学习Service过程中遇到生命周期LifeCycle问题，求助
--------------------编程问答-------------------- 没用过bindService这种方式启service，用这种方式启动的service会随着activity的销毁而销毁--------------------编程问答--------------------
整个过程中我的activity始终都处于前端，应该不是这个。
继续期待...
--------------------编程问答-------------------- 这是service的机制，死的东西 --------------------编程问答--------------------
我可以表达的不是很完整
为了清楚的看到Service是如何运作的，我在每个回调函数中都输出字串来跟踪
我现在是只调用bindService（）方法，而 没有 调用unBindService（）
但我的LOG中依旧显示的是onCreate()-->onBind()-->onUnbind()-->onDestroy()
按正常来说，后两个方法是不会自动调用的
奇怪就奇怪在这里 --------------------编程问答-------------------- 另外我把Activity的代码也帖出来，希望有哪位可以帮忙看看

switch (v.getId()) {
case R.id.button1:
startService(intent);
break;
case R.id.button2:
stopService(intent);
break;
case R.id.button3:
bindService(intent, sconn, Context.BIND_AUTO_CREATE);

--------------------编程问答-------------------- 我自己找到原因啦，丢人哇
switch--case中bindService后忘了break
结贴。 --------------------编程问答-------------------- 没事
粗心而已
每个人都犯 --------------------编程问答-------------------- 还是不能结贴啊 还以为到此就结束了呢 没想到unbindService（sconn）这样又有问题了
按照我5楼sconn那样实例化，unbindService（sconn）会异常，说我没有注册Service
实际上我在AndroidManifest.xml中是注册了的，又要头大了，求解？！

--------------------编程问答-------------------- ServiceConnection sconn = new ServiceConnection() {
不能作为方法里的局部变量，应该定义为类变量。否则每次按钮onClick都会产生新对象 --------------------编程问答--------------------
同样的错误.
--------------------编程问答-------------------- 在MAANIFEST。xml里 如何加权限啊？
--------------------编程问答-------------------- 有时候一个小错误 就是这样啊，但是楼主貌似没有结果贴啊？
补充：移动开发 , Android
