谷歌地图未在android中显示

我用android开发了一个应用程序，它使用谷歌地图显示用户所在位置附近的购物中心列表

这是我实现它的代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <org.fluturasymphony.recommendation.StoreMapView 
        android:id="@+id/mapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="0aHtkSh4B8Ub3ELLFUMRWJD23wpEWJAsFxL-ilw"
        />



</RelativeLayout>

但是当我运行模拟器时，我会看到一个像这样的空白屏幕。我怎样才能修好它

告诉我我做错了什么

嗨，我现在有一个日志猫错误

01-03 07:28:02.585:E/MapActivity（3823）：无法获取连接工厂客户端

01-03 07:30:26.165:E/MapActivity（12298）：无法获取连接工厂客户端
