我希望有人可以帮助我解决在 Eclipse 中将模拟 GPS 数据发送到 Android AVD 时遇到的问题。如果我在真实设备上运行应用程序，一切正常，但是当我尝试在 eclipse 中使用内置模拟器时，什么都不会发生。我也尝试过远程登录到 AVD 并发出 geo fix 命令。下面是我正在使用的代码，虽然我认为如果它在真实设备上运行没有什么问题

清单文件

主要代码

package net.TestGoogleMaps;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

public class TestingGoogleMapsActivity extends Activity 
{

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

        LocationManager locationManager; 
        String context = Context.LOCATION_SERVICE; 
        locationManager = (LocationManager)getSystemService(context); 
        Criteria criteria = new Criteria(); 
        criteria.setAccuracy(Criteria.ACCURACY_FINE); 
        criteria.setAltitudeRequired(false); 
        criteria.setBearingRequired(false); 
        criteria.setCostAllowed(true); 
        criteria.setPowerRequirement(Criteria.POWER_LOW); 
        String provider = locationManager.getBestProvider(criteria, true); 

        Location location = locationManager.getLastKnownLocation(provider); 


        updateWithNewLocation(location);


        locationManager.requestLocationUpdates(provider, 2000, 10,    
                                               locationListener); 
    }



    private final LocationListener locationListener = new LocationListener() { 
        public void onLocationChanged(Location location) { 
          updateWithNewLocation(location); 
        } 

        public void onProviderDisabled(String provider){ 
          updateWithNewLocation(null); 
        } 

        public void onProviderEnabled(String provider){ } 
        public void onStatusChanged(String provider, int status,  
                                    Bundle extras){ } 
      };




    public void updateWithNewLocation(Location location)
    {

        Context contextApp = getApplicationContext();

        String text ;
        int duration = 2000;

        if(location == null)
        {
            text ="Null Location";

        }
        else
        {
            text = "Lat : " + location.getLatitude() + " Lon: " + location.getLongitude();
        }

        Toast toast = Toast.makeText(contextApp, text, duration);
        toast.show();
    }   
}

在 eclipse 的 LogCat 选项卡中模拟 GPS 数据从 eclipse 到设备时，有时也会出现以下错误。

05-31 02:31:35.158: E/InputQueue-JNI(347): channel '406e6640  net.TestGoogleMaps/net.TestGoogleMaps.TestingGoogleMapsActivity (client)' ~ Publisher closed input channel or an error occurred.  events=0x8

任何帮助将不胜感激！

我知道您的问题，您可以手动设置当前（长/滞后）

DDMS->Devices->Emulator Control->Location Controls->Manual->input (Long/Lag) and SEND

正如 Tanvir Ahmed 所说，它看起来像是一个错误（来源）。我也为此绊倒了一天多。您可以尝试的是，对 AVM 使用“Google APIs - API Level 10”而不是“Android 2.3.3”。
