2010.12.27——— android service

参考：http://apps.hi.baidu.com/share/detail/23409277

需求：在应用开启时，启动一个service 不断的获得当前的gps数据

代码：

service：

package com.huitu.project;

import java.io.IOException;

import org.apache.http.client.ClientProtocolException;

import com.huitu.util.HttpUtil;

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;

public class GPSService extends Service{
	private String user_id;

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		LocationManager locationManager; locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
		user_id = intent.getStringExtra("user_id");
		String provider = LocationManager.GPS_PROVIDER;
		Location location = locationManager.getLastKnownLocation(provider);
		
		updateMap(location,user_id);
		
		LocationListener ll = new LocationListener(){
			public void onLocationChanged(Location location) {
				updateMap(location,user_id);
			}
			public void onProviderDisabled(String provider) {
			}

			public void onProviderEnabled(String provider) {
			}

			public void onStatusChanged(String provider, int status,
					Bundle extras) {
			}
         };
		
		locationManager.requestLocationUpdates(provider, 500, 5,
				ll);
		return null;
	}

	@Override
	public void onCreate() {
		// TODO Auto-generated method stub
		super.onCreate();
	}

	@Override
	public void onStart(Intent intent, int startId) {
		// TODO Auto-generated method stub
		super.onStart(intent, startId);
		
	}
	private void updateMap(Location location,String user_id){
		System.out.println("gps run");
		double lat=0.0;
		double lng = 0.0;
		if (location != null) {
			 lat = location.getLatitude();
			 lng = location.getLongitude();
		}
		String url = HttpUtil.BASE_URL+"android_addGPS_M.action?lat="+lat+"&lng="+lng+"&user_id="+user_id;
		try {
			HttpUtil.getHttpResponse(HttpUtil.getHttpPost(url));
		} catch (ClientProtocolException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
	

}

清单文件：

<service android:name=".GPSService"></service>

调用：

Intent service = new Intent(this,GPSService.class);
				service.putExtra("user_id", result[1]);
				intent.putExtra("user_id", result[1]);
				intent.putExtra("org_id", result[2]);
				//startService(service);
				bindService(service, null, BIND_AUTO_CREATE);

总结：

• startService：应用退出了 仍然运行 比如说mp3的播放
• bindService 应用退出 也就结束了
