Android Fragments 如何在Android应用程序中显示谷歌Map

我想在我的应用程序中实现谷歌Map.我得到了MapAPI密钥，并在我的XML文件中使用它，但谷歌Map不显示。当我添加片段到XML文件，它会导致强制关闭错误，当我纠正这个错误，然后谷歌Map在运行时不显示。
MainActivity.java

package com.example.simplemap;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

public static class MapsFragment extends Fragment {

        private SupportMapFragment suppfrag;
        static final LatLng myLoc = new LatLng(//latitiude and longitude here);
        private GoogleMap map;

        public static final String ARG_SECTION_NUMBER = "section_number";

        public MapsFragment() {

        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

                return inflater.inflate(R.layout.fragment_map, container, false);
        }
        @Override
        public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            FragmentManager fm = getChildFragmentManager();
            suppfrag = (SupportMapFragment) fm.findFragmentById(R.id.map);
            if (suppfrag == null) {
                suppfrag = SupportMapFragment.newInstance();
                fm.beginTransaction().replace(R.id.map, suppfrag).commit();

                Marker location = map.addMarker(new MarkerOptions().position(CENTRU)
                        .title("Centru"));
                    location.setIcon(BitmapDescriptorFactory
                                        .defaultMarker(BitmapDescriptorFactory.HUE_BLUE));

                    // Move the camera instantly to Bottlecapp with a zoom of 15.
                    map.moveCamera(CameraUpdateFactory.newLatLngZoom(CENTRU, 15));

                    // Zoom in, animating the camera.
                    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
                    getActivity().getSupportFragmentManager().popBackStack();
            }
        }
        @Override
        public void onResume() {
            super.onResume();
            if (map == null) {
                map = suppfrag.getMap();
                map.addMarker(new MarkerOptions().position(new LatLng(0, 0)));
            }
        }
    }
