安卓;地理编码器，为什么我得到 "the service is not available"？

Question

我想在 android 应用程序中使用 Geocoder，我有以下代码对其进行采样:

public class LocatorGeo extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        Geocoder geo = new Geocoder(getApplicationContext());

        List<Address> myAddrs = new ArrayList<Address>();

        try {
            myAddrs = geo.getFromLocationName("CO100AR", 1);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

我得到以下堆栈跟踪:

为什么服务不可用？我的 list 中有以下内容

   <uses-permission android:name="android.permission.INTERNET"/>

documentation状态:Geocoder 类需要一个不包含在核心 android 框架中的后端服务，我如何/在哪里可以获得这样的服务？
