Android Google MapV2 не работает на intellijIdea

Question

Это мой основной класс

package com.example.mapv2example; 

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.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 MyActivity 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.main); 

     map = ((MapFragment) getFragmentManager().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); 
    } 

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


}

Я работы на IntellijIdea 12, и я добавляю библиотеку поддержки android и сервисы google play, но когда я пытаюсь запустить эмулятор приложения «к сожалению, mapv2example остановился», я получаю карту v ersion 2 апи ключ от Google и это мой журнал ошибок

Answer 1

ли вы компилировать должным образом сервисы Google Play в вашем build.gradle ... вы можете следовать инструкциям на сайте разработчиков Android ... http://developer.android.com/google/play-services/setup.html. .. и, возможно, вам придется использовать gmaps api v3 ...
