Question

Maps activity have auto generated code:

public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }

Answer 1

Check if you have enabled maps for android in Google API Console . Check if you have followed all the steps mentioned in the Official Google Documentation . Your activity must extend FragmentActivity and to initialize GoogleMap object. Make sure you have added support library.

Try to create a map with this line:

MapFragment mMapFragment=MapFragment.newInstance(mapOptions());
