我有一个旧应用程序，我正在尝试更新以添加地图。Google-services 在 Eclipse 中添加到我的工作区，并在我的项目中创建为库引用。清单中添加的 Mapkey 和权限。

我阅读了很多教程，但我无法解决以下问题：

我的活动：

package com.example.data.activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.example.data.R;

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.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity {
  private LatLng frameworkSystemLocation = new LatLng(-19.92550, -43.64058);
  private GoogleMap map;

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);
    map =   ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    Marker frameworkSystem = map.addMarker(new MarkerOptions()
                                           .position(frameworkSystemLocation)
                                           .title("Framework System"));
 // Move a câmera para Framework System com zoom 15.
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(frameworkSystemLocation , 15));
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    // getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
  }

}

我的 xml 布局文件： 

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.MapFragment" />

</RelativeLayout>

有谁知道如何解决？

您是否还更改了 XML 布局中的地图？

应该是这样的：

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="8dp" />
