模拟器上的 GPS 没有得到地理修复 - Android

I'm developing an application for the android OS, I'm just starting, but I can't get the GPS on the emulator to work. I've read on the internet that you need to send a geo fix to the emulator in order to enable the gps locationProvider. I'm both using the DDMS and telnet to try to send it, but logcat never tells me the it recived a new fix, and my apolication still sees the gps as disabled

这是我的代码

package eu.mauriziopz.gps;

import java.util.Iterator;
import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;

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

        LocationManager l =(LocationManager) getSystemService(Context.LOCATION_SERVICE);
        List<String> li = l.getAllProviders();
        for (Iterator<String> iterator = li.iterator(); iterator.hasNext();) {
            String string =  iterator.next();
            Log.d("gps", string);
        }
        if (l.getLastKnownLocation("gps")==null)
            Log.d("gps", "null");   
    }
}

我听说 DDMS 在非英语操作系统上可能无法正常工作，但 telnet 应该可以工作！
