Answer 1

Write a class

public class MyLocationListener implements LocationListener {
        /**
         * This function handles location change event if location is found
         */
        public void onLocationChanged(Location loc) {...

Now, whenever you’ll get some GPS location, it’ll come inside onLocationChanged() method.

Do not forget to add the following permissions in your manifest-

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Also make sure you are adding both the location listeners GPS as well as Network like-

locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                0, locListener);
