我是 android 编程的新手，我已经浏览了 android 开发者指南和 YouTube 指南，还检查了这里提出的其他类似问题，但仍然无法在 AVD 模拟器上加载地图。我还导入了 google-play-services_lib 和 Android 构建目标：Android 4.2.2 API 17

我能够在模拟器上成功安装我的应用程序，但每次我尝试运行它时，它都会发出“不幸的是，[app] 已停止”的通知。

任何帮助的尝试将不胜感激。这是我的代码：

Google Play 服务目前不适用于虚拟设备，尽管通过谷歌搜索，似乎有办法绕过它。

最好的办法是在有可用设备的情况下使用真实设备，并确保安装 Google Play 服务 :)

谷歌地图在真实设备上运行，它不会在模拟器上运行，所以如果它不能在真实设备上运行，请在真实设备上尝试，然后尝试此代码，您还可以正确检查您是否在项目属性中添加了 googleplay 库

public class MainActivity extends Activity implements LocationListener{
LocationManager locationManager;
private GoogleMap googleMap;
double latitude=17.385044;
double longitude=78.486671;
private String provider;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
 LocationManager service=(LocationManager)getSystemService(LOCATION_SERVICE);
boolean enableGPS= service.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean enableWifi=service.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
 // Check if enabled and if not send user to the GSP settings
    // Better solution would be to display a dialog and suggesting to 
     // go to the settings
 if(!enableGPS){
     Toast.makeText(getApplicationContext(),"Gps signal not found",1).show();
    Intent intent=new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
    startActivity(intent);
}
locationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
 Criteria criteria = new Criteria();
 provider = locationManager.getBestProvider(criteria, false);
 Location location = locationManager.getLastKnownLocation(provider);

 // Initialize the location fields
 if (location != null) {
     Toast.makeText(this, "Selected Provider " + provider,
             Toast.LENGTH_SHORT).show();
     onLocationChanged(location);
 } else {

     //do something
 }


try {
    //loading map
    initilizeMap();
} catch (Exception e) {
    // TODO: handle exception
e.printStackTrace();
}
}
   private void initilizeMap(){
if(googleMap==null){
googleMap=(MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();    
      //check if map is created succesfully or not
    if(googleMap==null){
  Toast.makeText(getApplicationContext(),"sorry unable to create map",0).show();  
    }
}

MarkerOptions markerOptions=new MarkerOptions().position(new LatLng(latitude, longitude)); markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher)); CameraPosition cameraPosition=new CameraPosition.Builder().target(new LatLng(17.385044, 78.486671)).zoom(12).build(); googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); googleMap.setMyLocationEnabled(true); googleMap.setOnInfoWindowClickListener(null); }

 @Override
  protected void onResume(){
super.onResume();
initilizeMap();
 }

/* Remove the locationlistener updates when Activity is paused */
@Override
protected void onPause() {
super.onPause();
locationManager.removeUpdates(this);
}

 public void onLocationChanged(Location location) {
double lat =  location.getLatitude();
double lng = location.getLongitude();
Toast.makeText(this, "Location " + lat+","+lng,
        Toast.LENGTH_LONG).show();
LatLng coordinate = new LatLng(lat, lng);
Toast.makeText(this, "Location " + coordinate.latitude+","+coordinate.longitude,
        Toast.LENGTH_LONG).show();
Marker startPerc = googleMap.addMarker(new MarkerOptions()
.position(coordinate)
.title("Start")
.snippet("Inizio del percorso")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher)));
}


  public void onProviderDisabled(String provider) {
  Toast.makeText(this, "Enabled new provider " + provider,
        Toast.LENGTH_SHORT).show();

   }


  public void onProviderEnabled(String provider) {
  Toast.makeText(this, "Disabled provider " + provider,
        Toast.LENGTH_SHORT).show();

     }


public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub

  }
