问题
I know same question is already asked here in 2016 but I tried those and they are not working at all. I tried Stop Location Updates after first time and I tried method that are told in this.
I want to stop location update once it get location. removeUpdate is not working.
I had tried this code in onLocationChanged() method mLocationManager.removeUpdates(mListener); but it never works. removeUpdate comes in red.
Please suggest me what should I do and plz watch my code and see what I have used and accordingly answer please.
Thank you in advance.
