谷歌地图拒绝显示

Question

我刚刚创建了一个新项目，并添加了API密钥，当我尝试运行该项目时，谷歌地图不会加载

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.

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

/**

*/
@Override
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));
}

}

这应该可以修复错误。
