
                if(exception == null &&geoPoint!=null ){
				}
				else{
				}
				}
				  })
