Android的;地理codeR，为什么会＆QUOT;服务不可用＆QUOT;？ [英] Android; Geocoder, why do I get "the service is not available"?

问题描述

我要使用的地理codeR在Android应用程序中，我得到了下面这段code来样吧：

I want to use the Geocoder in an android application, I've got the following piece of code to sample it :

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();
        }
    }
}

我碰到下面的堆栈跟踪：

I get the following stack trace :

为什么是服务不可用？我在清单以下

Why is the service unavailable? I have the following in my manifest

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

借助文档规定：的地理codeR类需要未包含在核心Android框架后端服务，如何/我在哪里可以得到这样的服务？

The documentation states : The Geocoder class requires a backend service that is not included in the core android framework, how/where can I obtain such a service?

推荐答案

这是在仿真器2.2中的错误 <一href="http://$c$c.google.com/p/android/issues/detail?id=8816">http://$c$c.google.com/p/android/issues/detail?id=8816

It's a bug in the emulator for 2.2 http://code.google.com/p/android/issues/detail?id=8816
