【问题描述】：

我的问题是，当我运行应用程序时，它在应用程序的左上角显示 Google 图标，在活动中显示小灰色，但它不显示谷歌地图。任何人都可以通过智能解决这个问题吗？我参考了很多网站？

 public class MapsActivity extends FragmentActivity implements  OnMapReadyCallback {
 GoogleMap mMap;
 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.animateCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
