Question

我遇到了问题，我想将GoogleMap显示为片段。但是在启动应用程序时，地图会保持黑色。仅显示小型Google徽标。所以我这样做：

public class AndroidLauncher extends AndroidApplication implements RequestHandler,LocationListener,
    GoogleApiClient.ConnectionCallbacks, OnMapReadyCallback {

private MapFragment mMapFragment;

public GoogleMap googleMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.main);

    mMapFragment = ((MapFragment) getFragmentManager().findFragmentById(R.id.map));

    if (mMapFragment == null) {
        mMapFragment = (MapFragment) MapFragment.newInstance();

        mMapFragment.getMapAsync(this);


        FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();

        // flMap.getID(); returns the FrameLayout ID.

        fragmentTransaction.replace(flMap.getId(), mMapFragment, MAP_FRAGMENT_TAG);
        fragmentTransaction.commit();

    }

}

@Override
public void onMapReady(GoogleMap gMap) {

    googleMap = gMap;

    if (googleMap != null) {

        final LatLng markerPosition = new LatLng(26.9124857, -101.4180168);
        googleMap.addMarker(new MarkerOptions().position(markerPosition)).showInfoWindow();

    }

}

我只发布了最重要的东西，还有更多，比如精灵层，但我认为这不是问题......

当我启动应用程序时，我的地图看起来像这样黑：

它有什么问题：/？我已经在清单中添加了这样的API密钥：

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />
<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
