To get your current location via Google Map in an Android app, this was how we do it:

1 2 3 4 |
@Override public void onMapReady(GoogleMap googleMap) { Location location = googleMap.getMyLocation(); } |
Stop. Don’t use that! The method GoogleMap.getMyLocation() is deprecated. Instead, we need to use FusedLocationApi and the callback onLocationChanged().
Here’s an example code that works for me ( consider copying the contents of onResume() into onStart() ):
