public interface LocationCallback
LocationCallback
is used to run code after a Location has been fetched by
ParseGeoPoint.getCurrentLocationInBackground(long, android.location.Criteria)
.
The easiest way to use a LocationCallback
is through an anonymous inner class. Override the
done
function to specify what the callback should do after the location has been
fetched. The done
function will be run in the UI thread, while the location check
happens in a background thread. This ensures that the UI does not freeze while the fetch happens.
For example, this sample code defines a timeout for fetching the user's current location, and
provides a callback. Within the callback, the success and failure cases are handled differently.
ParseGeoPoint.getCurrentLocationAsync(1000, new LocationCallback() { public void done(ParseGeoPoint geoPoint, ParseException e) { if (e == null) { // do something with your new ParseGeoPoint } else { // handle your error e.printStackTrace(); } } });
