显示地图错误

Question

尝试在项目中使用MapView显示地图时收到此错误消息。我已经长时间注册了Map API v1密钥，并且我还使用了我的指纹来重新生成apikey，但我仍然收到错误消息“：无法获得连接工厂客户端”

以下是我的开发环境： android ver.:2.3.3 JRE：1.6

下面的代码也包含在我的AndroidManifest.xml

中

 <uses-library android:name="com.google.android.maps"/>       
<uses-permission android:name="android.permission.INTERNET" />

I would like to know what is wrong because the project is actually an example code in my books, which can be downloaded [here][1] - title is "Chap8-Where Am I 4".
