從Google Maps API v2更新Google Play服務中的崩潰MapView

Question

在我的Android項目中，我有一個MapView（API v2），可以在最近的設備上正常工作（S. Galaxy S3，Google Play Services是最新的），但如果我在舊設備上試用（LG-C550，Google Play服務不是最新的），我會通過一個按鈕來獲取錯誤消息來更新服務。問題在於點擊它後應用程序崩潰。

的運行時異常來自於谷歌地圖視圖（由庫創建），嘗試啓動谷歌從我的應用程序上下文播放服務更新不FLAG_ACTIVITY_NEW_TASK。

您認爲是否有辦法糾正Google Play庫引發的此異常？

我MapActivity類：

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.RelativeLayout; 

import com.google.android.gms.maps.MapView; 

public class MapActivity extends Activity { 

    private MapView mapView = null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(new RelativeLayout(getApplicationContext()) { 
      { 
       addView(mapView = new MapView(getApplicationContext()) { 
        { 
         setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); 
        } 
       }); 
      } 
     }); 
     mapView.onCreate(savedInstanceState); 
    } 

    @Override 
    protected void onDestroy() { 
     super.onDestroy(); 
     mapView.onDestroy(); 
    } 

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

    @Override 
    protected void onPause() { 
     super.onPause(); 
     mapView.onPause(); 
    } 

    @Override 
    public void onLowMemory() { 
     super.onLowMemory(); 
     mapView.onLowMemory(); 
    } 

    @Override 
    protected void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 
     mapView.onSaveInstanceState(outState); 
    } 

}

，我發現我的錯誤與此谷歌論壇主題：https://groups.google.com/d/msg/google-admob-ads-sdk/Nb1kCQB4fJo/m7rQQD9CLIEJ

我不得不放棄活動情境，而不是應用程序上下文創建MapView類的實例：

addView(mapView = new MapView(getApplicationContext()) { 

替換爲：

addView(mapView = new MapView(MapActivity.this) { 

如果Google團隊看到這篇文章，請問您是否可以在您的文檔中將其精確到：https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/MapView.html?hl=fr#MapView(android.content.Context)？我認爲這非常重要
