Service的开启和停止以及生命周期

1、清单文件

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

2、开启Service

Intent intent = new Intent(this, TestService.class);
startService(intent);

3、停止服务

Intent intent = new Intent(this, TestService.class);
stopService(intent);

4、Service的开启和停止所显示的生命周期

 package com.example.testservice;

 import android.app.Service;
 import android.content.Intent;
 import android.os.IBinder;

 public class TestService extends Service {

     @Override
     public IBinder onBind(Intent intent) {
         // TODO Auto-generated method stub
         return null;
     }

     @Override
     public void onCreate() {
         // TODO Auto-generated method stub--1
         System.out.println("onCreate");
         super.onCreate();

     }

     @Override
     @Deprecated
     public void onStart(Intent intent, int startId) {
         // TODO Auto-generated method stub--3
         System.out.println("onStart");
         super.onStart(intent, startId);

     }

     @Override
     public int onStartCommand(Intent intent, int flags, int startId) {
         // TODO Auto-generated method stub--2
         System.out.println("onStartCommand");
         return super.onStartCommand(intent, flags, startId);

     }

     @Override
     public void onDestroy() {
         // TODO Auto-generated method stub--4
         System.out.println("onDestroy");
         super.onDestroy();
     }

 }

注意:--n显示是它们的执行顺序
