谷歌地图v2 api不跟踪用户位置

Question

For some reason my MapFragment won't show the user location anymore? Map tiles are still displayed but it's not displaying current location??

         public class MyTask extends AsyncTask<Void, Void, Void>{

                protected void onPreExecute() {

                    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                            .getMap();
                    map.moveCamera(CameraUpdateFactory.newLatLngZoom(place, 4000));
                    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
                    map.setMyLocationEnabled(true);
                    map.getUiSettings().setZoomControlsEnabled(true);
                    map.getUiSettings().setMyLocationButtonEnabled(true);
                    map.setTrafficEnabled(true);
                    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);


            }

This is my basic MapFragment which normally worked until i started testing on another Android device which uses the same android version only difference is theres no SIM card in the device. Does that make a difference??

I have no idea how the api has stopped working. Any feedback appreciated

Answer 1

Yes, sim card absence could be an issue. I have the same trouble wasn't able to get location without sim card (no SIM - no network location provider), because GPS location provider couldn't determine location indoors.
