public abstract class LocationCallback extends Object
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();
}
}
});
