Google Maps API 2 for Android「不幸的是，[app]已停止。」無法運行應用程序

Question

我是Android編程的新手，我已經運行了Android開發人員指南和YouTube指南，並且還檢查了其他類似的問題在這裏提出，但我仍然無法在AVD模擬器上加載地圖。我還引進谷歌播放，services_lib和 的Android構建目標：的Android 4.2.2 API 17

我能夠在仿真器，但每一次成功安裝我的應用程序，當我嘗試運行它，它會通知「不幸的是，[app]已停止。」

任何試圖幫助將不勝感激。 這裏是我的代碼：

manifest.xml文件：

    </RelativeLayout>

Answer 1

谷歌Play服務目前無法使用虛擬設備的，雖然有點谷歌搜索的，它看起來像有辦法一輪它。

最好的辦法是隻使用一個真正的設備，如果你有一個可用，並確保你安裝谷歌播放服務:)

Answer 2

真實設備

谷歌地圖來看，它不會在模擬器上運行實時所以嘗試如果它不會在真實的設備運行裝置那就試試這個代碼，你也好好檢查您在項目屬性添加GOOGLEPLAY庫

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(); 
    } 
} 

的MarkerOptions的MarkerOptions =新的MarkerOptions（）位置（新的經緯度（緯度，經度））; markerOptions.icon（BitmapDescriptorFactory.fromResource（R.drawable.ic_launcher））; （）新的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 

    }
