由於;無法讓Geopoints添加到谷歌地圖;無法獲取連接工廠客戶端

Question

我在嘗試將多個Geopoint位置繪製到Google地圖上時出現此錯誤。我正在通過PHP和JSON從MySQL數據庫讀取經緯度。我看過主要的例子，如Couldn't get connection factory client,Couldn't get connection factory client - fighting with Google Maps,Android MapActivity : Couldn't get connection factory client。
我可以確認它不是無效的API密鑰，因爲我生成了2個不同的密鑰並返回了相同的錯誤。這也不是API級別的問題，我嘗試在API級別17和級別8上運行應用程序，但仍然沒有喜悅。當我運行的代碼，它顯示的地圖沒有問題，然後獲取到的「錯誤顯示內容的」我的異常敬酒消息
這裏是我的mapview.java代碼：

import java.util.ArrayList;

     is = entity.getContent(); 

    } 

    catch(Exception e) 
    { 
     Log.e("log_tag", "Error in http connection"+e.toString()); 
    } 


     try{   


     jarray = new JSONArray("$json_output[]"); 
     JSONObject json_data = null; 
       for(int i = 0; i < jarray.length(); i++) 
       { 
        json_data = jarray.getJSONObject(i); 

        LAT=json_data.getDouble("lat"); 
        LNG=json_data.getDouble("lng"); 

        GeoPoint point = new GeoPoint((int)(LAT * 1E6), (int)(LNG * 1E6)); 
        OverlayItem overlayitem = new OverlayItem(point, "TEXT", null); 

        List<Overlay> mapOverlays = mapview.getOverlays(); 
        Drawable drawable = this.getResources().getDrawable(R.drawable.marker); 
        myItemizedOverlay itemizedoverlay = new myItemizedOverlay(drawable, this); 

        MapController mapController = mapview.getController(); 

        //mapController.animateTo(point); 
        mapController.setZoom(8); 

        itemizedoverlay.addOverlay(overlayitem); 
        mapOverlays.add(itemizedoverlay); 
       } 
      } 
      catch(JSONException e1) 
      { 
      Toast.makeText(getBaseContext(), "Error displaying contents" ,Toast.LENGTH_LONG).show(); 
      }  
       catch (ParseException e1) 
       {

       } 
    } 
    @Override 
    protected boolean isRouteDisplayed() 
    { 
     return false; 
    }

這是我ItemizedOverlay.java代碼：

import java.util.ArrayList; 

    import android.app.AlertDialog; 
    import android.content.Context; 
    import android.graphics.drawable.Drawable; 

    import com.google.android.maps.OverlayItem; 
    import com.google.android.maps.ItemizedOverlay; 


    public class myItemizedOverlay extends ItemizedOverlay 
    { 

     private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>(); 
     private Context mContext; 

     public myItemizedOverlay(Drawable marker, Context context) 
     { 
      super(boundCenterBottom(marker)); 
      mContext = context; 

     } 

     public void addOverlay(OverlayItem overlay) 
     { 
      mapOverlays.add(overlay); 
      this.populate(); 
     } 


     @Override 
     protected OverlayItem createItem(int i) 
     { 
      return mapOverlays.get(i); 
     } 

     @Override 
     public int size() 
     { 
      return mapOverlays.size(); 
     } 

     @Override 
     protected boolean onTap(int index) 
     { 
      OverlayItem item = mapOverlays.get(index); 
      AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); 
      dialog.setTitle(item.getTitle()); 
      dialog.setMessage(item.getSnippet()); 
      dialog.show(); 
      return true; 
     } 

    } 

我希望得到任何幫助，我要提前致謝。

如果您最近生成了這些密鑰，您將無法獲得結果，因爲API v1已被棄用且無法使用。

您可能要切換到地圖API V2：https://developers.google.com/maps/documentation/android/

不要試圖用你的舊代碼，因爲新的API不共享API v1的任何代碼。
