این هم کد برنامه که خط 27         map.setMapType(GoogleMap.MAP_TYPE_SATELLITE); هست

 package com.uncocoder.course.app.google_maps;

import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;


public class GoogleMapsActivity extends FragmentActivity {

    private GoogleMap map;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        map.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

        networkLocation();
    }


    private void animateToLocation(double latitude, double longtitude) {
        LatLng latlng = new LatLng(latitude, longtitude);
        CameraPosition position1 = CameraPosition.builder()
                .target(latlng)
                .zoom(15)
                .build();

        map.animateCamera(CameraUpdateFactory.newCameraPosition(position1));
        map.addMarker(new MarkerOptions()
                .title("Test")
                .position(latlng));

    }


    public void networkLocation() {
        G.locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new LocationListener() {

            public void onLocationChanged(Location location) {
                animateToLocation(location.getLatitude(), location.getLongitude());
            }


            public void onStatusChanged(String provider, int status, Bundle extras) {}


            public void onProviderEnabled(String provider) {}


            public void onProviderDisabled(String provider) {}
        });
    }
}

این هم کلاس G

 package com.uncocoder.course.app.google_maps;

import android.app.Application;
import android.content.Context;
import android.location.LocationManager;


public class G extends Application {

    public static LocationManager locationManager;


    @Override
    public void onCreate() {
        super.onCreate();

        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    }
}

این هم سایر موارد
