Google Maps API

1) Start a project with Maps activity instead of blank

2) Set minimum API level to be atleast Marshmellow (6.0)

3) Enable Google Map SDK for android API in your cloud account and get the API key.

4) Place your API key in src/debug/res/values/google_maps_api.xml

Maps activity java

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
