我正在制作一个Android地图应用程序，使用goggle maps v2，alla一直运行直到我运行应用程序，它崩溃了。这是我的档案：
MainActivity.java
package com.geo.app;
import android.app.Activity;
import android.app.Fragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
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 MainActivity extends FragmentActivity {
static final LatLng HAMBURG = new LatLng(53.558, 9.927);
static final LatLng KIEL = new LatLng(53.551, 9.993);
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map=((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
.title("Hamburg"));
Marker kiel = map.addMarker(new MarkerOptions()
.position(KIEL)
.title("Kiel")
.snippet("Kiel is cool")
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.ic_launcher)));
// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}
}
activity_main.xml中

答案 0 :(得分：1)
在MainActivity.java类中更改片段导入语句
import android.support.v4.app.Fragment
答案 1 :(得分：1)
您在清单文件中缺少元标记
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
您不需要这些
<permission
android:name="com.geo.app.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
最好在初始化GoogleMap对象之前检查Google Play服务的可用性
编辑：
java.lang.NoClassDefFoundError：com.google.android.gms.R $ styleable
您尚未在Android地图项目中引用Google Play服务库项目。
